Patent ID: 7261976

Claim:
A non-aqueous electrolyte battery comprising: a positive electrode having a positive electrode active material compound layer containing a positive electrode active material, on a positive electrode current collector; a negative electrode having a negative electrode thin film layer formed directly on and in contact with a negative electrode current collector, and, a negative electrode active material compound layer formed on said negative electrode thin film layer, the negative electrode thin film layer being disposed between the negative electrode current collector and the negative electrode active material compound layer, a separator disposed between and directly in contact with the positive electrode and the negative electrode active material compound layer, wherein: said negative electrode thin film layer contains at least one Group 14 element, and is formed by a thin-film formation technology, and said negative electrode active material compound layer contains a binder and a negative electrode active material, which contains at least any one of Sn, Si, Sn compound, Si compound and carbonaceous material; and a non-aqueous electrolyte containing an electrolyte salt.
