The invention relates to an electrode material and a composite electrode including same. The electrode material consists of particles or particulate aggregates of a complex Li<SUB>i</SUB>M<SUB>m</SUB>M'<SUB>m'</SUB>Z<SUB>z</SUB>O<SUB>o</SUB>N<SUB>n</SUB>F<SUB>f</SUB> oxide, wherein M is at least one transition metal, M' is at least one metal other than a transition metal; Z is at least one non-metal; coefficients i, m, m', z, o, n and f are selected in such a way that the complex oxide is electrically neutral, with i = 0, m > 0, z = 0, m' =0, o > 0, n = 0 and f = 0. At least part of the complex oxide particle or particulate aggregate surface is coated with a carbon layer bound by chemical bonds and/or physical bonds to the carbon. The complex oxide has formula; the carbon has covalently bonded functional GF groups. |
