Abstract

Linvention concerne la production d'un matériau de cathode dite « avancée », incorporant du phosphate ferrique lithié LiFePO4 (LFP) de morphologie micrométrique, préparé en utilisant différents grades d'acide phosphorique comme matière première comprenant divers microéléments métalliques et/ou métalloïdiques, respectivement cationique et/ou anioniques, sélectionnés parmi Na, S, F, Mg, Zn, et K, Cl, Al, Ca, Co, Cr, Fe, K, Mn, Mo, Ni, Ti, V, Cd et As notamment. Ces microéléments sont soit issus des matières premières utilisées, soit incorporés aux divers réactifs mis en oeuvre au cours du procédé.
