Sekundärbatterie mit nichtwässrigem Elektrolyten

摘要

An object is to provide a non-aqueous electrolyte secondary battery having a higher capacity without sacrificing the cycle life. For achievement of the object, a positive electrode made of lithium contained metal oxide and a negative electrode made of a carbon material as the primary 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, Cr203, MnO2, Fe3O4, CoO, Co2O3, Co3O4, NiO, Ni2O3, Ag2O, PbO, Sb2O3, Bi203, SeO2, and TeO2.
