Abstract

See full text

The embodiments of the present application provides a wound electrode assembly formed by winding a first electrode sheet, a second electrode sheet, and an isolating membrane disposed therebetween. The wound electrode assembly includes: a first surface having a first protrusion in the thickness direction of the wound electrode assembly; a first wound electrode assembly; a second wound electrode assembly wrapping the first wound electrode assembly, the first wound electrode assembly and the second wound electrode assembly sharing the first electrode sheet and the second electrode sheet; an adhesive layer disposed between the first electrode sheet and the isolating membrane, and/or between the second electrode sheet and the isolating membrane. The purpose of the present application is at least to provide a wound electrode assembly capable of reducing the risk of misalignment of the internal structures of the electrode assembly during the falling, and retaining the shape of the electrode assembly.
