PURPOSE: To provide a nonaqueous electrolyte having self fire extinguishing action, high withstand voltage, and excellent application to a battery such as charge/discharge performance. CONSTITUTION: Lithium salt of phosphoric ester in a general formula is added to a nonaqueous electrolyte including preferably chainlike ester and/or annular ester as an organic solvent, and also including the lithium salt, preferably LiPF6 , as an electrolyte. In the formula, R<1> and R<2> can be the same or different to express an alkyl group having a number of carbon of 1-4 or a halogen atom substituting alkyl group having a number of carbon of 2-3 respectively, and any one of the R<1> and R<2> can be a lithium ion. |
