Probing the Effect of High Energy Ball Milling on the .

Particle size plays an important role in the electrochemical performance of cathodes for lithium-ion (Li-ion) batteries. High energy planetary ball milling of LiNi 1/3 Mn 1/3 Co 1/3 O 2 (NMC) cathode materials was investigated as a route to reduce the particle size and improve the electrochemical performance. The effect of ball milling times, milling speeds, and composition on the structure .

Effect of the Particle-Size Distribution on the .

The RP is first wet-milled to reduce the particle size, and then the particle-size distribution is measured via dynamic light scattering. This is followed by a dry-milling step to produce RP−graphite composites. We found that wet milling breaks apart the largest RP particles in the range of 2−10 μm, decreases the Dv90 from 1.85 to 1.26 .
