Yadav, Gautam G. Turney, Damon Huang, Jinchao Wei, Xia Banerjee, Sanjoy Breaking the 2 V Barrier in Aqueous Zinc Chemistry: Creating 2.45 and 2.8 V MnO<sub>2</sub>–Zn Aqueous Batteries We report for the first time the creation of 2.45 and 2.8 V aqueous manganese dioxide (MnO<sub>2</sub>)|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 MnO<sub>2</sub>’s theoretical capacity (308 mAh/g) repeatedly for many cycles, thereby establishing this new MnO<sub>2</sub>|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. 2.8 V;MnO;Zn;Aqueous Zinc Chemistry;energy density characteristics;2.45;lithium-ion batteries;2 V Barrier;ion-selective membranes;manganese dioxide 2019-08-18
