ABSTRACT:
The present invention provides a secondary electrochemical cell comprising a body of aprotic, non-aqueous electrolyte, first and second electrodes in effective electrochemical contact with the electrolyte, the first electrode comprising active materials such as a lithiated intercalation compound serving as the positive electrode or cathode and the second electrode comprising a carbon-carbon composite material infiltrated with polymeric binder and serving as the negative electrode or anode. Such an electrochemical cell has improved mechanical properties and cycle life as compared with similar secondary non-aqueous electrochemical cells having carbon-carbon composite anodes that are not incorporated with polymeric binder.
