Sodium sulfonate groups substituted anthraquinone as an organic cathode for potassium batteries

Sodium sulfonate groups substituted anthraquinone as an organic cathode for potassium batteries
Sodium sulfonate groups substituted anthraquinone was successfully tested as an organic positive electrode material in potassium batteries. As an organic cathode material, enhanced electrochemical performance was demonstrated for anthraquinone-1,5-disulfonic acid sodium salt, notably a good cycling stability and a capacity retention of 78mAhg−1 after 100cycles. The findings offer an effective way to develop high performance organic electrode materials for potassium batteries.
