Mixed conductors of graphite, processes for their preparation and their use, notably for the production of electrodes for electrochemical generators, and new electrochemical generators

摘要

New mixed conductors resulting from the insertion of an alkali element in the lattice of an intercalation compound of graphite and of a product M'yXz : M' is a transition metal such as Ti, V, Cr, Mn, Fe, Mo; X is a non-metallic electronegative atom such as O, S, F, Cl or Br; y and z have the values of the indices in said product M'yXz. These mixed compounds are useful for the manufacture of positive electrodes of electrochemical generators.
