PROBLEM TO BE SOLVED: To provide a nonaqueous second battery which is superior in safety and storing nature. SOLUTION: In a nonaqueous second battery which has a positive electrode, a negative electrode and a nonaqueous electrolyte containing a lithium salt, the nonaqueous second battery is constituted from lithium-containing transition metal chalcogenide whose surface is coated with celluloses, as an active material of the positive electrode. As cellulosics, at least one kind of those chosen from a group consisting of carboxymethyl cellulose, carboxymethyl ethly cellulose, ethyl cellulose, hydroxypropylcellulose and their salt is preferable. Further, as the coating amount of celluloses to cost the surface of lithium-containing transition metal chalcogenide, 0.1 to 5% by the weight standard for lithium- containing transition metal chalcogenide is preferable. |
