Abstract:
A non-aqueous electrolyte secondary cell comprising:a cathode containing a lithium compound as a cathode active material; and an anode having an anode current collector containing Cu, and a material capable of doping/dedoping lithium as an anode active material; and a non-aqueous electrolyte; the cathode active material containing a lithium-nickel composite oxide with a mixture ratio A/(A+B) in the range from 0.2 to 1 wherein A is assumed to be the weight of the lithium-nickel composite oxide and B is assumed to be the total weight of the cathode active material other than the lithium-nickel composite oxide, and the anode active material having a specific surface in the range from 0.05 m2/g to 2 m2/g.
