PURPOSE:To provide a secondary battery by which energy density becomes high by high operation voltage and the cycle service life can be lengthened. CONSTITUTION:Lithium or a negative electrode material containing lithium and a positive electrode material expressed by a general equation LinMxZnyMnzO8 (provided that, M is Fe and/or Ni, and 0<n<=2, and x+y+z=4, and 0.2<=x<=0.6, and 0.2<=y<=0.6, and 2.8<=z<=3.2) are used. |
