Non-aqueous electrolyte secondary batteries

摘要

A positive electrode made of lithium contained metal oxide and a negative electrode made of a carbon material as active material are separated by a separator impregnated with organic electrolyte solution or a solid electrolyte layer. In particular, the carbon material is added with the metal oxide which can electrochemically be reduced by charge to generate a metal. The metal oxide consists mainly of a mixture of the carbon material and at least one metal oxide selected from a group of TiO2, Cr2O3, MnO2, Fe3O4, CoO, Co2O3, Co3O4, NiO, Ni2O3, Ag2O, PbO, Sb2O3, Bi2O3, SeO2, and TeO2.
