Abstract The Li metal is an ideal anode material owing to its high theoretical specific capacity and low electrode potential. However, reactivity dendritic growth in carbonate-based electrolytes limit application. To address these issues, we propose a novel surface modification technique using heptafluorobutyric acid. In-situ spontaneous reaction between the organic acid generates lithiophilic interface of lithium heptafluorobutyrate for dendrite-free uniform deposition, which significantly...
Abstract Li metal has been attracting considerable attention as the most promising anode material for application in next‐generation rechargeable batteries. However, instability of formed solid electrolyte interphase (SEI) leads to a low coulombic efficiency (CE). Here, two kinds synthesized polymer materials with different molecular configurations (chain and cross‐linked), which are grafted skins on Cu foils (current collectors), reported. The interaction between polymers solvent reduces...
