Abstract

This invention relates to an electrode assembly, a filling fixture, and a preparation method thereof. The filling fixture includes a jig, which comprises a positioning seat and a cover plate. The bottom end of the cover plate has a first clamping surface, and the top end of the positioning seat forms a second clamping surface. A first through hole is provided on the cover plate. The bottom end of the filling head is a filling end for insertion into the first through hole. A filling channel is provided inside the filling head, and the filling channel has an annular discharge port located inside the filling end. The cross-sectional width of the annular discharge port decreases from top to bottom. This invention also discloses an electrode assembly and its preparation method. This invention can effectively improve the preparation efficiency and quality of the electrode assembly.
