Data related to the synthesis, characterization and electrochemical performance of high capacity sodium manganese periodate electrodes.

Sodium manganese periodate compounds were synthesized to serve as high capacity cathodes. The composition and morphology of resulting products were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray Diffraction (XRD) and thermogravimetric analysis (TGA). Composite cathodes made from the synthesized periodates were used to fabricate batteries with zinc anode and acetic acid electrolyte. Electrode formulations were optimized using nanocarbon conductive additives. For the full design and mechanism related to the sodium manganese periodate electrode with specific capacity as high as 750 mAh g-1, please refer to our research article "High Capacity Aqueous Periodate Batteries Featuring a Nine-Electron Transfer Process" [1].
