Correlating hydrogen evolution and zinc deposition/dissolution kinetics to the cyclability of metallic zinc electrodes

Energy Environ. Sci., 2024, 17,1975-1983
DOI: 10.1039/D3EE04515C, Paper
Huijun Yang, Yang Yang, Wuhai Yang, Gang Wu, Ruijie Zhu
We correlate the Zn plating/stripping cyclability with the kinetics of hydrogen evolution. The pronounced hydrogen evolution kinetics and asymmetric Zn plating/stripping kinetics explain the poor Zn reversibility at low current density.
