Abstract: The present disclosure provides a wound-type cell and a winding mandrel. The wound-type cell comprises: a first electrode plate having a blank first current collector which is positioned at a first winding start end and is not coated with the first active material layer; a second electrode plate having a blank second current collector which is positioned at a second winding start end and is not coated with the second active material layer, and the blank second current collector is positioned at an inner side of the blank first current collector; a separator; a first electrode tab; and a second electrode tab. A first end of the blank first current collector is beyond a second end of the blank second current collector in a length direction, and a position of the first electrode tab is beyond the second end of the blank second current collector in the length direction.
