NOVELTY - Non-aqueous electrolyte batteries comprises positive electrode (6) which has active material containing lithium nickel cobalt manganese metal oxide whose pore volume is 0.03-0.15 ml/g, pore surface area is 2.8-4.8 m2/g, and porosity of 16-28% which are measured by mercury intrusion technique, negative electrode (7) which has titanium-containing compound whose pore volume is 0.08-0.2 ml/g, pore surface area is 5.5-7.5 m2/g, and porosity is 18-30% which are measured by mercury intrusion technique, and exterior component which accommodates positive electrode and negative electrode.    USE - A non-aqueous electrolyte batteries for battery pack (claimed). Uses include but not limited to power supplies of digital camera and vehicle-mounted uses, such as electric vehicle, four-wheel hybrid electric vehicle, and two-wheel or four-wheel assist bicycle.    ADVANTAGE - The non-aqueous electrolyte battery and battery pack have excellent in input-output characteristics.    DETAILED DESCRIPTION - Non-aqueous electrolyte batteries comprises positive electrode which has active material containing lithium nickel cobalt manganese metal oxide of formula Li1-xNi1-a-b-cCoaMnbM1cO2 whose pore volume is 0.03-0.15 ml/g, pore surface area is 2.8-4.8 m2/g, and porosity of 16-28% which are measured by mercury intrusion technique, negative electrode which has titanium-containing compound whose pore volume is 0.08-0.2 ml/g, pore surface area is 5.5-7.5 m2/g, and porosity is 18-30% which are measured by mercury intrusion technique, and exterior component which accommodates positive electrode and negative electrode. Pore volume, pore surface area, and porosity of the positive electrode are smaller than those of the negative electrode.
