“…There have been a few reports on single crystal Cu substrates: one study reports that Cu [100] has the lowest energy barrier for nucleating lithium, resulting in non-dendritic lithium particles, 104 while other groups have reported that Cu[111] also yields nondendritic lithium particles. 105,106 One possible explanation for the difference in conclusions regarding the superior Cu plane is that different lithium growth mechanisms may be dominating on the two planes. In any case, it is clear that more understanding is needed on the role that crystallographic orientation plays in Li deposition morphology.…”

“…Another approach to improving the efficiency of the plating–stripping is modifying the current collector. Liu et al [ 133 ] investigated the homogeneity of lithium plating–stripping in LMBs using LiPF 6 /EC:DMC electrolyte and employing modified Cu substrates with (111)‐preferred orientation and (111)‐nanotwinned lamella grains. They reported a significant improvement in the CE and cycling stability.…”

Li‐ion batteries (LIBs) have been widely used in portable electronic devices, the transportation sector, and grid storage. However, LIB anodes are restricted to carbon‐based materials limiting their energy density. Recently, the use of metallic Li as the anode in Li‐metal (LMBs) and solid‐state (LMSSBs) batteries has gained attention due to the high energy densities it can provide. Herein, the research progress in the field to derive a broad picture of the technologies relying on Li metal as the anode is critically assessed. It is essential to understand the Li plating and stripping processes in terms of fundamental electrochemical and physical mechanisms to address the challenges of employing metallic Li. Anode‐free Li‐metal batteries (AFLMBs) and anode‐free solid‐state batteries (AFSSBs) are the most attractive systems discussed in this review. AFLMBs are highly studied, but safety concerns due to Li dendrite growth and side reactions between plated Li metal and liquid electrolyte are some key challenges yet to be resolved. AFSSBs are the ultimate goal in this field, as utilizing a solid‐state electrolyte (SSE) can prevent dendrites at moderate charging rates and realize the potential of the anode‐free battery. However, the general problems with the use of SSEs remain and require substantial research efforts.
