Abstract
The invention discloses a battery shell and a battery. The battery shell is divided into a bottom shell and a sealing cover, and the sealing cover is divided into an outer contact layer, an insulating layer and an inner contact layer. An electrode contact part of the outer contact layer penetrates through the insulating layer and the inner contact layer to be electrically conducted with one electrode of a battery cell, and the other electrode of the battery cell is electrically conducted with the bottom shell. After the inner contact layer and the bottom shell are welded, the battery cell can be packaged. The inner contact layer and the outer contact layer are insulated through the insulating layer, so that the bottom shell is also insulated from the outer contact layer, and the two electrodes of the battery cell can be prevented from being mutually conducted to cause short circuit. The inner contact layer and the outer contact layer of the sealing cover are insulated in advance, so that when the sealing cover is used for packaging the bottom shell, only the inner contact layer and the bottom shell need to be welded. An insulating film does not need to be arranged, the packaging process of the battery can be simplified, and the packaging efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of batteries, in particular to a battery case and a battery. Background technique [0002] Existing button battery, its battery case is spliced and formed by positive electrode casing and negative electrode casing, needs insulation between positive electrode casing and negative electrode casing to avoid short circuit of button cell; An insulating film is provided to achieve insulation, and the positive electrode casing and the negative electrode casing are welded and fixed. During the processing, it is difficult to install the insulating film, which makes the processing of the button battery more difficult and reduces the processing efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide a battery case for button batteries, aiming at solving the technical problem of how to improve the battery processing efficiency. [0004] To achieve the above object, the ...
