Abstract
A method for preparing a carbon material for use as an electrode, such as the anode (30) of an electrochemical cell (10). The carbon is fabricated in a heating process from a plurality multifunctional organic monomers selected from first and second groups of monomers. Electrodes so fabricated may be incorporated into electrochemical cells (10) as the anode (20) thereof.
Claims17
