Abstract

The invention discloses a method for preparing a nickel-cobalt-manganese ternary material precursor. By virtue of the method, waste small-particle-size nickel-cobalt-manganese ternary material precursors in a product are separated out and recycled into a reaction kettle, so that the ternary material precursors with the particle size of 7-15 micro meters account for over 95% in the product.

Description

technical field

[0001] The invention relates to the technical field of lithium-ion battery cathode materials, in particular to a preparation method of a spherical nickel-cobalt lithium manganese oxide cathode material precursor. Background technique

[0002] Lithium-ion batteries are widely used in many fields such as mobile phones, digital cameras, computers, and electric vehicles because of their high energy, long service life, and low pollution. Among them, the cathode material occupies the most important position in the lithium-ion battery structure, and its performance directly determines the performance of the final product lithium-ion battery, and the performance and price of the cathode material will directly affect the performance and price of the lithium-ion battery .

[0003] At present, layered lithium cobalt oxide, spinel lithium manganese oxide, lithium iron phosphate, layered nickel cobalt lithium manganese oxide, etc. are mainly used as positive electrode ma...
