A new anode material known as "hairy carbon" for use in a secondary electrochemical cell, is described. The hairy carbon electrode material is developed by growing submicron carbon filaments on a carbon substrate. A catalyst is used to initiate hair growth with carbonaceous gases serving as the carbon source. The hairy carbon submicron filaments typically have diameters ranging between about 0.05 .mu.m and 0.2 .mu.m, and the electrode is formed by mixing the hairy carbon material with a suitable binder and pressing the admixture into a desired shape. Hairy carbon is particularly useful as an anode material in a rechargeable alkali metal electrochemical cell due to its excellent reversibility for the intercalation and deintercalation of alkali metal ions over extended discharge and recharge cycles.
