Sodium mesoxalate as pre-sodiation agent for sodium-ion capacitors

Sodium-ion capacitors (SICs) face challenges due to the low first coulombic efficiency of disordered carbon anodes. This study explores sodium mesoxalate as a pre-sodiation agent, a sustainable solution to prevent sodium ion depletion. Integrated into the activated carbon positive electrode, it achieves irreversible oxidation at ~4.3 V vs. Na+/Na with a capacity of 331 mAh g⁻¹, enhancing SIC performance.

On the Selection of the Current Collector for Water Processed Activated Carbon Electrodes for Their Application in Electrochemical Capacitors

This study addresses the need for sustainable, water-processable alternatives in the manufacturing of electrodes for electrochemical energy storage, replacing hazardous fluorine compounds and toxic solvents. The research focuses on modified aluminium current collectors for high-mass loading activated carbon (AC) electrodes, evaluating their compatibility, processability, and electrochemical performance. Results show that carbon-coated aluminium significantly improves wetting properties, mechanical stability, and electrochemical efficiency, offering the best performance over time. This makes it the optimal choice for high-power electrochemical capacitors, aligning with sustainability and cost-efficiency goals.

Enhancing the stability of sodium-ion capacitors by introducing glyoxylic-acetal based electrolyte

This research presents a comprehensive comparison between a widely-used electrolyte (NaPF6 in EC) and a novel alternative (NaTFSI in TEG) for Sodium-ion Capacitors (#SICs). The results demonstrate the potential of the new electrolyte to significantly improve stability during float tests, offering a promising path for more durable and efficient SIC applications.
