Description

technical field

[0001] The invention relates to a carboxylic acid compound, its preparation method and application. Background technique

[0002] In recent years, with the rapid development and promotion of electric vehicles, the demand for lithium-ion batteries has also continued to expand. Nickel-cobalt-manganese ternary cathode material has good cycle performance, stable structure, and high cost performance. It is a new type of lithium-ion battery cathode material, and the main raw materials of the precursor product of ternary cathode material are nickel salt, cobalt salt, and manganese salt.

[0003] Cobalt is mostly accompanied by nickel, and most of them appear at the same time in minerals, such as in nickel laterite ore. In many industries, waste residues containing valuable metals such as nickel and cobalt will be produced, such as waste power battery materials, waste residues containing nickel and cobalt, waste catalysts, etc. Most of these waste residues also cont...
