Abstract

The present application relates to the technical field of batteries, and discloses a battery and an assembly method therefor. The battery includes: a shell having a first end and a second end that are arranged opposite, where the first end is configured as a first open end, an edge of the second end extends along a radial direction of the shell towards an axis direction of the shell to form an extension ring, a central area of the extension ring forms a second open end, and the second open end is smaller than the first open end; an electrode assembly mounted in the shell; a positive electrode cover plate arranged at the first end of the shell and fixedly connected to the shell to seal the first open end; a positive electrode column mounted on the positive cover plate in an insulating manner and electrically connected to a positive electrode of the electrode assembly; and a negative electrode cover plate arranged at the second end of the shell and electrically connected to a negative electrode of the electrode assembly, where the negative electrode cover plate is fixedly connected to at least a portion of the extension ring to seal the second open end. The present application changes conventional peripheral welding to top straight welding, achieving easy operation, high welding efficiency, good connection performance, large welding area, and good battery performance.
