LMFP CATHODE MATERIALS WITH IMPROVED ELECTROCHEMICAL PERFORMANCE

摘要

LMFP cathode materials are made in a mechanochemical/solid state process. The precursors are dried in a preliminary step to reduce the water content of the precursors of less than 1% by weight and preferably less than 0.25% by weight. The dried precursors are then dry milled and calcined to form particles of an olivine LMFP. The product has excellent specific capacity and capacity retention.
