Abstract

An antimony based anode material for a rechargeable battery comprises nanoparticles of composition SbMOwhere M is a further element selected from the group consisting of Sn, Ni, Cu, In, Al, Ge, Pb, Bi, Fe, Co, Ga, with 0≦x<2 and 0≦y≦2.5+2x. The nanoparticles form a substantially monodisperse ensemble with an average size not exceeding a value of 30 nm and by a size deviation not exceeding 15%. A method for preparing the antimony based anode material is carried out in situ in a non-aqueous solvent and starts by reacting an antimony salt and an organometallic amide reactant and oleylamine.
