Abstract

See full text

A method for preparing a high-performance single-crystal layered cathode material of formula LiNixTM1-xO2 (0.60.66TMO2 (TM=one or more of Ni, Mn, Fe, Cr, and Co). Stoichiometric amounts of transition-metal salts are mixed to form a transition metal salt solution. A precipitating agent is added to the transition metal salt solution followed by co-precipitating a mixed transition metal precipitant. The mixed transition metal precipitant is mixed with a lithium precursor or a sodium precursor to form a cathode material precursor mixture. The cathode material precursor mixture is subjected to various calcining and grinding processes followed by annealing to create single crystal layered cathode material particles.
