ABSTRACT:
A process of making a negative electrode for a storage battery including a positive electrode capable of being reversibly charged and discharged, a nonaqueous electrolyte containing lithium salt, and a negative electrode is provided. The negative electrode is made of an inorganic carbon material which has an improved surface having a specific surface area sufficiently large enough to store the largest possible amount of lithium ions therein to provide the largest possible charge and discharge capacitances for the storage battery. The electrode is made by adding an acid to an inorganic carbon containing material to form a mixture, heating the mixture for at least 10 hours to obtain a carbon material having a specific surface area of more than 8.0 m.sup.2 /g and forming the electrode using the carbon material.
