ABOUT Lithium Battery Raw Material Grinding Process & Solution
  Lithium battery cells are basically composed of positive electrodes, negative electrodes and separators. Lithium-ion battery materials and other types of battery materials are typical powder materials. Our goal is to help customers develop batteries with higher capacity, longer life, shorter charging time, lighter weight and smaller size. And this kind of high-performance battery has extremely high requirements on indicators such as particle size, purity, and morphology.

Through years of accumulated experience, Rucca can provide(Lithium Battery Raw Material Grinding Process & Solution)key equipment for the entire production line from raw material transportation, bag unpacking, storage, metering, dispersion, grinding to depolymerization for new energy companies. The main products focus on wet dispersing and grinding equipment andwholesystems, powder conveying and metering, high-viscosityglue mixing systems, powder surface modification equipment and ternary precursor co-precipitation reaction devices.

I.Wet Grinding Equipment
In battery industry,positive electrode materials (LMO, NMC, LFP…),negative electrode materials (LTO, silicon-based materials), ceramic-coated battery separators,are widely adopt wet grinding method.In application,the ion diffusion constant depends on particle size, with the diffusion rate in nanoparticles being much faster than in micron or bulk particles. However, the higher surface area can also lead to other undesirable effects, such as low packing density in the cathode and potential electrode/electrolyte reactions. Therefore, a narrower particle size distribution is required. Ruphân khốia M series vertical sand mill and N series nanoBEAD MILLcan meet the required particle size distribution.
II.Rucca Inline Dispersing System
It can realizetôinline dispersion ranging from low viscosity toonemillion cps,this tôinline dispersIng systemis the world's leading,dust-free feeding,highefficient and uniform dispersion. It is mainly used in the following aspects in the new energy industry:

1. For pre-dispersion of lithium iron phosphate cathode materials. It can automatically measure online and disperse without dust, and the dispersed particle size can reach 2 microns, which significantly improves the efficiency of the back-end sand mill;

(2)For the pre-mixing of conductive agents,the carbon nanotube conductive agent with 5% solid content can be premixed at one time to reduce dust pollution, disperse evenly, and significantly reduce moisture absorption;
III.Powder conveying and metering equipment:
It is mainly used for fast conveying and precise metering of positive and negative materials. It can be designed for batch metering, or used with online dispersion equipment for continuous metering.
IV.Powder surface modification equipment:
mainly used for surface coating of ternary materials. After melting, the surface modifier is uniformly dispersed on the surface of powder materials. Wet mixing can make the surface wettability better.
V.Ternary precursor reaction device:
Provide ternary precursor co-precipitation reaction device with precise control, high degree of automation, stable performance, uniform particle size and good morphology.
In the future, Ruphân khốia will continue to enter the forefront of technology, and provide more cost-effective equipment for the different grinding and dispersion requirements of the new energy industry to help customers achieve manufacturing upgrades.
