    摘要: According to one embodiment, a nonaqueous electrolyte battery is provided. A positive electrode contains a lithium-nickel-cobalt-manganese complex oxide represented by the formula Li1+aNi1-b-cCobMncO2. A negative electrode contains at least one selected from a lithium titanate having a spinel structure and a monoclinic β-type titanium complex oxide. The negative electrode further contains at least one selected from an oxide which has a spinel structure and represented by the formula AFe2O4 and an oxide which has a spinel structure and represented by the formula ACo2O4. A ratio of the total mass of AFe2O4 and ACo2O4 to the total mass of the negative electrode active material is in a range from 1% by mass to 5% by mass.

    摘要: 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.
