The impact of milling time and rotation speed on Li-NMC cathode performance

The Impact of Milling Time and Rotation Speed on Li-NMC Cathode Performance. Technological developments of electrical energy storage on this era are batteries. Many electronic devices using battery for energy storage, so the batteries in the future will be a strategic and economical source of energy storage. Li-ion battery comprises of anode, cathode and separator. The cathode is fully functional in the process of transferring lithium ions, during the charging and discharging processes. The particle size has a significant part within the electrochemical performance of the cathode for Li-ion battery. Milling could be a way to decrease particle size and improve electrochemical performance. Milling is a method that use the collision energy between grinding balls and the walls of the container (jar milling). X- rays characteristics are analytical signals that used in electron microscopy for chemical analysis. The results showed that longer milling time and a faster rotation speed, will give smaller size which increased the electrochemical performance of the battery cathode.
