ABSTRACT:
A nonaqueous secondary battery has high energy density and excellent charging and discharging cycle characteristic. The constitution includes (a) a positive electrode having a positive electrode substance, (b) a negative electrode having an carbon fluoride, and a carbon material, and (c) an electrolyte solution. The positive electrode substance is capable of releasing and occluding lithium ions in charging and discharging, the carbon material is capable of occluding and releasing the lithium ions in the charging and discharging, the carbon fluoride is capable of reacting chemically with the lithium ions, and the electrolyte solution is a nonaqueous electrolyte solution. The carbon fluoride is expressed by chemical formula (C.sub.x F).sub.n.
