    摘要: A nonaqueous electrolyte battery includes a positive electrode, a negative electrode and a nonaqueous electrolyte. The positive electrode contains active material particles and a coating material. The active material particles are represented by any one of the following formulae (1) to (3) and have an average particle diameter of 0.1 to 10 μm. The coating material comprises at least particles having an average particle diameter of 60 nm or less or layers having an average thickness of 60 nm or less. The particles or the layers contain at least one element selected from the group consisting of Mg, Ti, Zr, Ba, B and C. LixM1yO2  (1) LizM22wO4  (2) LisM3tPO4  (3)

    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.
