Modified cokes or blacks suitable as alkali metal intercalation electrodes in electrochemical cells are produced by a method comprising boiling the coke or black in concentrated hydrochloric acid, flushing with distilled water, sonicating the coke or black in acetone, and drying the coke or black at a temperature of 150 to 300° C. The modified cokes and blacks produced by this method show Intercalation capacities up to 50% higher than unmodified cokes and blacks, and maintain the high electrolyte compatibility, rate capability and cyclability of the cokes or blacks. |
