【 摘 要 】

tsWell-dispersed MXene nanosheets in the electrolyte dramatically shorten Zn2+ diffusion pathways and facilitate their migration.MXene interfacial layer with abundant functional groups and good conductivity induces uniform nucleation and enables long-term even deposition.MXene-containing electrolyte realizes dendrite-free Zn plating/striping with high Coulombic efficiency (99.7%) and superior reversibility (stably up to 1180 cycles).
