Probing the Effect of High Energy Ball Milling on the

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 and properties of NMC cathodes was determined.
