Abstract
We present the development of a novel battery comprising iron(III) periodate complex cathode and zinc anode. The periodate complex [H7Fe4(IO4)3O8] was prepared by a precipitation reaction between Fe(NO3)3 and NaIO4 and was used in battery development for the first time. The periodate complex along with 14% carbon nanotubes and a polytetrafluoroethylene coating formed a stable flexible electrode, and the battery showed specific capacity as high as 300 mA h g-1. Compared to single-electron processes in conventional cathode reactions, the possibility to significantly enhancing the cathode specific capacity via a multielectron process associated with valence change from I(VII) to I2 is demonstrated. A novel three-dimensional printed reserve battery design comprising replaceable electrodes and acetic acid electrolyte is also presented.
