description A battery cell including a first electrode plate and a second electrode plate alternately stacked, where a separator is disposed there between. The first electrode plate includes a first current collector and a first active substance layer. The second electrode plate includes a second current collector and a second active substance layer. The first electrode plate further includes a first recess formed by absence of the first active substance layer on the surface of the first current collector and a first tab disposed in the first recess. The second electrode plate includes a second recess formed by absence of the second active substance layer. In a thickness direction of the battery cell, the first recess and the second recess are arranged opposite to each other. A first insulation layer is disposed on a surface of the first tab, and the second recess is provided with a first insulation holding member.
