Embodiment Construction

[0031] Below in conjunction with the examples, the specific implementation of the present invention will be further described in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] A system for reducing TOC content in lithium battery raw materials includes a combined filtration system and an ultrafiltration subsystem, and the output end of the combined filtration system is connected to the input end of the ultrafiltration subsystem. The slurry prepared from lithium battery raw materials enters the joint filtration system, and after being filtered by the combined filtration system, it enters the ultrafiltration subsystem for filtration treatment, and then the lithium battery raw material slurry with very low TOC and other large particle impurities can be obtained.

[0033] Specifically, raw materials for lithium batteries include NiSO, which is required for the synthesis of lithi...

Abstract

The invention provides a system for reducing TOC content in a lithium battery raw material. The system comprises a combined filtration system for combining microcrystalline and active carbon for filtering and used for filtering an organic matter and a solid suspension in slip; and a ultrafiltration subsystem connected with an output terminal of the combined filtration system and used for filteringthe solid suspension in the slip. Compared with the prior art, the lithium battery raw material prepared by a hydrometallurgy can be directly used for preparing a lithium battery. The system providedby the invention can effectively reduce the TOC content in the lithium battery raw material and increases the lithium battery performance.

Description

technical field [0001] The invention relates to lithium battery production technology, and more particularly, to a system for reducing TOC content in lithium battery raw materials. Background technique [0002] Lithium battery mainly refers to a type of battery that uses lithium element as the main active material in the electrode material. Lithium batteries are light and durable, have relatively little pollution to the environment, and have excellent charge and discharge performance, and are widely used in the current battery field. [0003] In recent years, on the basis of the lithium element as the active material, a material composed of more than two elements has appeared as a battery active material, and among them, the research and application of the ternary material are better. For example, lithium, nickel, cobalt, manganese and other elements are combined into nickel-cobalt lithium manganate (chemical formula: Li(NiCoMn)O 2 ) of the ternary material. [0004] The ...
