Abstract
The present disclosure relates to a cell, a battery and an electronic device. The cell includes a first electrode sheet and a second electrode sheet. The first electrode sheet includes a first current collector. The second electrode sheet includes a second current collector. The second current collector includes a starting section and a first bending segment connected to the starting section. A current collector opposite to the starting section and the first bending segment is configured as the second current collector. Thus, the cell is not internally provided with an opposite region between the first current collector and the second current collector, which may enhance the energy density of the cell and improve the safety of the cell.
