The invention relates to binary, ternary and
quaternary lithium phosphates of general formula Li(FexM<1>yM<2>z)PO4 wherein M<1 >represents at least one element of the group comprising Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Be, Mg, Ca, Sr, Ba, Al, Zr, and La; M<2 >represents at least one element of the group comprising Sc, Ti, V, Cr, Mn, Co, Ni, Cu, Zn, Be, Mg, Ca, Sr, Ba, Al, Zr, and La; x=between 0.5 and 1, y=between 0 and 0.5, z=between 0 and 0.5, provided that x+y+z=1, or x=0, y =1 and z=0. The said
lithium phosphates can be obtained according to a method whereby precursor compounds of elements Li, Fe, M<1 >and / or M<2 >are precipitated from aqueous solutions and the
precipitation product is dried in an
inert gas
atmosphere or a
reducing atmosphere at a temperature which is between
room temperature and approximately 200° C. and tempered at a temperature of between 300° C. and 1000° C. The inventive
lithium phosphates have a very high capacity when used as
cathode material in lithium accumulators.
