Abstract

An electrode material for a lithium-ion battery comprises a porous agglomeration of particles, the particles being formed from nanopowder of a transition metal oxide and comprising cores of stoichiometric transition metal oxide surrounded by under stoichiometric oxide of the transition metal. Also described and claimed are the use of a corresponding material in a lithium ion battery and a method of making such an electrode.
