Résumé
This paper presents an exhaustive study of the Li-Zn-P system through the synthesis and electrochemical characterisation of several binary and ternary phases: Lig(9)ZnP(4), LiZnP, Zn3P2 (alpha and beta), ZnP2 (alpha and beta), LiZn, and LiZn4. Three synthetic routes have been used to prepare these materials: ceramic synthesis and ball milling without and with annealing. Li-Zn-P system phases have been evaluated through X-ray diffraction and electrochemical reactivity towards lithium. Exhibiting high specific capacities at potentials close to 0.7 V vs. Li+/Li, some of these materials are promising as negative electrode materials for lithium ion battery.
