OLIVINE STRUCTURE
Description of prior art:
Electrode materials with the olivine structure LiFePO4 (triphyllilte) and the quasi-isomorphous delithi~t~d material ClFePO4 have the advantage of an operating voltage of 3.5 V vs. Li+/Li~, i.e in the stability window of both liquid and polymer electrolytes with a flat discharge (lithium irltercalation) 10 plateau. The materials are however limited both by slow Li+ diffusion kinetics and low electronic conductivity. The absence of non-stoichiometry or mutual miscibility for both phases (LiFePO4 and [lFePO4) provides an explanation for these undesirable properties. The materials obtained by partial substitution of iron by manganese behave similarly.
Description of the invention:
15 In the present invention, the pristine olivine structure of LiMPO4 (M = Fe or Mn or their solid solutions) is modified either or both on the anionic and cationic! sites, by aliovalent or isocharge substitutions, to provide better lithium ion diffusitivity and electronic conductivity. For instance, these substitutions allows for the coexistence of iron or manganese in two different oxidation states in the same phase, or introduce specific interations with other elements having redox levels close to those of ~0 Fe and Mn (e.g.: Fe2+/Ti4+ ~ Fe3+/Ti3+, Mn2+/V5+ ~ Mn3+/V4+ etc.. ) both of which ar~
favorable to electronic conductivity, while disorder on the anionic site provides preferential diffusion sites for Li+. Along the sarne line, partial substitution of phosphorus by vanadium and to some extend by silicon, increases the lattice parameters, thus the size of the bottlenecks which tends to slow diffusion. The formation of non-stiochiometry domains with mixed valence states and/or transition-~5 metal mediated electron hopping as well as partial substitution of phosporus sites differentiates this new family of compounds from the LiFePO4/~FePO4 in which the totality of Fe (Mn) in either in the +II or +III oxidation state.
