Vanillin: An Effective Additive to Improve the Longevity of Zn Metal Anode in a 30 m ZnCl2 Electrolyte

Zn Metal BatteriesDesigning effective aqueous electrolytes for zinc metal anodes remains a challenge. In article number 2301712, P. Alex Greaney, Xiulei Ji and co‐workers show that adding a few ppm vanillin to 30 m ZnCl2 enhances the anode's reversibility, prevents dendrite formation, and boost...

Zusammenfassung:Zn Metal BatteriesDesigning effective aqueous electrolytes for zinc metal anodes remains a challenge. In article number 2301712, P. Alex Greaney, Xiulei Ji and co‐workers show that adding a few ppm vanillin to 30 m ZnCl2 enhances the anode's reversibility, prevents dendrite formation, and boosts Coulombic efficiency. This electrolyte results in a Zn metal battery with an N/P ratio of 2 that retains stable cycling over 800 cycles.
