NOVELTY - The non-aqueous electrolyte secondary battery comprises an anode, a cathode and non-aqueous electrolyte. The anode is lithium ion including occlusion and dischargable active material particles. The active material particles (10) contain secondary particles comprising several aggregated primary particles. The primary particles (12) contain lithium containing complex oxide. The active material particle is dotted with different metal oxide (13) other than lithium containing complex oxide between the primary particles.    USE - Non-aqueous electrolyte secondary battery is used as power supply for portable information terminal, portable electronic device, domestic electric power storage apparatus, two-wheeled motor vehicle and electric vehicle.    ADVANTAGE - The non-aqueous electrolyte secondary battery provides excellent safety during internal short circuit without inhibiting high-rate characteristics.    DETAILED DESCRIPTION - The non-aqueous electrolyte secondary battery comprises an anode, a cathode and non-aqueous electrolyte. The anode is lithium ion including occlusion and dischargable active material particles. The active material particles contain secondary particles comprising several aggregated primary particles. The primary particles contain lithium containing complex oxide. The active material particle is dotted with different metal oxide other than lithium containing complex oxide between the primary particles. The metal oxide is molybdenum, aluminum, titanium, manganese, calcium, magnesium, zirconium, tungsten, niobium and/or tin. The lithium containing complex oxide is of formula: LixNi1-y-zCoyMezO2. Where, x is 0.85-1.25, y is greater than 0-0.5, z is 0-0.5, sum of y and z is greater than 0-0.75 and element Me is aluminum, manganese, titanium, magnesium and/or calcium. An INDEPENDENT CLAIM is included for manufacture of active-material particles of non-aqueous electrolyte secondary battery.
