A high rate carbon cathode is made by mixing a carbon powder having a surface area of about 1000 square metersgram 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 a lithium primary cell using a solution of an inorganic lithium salt in sulfuryl chloride as the electrolyte. Author
