NOVELTY - A positive-electrode material (3) comprises first and second positive-electrode active materials, where first material has a composition of transition metal oxides of lithium, nickel, molybdenum/tungsten, and cobalt/cobalt and manganese; and second positive-electrode active material has a composition of transition metal oxides of lithium, nickel, titanium, and cobalt/cobalt and manganese. The percentage of first positive-electrode active material relative to sum of first positive-electrode active material and second positive-electrode active material is greater than or equal to 30% in mass ratio.    USE - As positive-electrode material used in lithium secondary battery (claimed) for plug-in hybrid car use.    ADVANTAGE - The positive-electrode material allows for achieving a high-capacity and high-safety lithium secondary battery required for the battery for the plug-in hybrid car use, and a high-capacity and high-safety lithium secondary battery. The positive-electrode material enhances the safety of battery by reducing the possibility that the battery can fall into ignition or burst when the battery temperature rises. The positive-electrode material implements the simultaneous compatibility between the enhancement in the discharge capacity and the significant reduction in the maximum heat-flow value. By using the positive electrode formed by coating the positive-electrode material as the positive-electrode plate of the lithium secondary battery, the high-capacity and high-safety lithium secondary battery can be obtained.    DETAILED DESCRIPTION - A positive-electrode material (3) (A1) comprises a first positive-electrode active material having a composition of formula (Li)1.1+x(Ni)a(M1)b(M2)cO2 (where M1 is molybdenum (Mo) or tungsten (W), M2 is cobalt (Co) or Co and manganese (Mn), x is -0.07-0.1, a is 0.7-0.98, b is 0.02-0.06, and c is 0-0.28), and a second positive-electrode active material having a composition of formula (Li)1.03+x(Ni)a(Ti)b(M3)cO2 (where M3 is Co, or Co and Mn, x is -0.03-0.07, a is 0.7-0.8, b is 0.05-0.1 and c is 0.1-0.25), where the percentage of first positive-electrode active material relative to sum of first positive-electrode active material and second positive-electrode active material is greater than or equal to 30% in mass ratio. When the second positive-electrode active material contains Co and Mn as M3, then the content of Co is greater than or equal to a content of Mn. An INDEPENDENT CLAIM is included for a lithium secondary battery (12), comprising a positive electrode capable of storing and releasing lithium; a negative electrode (4) capable of storing and releasing lithium; and separators (5), where the positive-electrode material (A1) is used for the positive electrode.
