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 disposed within the housing. The housing is shaped as a right parallelepiped and defined by three mutually perpendicular dimensions: W1, T1, and H1. The housing comprises six walls: opposing first and second walls along the W1 direction, opposing third and fourth walls along the T1 direction, and opposing fifth and sixth walls along the H1 direction. The sum of the thicknesses of each pair of opposing walls is denoted as a, b, and c, respectively. The effective internal volume ratio of the housing satisfies (W1−a)×(T1−b)×(H1−c)/(W1×T1×H1)≥90%. This configuration enhances the volumetric energy density of the battery cell while maintaining the same chemical material system.
