Abstract:
A method of manufacturing an electrode comprising the steps of:crushing a positive-electrode plate in which positive-electrode mixture layers comprising a thermoplastic binder, a positive-electrode active material and conductive substrates are crushed to form a powder comprising the thermoplastic binder, positive-electrode active material powder and crushed conductive substrates and which is held on a solid formed conductive substrate comprising aluminum foil;at least partially separating the positive-electrode active material powder from the crushed conductive substrates to yield a powder comprising positive-electrode active material powder and not more than 5 wt % crushed conductive substrates;mixing the positive-electrode active material powder and not more than 5 wt % crushed conductive substrates with organic solvent so that a coating material is prepared; andapplying the coating material to the surface of the conductive substrate.
