The burgeoning demand for high-performance electrical energy storage has precipitated into the revival of research into lithium metal anode for battery systems. Traditional graphite-metal oxide systems are reaching their upper theoretical limits for capacity, with further improvements only resulting in incremental benefits. Consequently, the shift to lithium metal anode is inevitable for a major overhauling of battery performance. Lithium metal anodes are, however, fraught with undesirable electrodeposition. Based on the operating conditions and material properties, various morphologies are observed in experiments, including film, island, needle-like and fractal-like lithium electrodeposition. Amongst these, dendritic lithium morphology has the most deleterious consequences on battery safety and cyclability, which is still a critical challenge. This presentation aims to provide mesoscale insights into the fundamental understanding of lithium electrodeposition characteristics and electrochemistry-transport interactions.
