Secondary battery

摘要

A secondary battery in which a carbon deposition material made by vapor phase pyrolysis using a hydrocarbon or its derivatives as a raw material is employed as an anode active material and a nonaqueous organic solvent in which a lithium salt is dissolved is employed as an electrolyte. The nonaqueous organic solvent is a mixed solvent of a high dielectric solvent whose donner number is less than 24 and an ethers solvent of a low viscosity whose donner number is less than 24.
