Abstract Zinc‐ion batteries (ZIBs) have been regarded as one of the most promising aqueous energy storage devices due to their low‐cost, high capacity, and intrinsic safety. However, relatively low Coulombic efficiency caused by dendrite formation side reactions greatly hinders rejuvenation ZIBs. Here, an utterly simple approach pencil drawing is employed improve poor performance normal Zn anode passivated byproduct well serious growth. Significantly, functional graphite layer can not only...
The solvation structure of Li+ in chemical prelithiation reagent plays a key role improving the low initial Coulombic efficiency (ICE) and poor cycle performance silicon-based materials. Nevertheless, agent is difficult to dope active anodes because their working voltage sluggish diffusion rate. By selecting lithium-arene complex with 4-methylbiphenyl as an anion ligand 2-methyltetrahydrofuran solvent, as-prepared micro-sized SiO/C anode can achieve ICE nearly 100%. Interestingly, best...
