摘要： Disclosed is a positive electrode active material for a lithium ion secondary battery, including lithium-transition metal composite oxide of a layer crystal structure, in which the lithium-transition metal composite oxide contains an element that improves conductivity of electrons in the lithium-transition metal composite oxide. Use of this positive electrode active material can improve cycle characteristics, high rate characteristics and thermal stability of lithium ion secondary batteries. Furthermore, by use of this positive electrode active material, gas generation in batteries can be decreased.

摘要： Disclosed is a positive electrode active material for a nonaqueous electrolyte secondary battery having at least a lithium-transition metal composite oxide of a layer structure, in which an existence ratio of at least one selected from the group consisting of elements which may become tetravalent and magnesium is 20% or more on a surface of the lithium-transition metal composite oxide. By use of this positive electrode active material, a nonaqueous electrolyte secondary battery having excellent battery characteristics, specifically, having excellent high rate characteristics, cycle characteristics, low-temperature characteristics, thermal stability, and the like, under the even more harsh environment for use can be realized.
