Claim Text:
1. An electrode material for a lithium-ion battery comprising a porous agglomeration of particles, the particles being formed by heating, under reducing conditions, from submicron powder of a transition metal oxide, and comprising cores of stoichiometric transition metal oxide surrounded by a shell of an under stoichiometric oxide of the transition metal, wherein the porous agglomerate has pores having sizes in the range from 1 nm to 1 μm, and further wherein the pores within the porous agglomerate comprise a bimodal pore distribution with at least first pores in the size range from 1 nm to 50 nm and at least second pores in the size range from 50 nm to 1 μm, said sizes being the diameters of spheres of equivalent volume to the respective pores.
