 The material's layered structure means that lithium ions from the battery's cathode move to the graphite anode and nestle between its layers when the battery charges. During discharge, these ions move back to the cathode, releasing energy in the process. Graphite also ensures the battery remains stable during charge and discharge cycles. Its structural ability helps maintain lithium battery's integrity, enabling longer battery life. The new facility will support the production of batteries for over 100,000 EVs a year.
