Cathode and electrochemical cells for high current density and high power density electrochemical cells.

摘要

A cathode comprising a current collector coated with a dispersion of (CF<Sub>x</Sub>)<Sub>n</Sub> wherein x is equal to or less than 1.2 and n is an indeterminately large number, a current carrier and a' binder characterized in that the current collector is a conductive foil, the binder is sufficiently adhesive to adhere the coated dispersion to the conductive foil and the coated dispersion has a porosity greater than 43 percent. The cathodes are useful in electrochemical cells having light metal anodes.
