The present invention proposes a kind of preparation method of the nickelic ternary lithium battery material of polythiophene base, using lithium salts, nickel salt, cobalt salt, manganese salt as raw material, then lye is added, nickel cobalt manganese precipitates, sintering obtains nickelic ternary basic material, then thiophene monomer and dispersion is added, after ultrasonic disperse, strong oxidizer is added during high speed dispersion, thiophene monomer is oxidatively polymerized into polythiophene, and polythiophene complex microsphere is collectively formed with nickel cobalt manganese, the nickelic ternary material of high solidity is obtained after being then spray-dried.The present invention overcomes existing nickelic ternary materials to recycle defect that is unstable, being mixed with reduction density, reduce conductivity, it polymerize the guiding to form microballoon polythiophene by thiophene monomer, nickelic ternary material is set to form microballoon, microstructure change has been firmly fixed, the compacted density for improving nickle cobalt lithium manganate, efficiently solves the high temperature of nickel-cobalt lithium manganate cathode material lithium battery, overcharges, the safety under Condition of Acupuncture. |
