The present invention provides a non-aqueous electrolyte secondary cell with reduced degradation of the electrolytic solution or the anode active material and high cycle durability, and a method for manufacturing the same. The non-aqueous electrolyte secondary cell includes: a cathode capable of doping and de-doping lithium ions; an anode capable of occluding and releasing lithium ions, lithium or a lithium alloy; and an electrolytic solution containing an organic solvent, a lithium salt electrolyte and an additive. The cathode active material of the cathode contains a layered lithium-containing transition metal oxide of formula (1) Li 1.5 [Ni a Co b Mnc[Li] d ]O 3 ...(1) (where a, b, c, and d satisfy 0 < a < 1.4, 0 ‰¤ b < 1.4, 0 < c < 1.4, 0 < d ‰¤ 0.5, a + b + c + d = 1.5, and 1.0 ‰¤ a + b + c < 1.5), and a spinel phase present as a part thereof. The anode active material of the anode contains a carbon-based material with the surface fully or partly covered with a coating derived from the additive. |
