(57) [Summary]n[Purpose] Large discharge capacity, high discharge operating voltage, good charging Non-aqueous secondary battery having discharge cycle characteristics and charging / discharging method I will provide a.n[Structure] The negative electrode active material is Lix MOj (where M is T Select from i, V, Mn, Co, Fe, Ni, Nb and Mo Represents at least one transition metal, and x is 0.1 7-11.25, and j is 1.6-4. In the range of 1), a lithium-containing transition metal acid represented by And the positive electrode active material is Li y NO z (However, N Represents at least one transition metal and At least one selected from Co, Mn, Ni, V and Fe Represents at least one transition metal, and y is 0.2 to 1.2, and z is in the range 1.4-3) Lithium-containing transition metal oxide represented, end of charge Use a non-aqueous secondary battery whose voltage is set to 3.5-4.7V In the discharge cycle, discharged to 0.5 to 1.5V Non-aqueous secondary battery that incorporates the method of charging later |
