Abstract

The present application is applicable to the technical field of power batteries, and provides an electrode assembly (400) and an adhesive tape application method therefor, a battery cell (300), a battery (200), and an electric device (100). The electrode assembly comprises: a first covering member (60) provided on the surface of the electrode assembly, the first covering member being provided with an information pattern; and a second covering member (70) provided on the surface of the electrode assembly, the information pattern being exposed outside the second covering member. According to the present application, the second covering member covers the surface of the electrode assembly, so that the electrode assembly is protected by the second covering member, thus reducing the impact of the external environment on the electrode assembly; and when the second covering member covers the electrode assembly, the information pattern can be exposed outside the second covering member, thus reducing the impact of the second covering member on the first covering member, so that an identification device can identify information recorded on the first covering member.
