Abstract
A non-aqueous electrolyte secondary battery includes a positive electrode containing lithium-iron phosphate, and a negative electrode containing a lithium-titanium composite oxide and a lithium composite oxide which is different from the lithium-titanium composite oxide. The lithium composite oxide has a potential of 2.5 to 3V vs. Li/Li+ at a lithium absorption/desorption and a spinel-type crystal structure.
