PROBLEM TO BE SOLVED: To improve the energy quantity and cycle lifetime of a lithium secondary battery. SOLUTION: Transition metal oxide containing lithium is used as a positive electrode active material, and the compound containing silicon atom is used as a negative electrode material, and a material having a volume resistivity at 102 Ω.cm or less is used as the negative electrode conductive agent. One or more kinds of material is selected as the described material from among metals such as metal powder, metal flake, metal fiber and the carbon compound such as carbon black, graphite and carbon fiber. |
