Designing Electrode Structure of Lithium Metal Anode in Cell Perspective for Practical Application

The development of high-energy-density batteries has been expedited for the application of large-scale devices such as electric vehicle and aircraft toward world electrification. To meet required specification, lithium metal batteries have been emerged to substitute typical Lithium-ion batteries, widely adopted as energy storage system throughout electric system owing to the potential of Lithium metal anode (LMA), featuring considerable theoretical capacity. However, chronic issues, evolving consecutive dendritic growth during electrochemical reaction, make LMA remain challenging and therefore various researches have been suggested to mitigate electrochemical degradation at electrode level. Furthermore, to ultimately realize stable battery system, deploying LMA, the perspective should be focused on cell level beyond material or electrode level. In here, comprehensive approaches for rational structure of LMA have been reviewed to suggest the key design factors for practical application.
