Abstract

A non-aqueous electrolyte battery of the present invention includes a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte, and the separator contains polyphenylenesulfide fibers, aramid fibers, and cellulose fibers at ratios of 50 to 85 mass %, 10 to 30 mass %, and 5 to 35 mass %, respectively. This makes it possible to provide a non-aqueous electrolyte battery with characteristics that are less likely to deteriorate under a high-temperature environment and in which few defects occur during assembly.
