Non-aqueous electrolyte secondary batteries
A non-aqueous secondary battery comprising a positive electrode comprising a lithium-containing metal oxide, and a negative electrode comprising a carbon material as the active material is disclosed. The electrodes are separated by either a separator impregnated with organic electrolyte solution or by a solid electrolyte layer. The negative electrode comprises a mixture of the carbon material and at least one metal oxide selected from TiO2, Cr2O3, MnO2, Fe3O4, CoO, Co2O3, Co3O4, NiO, Ni2O3, Ag2O, PbO, Sb2O3, Bi2O3, SeO2, and TeO2.
