Diffusion Limited Current Density: A Watershed in Electrodeposition of Lithium Metal Anode

Xieyu Xu et al.

Summary: This study investigates the diffusion limited current density (DLCD) as the threshold for electrodeposition of lithium (Li) metal. It finds that uniform electrodeposition can be achieved when the applied current density is below the DLCD. Non-uniform electrodeposition leads to preferential deposition of Li metal within broken solid electrolyte interphases and increased consumption of active Li. Thus, lowering the current density or increasing the DLCD are proposed as strategies for uniform electrodeposition and stable interfaces of Li metal.
