    摘要: A positive electrode includes a current collector and a positive electrode active material layer. The positive electrode active material layer includes a positive electrode active material including a core including a compound LiaCO1-bMbO2 and a surface-treatment layer. In the core compound, 0.95≦a≦1.1, 0.002≦b≦0.02, and M is one or more elements selected from the group consisting of Mg, Ca, Sr, Ba, Ra, Sc, Y, Ti, Zr, Hf, Rf, V, Nb, Ta, Db, Cr, Mo, W, Sg, Tc, Re, Bh, Fe, Ru, Os, Hs, Rh, Ir, Pd, Pt, Cu, Ag, Au, Zn, Cd, B, Al, Ga, In, Tl, Si, Ge, Sn, P, As, Sb, Bi, S, Se, Te, Po. The surface-treatment layer includes a compound including element of P, and one or more elements selected from the group consisting of Mg, Ca, Sr, Ba, Ra, Sc, Y, Ti, Zr, Hf, Rf, V, Nb, Ta, Db, Cr, Mo, W, Sg, Tc, Re, Bh, Fe, Ru, Os, Hs, Rh, Ir, Pd, Pt, Cu, Ag, Au, Zn, Cd, B, Al, Ga, In, Tl, Si, Ge, Sn, As, Sb, Bi, S, Se, Te, Po.
