Abstract
A nonaqueous electrolyte battery comprises a positive electrode comprising a mixture of manganese dioxide and a fluorinated graphite as a positive electrode active material, a negative electrode comprising lithium metal or a substance capable of occluding and discharging lithium ion as a negative electrode material, and a nonaqueous electrolyte, said fluorinated graphite being represented by the formula (CFx)n wherein 1.2.ltoreq..times..ltoreq.1.4 and contained in said mixture in a ratio by weight of 0.1 to 4%. This battery undergoes minimal self discharge and has excellent storage capability, since reaction products formed by reaction of manganese dioxide and the nonaqueous electrolyte used minimally react with lithium on the negative electrode side.
