The development of a novel battery comprising of high-oxidation-state periodate complex cathode and zinc anode is disclosed. A 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. NaMnIO6 double periodate salts were also synthesized from MnSO4 and NaIO4 using the same techniques. The H7Fe4(IO4)3O8 alone showed specific capacity of 300 mAh g−1; while NaMnIO6 showed specific capacity as high as 750 mAh g−1. Compared to single-electron processes in conventional cathode reactions, the possibility to significantly enhance cathode specific capacity via a multi-electron process associated with valence change from I(VII) to I2 is demonstrated. Novel 3D-printed reserve battery casing designs comprising replaceable electrodes also disclosed. Batteries featuring an ion-exchange membrane dual-electrolyte design are disclosed. Periodate based dry cell batteries utilizing polymer electrolytes are also disclosed.
