“…[80] Since then, multiple studies have exploited the beneficial influence of Ag. [94][95][96] In fact, the lithiophilicity of Ag nanoparticles was confirmed independently of the electrolyte composition, hence suggesting the application in AFSSB. Similarly, transferring further successful CC modification approaches such as carbon-based wetting agents (e.g., g-C 3 N 4 , [97] Graphene [77] ) or 3D structures (e.g., Au-modified carbon fibers, [98] graphene cages [99] ) from liquid electrolyte batteries to AFSSB is regarded to be highly promising.…”

“…In addition, Wondimkun et al also reported the lipophilicity properties of the hybrid electrode (Cu|Ag@PDA‐GO) by the two‐step spin‐coated methods (Figure 6g). [ 78 ] The functional material was designed on the current collector surface to reduce the Li nucleation barrier, which enables higher 55.7% capacity retention after 60 cycles within the FEC in the carbonate‐based electrolyte at 0.5 mA cm −2 (Figure 6h,i). Lithiophilic silver nanoparticles with polydopamine (Ag@PDA) were crucial as nucleation seeds to facilitate the uniformity of the initial lithium nucleation by forming an alloy LiAg phase, which could maximize the utilization of the limited lithium inventory for plating and stripping.…”

The anode‐free lithium metal batteries (AF‐LMB), eliminating the use of host anode, can exploit the full potential of the lithium‐containing cathode system in terms of the highest retrievable gravimetric/volumetric energy densities, simplified processing of the anode coating, as well as the reduced cost of cell production and maintenance. However, the issues of interfacial contact resistance, curtailed ion pathway, as well as the dead lithium formation coherently lead to the unsatisfactory cation utilization upon repetitive cycling, which impairs the performance endurance of the practical relevance. Hitherto, a plethora of optimization strategies for the electrolyte and deposition substrate are proposed to extend the cell lifespan. Most of the methods, however, are still based on empirical attempts and lack of systematic diagnosis tools to elucidate the interplay between the structural evolution of the cathode and Li deposition behavior. Herein, the recent research process is summarized and the current development dilemma from multiple perspectives is probed, aiming to highlight the key features of the system that dedicate the cycling endurance. In addition, prospects of the operando characterizations that can be used to accelerate the mechanism elucidation of the AF‐LMB configuration are systematically commented.

“…[ 35 ] As dendrites are grown on the anode surface, parasitic SEI damage is inevitably accompanied by the morphological change of metallic deposits, thereby substantially reducing Coulombic efficiency. Thus, building an artificial SEI layer on the metal anodes [ 37 ] or current collectors [ 38 ] has been emphasized as a smart strategy to restrain dendrite growth and further prevent catastrophic side reactions at the SEI/electrolyte interface. Such artificial SEI layers accommodate the morphological changes of anode surface and assist regular redeposition of metal underneath the SEI layers, thus effectively protecting fresh metal surface to the electrolyte.…”

“…Modulating the interface of current collectors with polymeric artificial SEI layers has also been proposed as an effective strategy for dendrite suppression. [ 38 ] Weng et al. have demonstrated that an ultrathin (<100 nm) ionomer membrane consisting of Li‐exchanged sulfonated polyether ether ketone (SPEEK‐Li) embedded with polyhedral oligosilsesquioxane (POSS) on a copper current collector can achieve stable Li plating‐stripping cycles in a carbonate‐based electrolyte (see Figure 3b).…”

[ 38b ] The SPEEK exchanged by Li + exhibits high ionic conductivity and mechanical stability, while the case‐like POSS serves as a reinforcing filler. Li‐ions diffuse across the SPEEK‐Li/POSS cation‐selective membrane to form uniform and dense Li deposits.…”

Metal batteries have been emerging as next‐generation battery systems by virtue of ultrahigh theoretical specific capacities and low reduction potentials of metallic anodes. However, significant concerns regarding the uncontrolled metallic dendrite growth accompanied by safety hazards and short lifespan have impeded practical applications of metal batteries. Although a great deal of effort has been pursued to highlight the thermodynamic origin of dendrite growth and a variety of experimental methodologies for dendrite suppression, the roles of polymer materials in suppressing the dendrite growth have been underestimated. This review aims to give a state‐of‐the‐art overview of contemporary dendrite‐suppressing polymer materials from the electro‐chemo‐mechanical viewpoint of macromolecular design, including i) homogeneous distribution of metal ion flux, ii) mechanical blocking of metal dendrites, iii) tailoring polymer structures, and iv) modulating the physical configuration of polymer membranes. Judiciously tailoring electro‐chemo‐mechanical properties of polymer materials provides virtually unlimited opportunities to afford safe and high‐performance metal battery systems by resolving problematic dendrite issues. Transforming these rational design strategies into building dendrite‐suppressing polymer materials and exploiting them towards polymer electrolytes, separators, and coating materials hold the key to realizing safe, dendrite‐free, and long‐lasting metal battery systems.
