Claims
- 1. 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 at least one negative electrode thin film layer and, beside said negative electrode thin film layer, at least one negative electrode active material compound layer, on a negative electrode current collector, wherein:
said negative electrode thin film layer containing at least one Group 14 element, and being formed by a thin-film formation technology, and said negative electrode active material compound layer containing 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.
- 2. The non-aqueous electrolyte battery as claimed in claim 1, wherein said negative electrode thin film layer contains at least any one of Sn, Si, Sn compound, Si compound and carbonaceous material.
- 3. The non-aqueous electrolyte battery as claimed in claim 1, wherein said negative electrode thin film layer has a thickness within a range from 1 μm to 30 μm.
- 4. A method of manufacturing a non-aqueous electrolyte battery having a non-aqueous electrolyte containing an electrolyte salt, comprising the steps of:
fabricating a positive electrode which has a positive electrode active material compound layer containing a positive electrode active material formed on a positive electrode current collector; and fabricating a negative electrode having at least one negative electrode thin film layer and, beside said negative electrode thin film layer, at least one negative electrode active material compound layer, formed on a negative electrode current collector, wherein:
said negative electrode thin film layer containing at least one Group 14 element, and being formed by a thin-film formation technology, and said negative electrode active material compound layer containing a binder and a negative electrode active material, which contains at least any one of Sn, Si, Sn compound, Si compound and carbonaceous material.
- 5. The method of manufacturing a non-aqueous electrolyte battery as claimed in claim 4, wherein in the fabrication of said negative electrode, at least any one of Sn, Si, Sn compound, Si compound and carbonaceous material is included in said negative electrode thin film layer.
- 6. The method of manufacturing a non-aqueous electrolyte battery as claimed in claim 4, wherein in the fabrication of said negative electrode, said negative electrode thin film layer is formed so as to have a thickness within a range from 1 μm to 30 μm.
