Cost-effective L-threonine additive in zinc metal batteries enables dendrite-free Zn deposition by modifying Zn2+ solvation structure, breaking hydrogen-bond networks, and forming protective adsorption layers, thereby improving cycling stability.
The in situ formed SEI by GOZIF8 altered the solvation process during Zn2+ ion deposion and induced the epitaxial deposition of Zn2+ along the (110) and (101) crystal planes to stabilize the reversibility of zinc anodes.
A scandium acetate electrolyte additive enables the improved stability of Zn metal anodes in an aqueous ZnSO4 electrolyte with suppressed side reactions and Zn dendrite formation due to the buffered pH value and homogenized Zn2+ distribution.
Reconstruction of Zn surfaces using BED and its dynamic adsorption–desorption behavior synergistically improve the stability of Zn anodes.
The unique functional groups and coordination environment of 3-thiophenecarboxylic acid (3TA) enable Zn2+ desolvation acceleration and protective layer formation, effectively suppressing dendrites, the HER, and corrosion for stabilized Zn anodes.
