The battery comprises 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; a negative
electrode which has at least one negative electrode thin film layer and
at least one negative electrode active material compound layer, on a
negative electrode current collector, and a non-aqueous electrolyte
containing an electrolyte salt. The negative electrode thin film layer
contains at least one Group 14 element, and is formed by a thin-film
formation technology, and the 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. With this negative electrode, the negative
electrode thin film layer containing a high-capacity Group 14 element
raises the battery capacity, and the negative electrode active material
compound layer provides excellent charge/discharge cycle characteristics
while suppressing degradation of the negative electrode even under
repetitive charge/discharge.
