Abstract

For sodium-ion battery, cathode properties of disodium rhodizonate, Na ₂C₆O₆, were investigated. Unlike other organic active materials, Na₂C₆O₆ exhibited good rechargeable capacity about 270 mAh g^-1, corresponding to more than 2 Na insertion per molecule between 1.0 and 2.9 V with using 1 M NaClO ₄/PC as electrolyte. Na₂C₆O₆ could also show the rechargeable capacity more than 90 mAh g^-1 even in acetylene black free pellets. The good cyclability was also confirmed in Na-ion cells with Na-predoped hard carbon anodes.
