Abstract

The embodiment of the invention relates to a battery component and an electrochemical device. The battery component provided by one embodiment of the invention comprises a first end; a first cell; a second battery cell stacked with the first battery cell, wherein each of the first battery cell and the second battery cell comprises a first tab and a second tab, one of the first tab and the second tab of the first battery cell is configured to be electrically connected with one of the first tab and the second tab of the second battery cell to form a first series tab component, or the first tab and the second tab of the first battery cell are configured to be electrically connected with the first tab and the second tab of the second battery cell respectively to form a first parallel tab component; and a first insulator which at least covers the first end and is positioned in a gap of the first series tab component or the first parallel tab component at the first end. According to the battery component and the electrochemical device provided by the embodiment of the invention, the connection between the soft package battery and the outside can be achieved through a simple structure, and meanwhile, the battery component has the good mechanical resistance and environmental resistance.

Description

technical field [0001] The embodiments of the present application relate to the field of batteries, in particular to battery components and electrochemical devices. Background technique [0002] Soft pack batteries have been widely used in various electronic products and electric vehicles and other fields. In the prior art, the connection between the tabs of the pouch battery and the outside of the pouch battery is usually achieved by using a combination of an adapter plate or a bracket and a copper bar. However, such a technical solution has many disadvantages such as high material cost, complex structure, cumbersome production process and low production efficiency. [0003] Therefore, there are still quite a lot of technical problems in the industry that need to be solved urgently for how to realize the connection between the tabs of the pouch battery and the outside with a relatively simple structure and process. Contents of the invention [0004] One of the objective...
