Abstract
The present invention provides a non-aqueous secondary battery having an improved charge and discharge cycle property and high discharge voltage, high energy density, high capacity and increased stability as well as an excellent high electric current atitude by using a lithium-containing transition metal oxide as a positive electrode material and at least one of the specfified composite oxides as a negative electrode material. Accordingly, the feature of the present invention consists in that the negative electrode material mainly consists of at least one member selected from the group consisting of amorphous chalcogen compounds and amorphous oxides containing at least three atoms selected from the group consisting of Group 13, 14, 15 and 2 atoms of Periodic Table.
