Breaking the 2 V Barrier in Aqueous Zinc Chemistry: Creating 2.45 and 2.8 V MnO2–Zn Aqueous Batteries
Source abstract
Abstract
We report for the first time the creation of 2.45 and 2.8 V aqueous manganese dioxide (MnO2)|zinc (Zn) batteries without the use of expensive ion-selective membranes separating the anodes and cathodes. This new high-voltage aqueous battery (HiVAB) is able to charge and discharge 20–100% of MnO2’s theoretical capacity (308 mAh/g) repeatedly for many cycles, thereby establishing this new MnO2|Zn battery as the forerunner for the possible replacement of lithium-ion batteries for applications where cost, safety, and energy density characteristics are considered paramount.
