Unlocking the Role of Indium Ions to Stabilize Zinc Negative Electrodes in Highly Acidic Electrolytes for High-Voltage Aqueous Zn Batteries
Key Points
The study aims to explore how indium ions can stabilize zinc negative electrodes in acidic environments to enhance battery performance.
Evaluation of zinc electrodes in various acidic electrolyte conditions
Comparison of performance with and without indium ions
Voltage output measurement in Zn||MnO2 and Zn||PbO2 battery systems
Inclusion of indium ions significantly improved voltage outputs up to ca. 2 V and 2.5 V respectively
High acidity allowed for better overall battery performance compared to near-neutral systems
Abstract
Operating Zn||MnO2 and Zn||PbO2 batteries in the highly acidic electrolytes enables much higher output voltages (up to ca. 2 V and 2.5 V, respectively) than the near-neutral systems, making them...
