Abstract
Abstract For sodium-ion battery, cathode properties of disodium rhodizonate, Na 2 C 6 O 6 , were investigated. Unlike other organic active materials, Na 2 C 6 O 6 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. Na 2 C 6 O 6 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.
