A leading lithium-ion battery cathode material manufacturer in Xiamen was looking for a jet mill to produce the Lithium Cobalt Oxide (LiCoO₂, or LCO) powder while maintaining high production efficiency and product purity. LCO is a critical material for high-energy-density batteries used in consumer electronics and electric vehicles. The customer required a reliable solution to produce powder with precise particle size distribution to enhance battery performance, including improved capacity, stability, and rate capability.
The customer needed to grind LCO to an ultra-fine level with D99 ≤ 6μm (meaning 99% of particles below 6 microns) to optimize electrochemical properties and ensure uniform coating in battery production. Previous equipment struggled with contamination risks, low yield, and inconsistent particle size distribution. Additionally, LCO’s sensitivity to oxidation and moisture demanded a contamination-free, low-heat grinding process. They aimed for a stable production capacity of 700kg/h to meet growing demand in the new energy sector. Our client is highly satisfied with the seamless operation of the jet mill, which continues to provide a reliable and steady production yield, exceeding their expectations.
