NON-AQUEOUS ELECTROLYTE BATTERY AND METHOD OF MANUFACTURING THE SAME

摘要

[Problem] A non-aqueous electrolyte battery is provided that shows good cycle performance and good storage performance under high temperature conditions and exhibits high reliability even with a battery configuration featuring high capacity. A method of manufacturing the battery is also provided. [Means for Solving the Problem] A non-aqueous electrolyte battery is characterized in that the positive electrode active material contains at least cobalt or manganese, the separator includes a porous separator main body and a coating layer formed on at least one surface of the separator main body, and the coating layer contains filler particles and a water-insoluble binder.
