摘要

A secondary battery includes: a cathode; an anode; and an electrolytic solution. The anode includes a lithium composite oxide represented by following Formula (1), LiwZnxSnyMzO4  (1) where M is one or more of Co, Mg, Ni, Ca, Al, Ti, V, Cr, Mn, Fe, Cu, and Ag; and w to z satisfy 0.3≦̸w≦̸1, 0.3≦̸x≦̸1, 0.8≦̸y≦̸1.2, and (w+x+y+z)=3.
