Button lithium battery capacitor and assembly method thereof

The invention belongs to the technical field of lithium battery capacitors and discloses an anode shell and a cathode shell, the anode shell and the cathode shell are fastened mutually and form a placement cavity, a winding core is arranged in the placement cavity, an anode end and a cathode end of the winding core respectively form an included angle with a winding direction of the winding core and extend out oppositely to be turned onto the upper lateral surface and the lower lateral surface of the winding core, and the anode end and the cathode end are connected to inner sides of the anode shell and the cathode shell respectively. The placement cavity is internally provided with electrolyte or a polymer electrolyte membrane. Since the anode end and the cathode end of the winding core respectively form the included angle with the winding direction of the winding core and extend out oppositely, in winding of the winding core, adhesive attachment to the winding core can be directly completed along the winding
