Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0035] In related art, a battery consists of a housing 100 and a battery cell. Housing 100 is the outer layer of the battery, protecting the internal battery cell and other components. The battery cell is the core of the battery and the unit that stores and releases electrical energy. It is composed of key materials such as the positive electrode, negative electrode, separator, and electrolyte, and converts chemical energy into electrical energy through chemical reactions.

[0036] The battery cell is usually arranged inside the shell 100, and the battery cell includes a positive electrode ear and a negative electrode ear. In some cases, the negative electrode ear of the battery cell is directly connected to the shell 100, thereby making the shell 100 negatively charged. After the shell 100 is negatively charged, the positive electrode ear needs to be insulated from the shell 100. Specifically, the battery includes a pole, the pole and the shell 100 are insulated, and the pole and the positive electrode ear are connected. The specific method of insulating the pole and the shell 100 is that an insulating sheet is arranged between the pole and the shell 100 inside the shell 100 to achieve insulation between the pole and the inside of the shell 100, and an insulating sheet is arranged between the pole and the shell 100 outside the shell 100 to achieve insulation between the pole and the outside of the shell 100. Among them, inside the shell 100, after the insulating sheet is arranged between the pole and the shell 100, the insulating sheet will occupy a certain space inside the shell 100, which will result in a smaller size of the battery cell, thereby making the energy density of the battery lower. To this end, the present application proposes a battery.

[0037] Please refer to Figures 1 to 4In some embodiments, a battery includes a housing 100, a battery cell, a connector 200, and an insulating member 300. The housing 100 has a storage cavity 110 and a first through-hole 120 connected to each other. The storage cavity 110 can be used to store the battery cell. The first through-hole 120 is for the connector 200 to pass through, thereby electrically connecting to the first tab. The battery cell is disposed in the storage cavity 110 and includes a first tab and a second tab. The first tab can be a positive or negative tab. The second tab can be a positive or negative tab. The first tab is connected to the connector 200 to enable charging and discharging of the battery cell. The second tab can be directly connected to the housing 100, thereby charging the housing 100 with a positive or negative charge. The connector 200 is made of a conductive material. Conductive materials are materials used to transport and conduct electric current. Conductive materials are mainly divided into two categories: good conductors and high-resistance materials. In practical applications, common conductive materials include metals, conductive plastics, and conductive rubber. The metal conductive material can be copper, aluminum, etc., which has good electrical conductivity and mechanical strength. The connector 200 includes a first main body 210 and a first protrusion 220. The first main body 210 is connected to the first protrusion 220, and the first protrusion 220 protrudes relative to the first main body 210. The connector 200 can be in a "T" shape. The first protrusion 220 is arranged in the first through hole 120. The first protrusion 220 is arranged in the first through hole 120. Specifically, it means that the first protrusion 220 and the hole wall of the first through hole 120 are insulated, for example, there is a gap between the first protrusion 220 and the hole wall of the first through hole 120, or there is an insulating material between the first protrusion 220 and the hole wall of the first through hole 120. The first protrusion 220 is electrically connected to the first pole lug. After the first protrusion 220 is electrically connected to the first pole lug, the current on the first pole lug can flow to the connector 200. The two sides of the insulating member 300 are respectively connected to the first body portion 210 and the shell 100, so that the insulating member 300 insulates the first body portion 210 and the shell 100, effectively avoiding the situation where the shell 100 and the first body portion 210 contact and short-circuit. Specifically, the insulating member 300 is arranged between the first body portion 210 and the shell 100, which can achieve insulation between the first body portion 210 and the shell 100. The first protrusion 220 is arranged in the first through-hole 120 and electrically connected to the first tab, which can realize charging and discharging of the battery cell with the outside world through the connector 200. In the prior art, after the first tab and the pole are connected, an insulating sheet needs to be arranged between the pole and the shell 100 for insulation, which will result in a lower energy density of the battery. In the present application, the setting of the insulating sheet is omitted, thereby improving the energy density of the battery. Specifically, the battery can have a higher energy density.

[0038] Furthermore, the first tab is directly electrically connected to the first protrusion 220. Specifically, the first tab and the first protrusion 220 can be electrically connected by welding the first tab and the first protrusion 220. In some cases, due to the small diameter of the first protrusion 220, it is inconvenient to weld it to the first tab. To solve this problem, an adapter 400 can be provided. For details, please refer to Figures 2 to 4 In some embodiments, the battery further includes an adapter 400. The adapter 400 is disposed in the storage cavity 110 and includes a main body 410 and an insulating portion 420. The main body 410 is made of a conductive material, which refers to materials used to transport and conduct current. Conductive materials are primarily categorized into two main types: good conductors and high-resistance materials. In practical applications, common conductive materials include metals, conductive plastics, and conductive rubbers. Metallic conductive materials, such as copper and aluminum, exhibit excellent electrical conductivity and mechanical strength. The insulating portion 420 partially wraps around the main body 410. Specifically, the main body 410 can be made of aluminum or copper, and the insulating portion 420 can be made of insulating glue or insulating varnish. By applying insulating glue to the aluminum, the adapter 400 includes a first connection region 430 (the first connection region 430 is not wrapped around the insulating portion 420, so the main body 410 has the first connection region 430), a second connection region 440, and an insulating region 450. The insulating region 450 refers to the insulated area on the main body 410 after the insulating portion 420 wraps around the main body 410. The insulating region 450 is connected to the wall of the storage cavity 110, thereby insulating the adapter 400 from the housing 100. The first connection region 430 is electrically connected to the first tab, and the second connection region 440 is electrically connected to the first protrusion 220. The configuration of the adapter 400 facilitates welding the first tab to the first connection region 430, and then welding the second connection region 440 to the first protrusion 220, which improves manufacturing efficiency.

[0039] Further, please refer to Figures 2 to 4 In some embodiments, the insulating region 450 is bonded to the wall of the storage cavity 110. Specifically, bonding is low-cost, lightweight, and easy to operate. When the adapter 400 is disposed in the storage cavity 110 and needs to be fixed, the insulating region 450 can be bonded to the wall of the storage cavity 110 using glue. Glue types include polyurethane and epoxy resin, which can achieve a bonding effect while also being resistant to swelling by the electrolyte and affecting long-term viscosity.

[0040] Furthermore, the insulating portion 420 mentioned above is partially wrapped around the main body 410, wherein when the insulating portion 420 wraps around the main body 410, the shape of the main body 410 can be square, and the main body 410 includes two larger surfaces and four smaller surfaces. The insulating portion 420 wraps all four smaller surfaces, and then leaves space on the larger surface for welding with the first tab. Afterwards, a second connection area 440 can be formed by setting a hole, and the insulating portion 420 is wrapped near the hole, so that the first protrusion 220 is connected to the second connection area 440. For details, please refer to Figures 2 to 4 In some embodiments, the second connection region 440 is provided with a second through-hole 441, and the first protrusion 220 is connected to the hole wall of the second through-hole 441. That is, the hole wall of the second through-hole 441 is not provided with the insulating portion 420, but the insulating portion 420 is provided around the second through-hole 441. This can achieve electrical connection between the first protrusion 220 and the second connection region 440, and can also achieve insulation between the insulating region 450 and the cavity wall of the storage cavity 110.

[0041] Further, please refer to Figures 2 to 4 In some embodiments, the first connection region 430 is located on the side of the adapter 400 facing away from the wall of the storage chamber 110. Specifically, the location of the first connection region 430 can exist in various situations, such as being located on the side of the adapter 400 (the surface in the thickness direction of the adapter 400), or being located on the surface of the adapter 400 facing away from the wall of the storage chamber 110. The first connection region 430 being located on the side of the adapter 400 facing away from the wall of the storage chamber 110 facilitates welding between the first tab and the first connection region 430, thereby achieving electrical connection between the first tab and the first connection region 430.

[0042] Further, the specific structure of the insulating member 300 is described below. Figures 2 to 4In some embodiments, the insulating member 300 includes a second body portion 310 and a second protruding portion 320. The second body portion 310 is connected to the second protruding portion 320, and the second protruding portion 320 protrudes relative to the second body portion 310. The insulating member 300 can be T-shaped, with both sides of the second body portion 310 connected to the first body portion 210 and the housing 100, respectively. Specifically, one side of the second body portion 310 can be connected to one side of the first body portion 210, and the other end of the second body portion 310 can be connected to the surface of the housing 100 facing away from the cavity wall of the storage cavity 110. The second protruding portion 320 is provided with a third through hole 321. The second protruding portion 320 is disposed in the first through hole 120, and the first protruding portion 220 is disposed in the third through hole 321. After the first protrusion 220 is disposed in the third through hole 321, the first protrusion 220 can be indirectly disposed in the first through hole 120. The second protrusion 320 connects the hole wall of the first through hole 120 and the first protrusion 220 on both sides, respectively. This can achieve insulation between the first protrusion 220 and the hole wall of the first through hole 120, thereby effectively improving the safety of the battery.

[0043] Further, please refer to Figures 2 to 4 In some embodiments, an insulating layer is provided on one side of the first body portion 210 near the insulating member 300. Specifically, the insulating layer provided on one side of the first body portion 210 may be provided by providing insulating glue or other insulating materials on the first body portion 210, thereby further effectively ensuring insulation between the first body portion 210 and the insulating member 300, which can effectively improve the safety of the battery.

[0044] Furthermore, in some embodiments, the first body portion 210 is bonded to the insulating member 300. Specifically, bonding is convenient, low-cost, and lightweight. By bonding the first body portion 210 and the insulating member 300, insulation between the connector 200 and the insulating member 300 can be achieved. When installing the connector 200 and the insulating member 300 on the housing 100, the connector 200 and the insulating member 300 can be bonded first, and then the insulating member 300 can be bonded to the housing 100, which can improve work efficiency. Specifically, in some embodiments, the insulating member 300 is bonded to the housing 100. The way the insulating member 300 is bonded to the housing 100 also helps improve work efficiency.

[0045] In some embodiments, the electronic device includes the battery of any one of the above embodiments. Specifically, the insulating member 300 is arranged between the first body portion 210 and the shell 100, which can achieve insulation between the first body portion 210 and the shell 100, and the first protrusion 220 is arranged in the first through hole 120 and electrically connected to the first pole ear, which can realize charging and discharging of the battery cell with the outside world through the connector 200. In the prior art, after the first pole ear and the pole are connected, an insulating sheet needs to be arranged between the pole and the shell 100 for insulation, which will result in a lower energy density of the battery. In the present application, the setting of the insulating sheet is omitted, thereby improving the energy density of the battery. Specifically, the battery can have a higher energy density. Furthermore, the electronic device with this battery has a better endurance.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various modifications can be made within the scope of knowledge possessed by a person skilled in the art without departing from the spirit of the present invention.
