PURPOSE: A non-aqueous secondary battery is provided to have excellent cycle property in wide temperature range, which is from low-temperature zone to high-temperature zone. CONSTITUTION: A non-aqueous secondary battery has a structure in which a positive electrode, a negative electrode, and non-aqueous electrolyte are accepted inside external body. The positive electrode comprises a positive electrode active material consisting of lithium transition metal composite oxide, and the negative electrode material comprises a negative electrode active material consisting of carbon material. The weight of non-aqueous electrolyte liquid per the battery capacity of the non-aqueous secondary battery is 10.0-12.0 g/Ah, and the volume of non-aqueous electrolyte liquid per the void volume of the non-aqueous secondary battery is 70-85 %. |
