Title: CARBON ELECTRODE MATERIAL FOR ELECTROCHEMICAL CELLS AND METHOD OF MAKING SAME
Abstract:
A method (50) of fabricating an amorphous carbon material for use as an electrode (20) in a rechargeable electrochemical cell (10) includes the steps of heating (62) a lignin material until it has fully cured, comminuting (68) the lignin material before it has carbonized, and subsequently heating (70) the lignin material until it has carbonized.
