This study presents a lithium electroplating technology designed to enhance the quality of lithium anodes for next-generation lithium metal batteries. We investigate the electroplating process to achieve a high-density lithium layer. By employing atmospheric-pressure plasma treatment on copper current collectors and applying uniaxial pressure during the electroplating process, significant progress was made in improving the properties of the electrodeposited lithium. Furthermore, we analyze the factors contributing to performance degradation at low E/C ratios (electrolyte-to-capacity ratio) and discuss strategies for the commercialization of electroplated lithium as anode material for lithium metal batteries.
