Non-aqueous electrolyte battery |
摘要 |
A non-aqueous electrolyte battery is provided that can prevent working voltage of the battery from decreasing even when the battery is stored in high temperature conditions. A non-aqueous electrolyte battery includes: a positive electrode having a positive electrode active material-layer and a positive electrode current collector, a negative electrode having a negative electrode active material layer; and a separator interposed between the electrodes. The positive electrode active material-layer is formed on a positive electrode current collector surface and includes a plurality of layers having different positive electrode active materials, wherein a lowermost layer of the plurality of layers that is in contact with the positive electrode current collector contains as its main active material a positive electrode active material having the lowest end-of-charge working voltage among the positive electrode active materials.
