摘要： The LiMPO4 compound is synthesized by reacting a compound of general formula XMPO4, nH2O where X represents a radical selected from —NH4 and —H and M is a transition metal selected from Co, Ni and Mn, with a lithium source such as lithium nitrate, at a temperature lower than or equal to 350° C. The XMPO4, nH2O compound further exhibits a particular morphology in the form of platelets that is preserved during the reaction between the two precursors. The LiMPO4 compound thus synthesized is advantageously used as active material of an electrode for a lithium storage battery.

摘要： The invention relates to a silicon/carbon composite material, to a method for the synthesis thereof and to the use of such a material. The silicon/carbon composite material is formed by an aggregate of silicon particles and of carbon particles, in which the silicon particles and the carbon particles are dispersed. The carbon particles are formed by at least three different carbon types, a first type of carbon being selected from among non-porous spherical graphites, a second type of carbon being selected from among non-spherical graphites and a third type of carbon being selected from among porous electronically-conductive carbons. The first and second carbon types each have a mean particle size ranging between 0.1 μm and 100 μm and the third carbon type has a mean particle size smaller than or equal to 100 nanometers.
