Abstract
A non-aqueous electrolyte secondary battery in which it is possible to increase a capacity retention rate is provided. A non-aqueous electrolyte secondary battery is provided which includes: a positive electrode layer that includes a positive electrode active material and a conductive material; a negative electrode layer; and a non-aqueous electrolytic solution that is arranged between the positive electrode layer and the negative electrode layer, where an upper limit voltage is equal to or more than 4.5 V with respect to the oxidation-reduction potential of lithium, and the surface of the conductive material is coated with a coating layer mainly formed of P, O, C and H.
