BATTERY CELL AND BATTERY PACK - A simplified explanation of the abstract

This abstract first appeared for US patent application 18427675 titled 'BATTERY CELL AND BATTERY PACK

Abstract: This application discloses a battery cell and a battery pack. The battery cell includes a housing and a bare cell located in an inner cavity of the housing. The bare cell includes at least two opposite extension ends and a middle region located between the two opposite extension ends of the bare cell. The two opposite extension ends of the bare cell are configured to be lower than the middle region of the bare cell in a height direction. The bare cell of this cell forms a structure that is high in the middle and low at edges, and a liquid level height of an electrolyte solution in the housing is below the middle region of the bare cell and above extension ends.

Simplified Explanation:

The patent application describes a unique battery cell design where the bare cell is structured to be higher in the middle and lower at the edges, with the electrolyte solution level positioned accordingly.

Key Features and Innovation:

- Bare cell design with high middle and low edges - Electrolyte solution level below middle region and above extension ends - Housing and inner cavity for the bare cell
