| abstract |
The nonaqueous electrolyte battery of the present invention comprises a positive electrode, a negative electrode, a separator, and a nonaqueous electrolyte solution, wherein the separator comprises 50 to 85% by mass, 10 to 30% by mass of polyphenylene sulfide fiber, aramid fiber and cellulose fiber, 5 to 35% by mass. As a result, it is possible to provide a nonaqueous electrolyte battery in which deterioration of characteristics under a high temperature environment is suppressed and defects are small during assembly. |
