Embodiment 1

[0126] Both the first layer and the second layer are connected with the first metal plate and the second metal plate for gluing, and then the first metal plate and the second metal plate are respectively welded with the first tab and the second tab, wherein The order of the gluing process and the welding process can be interchanged. Next, the first electrode, the second electrode and the separator are wound together to obtain an electrode assembly. Then carry out liquid injection, chemical formation, and encapsulation to make such as figure 2 battery shown.

Abstract

The present application discloses a battery including a first electrode, a second electrode, a first layer and a case. The first electrode includes a first conductor having a first surface and a second surface, and a first metal plate connected to the first surface of the first conductor. The second electrode includes a second electrical conductor having a third side and a fourth side, and a second metal plate connected to the third side of the second electrical conductor. The first layer includes insulating material and is connected to the first surface of the first metal plate and the third surface of the second metal plate. The casing includes a first part and a second part, and covers the first electrode, the second electrode and at least a part of the first layer through the first part and the second part, and at least a part of the first part is connected with the first layer.

Description

technical field [0001] The present application relates to the field of energy storage devices, and in particular, to a battery. Background technique [0002] The current energy storage methods mainly include electrochemical energy storage, mechanical energy storage and electromagnetic energy storage. Electrochemical energy storage occupies more and more positions in the future energy storage field due to its high energy density, long life, and fast response speed. to a larger proportion. In the soft-packed battery, the tabs protruding from the head of the cell protrude from the packaging bag, and this structure will cause the problem of reduced air tightness of the packaging bag. SUMMARY OF THE INVENTION [0003] An object of the present application is to provide a battery capable of suppressing the occurrence of a phenomenon in which the airtightness of the case is lowered due to the arrangement of the first metal plate and the second metal plate. [0004] Some embodime...
