Abstract
A battery cell, a battery, an electric apparatus, and an energy storage apparatus are provided. The battery cell includes a housing and at least one electrode assembly positioned within the housing. The housing is a right parallelepiped defined by three mutually perpendicular dimensions: W, T, and H. The housing comprises six walls, arranged in opposite pairs along each direction. The combined thicknesses of the two opposite walls in each direction are denoted as a, b, and c, respectively. The ratio of usable internal volume to total external volume, defined as (W−a)·(T−b)·(H−c)/(W·T·H), is not less than 90%. This structural configuration increases the volumetric energy density of the battery cell using the same chemical system.
