Harmonized Multifaceted Zinc Deposition Enabled by Amine‐Functionalized Carbon Quantum Dots for Dendrite‐Free Zinc Anodes Under Ultrahigh Current Densities

Carbon Energy, EarlyView.
A novel multifaceted Zn2+ deposition along the native crystal planes of Zn foil has been developed using NH2‐CDs electrolyte additives. This approach overcomes the inability of the conventional (002)‐facet deposition strategy to suppress Zn dendrites at high current densities, achieving dendrite‐free Zn anodes at an ultrahigh current density of 100 mA ...

Synergistically Accelerating Zn2+ Transport and Desolvation Through Cation‐Deficient Ion Channels in High‐Performance Zn Metal Batteries

Carbon Energy, EarlyView.
The novel ITO protective layer enables ultra‐stable Zn metal anodes. By synergistically accelerating Zn2+ desolvation and Zn2+ transport via its unique structure, the ITO layer suppresses dendrites and side reactions. This results in exceptional stability for over 6000 h at 2 mA cm–2 and stable operation in Zn ||MnO2 full‐cell configurations.
