The invention provides a non-aqueous electrolyte secondary battery with improved high temperature recycling features and not reducing the battery content or load property. The invention provides an anode (11) having an anode active material absorbing or releasing lithium ion, a cathode (12) having a cathode active material absorbing or releasing lithium ion, and a non-aqueous electrolyte secondary battery (10), characterized in that the anode active material contains lithiumcobaltite A with magnesium evenly added based on 3mol% to 5mol% and lithiumcobaltite B with magnesium evenly added basedon 0.1mol% to 1mol%, which is combined by combination of A:B = 2:8 to 8:2.
