Disclosed is a battery non-aqueous electrolyte containing a lithium salt having a specific structure containing a boron atom or a phosphorus atom, and capable of reducing battery resistance. A nonaqueous electrolysis for a battery comprising a compound represented by the following general formula (A), wherein the content of copper element is 0.001 mass ppm or more and less than 5 mass ppm with respect to the total amount of the nonaqueous electrolyte for a battery. Liquid [M represents a boron atom or a phosphorus atom, X represents a halogen atom, R represents an alkylene group having 1 to 10 carbon atoms, a halogenated alkylene group having 1 to 10 carbon atoms, or 6 to 20 carbon atoms] An arylene group or a halogenated arylene group having 6 to 20 carbon atoms (these groups may include a substituent or a hetero atom in the structure), and m represents an integer of 1 to 3. , N represents an integer of 0 to 4 and q represents 0 or 1].
