Description

Technical Field

[0002] Electrochromism refers to the reversible color change of materials under the influence of an external electric field. Essentially, electrochromism involves a redox reaction in the material under the influence of an external electric field and current, leading to structural changes and consequently altering its absorption spectrum and optical properties (such as absorptivity, transmittance, and reflectivity). This manifests as reversible changes in color and transparency. In recent years, electrochromic devices have been widely used in energy-saving windows, automotive rearview mirrors, display devices, and mobile terminals, demonstrating promising market prospects.

[0003] Electrochromic materials are highly sensitive, thus requiring strict sealing. Current technology typically involves applying a sealant around the perimeter of the electrochromic device to prevent moisture or other substances from entering and damaging the material, leading to device failure.

[0056] Currently, electrochromic devices are widely used in energy-saving windows, automotive rearview mirrors, display devices, mobile terminals, and other fields, showing promising market application prospects. The essence of electrochromism is that materials undergo oxidation-reduction reactions under the influence of an external electric field and current, leading to structural changes and consequently altering their absorption spectrum and optical properties (such as absorptivity, transmittance, and reflectivity). This manifests as reversible changes in color and transparency.

[0057] Electrochromic materials are highly sensitive, thus requiring strict sealing. Current technology typically involves applying a sealant around the perimeter of the electrochromic device to prevent moisture or other substances from entering and damaging the material, leading to device failure. However, this requires additional sealing, increasing manufacturing steps and reducing efficiency.

[0058] Based on this, to solve the above problems, this application designs an electrochromic device. A first conductive connector is bonded to the peripheral edge of the electrochromic device on either side of the stacking direction via an adhesive layer, making installation convenient and quick. The conductive layer of the first conductive connector on either side, under the action of the insulating and conductive portions, can form an electrical connection only with the first conductive base layer of the first conductive substrate or the second conductive base layer of the second conductive substrate, allowing the conductive layer to form electrodes and facilitating connection of the electrochromic device to an external power source. Simultaneously, the insulating portion covers both the first and second conductive substrates along the first direction, enabling the first conductive connector to also seal the side of the electrochromic layer, preventing moisture or other substances from entering the interior of the electrochromic device from the side, thus improving product reliability. In other words, the conductive component can simultaneously serve the dual function of forming device electrodes and sealing the side of the device, eliminating the need for additional sealing adhesive at the peripheral edge of the electrochromic device. This ingenious structural design reduces manufacturing steps and improves production efficiency.

[0059] Please refer to Figure 1 , Figure 2, Figure 3 The electrochromic device 1000 provided in the first aspect of this application includes a conductive component 1 and a first conductive substrate layer 2, an electrochromic layer 3, and a second conductive substrate layer 4 stacked sequentially. The conductive component 1 is disposed at the peripheral edge of at least one of the first conductive substrate layer 2 and the second conductive substrate layer 4. The conductive component 1 includes a first conductive connector 5, which includes a conductive layer 501 and an adhesive layer 502 stacked together. The adhesive layer 502 includes an insulating portion 5021 and a conductive portion 5022. The conductive layer 501 is electrically connected to the first conductive substrate layer 2 through the conductive portion 5022, and the conductive layer 501 is insulated from the second conductive substrate layer 4 through the insulating portion 5021. And / or, the conductive layer 501 is electrically connected to the second conductive substrate layer 4 through the conductive portion 5022, and the conductive layer 501 is insulated from the first conductive substrate layer 2 through the insulating portion 5021.

[0060] Understandably, Figure 1 This is a top view of the electrochromic device 1000 according to an embodiment of this application. In the stacking direction Y of the first conductive substrate layer 2, the electrochromic layer 3, and the second conductive substrate layer 4, the overlapping area of ​​the first conductive substrate layer 2 and the second conductive substrate layer 4 covers the electrochromic layer 3, so that the electrochromic layer 3 is not exposed outside the electrochromic device 1000, thus effectively protecting the electrochromic layer 3.

[0061] The electrochromic layer 3 is made of electrochromic material and exhibits a stable and reversible color change under the influence of an applied electric field. The electrochromic layer 3 is a sheet composed of one or more layers of gel-state or solid materials, such as polymer-dispersed liquid crystal (PDLC) layers, suspended particle device (SPD) layers, and electrochromic (EC) layers. For electrochromic (EC) type electrochromic layers 3, it may include a color-changing material layer, an electrolyte layer, and an ion storage layer stacked sequentially. The materials of the color-changing material layer, electrolyte layer, and ion storage layer can be those available in the prior art, and this application does not impose any special limitations on them.

[0062] In some embodiments, reference Figure 4The first conductive substrate layer 2 includes a first substrate layer 21 stacked together and a first conductive base layer 22 disposed on the surface of the first substrate layer 21; the second conductive substrate layer 4 includes a second substrate layer 41 stacked together and a second conductive base layer 42 disposed on the surface of the second substrate layer 41; the first substrate layer 21 of the first conductive substrate layer 2 is disposed on the side of the first conductive base layer 22 away from the electrochromic layer 3; or the second substrate layer 41 of the second conductive substrate layer 4 is disposed on the side of the second conductive base layer 42 away from the electrochromic layer 3.

[0063] Preferably, the first substrate layer 21 and the second conductive substrate layer 4 are made of transparent and flexible substrates with light transmittance, such as polyethylene glycol terephthalate (PET), polycarbonate (PC), etc., and can also be made of glass substrates; the first conductive base layer 22 and the second conductive base layer 42 are made of indium-tin oxide (ITO), aluminum zinc oxide (AZO), fluorine-doped tin oxide (FTO), and the first conductive base layer 22 and the second conductive base layer 42 are preferably made of ITO; so that both the first conductive substrate layer 2 and the second conductive substrate layer 4 have good conductivity and light transmittance.

[0064] refer to Figure 2 , Figure 3 At the peripheral edge of the electrochromic device 1000, a portion that does not overlap in the stacking direction Y is formed between the first conductive substrate layer 2 and the second conductive substrate layer 4; the conductive component 1 can be disposed on the first conductive base layer 22 of the first conductive substrate layer 2 to form an electrical connection with the first conductive substrate layer 2, and / or, the conductive component 1 can be disposed on the second conductive base layer 42 of the second conductive substrate layer 4 to form an electrical connection with the second conductive substrate layer 4.

[0065] Specifically, Figure 2 for Figure 1A cross-sectional view of the electrochromic device 1000 along the BB direction shows that the conductive component 1 includes a first conductive connector 5. The first conductive connector 5 includes a conductive layer 501 and an adhesive layer 502 stacked together. The conductive layer 501 is conductive and is made of conductive materials such as, but not limited to, copper foil, silver wire, and conductive resin. The adhesive layer 502 is adhesive, and the conductive layer 501 and the adhesive layer 502 are stacked and connected to form an integral structure. Both the conductive layer 501 and the adhesive layer 502 are composite layers with good ductility. The specific number of layers is not limited here. The first conductive connector 5 can be quickly bonded to the first conductive substrate layer 2 or the second conductive substrate layer 4 through the adhesive layer 502, making the first conductive connector 5 easy and quick to install.

[0066] The adhesive layer 502 further includes an insulating portion 5021 and a conductive portion 5022 arranged along a first direction X, as shown in the figure, which is perpendicular to the lamination direction Y. The insulating portion 5021 has both adhesive and insulating properties, and the material of the insulating portion 5021 includes conventional colloids in the art that have insulating and water / oxygen-repellent effects. The conductive portion 5022 is conductive and is made of conductive adhesive or conductive resin, preferably conductive adhesive. The conductive portion 5022 is laminated and connected to the conductive layer 501, and a conductive connection is formed between them.

[0067] Figure 3 for Figure 1 A cross-sectional view of the electrochromic device 1000 along the AA direction. In some embodiments, the electrochromic device 1000 has first conductive connectors 5 on both sides in the stacking direction Y. One side of the first conductive connector 5 is located at the peripheral edge of the first conductive substrate layer 2 and forms an electrical connection with the second conductive substrate layer 4, so as to serve as the positive or negative electrode of the electrochromic device 1000. The other side of the first conductive connector 5 is located at the peripheral edge of the second conductive substrate layer 4 and forms an electrical connection with the first conductive substrate layer 2, so as to serve as the negative or positive electrode of the electrochromic device 1000. The two electrodes are used to electrically connect to an external power source, thereby providing voltage or current to the electrochromic layer. Subsequently, the electrochromic device 1000 can introduce current or voltage to the first conductive base layer 22 of the first conductive substrate layer 2 and the second conductive base layer 42 of the second conductive substrate layer 4 by connecting the conductive components 1 on both sides of the stacking direction Y to an external power source. This forms an electric field on both sides of the electrochromic layer 3, thereby driving the electrochromic layer 3 to undergo coloring or fading. As a result, the electrochromic device 1000 exhibits a change in light transmittance in appearance, thus achieving the function of adjusting the light transmittance of the scene in which the electrochromic device 1000 is applied.

[0068] Specifically, refer to Figure 2The conductive layer 501 can form an electrical connection with the first conductive base layer 22 of the first conductive substrate layer 2 through the conductive portion 5022, and the conductive layer 501 is simultaneously insulated from the second conductive base layer 42 of the second conductive substrate layer 4 through the insulating portion 5021. The conductive layer 501 can also form an electrical connection with the second conductive base layer 42 of the second conductive substrate layer 4 through the conductive portion 5022, and the conductive layer 501 is simultaneously insulated from the first conductive base layer 22 of the first conductive substrate layer 2 through the insulating portion 5021. That is, the insulating portion 5021 is used to isolate the conductive layer 501 from the first conductive base layer 2 or the second conductive base layer 42 of the second conductive substrate layer 4, preventing a short circuit caused by the conductive layer 501 of a single first conductive connector 5 simultaneously forming an electrical connection with both the first conductive substrate layer 2 and the second conductive substrate layer 4, thus ensuring the stability of the electrochromic device 1000.

[0069] Understandably, refer to Figure 2 To achieve good insulation, the insulating portion 5021 simultaneously covers the first conductive substrate layer 2 and the second conductive substrate layer 4 along the first direction. Furthermore, the insulating portion 5021 effectively seals the electrochromic layer 3 on its side in the first direction X, preventing moisture from the external environment from entering the interior of the electrochromic device 1000, thus avoiding damage to the electrochromic material and device failure, and improving product reliability. Therefore, in addition to connecting the electrochromic device 1000 to an external power source, the conductive component 1 also provides a good seal on the side of the electrochromic device 1000, serving a dual purpose; thus eliminating the need for additional sealing adhesive around the periphery of the electrochromic device 1000.

[0070] The electrochromic device of this application has a first conductive connector 5 formed by stacking a conductive layer 501 and an adhesive layer 502. The first conductive connector 5 is bonded to the peripheral edge of the electrochromic device 1000 on any side of the stacking direction by the adhesive layer 502, which is convenient and quick to install. Under the action of the conductive part 5022 and the insulating part 5021, the conductive layer 501 of the first conductive connector 5 on any side can form an electrical connection only with the first conductive base layer 22 of the first conductive base layer 2 or the second conductive base layer 42 of the second conductive base layer 4. This allows the conductive layer 501 to form an electrode on itself or to have an outgoing electrode 8 on it, which facilitates the connection of the electrochromic device 1000 to an external power source.

[0071] Furthermore, the insulating portion 5021 simultaneously covers the first conductive substrate layer 2 and the second conductive substrate layer 4 along the first direction, so that the first conductive connector 5 can also seal the side of the electrochromic layer 3, preventing moisture from the external environment from entering the interior of the electrochromic device 1000 from the side, thus improving product reliability. That is, the conductive component 1 can simultaneously play the dual role of forming the device electrode and sealing the side of the device, thereby eliminating the need to set a sealing colloid on the periphery of the electrochromic device 1000. The ingenious structural design reduces the manufacturing process of the device and improves production efficiency.

[0072] refer to Figures 1-4 In some embodiments, the electrochromic device 1000 has a groove 6 on its peripheral edge, the groove 6 penetrating the first conductive substrate layer 2 and the electrochromic layer 3 along the stacking direction Y, and / or the groove 6 penetrating the second conductive substrate layer 4 and the electrochromic layer 3 along the stacking direction Y; the conductive component 1 is at least partially located in the groove 6, and the two ends of the conductive component 1 in the first direction X are respectively connected to the first conductive substrate layer 2 and the second conductive substrate layer 4.

[0073] Specifically, refer to Figure 1 , Figure 3 , Figure 4 Multiple grooves 6 are alternately arranged at intervals around the periphery of the electrochromic device 1000. Each groove 6 includes a first groove 601 penetrating the first conductive substrate layer 2 and the electrochromic layer 3 along the stacking direction Y; and a second groove 602 penetrating the second conductive substrate layer 4 and the electrochromic layer 3 along the stacking direction Y. The number of first grooves 601 and second grooves 602 is multiple, and can be any number greater than two, depending on the specific circumstances.

[0074] The electrochromic device 1000 has conductive components 1 on both sides in the stacking direction Y. The conductive component 1 on one side is electrically connected to the second conductive base layer 42 in the second conductive substrate layer 4 through multiple first grooves 601. The conductive component 1 on the other side is electrically connected to the first conductive base layer 22 in the first conductive substrate layer 2 through multiple second grooves 602. Thus, a multi-electrode structure can be alternately formed at the peripheral edge of the electrochromic device 1000, thereby accelerating the color-changing speed of the electrochromic device 1000.

[0075] Here, the number and location of the first groove 601 and the second groove 602 are not limited.

[0076] For example, see reference Figure 1 , Figure 2 ,exist Figure 2 From a cross-sectional view, the electrochromic device 1000 has grooves 6 formed at both ends in the first direction X. Alternatively, refer to... Figure 5,exist Figure 5 From a cross-sectional view, the electrochromic device 1000 may have a groove 6 formed at only one end in the first direction X.

[0077] Specifically, the two ends of the conductive component 1 in the first direction X are connected to the first conductive substrate layer 2 and the second conductive substrate layer 4, respectively. Here, the two ends of the conductive component 1 are the two ends of the entire conductive component 1, ensuring that the conductive component 1 can form a seal for the electrochromic layer 3.

[0078] For example, see reference Figure 2 The conductive component 1 may include only the first conductive connector 5. The two ends of the conductive component 1 are the two ends of the first conductive connector 5. The two ends of the first conductive connector 5 are respectively connected to the first conductive substrate layer 2 and the second conductive substrate layer 4, so that the first conductive connector 5 can effectively seal the side of the electrochromic layer 3.

[0079] Or, refer to Figure 7 , Figure 8 , Figure 11 In addition to the first conductive connector 5, the conductive component 1 may also include one or more second conductive connectors 7 arranged sequentially along the first direction X. When the conductive component 1 includes the first conductive connector 5 and the second conductive connectors 7, one end of the conductive component 1 is the end of the first conductive connector 5 close to the electrochromic layer 3, and the other end of the conductive component 1 is the end of the second conductive connector 7 away from the electrochromic layer 3; the conductive component 1 as a whole can effectively seal the side of the electrochromic layer 3.

[0080] In some embodiments, reference Figure 2 , Figure 5 The first conductive connector 5 is connected at both ends in the first direction X to the first conductive substrate layer 2 and the second conductive substrate layer 4, respectively; wherein,

[0081] The conductive portion 5022 of the first conductive connector 5 within the first groove 601 is connected to the peripheral edge of the second conductive substrate layer 4 near the electrochromic layer 3 via the first groove 601, thereby forming an electrical connection between the conductive layer 501 and the second conductive substrate layer 4; and / or,

[0082] The conductive portion 5022 of the first conductive connector 5 in the second groove 602 passes through the second groove 602 and is connected to the peripheral edge of the first conductive substrate layer 2 near the electrochromic layer 3, so that the conductive layer 501 and the first conductive substrate layer 2 form an electrical connection.

[0083] Specifically, when the first conductive connector 5 is installed, the conductive part 5022 needs to be connected to the first conductive base layer 22 of the first conductive base layer 2 or the second conductive base layer 42 of the second conductive base layer 4 to ensure that the conductive layer 501 forms an electrical connection with the first conductive base layer 2 or the second conductive base layer 4 through the conductive part 5022.

[0084] Furthermore, the number of conductive parts 5022 is not limited here. The adhesive layer 502 may have only one conductive part 5022 or multiple conductive parts 5022, as long as the conductive layer 501 can form an electrical connection with the first conductive substrate layer 2 or the second conductive substrate layer 4 through one or more conductive parts 5022.

[0085] In some embodiments, reference Figure 2 , Figure 7 , Figure 8 In the first groove 601, one end of the insulating portion 5021 of the first conductive connector 5 is connected to the peripheral edge of the first conductive substrate 2 away from the electrochromic layer 3, and the other end of the insulating portion 5021 of the first conductive connector 5 is connected to the peripheral edge of the second conductive substrate 4 near the electrochromic layer 3; and / or,

[0086] In the second groove 602, one end of the insulating portion 5021 of the first conductive connector 5 is connected to the peripheral edge of the second conductive substrate 4 away from the electrochromic layer 3, and the other end of the insulating portion 5021 of the first conductive connector 5 is connected to the peripheral edge of the first conductive substrate 2 near the electrochromic layer 3.

[0087] Understandably, in the first groove 601, the insulating portion 5021 can isolate the conductive layer 501 from the first conductive base layer 22 of the first conductive substrate layer 2, so that the conductive layer 501 is only electrically connected to the second conductive base layer 42 of the second conductive substrate layer 4. In the second groove 602, the insulating portion 5021 can isolate the conductive layer 501 from the second conductive base layer 42 of the second conductive substrate layer 4, so that the conductive layer 501 is only electrically connected to the first conductive base layer 22 of the first conductive substrate layer 2; this avoids short circuits caused by mutual contact between the first conductive base layer 22 and the second conductive base layer 42, thereby ensuring the stability of the electrochromic device 1000.

[0088] The insulating part 5021 covers both the first conductive substrate layer 2 and the second conductive substrate layer 4 in both the first groove 601 and the second groove 602. That is, the insulating part 5021 can form a seal on the side of the electrochromic layer 3 in the first direction X, preventing moisture from the external environment from entering the interior of the electrochromic device 1000 from the side, thereby improving the product's service life.

[0089] refer to Figure 5In some embodiments, the adhesive layer 502 of the first conductive connector 5 includes a first conductive portion 5023, a second conductive portion 5024 arranged sequentially, and an insulating portion 5021 connecting the first conductive portion 5023 and the second conductive portion 5024; wherein,

[0090] The conductive layer 501 is electrically connected to the second conductive substrate layer 4 through the second conductive portion 5024, and both ends of the first conductive portion 5023 in the first direction X are disposed on the first conductive substrate layer 2; and / or,

[0091] The conductive layer 501 is electrically connected to the first conductive substrate layer 2 through the second conductive part 5024, and both ends of the first conductive part 5023 in the first direction X are disposed on the second conductive substrate layer 4.

[0092] Specifically, in some embodiments, in the first groove 601, both ends of the second conductive portion 5024 are connected to the peripheral edge of the second conductive substrate layer 4 near the electrochromic layer 3, and both ends of the first conductive portion 5023 are connected to the peripheral edge of the first conductive substrate layer 2 away from the electrochromic layer 3; that is, the conductive layer 501 is electrically connected to the second conductive substrate layer 4 only through the second conductive portion 5024; at this time, the first conductive portion 5023 does not play an electrical connection role, but only plays an adhesive role.

[0093] In other embodiments, in the second groove 602, both ends of the second conductive portion 5024 are connected to the peripheral edge of the first conductive substrate layer 2 near the electrochromic layer 3, and both ends of the first conductive portion 5023 are connected to the peripheral edge of the second conductive substrate layer 4 away from the electrochromic layer 3; that is, the conductive layer 501 is electrically connected to the first conductive substrate layer 2 only through the second conductive portion 5024; at this time, the first conductive portion 5023 does not play an electrical connection role, but only plays an adhesive role.

[0094] In some embodiments, reference Figure 2 In the first groove 601, the first conductive connector 5 partially covers the first conductive substrate layer 2, and the width of the portion of the first conductive connector 5 covering the first conductive substrate layer 2 ranges from 0 to 1 mm. It should be noted that the width of the portion of the first conductive connector 5 covering the first conductive substrate layer 2 is the length of the first conductive connector 5 in the first direction X. By setting the edge of the first conductive connector 5 partially covering the first conductive substrate layer 2, good connectivity between the first conductive connector 5 and the first conductive substrate layer 2 is ensured. This prevents the first conductive connector 5 from separating from or even detaching from the surface of the first conductive substrate layer 2 due to the larger thickness at the peripheral edge of the first conductive substrate layer 2 during the pressing of the electrochromic device 1000.

[0095] In other embodiments, in the second groove 602, the first conductive connector 5 partially covers the second conductive substrate layer 4, and the width of the portion of the first conductive connector 5 covering the second conductive substrate layer 4 ranges from 0 to 1 mm. It should be noted that the width of the portion of the first conductive connector 5 covering the second conductive substrate layer 4 is the length of the first conductive connector 5 in the first direction X. By setting the edge of the first conductive connector 5 to partially cover the second conductive substrate layer 4, good connectivity between the first conductive connector 5 and the second conductive substrate layer 4 is achieved. This prevents the first conductive connector 5 from separating from or even detaching from the surface of the second conductive substrate layer 4 due to the larger thickness at the peripheral edge of the second conductive substrate layer 4 during the pressing of the electrochromic device 1000.

[0096] In some embodiments, the first conductive connector 5 is provided by stacking a conductive layer 501 and an adhesive layer 502. The adhesive layer 502 is pre-formed with conductive adhesive, and then the conductive adhesive is partially removed and filled with insulating adhesive to form an insulating part 5021, which makes the manufacturing process more convenient.

[0097] In other embodiments, the first conductive connector 5 is provided with a conductive layer 501 and an adhesive layer 502 stacked together. The adhesive layer 502 is pre-formed from conductive adhesive, and then an insulating part 5021 is formed by additionally providing insulating adhesive on the conductive adhesive in a localized area.

[0098] Therefore, the first conductive part 5023 and the second conductive part 5024 are respectively formed on both sides of the insulating part 5021, which does not affect the conductivity and sealing function of the first conductive connector 5.

[0099] Please refer to Figure 8-11 In some embodiments, the conductive component 1 further includes at least one second conductive connector 7. Along the first direction X, the first conductive connector 5 and the second conductive connector 7 are sequentially arranged on the peripheral edge of the first conductive substrate layer 2, and the second conductive connector 7 forms an electrical connection with the first conductive substrate layer 2; and / or,

[0100] In other embodiments, the first conductive connector 5 and the second conductive connector 7 are arranged sequentially on the peripheral edge of the second conductive substrate layer 4, and the second conductive connector 7 forms an electrical connection with the second conductive substrate layer 4.

[0101] Understandably, refer to Figure 12The peripheral edge of the electrochromic device 1000 has an irregular structure. At this irregular edge, the first conductive substrate layer 2, the electrochromic layer 3, and the second conductive substrate layer 4 all have irregular shapes. Therefore, when setting the conductive component 1 at this structure, if only one first conductive connector 5 is used for bonding, the width of the first conductive connector 5 needs to be designed to be relatively wide, easily leading to wrinkles in the conductive component 1 during attachment, resulting in unevenness in certain areas of the product. Therefore, when the width of the portion of the peripheral edge of the electrochromic device 1000 to be bonded is the same, by combining the first conductive connector 5 with one or more second conductive connectors 7, the width of both the first conductive connector 5 and the second conductive connector 7 is necessarily smaller than the width when only one first conductive connector 5 is used. The width of the first conductive connector 5 is its length in the first direction X. This makes it easier to attach both the first conductive connector 5 and the second conductive connector 7, reducing the difficulty of operation and making the peripheral edge of the electrochromic device 1000 smoother. Here, the width of the first conductive connector 5 and the width of the second conductive connector 7 are the lengths of the first conductive connector 5 in the first direction X.

[0102] In some embodiments, reference Figure 7 , Figure 8 In the first groove 601, the length of the portion of the second conductive substrate layer 4 extending outward along the first direction X beyond the electrochromic layer 3 ranges from 2 to 10 millimeters. By providing the first conductive connector 5 and the second conductive connector 7 to cover the peripheral edge of the second conductive substrate layer 4, both the first conductive connector 5 and the second conductive connector 7 are easier to attach, preventing wrinkling of either the first conductive connector 5 or the second conductive connector 7, and resulting in a smoother peripheral edge for the electrochromic device 1000.

[0103] In the second groove 602, the length of the portion of the first conductive substrate layer 2 extending outward along the first direction X beyond the electrochromic layer 3 ranges from 2 to 10 millimeters. By providing the first conductive connector 5 and the second conductive connector 7 to cover the peripheral edge of the first conductive substrate layer 2, the first conductive connector 5 and the second conductive connector 7 can be easily attached, preventing wrinkles in either the first conductive connector 5 or the second conductive connector 7, and making the peripheral edge of the first electrochromic device 1000 smoother.

[0104] Specifically, the second conductive connector 7 also has a double-layer structure, comprising a second conductive layer 701 and a second adhesive layer 702 stacked together; and here, the second adhesive layer 702 can be conductive as a whole; or, the second adhesive layer 702 can be partially insulated and partially conductive, so as to satisfy that the second conductive connector 7 can form an electrical connection with the first conductive base layer 2 or the second conductive base layer 4.

[0105] refer to Figure 7 , Figure 8 In some embodiments, the conductive component 1 includes at least partially stacked first conductive connector 5 and second conductive connector 7, with an electrical connection formed between the first conductive connector 5 and the second conductive connector 7; wherein,

[0106] Along the first direction X, the end of the first conductive connector 5 away from the second conductive connector 7 is connected to the peripheral edge of the first conductive substrate 2 on the side away from the electrochromic layer 3, and the end of the second conductive connector 7 away from the first conductive connector 5 is disposed on the peripheral edge of the second conductive substrate 4 on the side close to the electrochromic layer 3; and / or,

[0107] Along the first direction X, the end of the first conductive connector 5 away from the second conductive connector 7 is connected to the peripheral edge of the second conductive substrate 4 away from the electrochromic layer 3, and the end of the second conductive connector 7 away from the first conductive connector 5 is disposed on the peripheral edge of the first conductive substrate 2 close to the electrochromic layer 3.

[0108] In some embodiments, the second adhesive layer 702 of the second conductive connector 7 is entirely composed of conductive adhesive. (Refer to...) Figure 7 , Figure 8 The adjacent first conductive connector 5 and second conductive connector 7 are stacked and connected, so that the first conductive connector 5 and the second conductive connector 7 are electrically connected, making it easier to place the lead electrode 8 on either the first conductive connector 5 or the second conductive connector 7. The stacked connection between the first conductive connector 5 and the second conductive connector 7 also improves the bonding stability of the first conductive connector 5 and the second conductive connector 7.

[0109] Furthermore, the specific stacking arrangement of the first conductive connector 5 and the second conductive connector 7 is not limited here. For example, refer to... Figure 7 One approach is to first install the first conductive connector 5, and then laminate and bond one end of the second conductive connector 7 onto the conductive layer 501 of the first conductive connector 5; or, refer to... Figure 8 Alternatively, the second conductive connector 7 can be set first, and then one end of the first conductive connector 5 can be laminated and bonded to the second conductive connector 7.

[0110] refer to Figure 11 In some embodiments, the conductive component 1 may further include two or more second conductive connectors 7 arranged sequentially, the first conductive connector 5 and the plurality of second conductive connectors 7 being arranged sequentially along the first direction X on the peripheral edge of the electrochromic device 1000, and the first conductive connector 5 and the plurality of second conductive connectors 7 being sequentially stacked and connected.

[0111] Understandably, by providing multiple second conductive connectors 7, the conductive component 1 can be arranged to be longer in the first direction X, forming a larger conductive area, which can accelerate the color-changing speed of the electrochromic device 1000.

[0112] refer to Figure 9 , Figure 10 In some embodiments, adjacent first conductive connectors 5 and second conductive connectors 7 are spaced apart.

[0113] In the first groove 601, the first conductive connector 5 is insulated from the first conductive substrate layer 2 through the insulating portion 5021, and the second conductive connector 7 is electrically connected to the second conductive substrate layer 4; and / or,

[0114] In the second groove 602, the first conductive connector 5 is insulated from the second conductive substrate layer 4 through the insulating part 5021, and the second conductive connector 7 is electrically connected to the first conductive substrate layer 2.

[0115] Specifically, in some embodiments, the first conductive connector 5 may also be spaced apart from the second conductive connector 7, with the second conductive connector 7 forming an electrical connection independently with the first conductive substrate 2 or the second conductive substrate 4. This ensures that the first conductive connector 5 and the second conductive connector 7 do not interfere with each other when connected to the electrochromic device 1000, making it easier to deploy the conductive components 1. (Reference) Figure 11 In some embodiments, the conductive component 1 further includes a seal 9, which is provided between two adjacent first conductive connectors 5 and second conductive connectors 7. And / or,

[0116] The conductive component 1 includes two or more second conductive connectors 7, with adjacent second conductive connectors 7 spaced apart, and a sealing element 9 is provided between adjacent second conductive connectors 7.

[0117] Understandably, when there is a gap between adjacent first conductive connectors 5 and second conductive connectors 7, and between two adjacent second conductive connectors 7, in order to improve the connection stability and sealing of conductive component 1, a sealing member 9 is provided at the gap between adjacent first conductive connectors 5 and second conductive connectors 7, and at the gap between two adjacent second conductive connectors 7, to ensure that the bonding structure of conductive component 1 is stable.

[0118] refer to Figures 7-11 In some embodiments, in the first groove 601, the maximum thickness of the conductive component 1 is less than or equal to the stacking thickness of the first conductive substrate layer 2 and the electrochromic layer 3 in the stacking direction Y; and / or,

[0119] In the second groove 602, the maximum thickness of the conductive component 1 is less than or equal to the stacking thickness of the second conductive substrate layer 4 and the electrochromic layer 3 in the stacking direction Y.

[0120] Specifically, the thickness of the conductive component 1 is the maximum thickness of the entire conductive component 1, which may be only the thickness of the first conductive connector 5; or it may be the maximum stacking thickness of the two stacked first conductive connectors 5 and the second conductive connector 7; or it may be the maximum stacking thickness of the two stacked second conductive connectors 7; there is no limitation here, and the maximum thickness is used as a reference.

[0121] Since the electrochromic device 1000 requires subsequent pressing operations, in the first groove 601, the conductive component 1 as a whole is not higher than the first conductive substrate layer 2 in the stacking direction Y; in the second groove 602, the conductive component 1 as a whole is not higher than the second conductive substrate layer 4 in the stacking direction Y; this ensures that the stress on the conductive component 1 in the first groove 601 or the second groove 602 is not too high, thereby improving structural stability.

[0122] refer to Figure 3 , Figure 6 In some embodiments, outside the first groove 601, both ends of the conductive component 1 along the first direction X are disposed on the first conductive substrate layer 2, and / or, outside the first groove 601, both ends of the conductive component 1 along the first direction X are disposed on the second conductive substrate layer 4.

[0123] Understandably, the electrochromic device 1000 has conductive components 1 surrounding its peripheral edges on both sides in the stacking direction Y. One side of the conductive component 1 is partially located inside the first groove 601 and partially located outside the first groove 601. The two ends of the conductive component 1 located inside the first groove 601 simultaneously cover the first conductive substrate layer 2 and the second conductive substrate layer 4, and the two ends of the conductive component 1 located outside the first groove 601 are both located on the peripheral edge of the first conductive substrate layer 2 away from the electrochromic layer 3. Here, the two ends of the conductive component 1 are the two ends of the entire conductive component 1 in the first direction X.

[0124] On the other side, the conductive component 1 is partially located inside the second groove 602 and partially located outside the second groove 602. The two ends of the conductive component 1 located inside the second groove 602 simultaneously cover the first conductive substrate layer 2 and the second conductive substrate layer 4, and the two ends of the conductive component 1 located outside the second groove 602 are both located on the peripheral edge of the second conductive substrate layer 4 away from the electrochromic layer 3. Here, the two ends of the conductive component 1 are the two ends of the entire conductive component 1 in the first direction X.

[0125] refer to Figures 7-11In some embodiments, it further includes a lead-out electrode 8, which is electrically connected to the second conductive substrate layer 4 via a first conductive connector 5 and / or a second conductive connector 7; and / or,

[0126] The lead electrode 8 is electrically connected to the first conductive substrate layer 2 through the first conductive connector 5 and / or the second conductive connector 7.

[0127] Understandably, by providing lead-out electrodes 8 on the first conductive connector 5 and / or the second conductive connector 7, the electrochromic device 1000 can be easily connected to an external power source.

[0128] In some embodiments, reference Figure 6 , Figure 8 The lead electrode 8 can be disposed only on the conductive layer 501 of the first conductive connector 5. The lead electrode 8 is electrically connected to the first conductive substrate layer 2 through the first conductive connector 5, or the lead electrode 8 is electrically connected to the second conductive substrate layer 4 through the first conductive connector 5.

[0129] In other embodiments, reference is made to... Figure 7 , Figure 8 and Figure 10 Alternatively, the lead electrode 8 can be disposed only on the second conductive layer 701 of the second conductive connector 7. The lead electrode 8 is electrically connected to the first conductive substrate layer 2 through the second conductive connector 7, or the lead electrode 8 is electrically connected to the second conductive substrate layer 4 through the second conductive connector 7.

[0130] In other embodiments, reference is made to... Figure 11 Alternatively, the lead electrode 8 can be disposed only under the second adhesive layer 702 of the second conductive connector 7 to prevent the lead electrode 8 from falling off the first conductive substrate layer 2 or the second conductive substrate layer 4, thereby further improving the stability of the lead electrode 8 connection.

[0131] In yet other embodiments, reference is made to Figure 9 The lead electrode 8 can also cover both the first conductive connector 5 and the second conductive connector 7.

[0132] Understandably, an outgoing electrode 8 is provided on the conductive component 1 on the Y side of the electrochromic device 1000 to form an electrical connection with the second conductive substrate layer 4.

[0133] In other embodiments, lead-out electrodes 8 are provided on the conductive component 1 on the other side of the stacking direction Y of the electrochromic device 1000 to form an electrical connection with the first conductive substrate layer 2.

[0134] In the above embodiment, the lead-out electrodes 8 located on both sides of the electrochromic device in the stacking direction Y are respectively used as the positive or negative electrode of the electrochromic device 1000. The lead-out electrodes 8 on both sides are electrically connected to an external power source, thereby providing voltage to the electrochromic layer. Furthermore, the lead-out electrodes 8 on both sides are always spaced apart in the stacking direction Y to avoid contact between the lead-out electrodes 8, which could cause a short circuit in the electrochromic device 1000, thus improving the stability of the electrochromic device 1000.

[0135] In some embodiments, when the lead electrode 8 is disposed on the first conductive connector 5, the lead electrode 8 is disposed on the side of the conductive layer 501 of the first conductive connector 5 away from the adhesive layer 502, and the lead electrode 8 is electrically connected to the first conductive substrate layer 2 through the conductive portion 5022 of the first conductive connector 5; and / or,

[0136] The lead electrode 8 is disposed on the side of the conductive layer 501 of the first conductive connector 5 away from the adhesive layer 502, and the lead electrode 8 is electrically connected to the second conductive substrate layer 4 through the conductive part 5022 of the first conductive connector 5.

[0137] Understandably, the lead electrode 8 should be placed on the side of the conductive layer 501 away from the adhesive layer 502, and should not be placed on the side of the conductive layer 501 close to the adhesive layer 502, so as to avoid affecting the connection stability between the first conductive connector 5 and the first conductive substrate layer 2 or the second conductive substrate layer 4, and to ensure that the first conductive connector 5 can form an effective seal on the side of the electrochromic layer 3.

[0138] In some embodiments, reference Figure 7 The lead electrode 8 is disposed on at least one side of the second conductive connector 7 in the stacking direction Y; the lead electrode 8 is electrically connected to the first conductive substrate layer 2 through the second conductive connector 7; and / or, the lead electrode 8 is electrically connected to the second conductive substrate layer 4 through the second conductive connector 7.

[0139] In some embodiments, reference Figure 10 In the first groove 601, the lead electrode 8 can be disposed on the side of the second conductive connector 7 away from the second conductive substrate layer 4; and / or, referring to Figure 11 The lead electrode 8 can be disposed on the side of the second conductive connector 7 near the first conductive substrate layer 2.

[0140] In other embodiments, in the second groove 602, the lead-out electrode 8 may be disposed on the side of the second conductive connector 7 away from the first conductive substrate layer 2; and / or, the lead-out electrode 8 may be disposed on the side of the second conductive connector 7 close to the first conductive substrate layer 2.

[0141] Understandably, refer to Figure 10 , Figure 11When a lead-out electrode 8 is separately provided on the second conductive connector 7, since both the second conductive layer 701 and the second adhesive layer 702 of the second conductive connector 7 are conductive, the lead-out electrode 8 can be provided on any side of the second conductive connector 7 in the stacking direction Y, and the electrochromic device 1000 can be powered through the lead-out electrode 8. Furthermore, the second adhesive layer 702 is conductive in its entirety, so providing the lead-out electrode 8 on the second connector 7 results in higher conductivity.

[0142] By adopting the above technical solution, the second adhesive layer 702 of the second conductive connector 7 only has a conductive part. When there is only a conductive part, the larger the area of ​​the conductive part, the smaller the resistance and the higher the conductivity when the lead electrode passes through the second connector 7 due to the larger area of ​​the conductive part.

[0143] refer to Figure 13 The second aspect of this application provides an electrochromic device 2000, including a substrate 2001 disposed on the side of a first conductive substrate 2 away from the electrochromic layer 3; and / or, the substrate 2001 disposed on the side of a second conductive substrate 4 away from the electrochromic layer 3.

[0144] Specifically, the electrochromic device 1000 has substrates 2001 on both sides of the stacking direction Y. The substrates 2001 are bonded to the electrochromic device 1000 on both sides of the stacking direction Y through substrate adhesive layers 2002. The substrates 2001 are transparent and are preferably glass.

[0145] A third aspect of this application provides an electrochromic product, including the electrochromic device 1000 or electrochromic apparatus 2000 described above.

[0146] Electrochromic products include any one of the following: rearview mirrors, curtain walls, car sunroofs, car side windows, car windshields, electronic product housings, eyeglasses, vehicles, and display panels.
