Abstract
An alkali metal/solid cathode electrochemical cell, such as of a Li/SVO couple, having the cathode material supported on a titanium current collector screen coated with a carbonaceous material is described. The thusly-coated titanium current collector provides the cell with higher rate capability in comparison to cells of a similar chemistry having the cathode active material contacted to an uncoated titanium current collector.
Claims5
An electrochemical cell, which comprises:
- a) an anode comprising lithium;
- b) a cathode comprising a solid cathode active material contacted to a conductive current collector comprising titanium provided with a carbonaceous coating;
- and
- c) an electrolyte activating the anode and the cathode.
