Architecture design principles for stable electrodeposition behavior-towards better alkali metal (Li/Na/K) anodes

Recent advances in dendrite-free lithium metal anodes for high-performance batteries

“…The most widespread mechanism of formation of lithium dendrites is mainly based on Chazalviel's physical model. [27][28][29][30] As shown in Fig. 1, when electrode polarization is carried out below the critical current density, the lithium anode surface is not susceptible to lithium dendrite growth as the ion concentration near the lithium anode is close to the concentration of the bulk electrolyte.…”

Advances in Nanofibrous Materials for Stable Lithium-Metal Anodes

“…Moreover, the thickness of the SEI layer and the internal resistance of the battery increase sharply, and the battery capacity is seriously lost. The above series of reactions eventually lead to problems such as electrode structure collapse and battery disconnection. − …”

Precise Control of Li+ Directed Transport via Electronegative Polymer Brushes on Polyolefin Separators for Dendrite‐Free Lithium Deposition

“…[22] For instance, increasing the concentration of salts could endow high current density and improve the transference number of cations, thus expediting ion diffusion and prolonging the nucleation time of dendrites. [9] However, the mechanism and composition of electrolyte-derived SEI remain controversial and is not very controllable, respectively. [23] In order to facilely achieve tunable structure and composition, the interfacial engineering of both artificial SEI layers and separators at the anode/electrolyte interface, including conductive alloy layers, [6,24] lithophilicrich organic components, [25] and their hybrids, [26,27] have been applied to stabilize the Li anode by redistributing Li + flux and providing fast ion diffusion.…”
