Abstract
The present invention provides a non-aqueous electrolyte secondary cell in which charge/discharge property and energy density are significantly improved. The non-aqueous electrolyte secondary cell according to the present invention is provided with a positive electrode whose active material is Li(Ni.sub.1-y CO.sub.y).sub.1-z B.sub.z O.sub.2 (wherein y and z represent Ni, Co and B composition ratio which satisfies the relationships 0.1y.ltoreq.z<0.05y+0.026, y>0, and 0<z.ltoreq.0.03); a negative electrode capable of doping and de-doping lithium; and a non-aqueous electrolytic solution made from lithium salt dissolved or dispersed in a non-aqueous medium.
