Abstract
A battery capable of improving load characteristics, low-temperature characteristics and high-temperature cycle characteristics is provided. A cathode () includes a lithium cobalt complex oxide represented by LiCoMIMIIO(MI includes at least one kind selected from the group consisting of Al, Cr, V, Mn and Fe, MII includes at least one kind selected from the group consisting of Mg and Ca, 0.9≦a≦1.1, 0.9≦x<1, 0.001≦y≦0.05, 0.001≦z≦0.05, x+y+z=1), and further includes Zr as a sub-component element. The content of Zr is within a range from 0.01 mol % to 10 mol % both inclusive as a ratio (Zr/Co) of Zr to Co in the lithium cobalt complex oxide.
