Patent ID: 8685568

Claim:
An electrochemical cell, which comprises: a) an anode comprising lithium; b) a cathode comprising: i) 90 to 98 weight percent fluorinated carbon fibers having a general formula of C 2 F or CF x with x ranging from 0.5 to 1.2 and an aspect ratio of from 2 to 25 as a cathode active material; ii) up to 5 weight percent of a conductive additive other than the fluorinated carbon fibers to thereby form a cathode active mixture; and iii) a current collector selected from the group consisting of titanium, aluminum, stainless and carbon supporting the fluorinated carbon/conductive additive cathode active mixture, iv) wherein when the current collector is one of titanium, aluminum and stainless steel, it is provided with a coating selected from the group consisting of carbon, noble metals and a carbide-type material so that the fluorinated carbon does not physically touch the current collector, but is in electrical continuity there with; and c) a separator preventing direct physical contact between the anode and the cathode; and d) an electrolyte having a conductivity of at least 1Ã—10 âˆ’2 S/cm at 37Â° C. activating the anode and the cathode.
