CELL, BATTERY, AND ELECTRONIC DEVICE

A cell (1), comprising an electrode assembly (11). The electrode assembly (11) is formed by a first electrode tab (12), a separator (13), and a second electrode tab (14) stacked or coiled in sequence. The first electrode tab (12) comprises a first current collector (121) and a first active material layer (122) provided on either side of the first current collector (121). The first electrode tab (12) also comprises an electrically-conductive layer (123). The first current collector (121) comprises a first surface (1211) and a second surface (1212) facing away from the first surface (1211). The electrically-conductive layer (123) completely covers the first surface (1211) and/or the second surface (1212). The first active material layer (122) is provided on the surface of the electrically-conductive layer (123). Also provided is a battery (10) having the cell (1) and an electronic device (100) having the battery (10). L'invention concerne un élément (1), comprenant un ensemble d'électrode (11).
