Jet mill is an indispensable equipment in the preparation of lithium cobalt oxide

In lithium-ion batteries, the cathode material is the most important component, and it is also the key to determining the performance of lithium-ion batteries. Lithium cobaltate, lithium vanadium phosphate and lithium iron phosphate have been widely used as cathode materials. Among them, lithium cobalt oxide has an average output voltage of 3.7V, an energy density of up to 140mAh/g, and has the advantages of good cycle performance and thermal stability. These advantages make lithium cobalt oxide considered the most potential high-voltage battery cathode material. The preparation and processing of lithium cobalt oxide powder is also related to the quality of subsequent products, so in the preparation of lithium cobalt oxide, the selection of ultra-fine grinding and classification equipment is particularly important.

Ultra-fine grinding and classification is an indispensable item for lithium cobalt oxide processing, and it is also the back-end equipment of all processing procedures, which has an important effect on the quality of the finished lithium cobalt oxide powder. For the ultra-fine pulverization and classification of lithium cobalt oxide, a jet mill is usually used to make the processed finished product have the characteristics of fine particle size, uniform particle size distribution, good dispersibility, and pollution-free.

Equipment characteristics of lithium cobalt oxide jet mill:

• It has the ability of shaping, and can control the particle morphology and particle size. The finished product has excellent particle morphology and can be used for shaping of different material characteristics and requirements.
• The particle size distribution is narrow, and the finished product has a high tap density.
• Over-grinding is low, and the finished product rate can reach over 96%.
• The equipment is lined with wear-resistant materials, the equipment wears little, and the finished product has high purity.
• Using frequency converter for precise control, the material fineness can be adjusted arbitrarily between 0.5-100 μm.
• Full negative pressure operation, low noise, no dust pollution.

Lithium cobalt oxide jet mill is also suitable for lithium battery cathode materials: iron phosphate, lithium iron phosphate, ternary materials, lithium manganate, lithium nickel manganate, lithium carbonate, lithium hydroxide, ferrous oxalate and other dry powder materials Crushing, breaking and particle shaping.
