| 摘要 |
An object of the invention is to provide a nonaqueous electrolyte secondary battery exhibiting high output characteristics in low-temperature environments, the nonaqueous electrolyte secondary battery being a lithium ion battery which uses a lithium manganese composite oxide as a positive electrode active material and a lithium titanium composite oxide as a negative electrode active material. The nonaqueous electrolyte secondary battery wherein the positive electrode active material contains a lithium-manganese composite oxide containing lithium and manganese as constituent elements, the negative electrode active material contains a lithium-titanium composite oxide containing lithium and titanium as constituent elements, and the separator contains inorganic particles is used. |
