Abstract

See full text

A method for preparing an electrode material, said material comprising complex oxide particles having a non-powdery conductive carbon deposit on at least part of their surface, said method comprising: grinding into nanometer size complex oxide particles or particles of complex oxide precursors, wherein the grinding is performed in a bead mill on particles dispersed in a carrier solvent, adding an organic carbon precursor to the oxide particles or oxide precursor particles before, during or after said grinding, and pyrolysing the mixture thus obtained, selecting the size of the particles to grind, the size of the beads used to grind, and the size of the resulting particles such that: 0.004
