However, there are generally higher requirements for the waterproof performance of the battery cell. If the film on the surface of the battery cell cannot isolate water vapor well, water vapor will enter the battery cell, which may cause a large amount of gas to be generated inside the battery cell, thus causing the cell to be damaged. damage to

Abstract

The application provides a battery which comprises a battery cell, a first protective layer and a second protective layer, wherein the first protective layer wraps the battery cell and is used for isolating electrolyte from flowing out of the battery cell; and the second protective layer totally covers the first protective layer and is used for isolating water vapor from entering the battery cell from the first protective layer. The application further relates to an electronic device. By using the battery, external water vapor can be better isolated, and the problem of gas production caused by water vapor entering the battery cell is avoided.

Description

technical field [0001] The present application relates to the technical field of battery manufacturing, in particular to a battery and an electronic device. Background technique [0002] The surface of the cell is provided with a film for packaging, which is relatively common in the prior art. However, there are generally higher requirements for the waterproof performance of the battery cell. If the film on the surface of the battery cell cannot isolate water vapor well, water vapor will enter the battery cell, which may cause a large amount of gas to be generated inside the battery cell, thus causing the cell to be damaged. damage. Contents of the invention [0003] In view of this, it is necessary to provide a battery and an electronic device that can effectively prevent water vapor from entering the battery cell. [0004] A battery provided by the present application includes a cell, a first protective layer and a second protective layer, the first protective layer co...
