First Claim
Patent Images
1. A method of manufacturing a lithium ion battery, the method comprising:
- dry milling dry carbon particles, dry lithium compound particles, and dry binder consisting essentially of fibrillizable binder particles, wherein the dry milling is performed in the absence of solvent and additional binders to form a milled dry cathode powdered mixture;
feeding the milled dry cathode powdered mixture to rollers;
calendering the milled dry cathode powdered mixture between the rollers to form a dry cathode film;
applying the dry cathode film to an electrically conductive substrate to form the cathode;
providing an anode; and
placing the cathode and the anode in a housing comprising an electrolyte to form the lithium ion battery.
