BATTERY CELL, BATTERY PACK, AND ELECTRIC APPARATUS

Abstract

A battery cell includes a housing, a bare cell, and a pressure relief structure. The housing internally forms an accommodating cavity. The bare cell is accommodated in the accommodating cavity. The pressure relief structure is mounted on a first wall surface of the housing and configured to actuate when a pressure or temperature in the accommodating cavity reaches a threshold to communicate the accommodating cavity with an external space. The first wall surface forms a protruding structure protruding toward an interior of the accommodating cavity, and the protruding structure is configured to abut against the bare cell to form a flow channel between the bare cell and the first wall surface.
