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.
