ABSTRACT:
A non-aqueous electrolyte battery and a method of manufacturing the battery are provided. The non-aqueous electrolyte battery has a positive electrode including a positive electrode active material-layer stack containing a plurality of different positive electrode active materials and formed on a positive electrode current collector surface, a negative electrode including a negative electrode active material layer, and a separator interposed between the electrodes. The positive electrode active material-layer stack includes two or more layers respectively containing different positive electrode active material components, and of the two or more layers, the layer nearer the positive electrode current collector is formed by coating the collector with a positive electrode active material having the highest resistance increase rate and a conductive agent contained in that positive electrode active material by cold spraying.
