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.
