BATTERY CELL, BATTERY PACK, AND ELECTRONIC DEVICE

A battery cell (100), a battery pack (700), and an electronic device (800) are provided. The battery cell (100) includes a housing (1), an electrode assembly (2), and a current collecting plate (3). A first extension portion (31) of the current collecting plate (3) extends from a main body portion (30) along a radial direction of the main body portion (30) to be in contact with an outer tab (21). A second extension portion (32) is connected to the main body portion (30) between the two adjacent first extension portions (31). The second extension portion (32) is formed with an outer edge surface along a circumferential direction. The outer edge surface is projected orthographically onto a plane where the outer tab (21) is located to form an outer edge surface projection (9032) at least partially overlapping each outer tab (21) between the two adjacent first extension portions (31).
