%X 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.
