Abstract
An electrode assembly formed by winding a first electrode plate, a separator and a second electrode plate. The first electrode plate comprises a first current collector and a first active material layer arranged on a surface of the first current collector. A winding terminating end of the first electrode plate is positioned on an outer side of a winding terminating end of the second electrode plate facing away from a winding core. The first active material layer on the winding terminating end of the first electrode plate covers one surface of the first current collector facing toward the second electrode plate, The electrode assembly further comprises a first adhesive member arranged on an outer surface of the electrode assembly. The electrode assembly takes the winding terminating end of the first electrode plate as the tail end. The application further provides a battery having the same.
