[0073] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0074] Currently, such as Figure 1 As shown, Figure 1 This is a cross-sectional view of a battery. Figure 2 yes Figure 1 The diagram shows a cross-sectional view of the battery at point A-A'. Figure 3 yes Figure 1The diagram shows a cross-sectional view of the battery at point B-B'. The battery may include: a substrate 010, an encapsulating colloid 020, an encapsulating cover 030, a battery body 040, and conductive leads 050. The encapsulating colloid 020 may be annular and may be fixedly connected to the edge portion of the substrate 010. The encapsulating cover 030 may be fixedly connected to the side of the encapsulating colloid 020 opposite to the substrate 010, and the substrate 010, encapsulating colloid 020, and encapsulating cover 030 may form a sealed space S. The battery body 040 may be located within the sealed space S and may be fixedly connected to the substrate 100. Here, the battery body 040 may be used for power generation. The conductive leads 050 may be fixedly connected to the side of the substrate 010 facing the encapsulating cover 030, and a portion of the conductive leads 050 may be located within the sealed space S and electrically connected to the battery body 200, while another portion of the conductive leads 050 may extend through the encapsulating colloid 020 to the outside of the sealed space S. In this way, the conductive lead 050 can output the power generated by the battery body 040 to the electronic device located outside the sealed space S, so as to realize the power transfer from the battery to the electronic device.

[0075] It should be noted that during the battery manufacturing process, the battery body 040 can be fabricated on the substrate 010. After the battery body 040 is fabricated, the edges of the battery body 040 need to be cleaned by a laser edge cleaning process so that a sufficient portion of the edge of the substrate 010 can be exposed for connection of the encapsulating colloid 200.

[0076] However, currently, after cleaning the edges of the battery body 040, some battery body 040 material remains on the exposed edges of the substrate 010. This residual battery body 040 material on the edges of the substrate 010 after the encapsulating colloid 020 connects to the substrate 010 results in poor sealing at the connection point. This allows external moisture to penetrate into the sealed space S through the connection point, leading to encapsulation failure. Furthermore, the current sealing between the conductive lead 050 passing through the encapsulating colloid 020 and the substrate 010 is also poor. External moisture can also penetrate into the sealed space through the connection point between the conductive lead 050 passing through the encapsulating colloid 020 and the substrate 010, further contributing to encapsulation failure.

[0077] This application provides a battery embodiment; please refer to [reference needed]. Figure 4 and Figure 5 , Figure 4 This is a top view of a battery provided in an embodiment of this application. Figure 5 yes Figure 4 The cross-sectional view of the battery shown at C-C' indicates that the battery may include: a substrate 100, a battery body 200, an encapsulation cover 300, and an encapsulation gel 400.

[0078] The substrate 100 in the battery may include a first central portion 101 and a first edge portion 102 surrounding the first central portion 101. The battery body 200 may be located on the first central portion 101 of the substrate 100. The encapsulation cover 300 may be located on the side of the battery body 200 facing away from the substrate 100, and the encapsulation cover 300 may further include a second central portion 301 and a second edge portion 302 surrounding the second central portion 301. The first edge portion 102 in the substrate 100 may be disposed opposite to the second edge portion 302 in the encapsulation cover 300, and the side of the first edge portion 102 in the substrate 100 facing the second edge portion 302 in the encapsulation cover 300 has a first groove H1.

[0079] Here, the first edge portion 102 in the substrate 100 can be the portion of the substrate 100 exposed after the four sides of the battery body 200 are cleaned using a laser edge cleaning process. After the four sides of the battery body 200 are cleaned using a laser edge cleaning process, the substrate 100 can be further etched using a laser to create the first groove H1 in the first edge portion 101 of the substrate 100.

[0080] The encapsulating colloid 400 in the battery can be located between the first edge portion 102 in the substrate 100 and the second edge portion 302 in the encapsulation cover 300. One side of the encapsulating colloid 400 can be connected to the first edge portion 102 within a first groove H1, and the other side of the encapsulating colloid 400 can be connected to the second edge portion 302. The encapsulating colloid 400 can be distributed around the battery body 200. In this way, the battery body 200 can be encapsulated between the substrate 100, the encapsulation cover 300, and the encapsulating colloid 400.

[0081] In this application, the first edge portion 102 of the substrate 100 is the exposed portion of the substrate 100 after the four sides of the battery body 200 are cleaned using a laser edge-cleaning process, and the first groove H1 of the first edge portion 102 is formed by etching the first edge portion 102 of the substrate 100 using a laser. Therefore, the encapsulating colloid 400 can directly contact and connect with the first edge portion 102 within the first groove H1 of the first edge portion 102. In this way, there will be no residual battery body 200 between the substrate 100 and the encapsulating colloid 400, and external moisture will not penetrate through the connection between the encapsulating colloid 400 and the substrate 100 to corrode the battery body 200, resulting in a better battery encapsulation effect.

[0082] In summary, this application provides a battery comprising: a substrate, a battery body, an encapsulation cover, and an encapsulating colloid. Since the first edge portion of the substrate is the exposed portion after the four sides of the battery body are removed using a laser edge-cleaning process, and the first groove of the first edge portion is formed by further etching the first edge portion of the substrate using a laser, the encapsulating colloid can directly contact and connect with the first edge portion within the first groove. This ensures that no battery body residue remains between the substrate and the encapsulating colloid, preventing external moisture from penetrating through the connection point between the encapsulating colloid and the substrate and causing erosion to the battery body, resulting in a better battery encapsulation effect.

[0083] Optional, such as Figure 4 As shown, the first groove H1 of the first edge portion 102 in the substrate 100 can be annular, and the first groove H1 is distributed around the first central portion 101 in the substrate 100. In this way, the side of the encapsulant 400 facing the substrate 100 can be connected to the first edge portion 102 within the first groove H1 of the first edge portion 102, thereby achieving the connection between the encapsulant 400 and the substrate 100. Thus, after the four sides of the battery body 200 are cleaned using a laser edge-cleaning process, a laser can be used to continue etching around the first edge body 102 in the substrate 100, directly etching the annular first groove H1 on the first edge body 102, simplifying the manufacturing process of the first groove H1.

[0084] Optional, such as Figure 4 As shown, the orthographic projection of the encapsulating colloid 400 on the encapsulation cover plate 300 can be located within the orthographic projection of the first groove H1 on the encapsulation cover plate 300. In this way, the side of the encapsulating colloid 400 facing the substrate 100 can all be located within the first groove H1, ensuring that the portion of the encapsulating colloid 400 that connects to the substrate 100 is in direct contact with the substrate 100 within the first groove H1. This further ensures that the encapsulating colloid 400 will not come into contact with any remaining battery body 040, thus further ensuring a better encapsulation effect for the battery.

[0085] It should be noted that, as Figure 6 As shown, Figure 6 yes Figure 4 Another cross-sectional view of the battery at C-C' is shown. In the direction parallel to the substrate 100, the width D1 of the first groove H1 can be greater than or equal to the width D2 of the encapsulating colloid 400. This ensures that the orthographic projection of the encapsulating colloid 400 on the encapsulation cover 300 is located within the orthographic projection of the first groove H1 on the encapsulation cover 300.

[0086] Optional, such as Figure 6 and Figure 7As shown, in the direction parallel to the substrate 100, the width D1 of the first groove H1 can be less than or equal to the width D10 of the first edge portion 102.

[0087] When the width D1 of the first groove H1 is less than the width D10 of the first edge portion 102, such as Figure 6 As shown, the orthographic projection of the first groove H1 onto the first edge portion 102 is located within the first edge portion 102. After the four sides of the battery body 200 are cleaned using a laser edge-cleaning process to expose the first edge portion 102, a portion of the first edge portion 102 can be etched away using a laser to form the first groove H1.

[0088] When the width D1 of the first groove H1 is equal to the width D10 of the first edge portion 102, such as Figure 7 As shown, Figure 7 yes Figure 4 The diagram shows another cross-sectional view of the battery at point C-C'. The first central portion 101 of the substrate 100, facing away from the encapsulation cover 300, can be flush with the side of the first edge portion 102 facing away from the encapsulation cover 300. In the direction perpendicular to the substrate 100, the thickness D4 of the first central portion 101 can be greater than the thickness D3 of the first edge portion 102. Here, after the four sides of the battery body 200 are cleaned using a laser edge-cleaning process, the edges of the substrate 100 can be further etched using a laser to gradually reduce the thickness D3 of the first edge portion 102 in the substrate 100 until the thickness D3 of the first edge portion 102 is less than the thickness D4 of the first central portion 101.

[0089] It should be noted that while the thickness D3 of the first edge portion 102 of the substrate 100 is gradually reduced by etching with a laser, the remaining portion of the battery body 200 located on the first edge portion 102 is also etched away. Therefore, in one possible case, such as Figure 7 As shown, the side of the encapsulating colloid 400 facing the substrate 100 can be directly connected to the first edge portion 102. That is, the portion of the first edge portion 102 that is recessed relative to the first central portion 101 in the direction facing the substrate 100 away from the encapsulation cover plate 300 is the first groove H1.

[0090] Of course, in another possible case, when the width D1 of the first groove H1 is equal to the width D10 of the first edge portion 102, such as Figure 8 As shown, Figure 8 yes Figure 4Another cross-sectional view of the battery at C-C' is shown. The first edge portion 102 may also have an auxiliary groove H3 communicating with the first groove H1. The side of the encapsulant 400 facing the substrate 100 may be connected to the first edge portion 102 within the auxiliary groove H3. Here, in the direction parallel to the substrate 100, the width D11 of the third groove H3 may be smaller than the width D10 of the first edge portion 102.

[0091] Here, after the thickness D3 of the first edge portion 102 of the substrate 100 is reduced by etching with a laser, an auxiliary groove H3 can be etched on the first edge portion 102 by a laser. The side of the encapsulant 400 facing the substrate 100 can be connected to the first edge portion 102 in the auxiliary groove H3.

[0092] Optional, such as Figure 9 and Figure 10 As shown, Figure 9 This is a top view of another battery provided in an embodiment of this application. Figure 10 yes Figure 9 The diagram shows a cross-sectional view of the battery at E-E'. Figure 11 yes Figure 9 The diagram shows a cross-sectional view of the battery at point F-F'. The substrate 100, encapsulating gel 400, and encapsulating cover 300 in the battery can be used to enclose a sealed space S. The battery body 200 in the battery can be located within the sealed space S.

[0093] The battery may further include conductive leads 500. A portion of the conductive leads 500 may be located on the side of the first central portion 101 of the substrate 100 facing the encapsulation cover 300 and may be electrically connected to the battery body 200. Another portion of the conductive leads 500 may extend through the encapsulation colloid 400 to the outside of the sealed space S. In this way, the conductive leads 500 can output the power generated by the battery body 200 to an electronic device located outside the sealed space S, thereby realizing the power transfer from the battery to the electronic device.

[0094] Optional, such as Figure 11 As shown, the battery may further include an insulating pad 600. The insulating pad 600 in the battery can be fixedly connected to the first edge portion 102 within a first groove H1 of the first edge portion 102. The orthographic projection of the insulating pad 102 in the battery onto the encapsulation cover 300 may overlap with the orthographic projection of the portion of the conductive lead 500 passing through the encapsulation colloid 400 onto the encapsulation cover 300. Furthermore, in a direction perpendicular to the substrate 100, the portion of the conductive lead 500 passing through the encapsulation colloid 400 may be located between the insulating pad 600 and the encapsulation colloid 400.

[0095] In this way, the portion of the conductive lead 500 that passes through the encapsulating colloid 400 can be connected to the substrate 100 through the insulating gasket 600, and the insulating gasket 600 can prevent moisture from entering the sealed space S through the gap between the conductive lead 500 and the substrate 100. By providing the insulating gasket 600 between the portion of the conductive lead 500 that passes through the encapsulating colloid 400 and the substrate 100, the sealing of the connection between the portion of the conductive lead 500 that passes through the encapsulating colloid 400 and the substrate 100 can be ensured, thereby further guaranteeing the battery encapsulation effect.

[0096] It should be noted that in subsequent embodiments, such as Figure 16 As shown, the battery body 200 may include: a first electrode layer 201, a hole transport layer 202, a perovskite layer 203, an electron transport layer 204, and a second electrode layer 205 stacked along a direction away from the substrate 100. The orthographic projections of the hole transport layer 202, the perovskite layer 203, the electron transport layer 204, and the second electrode layer 205 on the encapsulation cover plate 300 can all be located within the orthographic projection of the first electrode layer 201 on the encapsulation cover plate 300, and the outer edges of the orthographic projections of the hole transport layer 202, the perovskite layer 203, the electron transport layer 204, and the second electrode layer 205 on the encapsulation cover plate 300 do not coincide with the orthographic projection of the first electrode layer 201 on the encapsulation cover plate 300.

[0097] Here, after using a laser edge-cleaning process to remove the four sides of the battery body 200 to expose the edges of the substrate 100, a semi-edge-cleaning process can be performed on the battery body 200 using a laser to remove the hole transport layer 202, perovskite layer 203, electron transport layer 204, and second electrode layer 205, exposing the edge portion of the first electrode layer 201. The portion of the conductive lead 500 located within the accommodating space S can be positioned on the side of the edge portion of the first electrode layer 201 facing away from the substrate 100, thereby achieving electrical connection between the conductive lead 500 and the electrode body 200. The portion of the conductive lead 500 passing through the encapsulating colloid 400 can be fixed to the side of the substrate 100 facing the encapsulation cover 300 using an insulating gasket 600.

[0098] Optional, such as Figure 11 and Figure 12 As shown, Figure 12 yes Figure 9 The diagram shows a cross-sectional view of the battery at G-G'. In the direction perpendicular to the substrate 100, the thickness D5 of the insulating pad 600 in the battery can be greater than or equal to the groove depth D6 of the first groove H1 of the first edge portion 102. For example, the groove depth D6 of the first groove H1 can be greater than 10 nanometers.

[0099] The portion of the conductive lead 500 that passes through the encapsulating colloid 400 can abut against the insulating pad 600. Here, the thickness D5 of the insulating pad 600 is greater than or equal to the groove depth D6 of the first groove H1, so that the side of the insulating pad 600 located in the first groove H1 that faces away from the substrate 100 can abut against the portion of the conductive lead 500 that passes through the encapsulating colloid 400, thereby allowing the portion of the conductive lead 500 that passes through the encapsulating colloid 400 to be connected to the substrate 100 through the insulating pad 600.

[0100] It should be noted that the conductive lead 500 in the battery can be conductive tape, solder ribbon, or copper tape, etc. The portion of the conductive lead 500 that passes through the encapsulating colloid 400 can be fixedly connected to the side of the insulating pad 600 located in the first groove H1 away from the substrate 100 by pressure-sensitive adhesive.

[0101] Optional, such as Figure 13 As shown, Figure 13 yes Figure 9 A partially enlarged view of the battery is shown. In a first direction X, perpendicular to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D7 of the insulating pad 600 may be greater than or equal to the width D8 of the conductive lead 500.

[0102] like Figure 6 and Figure 13 As shown, in the direction parallel to the substrate 100, the width D1 of the first groove H1 can be greater than or equal to the width D2 of the encapsulating colloid 400. This means that in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D1 of the first groove H1 can be greater than or equal to the width D2 of the encapsulating colloid 400. Here, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width of the portion of the conductive lead 500 that passes through the encapsulating colloid 400 is the width D2 of the encapsulating colloid 400.

[0103] It should be noted that, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the length D9 of the insulating pad 600 can be greater than or equal to the width D2 of the encapsulating colloid 400. Thus, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width of the portion of the conductive lead 500 passing through the encapsulating colloid 400 can be less than or equal to the length D9 of the insulating pad 600.

[0104] Thus, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width of the portion of the conductive lead 500 passing through the encapsulating colloid 400 can be less than or equal to the length D9 of the insulating pad 600, and in the first direction X perpendicular to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D8 of the conductive lead 500 can also be less than or equal to the width D7 of the insulating pad 600.

[0105] It should be noted that, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D1 of the first groove H1 can be greater than the width D9 of the insulating pad 600 plus 0.2 mm, and the width D2 of the insulating pad 600 can be greater than the width of the encapsulating colloid 400 plus 0.2 mm. This ensures that the insulating pad 600 can be completely adhered within the first groove H1, guaranteeing the connection strength between the insulating pad 600 and the first edge portion 102.

[0106] In this way, the orthographic projection of the portion of the conductive lead 500 passing through the encapsulating colloid 400 on the encapsulation cover 300 can lie within the orthographic projection of the insulating gasket 600 on the encapsulation cover 300. Thus, the portion of the conductive lead 500 passing through the encapsulating colloid 400 can be connected to the substrate 100 through the insulating gasket 600, further ensuring that external moisture will not penetrate into the sealed space S through the portion of the conductive lead 500 passing through the encapsulating colloid 400 and the substrate 100, causing corrosion to the battery body 200.

[0107] Optional, such as Figure 13 As shown, the orthographic projection of the insulating pad 600 in the battery onto the encapsulation cover 300 can lie within the orthographic projection of the first edge portion 102 onto the encapsulation cover 300. Here, since the orthographic projection of the insulating pad 600 onto the encapsulation cover 300 is located within the first groove H1 of the first edge portion 102, the orthographic projection of the insulating pad 600 onto the encapsulation cover 300 can lie within the orthographic projection of the first edge portion 102 onto the encapsulation cover 300.

[0108] Optionally, the insulating gasket 600 in the battery can be made of a water- and oxygen-resistant material. In this way, the insulating gasket 600 can completely block moisture from entering through the connection between the portion of the conductive lead 500 that passes through the encapsulating colloid 400 and the substrate 100, making the moisture-blocking effect of the insulating gasket 600 more significant, thereby further improving the encapsulation effect of the battery.

[0109] Optional, such as Figure 14 As shown, Figure 14This is a cross-sectional view of a battery provided in an embodiment of this application. The first edge portion 102 may have multiple first grooves H1, and the multiple first grooves H1 may be nested sequentially. The battery may include multiple encapsulating colloids 400, and the multiple encapsulating colloids 400 may correspond one-to-one with the multiple first grooves H1. The portion of the encapsulating colloid 400 within the corresponding first groove H1 may be connected to the first edge portion 102. By encapsulating the battery body 200 with multiple encapsulating colloids 400, the encapsulation effect of the battery can be further improved. It should be noted that in any two adjacent encapsulating colloids 400, these two encapsulating colloids 400 may be connected together or distributed separately; this embodiment of the application does not specifically limit this.

[0110] Optional, such as Figure 15 As shown, Figure 15 This is a top view of another battery provided in the embodiments of this application. The battery may include two conductive leads 500, which may be a first conductive lead 501 and a second conductive lead 502, respectively.

[0111] The battery body 200 may include a plurality of sub-cell cells 200a arranged sequentially in a first direction X. The first direction X may be perpendicular to the extension direction of the conductive lead 500 and parallel to the substrate 100. Each sub-cell cell 200a in the battery body 200 may have a first electrode V1 and a second electrode V2. For any two adjacent sub-cell cells 200a, the first electrode V1 of one sub-cell cell 200a may be electrically connected to the second electrode V2 of the other sub-cell cell 200a. This allows for the series connection of multiple sub-cell cells 200a in the battery body 200.

[0112] Furthermore, the two outermost sub-battery units 200a located in the first direction X can be respectively the first sub-battery unit 200a1 and the second sub-battery unit 200a2. The first conductive lead 501 in the battery can be electrically connected to the first terminal V1 of the first sub-battery unit 200a1, and the second conductive lead 502 in the battery can be electrically connected to the second terminal V2 of the second sub-battery unit 200a2. The multiple sub-battery units 200a connected in series can be connected to the positive and negative terminals of the electronic device through the first terminal V1 of the first sub-battery unit 200a1 and the second terminal V2 of the second sub-battery unit 200a2, thereby enabling the multiple sub-battery units 200a connected in series to supply power to the electronic device.

[0113] It should be noted that the cross-sectional views in the following embodiments are illustrative, taking the battery body 200 including three sub-battery units 200a as an example.

[0114] Optional, such as Figure 16As shown, Figure 16 yes Figure 15 The diagram shows a cross-sectional view of the battery at point K-K'. The battery body 200 may include a first electrode layer 201, a hole transport layer 202, a perovskite layer 203, an electron transport layer 204, and a second electrode layer 205 stacked along a direction away from the substrate 100. Here, the battery having the perovskite layer 203 can be a solar cell. When sunlight shines on the perovskite layer 203, solar energy can be converted into electrical energy through the perovskite layer 203, the hole transport layer, and the electron transport layer 204, and then the electrical energy can be transmitted out through the first electrode layer 201 and the second electrode layer 205.

[0115] like Figure 15 As shown, the battery body 200 may have multiple effective power generation regions O distributed in the first direction X, and a first ineffective region U1 located between two adjacent effective power generation regions O. The sub-battery unit 200a in the battery body 200 may be the portion of the battery body 200 located within the effective power generation region O. The portion of the battery body 200 located within the first ineffective region U1 is the first auxiliary unit 200b1.

[0116] like Figure 16 and Figure 17 As shown, Figure 17 yes Figure 15 Another cross-sectional view of the battery at K-K' is shown. The first electrode layer 201 in the battery body 200 may include a plurality of first electrode strips 2011 spaced apart in the first direction X. The second electrode layer 205 in the battery body 200 may include a plurality of second electrode strips 2051 spaced apart in the first direction X.

[0117] Among them, for any one of the multiple first electrode strips 2011 distributed in the middle, the part of the first electrode strip 2011 located in the effective power generation area O can be the first electrode V1 of the sub-battery unit 200a, and the part of the first electrode strip 2011 located in the first ineffective area U1 can be the first transfer electrode V3 of the first auxiliary unit 200b1.

[0118] For any one of the multiple second electrode strips 2051 except the one closest to the second conductive lead 502, the portion of that second electrode strip 2051 located within the effective power generation region O can be the second transfer electrode V4 of the first auxiliary unit 200b1. Here, the first transfer electrode V3 and the second transfer electrode V4 in the same first auxiliary unit 200b1 are connected. Thus, for any two adjacent sub-cell cells 200a, through the electrical connection of the first transfer electrode V3 and the second transfer electrode V4 in the first auxiliary unit 200b1 located between the two adjacent sub-cell cells 200a, the first electrode of one sub-cell cell 200a and the second electrode of the other sub-cell cell 200a can be electrically connected, thereby realizing the series connection of the two sub-cell cells 200a.

[0119] For the first electrode strip 2011 closest to the first conductive lead 501 among a plurality of first electrode strips 2011, the portion of the first electrode strip 2011 located in the effective power generation region O can be the first electrode V1 of the first sub-cell 200a1, and the other portions V5 of the first electrode strip 2011 can be used for electrical connection with the first conductive lead 501. This achieves electrical connection between the first electrode V1 of the first sub-cell 200a1 and the first conductive lead 501.

[0120] It should be noted that the portion of the first conductive lead 501 located within the first central region 101 of the substrate 100 can be disposed on the side of the other portion V5 of the first electrode strip 2011 closest to the first conductive lead 501 facing away from the substrate 100 and electrically connected.

[0121] For the first electrode strip 2011 closest to the second conductive lead 502 among the multiple first electrode strips 2011, a portion V6 of the first electrode strip 2011 is used to connect to the second electrode V2 of the second sub-cell 200a2, and another portion V7 of the first electrode strip 2011 is used to connect to the second conductive lead 502. This achieves the electrical connection between the second electrode V2 of the second sub-cell 200a2 and the second conductive lead 502.

[0122] It should be noted that the portion of the second conductive lead 502 located within the first central region 101 of the substrate 100 can be disposed on the side of the first electrode strip 2011 closest to the second conductive lead 502 that is opposite to the substrate 100 and electrically connected.

[0123] Optional, such as Figure 16 , Figure 17 and Figure 18 As shown, Figure 18 yes Figure 16The diagram shows a partially enlarged cross-sectional view of the battery at point K-K'. The first invalid region U1 in the battery body 200 can be divided along the first direction X into a first sub-region U11, a second sub-region U12, and a third sub-region U13 arranged at intervals. The first sub-region U11 can be the area between two adjacent first electrode strips 2021, and the third sub-region U13 can be the area between two adjacent second electrode strips 2051. The second sub-region U12 can be located between the first sub-region U11 and the third sub-region U13.

[0124] The first auxiliary unit 200b1 may have a first through-slot J1 distributed within the second sub-region U12 and a second through-slot J2 distributed within the third sub-region U13. Both the first through-slot J1 and the second through-slot J2 can penetrate the hole transport layer 202, the perovskite layer 203, and the electron transport layer 204. Here, the first through-slot J1 is filled with conductive portions. The conductive portions located within the first through-slot J1 can be formed simultaneously with the second electrode layer 205 and are made of the same material. In the same first auxiliary unit 200b1, the second transfer electrode V4 can be electrically connected to the first transfer electrode V3 through the conductive portions located within the first through-slot J1.

[0125] like Figure 16 and Figure 17 As shown, the battery body 200 may also have a second ineffective region U2 arranged adjacent to the effective power generation region O in the first direction X. The portion of the battery body 200 located within the second ineffective region U2 may be a second auxiliary unit 200b2, and the second auxiliary unit 200b2 may be located between the second sub-battery unit 200a1 and the second conductive lead 502.

[0126] Among them, the second electrode strip 2051 closest to the second conductive lead 502 among the multiple second electrode strips 2051 can be the second electrode V2 of the second sub-cell 200a2 if the part of the second electrode strip 2051 is located in the effective power generation region O, and the part of the second electrode strip 2051 located in the second ineffective region U2 can be the third transfer electrode V8 in the second auxiliary unit 200b2.

[0127] like Figure 16 and Figure 17 As shown, for the first electrode strip 2011 closest to the second conductive lead 502 among a plurality of first electrode strips 2011, the portion of this first electrode strip 2011 located within the second ineffective region U2 can be the fourth transfer electrode V6 in the second auxiliary unit 200b2, and the other portion V7 of this first electrode strip 2011 can be used for electrical connection with the second conductive lead 502. Here, the third transfer electrode V8 in the second auxiliary unit 200b2 can be connected to the fourth transfer electrode V6.

[0128] In this way, the second electrode V2 of the second sub-cell 200a2 is electrically connected to the fourth electrode V6 of the second auxiliary electrode 200b2 through the third transfer electrode V8 in the second auxiliary unit 200b2, and then electrically connected to the second conductive lead 502 through the other part V7 in the first electrode strip 2011.

[0129] like Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, Figure 19 yes Figure 16 Another enlarged view of the cross-sectional view of the battery at K-K' shows that the second invalid region U2 in the battery body 200 can be divided into a fourth sub-region U21 and a fifth sub-region U22 arranged at intervals in the first direction X. The fourth sub-region U21 in the second invalid region U2 can be the area between two adjacent first electrode strips 2011 that are closest to the second conductive lead 502 among the plurality of first electrode strips 2011. The fifth sub-region U22 in the second invalid region U2 can be located between the fourth sub-region U21 and the second conductive lead 502.

[0130] The second auxiliary unit 200b2 may have a third through-slot J3 distributed within the fifth sub-region U22, which penetrates the hole transport layer 202, the perovskite layer 203, and the electron transport layer 204. Here, the third through-slot J3 is filled with a conductive portion. The conductive portion located within the third through-slot J3 may be formed simultaneously with the second electrode layer 205 and made of the same material. In the second auxiliary unit 200b2, the third transfer electrode V8 may be electrically connected to the fourth transfer electrode V6. This enables the electrical connection between the second electrode layer 205 of the second sub-cell unit 200a2 and the second conductive lead 502.

[0131] In summary, this application provides a battery comprising: a substrate, a battery body, an encapsulation cover, and an encapsulating colloid. Since the first edge portion of the substrate is the exposed portion after the four sides of the battery body are removed using a laser edge-cleaning process, and the first groove of the first edge portion is formed by further etching the first edge portion of the substrate using a laser, the encapsulating colloid can directly contact and connect with the first edge portion within the first groove. This ensures that no battery body residue remains between the substrate and the encapsulating colloid, preventing external moisture from penetrating through the connection point between the encapsulating colloid and the substrate and causing erosion to the battery body, resulting in a better battery encapsulation effect.

[0132] This application also provides a battery, such as... Figure 20 , Figure 21 and Figure 22 As shown, Figure 20This is a top view of another battery provided in an embodiment of this application. Figure 21 yes Figure 20 The diagram shows a cross-sectional view of the battery at point I-I'. Figure 22 yes Figure 20 The diagram shows a cross-sectional view of the battery at L-L'. The battery may include: a substrate 100, a battery body 200, an encapsulation cover 300, an encapsulation gel 400, conductive leads 500, and an insulating pad 600.

[0133] The substrate 100 in the battery may include a first central portion 101 and a first edge portion 102 surrounding the first central portion 101. The battery body 200 may be located on the first central portion 101 of the substrate 100. The encapsulation cover 300 may be located on the side of the battery body 200 opposite to the substrate 100, and the encapsulation cover 300 may further include a second central portion 301 and a second edge portion 302 surrounding the second central portion 301. The first edge portion 102 in the substrate 100 may be disposed opposite to the second edge portion 302 in the encapsulation cover 300.

[0134] The encapsulating colloid 400 in the battery can be located between the first edge portion 102 of the substrate 100 and the second edge portion 302 of the encapsulation cover 300. The encapsulating colloid 400 can be distributed around the battery body 200. The substrate 100, encapsulating colloid 400, and encapsulation cover 300 in the battery can be used to form a sealed space S. The battery body 200 in the battery can be located within the sealed space S.

[0135] A portion of the conductive leads 500 may be located on the side of the first central portion 101 of the substrate 100 facing the encapsulation cover 300, and may be electrically connected to the battery body 200. Another portion of the conductive leads 500 may extend through the encapsulation colloid 400 to the outside of the sealed space S. In this way, the conductive leads 500 can output the power generated by the battery body 200 to an electronic device located outside the sealed space S, thereby realizing the power transfer from the battery to the electronic device.

[0136] The insulating pad 600 in the battery can be fixedly connected to the first edge portion 102. The orthographic projection of the insulating pad 102 in the battery onto the encapsulation cover 300 can overlap with the orthographic projection of the portion of the conductive lead 500 passing through the encapsulation colloid 400 onto the encapsulation cover 300. Furthermore, in the direction perpendicular to the substrate 100, the portion of the conductive lead 500 passing through the encapsulation colloid 400 can be located between the insulating pad 600 and the encapsulation colloid 400.

[0137] In this way, the portion of the conductive lead 500 that passes through the encapsulating colloid 400 can be connected to the substrate 100 through the insulating gasket 600, and the insulating gasket 600 can prevent moisture from entering the sealed space S through the gap between the conductive lead 500 and the substrate 100. By providing the insulating gasket 600 between the portion of the conductive lead 500 that passes through the encapsulating colloid 400 and the substrate 100, the sealing of the connection between the portion of the conductive lead 500 that passes through the encapsulating colloid 400 and the substrate 100 can be guaranteed, thereby ensuring the encapsulation effect of the battery.

[0138] Optional, such as Figure 19 As shown, in a first direction X perpendicular to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D7 of the insulating pad 600 can be greater than or equal to the width D8 of the conductive lead 500.

[0139] It should be noted that, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the length D9 of the insulating pad 600 can be greater than or equal to the width D2 of the encapsulating colloid 400. Thus, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width of the portion of the conductive lead 500 passing through the encapsulating colloid 400 can be less than or equal to the length D9 of the insulating pad 600.

[0140] Thus, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width of the portion of the conductive lead 500 passing through the encapsulating colloid 400 can be less than or equal to the length D9 of the insulating pad 600, and in the first direction X perpendicular to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D8 of the conductive lead 500 can also be less than or equal to the width D7 of the insulating pad 600.

[0141] In this way, the orthographic projection of the portion of the conductive lead 500 passing through the encapsulating colloid 400 on the encapsulation cover 300 can lie within the orthographic projection of the insulating gasket 600 on the encapsulation cover 300. Thus, the portion of the conductive lead 500 passing through the encapsulating colloid 400 can be connected to the substrate 100 through the insulating gasket 600, further ensuring that external moisture will not penetrate into the sealed space S through the portion of the conductive lead 500 passing through the encapsulating colloid 400 and the substrate 100, causing corrosion to the battery body 200.

[0142] In summary, this application also provides a battery, including: a substrate, a battery body, an encapsulation cover, an encapsulating colloid, conductive leads, and an insulating gasket. The portion of the conductive lead passing through the encapsulating colloid can be connected to the substrate via the insulating gasket, and the insulating gasket can prevent moisture from entering the sealed space through the gap between the conductive lead and the substrate. Thus, by providing an insulating gasket between the portion of the conductive lead passing through the encapsulating colloid and the substrate, the sealing of the connection between the portion of the conductive lead passing through the encapsulating colloid and the substrate can be ensured, thereby guaranteeing the battery's encapsulation effect.

[0143] Optional, such as Figure 23 , Figure 24 and Figure 25 As shown, Figure 23 This is a top view of a battery provided in another embodiment of this application. Figure 24 yes Figure 23 The diagram shows a cross-sectional view of the battery at N-N'. Figure 25 yes Figure 23 The diagram shows a cross-sectional view of the battery at Q-Q'. The first edge portion 102 of the substrate 100, facing the encapsulation cover 300, may have a second groove H2. The shape of the second groove H2 may match the shape of the insulating pad 600, and the insulating pad 600 may be fixedly connected to the first edge portion 102 within the second groove H2. Thus, in a direction perpendicular to the substrate 100, a portion of the insulating pad 600 is located within the second groove H2, reducing the overall thickness of the substrate 100 and the insulating pad 600, and consequently reducing the overall thickness of the battery.

[0144] Here, "the shape of the second groove H2 can match the shape of the insulating gasket 600" means that the shape of the orthographic projection of the second groove H2 on the encapsulation cover 300 is similar to the shape of the orthographic projection of the insulating gasket 600 on the encapsulation cover 300. For example, when the orthographic projection of the insulating gasket 600 on the encapsulation cover 300 is rectangular, the orthographic projection of the second groove H2 on the encapsulation cover 300 is also rectangular.

[0145] Optional, such as Figure 23 , Figure 24 and Figure 25 As shown. In the direction perpendicular to the substrate 100, the thickness D5 of the insulating pad 600 in the battery can be greater than or equal to the groove depth D6 of the second groove H2 of the first edge portion 102. For example, the groove depth D6 of the second groove H2 can be greater than 10 nanometers.

[0146] Here, the thickness D5 of the insulating pad 600 is greater than or equal to the groove depth D6 of the first groove H, which allows the side of the insulating pad 600 located in the first groove H1 that faces away from the substrate 100 to abut against the portion of the conductive lead 500 that passes through the encapsulating colloid 400, thereby allowing the portion of the conductive lead 500 that passes through the encapsulating colloid 400 to be connected to the substrate 100 through the insulating pad 600.

[0147] Optional, such as Figure 23 , Figure 24 and Figure 25 As shown, in the direction parallel to the substrate 100, the width D1 of the second groove H2 can be greater than or equal to the width D2 of the encapsulating colloid 400. This means that in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D1 of the second groove H2 can be greater than or equal to the width D2 of the encapsulating colloid 400.

[0148] It should be noted that, in the direction parallel to the extension direction of the conductive lead 500 and parallel to the substrate 100, the width D1 of the second groove H2 can be greater than the width D9 of the insulating pad 600 plus 0.2 mm, and the width D2 of the insulating pad 600 can be greater than the width of the encapsulating colloid 400 plus 0.2 mm. This ensures that the insulating pad 600 can be completely adhered within the second groove H2, guaranteeing the connection strength between the insulating pad 600 and the first edge portion 102.

[0149] Optionally, the insulating gasket 600 in the battery can be made of a water- and oxygen-resistant material. In this way, the insulating gasket 600 can completely block moisture from entering through the connection between the portion of the conductive lead 500 that passes through the encapsulating colloid 400 and the substrate 100, making the moisture-blocking effect of the insulating gasket 600 more significant, thereby further improving the encapsulation effect of the battery.

[0150] In summary, this application also provides a battery, including: a substrate, a battery body, an encapsulation cover, an encapsulating colloid, conductive leads, and an insulating gasket. The portion of the conductive lead passing through the encapsulating colloid can be connected to the substrate via the insulating gasket, and the insulating gasket can prevent moisture from entering the sealed space through the gap between the conductive lead and the substrate. Thus, by providing an insulating gasket between the portion of the conductive lead passing through the encapsulating colloid and the substrate, the sealing of the connection between the portion of the conductive lead passing through the encapsulating colloid and the substrate can be ensured, thereby guaranteeing the battery's encapsulation effect.
