    摘要： 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.

    摘要： There is provided a secondary battery comprising a positive and a negative electrode and a nonaqueous electrolyte. The positive electrode is made by dipping an electrode comprising a positive active material such as LiMn.sub.2 O.sub.4, LiMnO.sub.2, LiCoO.sub.2, LiNiO.sub.2, LiFeO.sub.2 or .gamma.LiV.sub.2 O.sub.5, in a solution containing butyllithium, phenyllithium, or naphthyllithium. The negative electrode of the battery absorbs and desorbs lithium by charging and discharging, and the nonaqueous electrolyte contains a lithium salt. Also provided is a method of manufacturing a secondary battery comprising a nonaqueous electrolyte. The method comprises the steps of preparing an electrode group containing a positive electrode of LiMn.sub.2 O.sub.4, LiMnO.sub.2, LiCoO.sub.2, LiNiO.sub.2, LiFeO.sub.2 or .gamma.-LiV.sub.2 O.sub.5, as the active material, and a negative electrode which absorbs and desorbs lithium by charging and discharging, with a separator therebetween. The group is placed in a battery case, and to the case is added a solution containing butyllithium etc. The solution is removed and an organic electrolyte as a nonaqueous electrolyte is added to the battery case.
