COMPOSITE CATHODE FRAME ASSEMBLY, BATTERY CELL, AND ASSEMBLY METHOD FOR BATTERY CELL

A composite cathode frame assembly, a battery cell, and an assembly method for a battery cell. The composite cathode frame assembly comprises a frame (1), a cathode sheet (2), and separators (3); an accommodating recess (14) for allowing the cathode sheet (2) to be embedded in is formed in the frame (1); the separators (3) are fitted onto two surfaces of the frame (1); and the separators (3) are attached to the surfaces of the frame (1) and cover the cathode sheet (2) and the frame (1). The battery cell comprises the composite cathode frame assembly, a packaging sleeve (5), and an anode sheet (4). The present application achieves the effect of reducing the battery cell manufacturing difficulty while accurately keeping the overhang requirement of battery cells. L'invention concerne un ensemble cadre de cathode composite, un élément de batterie et un procédé d'assemblage pour un élément de batterie. L'ensemble cadre de cathode composite comprend un cadre (1), une feuille de cathode (2) et des séparateurs (3) ;
