PURPOSE:To obtain a nonaqueous electrolyte battery having a high discharge characteristic after being stored over a long period of time by using 1,3-dioxacyclohexane-2-on alone or a mixture solution containing said compound as the solvent of nonaqueous electrolyte. CONSTITUTION:The solvent of nonaqueous electrolyte consists of 1,3-dioxacyclohexane-2-on alone or a mixture solution containing the above compound. A solvent used for the conventional nonaqueous electrolyte battery can be used as another solvent used for preparing the mixture solution. In order to improve the discharge characteristic of a nonaqueous electrolyte battery observed after it is stored over a long period of time, addition of not less than 20vol% of 1,3- dioxacyclohexane-2-on is appropriate and addition of not less than 40vol% of the above compound is preferred. |
