(57) [Summary] (with correction) [PROBLEMS] To easily provide a non-aqueous electrolyte battery having high safety and excellent battery performance. SOLUTION: In a non-aqueous electrolyte battery comprising at least a positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte containing a lithium salt, the non-aqueous electrolyte contains an imidazolium cation having a skeleton represented by the following general formula 2. A room-temperature molten salt having a quaternary ammonium cation is contained as a main component, and the separator has an organic polymer layer formed on at least a part of the surface of the porous substrate or in the pores, and A non-aqueous electrolyte battery having a structure formed so as to allow gas to enter the inside of a porous substrate from the inside. However, R 1, R 2: C n H 2n + 1, n = 1~6 R 3: H or C n H 2n + 1, n = 1~6 |
