Mechanisms of Li deposition on graphite anodes: surface coverage and cluster growth
PublikacjaLi plating on the anode is a side reaction in Li-ion batteries which competes with Li intercalation and leads to loss of capacity. Growth of Li clusters into dendrites is a potential safety hazard for batteries which can lead to internal short-circuit and fires. We consider two possibilities of Li deposition on the surface of graphite anode: deposition of Li+ ions uniformly on the surface and deposition of clusters of metallic...
