HIGH RATE CARBON CATHODE, METHOD OF MAKING, AND ELECTROCHEMICAL CELL INCLUDING THE CATHODE

摘要

A high rate carbon cathode is made by mixing a carbon powder having a surface area of about 1000 square meters/gram with polytetrafluoroethylene and a sufficient amount of water to form a coherent mixture. The mixture is applied to an electrically conductive screen; the cathode formed while wet to an intermediate thickness, the cathode vacuum dried at about 100 degrees C. and the cathode cold compressed to obtain a final electrode porosity of greater than 80 percent. The cathode can be used in lithium primary cell using a solution of an inorganic lithium salt in sulfuryl chloride as the electrolyte.
