The present invention provides a process for making a battery cathode material with improved properties in lithium ion batteries. In one embodiment, the process comprises synthesizing a lithium metal polyanionic (LMP) powder. The process further comprises precipitating a carbonaceous coating on to the LMP powder to form a coated LMP powder. Additionally, the process comprises stabilizing and then carbonizing the coated LMP powder to produce the battery cathode material. The charge capacity, coulombic efficiency, and cycle life of the battery cathode material is better than those of the uncoated LMP powder.
L'invention porte sur un procédé de fabrication d~un matériau amélioré pour cathodes de batteries à ions lithium. Dans une exécution, le procédé consiste à synthétiser une poudre polyanionique de lithium, puis à précipiter un revêtement carboné sur la poudre, puis à stabiliser et carboniser la poudre pour obtenir la poudre revêtue. La capacité de charge, le rendement coulombien et la durée de vie dudit matériau cathodique pour batteries dépassent ceux des poudres non revêtues.
