BATTERY CELL, BATTERY MODULE, BATTERY PACK, AND ELECTRICAL APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18343758 titled 'BATTERY CELL, BATTERY MODULE, BATTERY PACK, AND ELECTRICAL APPARATUS

Simplified Explanation

The patent application describes a battery cell, module, pack, and electrical apparatus.

  • The battery cell has an intermediate portion and side portions.
  • The intermediate portion consists of m battery cell sub-units, while the side portions consist of n battery cell sub-units.
  • The total number of sub-units (m+n) is an integer greater than or equal to 3.
  • Each battery cell sub-unit includes a positive electrode sheet, a negative electrode sheet, and a separator.
  • The m battery cell sub-units have a higher dry battery cell nail penetration short-circuit resistance compared to the n battery cell sub-units.


Original Abstract Submitted

A battery cell, a battery module, a battery pack, and an electrical apparatus are provided. The battery cell includes an intermediate portion and side portions located on two sides of the intermediate portion in a thickness direction, the intermediate portion comprising m battery cell sub-units and the side portions comprising n battery cell sub-units, where m+n is an integer greater than or equal to 3. Each of the battery cell sub-units comprises a positive electrode sheet, a negative electrode sheet and a separator arranged between the positive electrode sheet and the negative electrode sheet, and each of the m battery cell sub-units has a dry battery cell nail penetration short-circuit resistance greater than that of each of the n battery cell sub-units.
