The nonaqueous electrolyte battery of the present invention includes a positive electrode, a negative electrode, a separator and a nonaqueous electrolyte, and the separator contains polyphenylene sulfide fibers, aramid fibers and cellulose fibers, respectively, 50 to 85% by mass and 10 to 30% by mass, It is contained in a ratio of 5 to 35% by mass. Accordingly, it is possible to provide a non-aqueous electrolyte battery in which deterioration of characteristics in a high-temperature environment is suppressed and defects are less generated during assembly. |
