(57) [Problem] To provide a non-aqueous electrolyte battery in which high-rate characteristics and low-temperature characteristics of a battery are not deteriorated even when a low porosity electrode is used due to high energy density. A positive electrode, a negative electrode, a separator, and a non-aqueous electrolyte, wherein the porosity of the positive electrode is 25% or less and the salt concentration of the non-aqueous electrolyte exceeds a concentration giving a conductivity peak. A non-aqueous electrolyte battery was used. |
