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.
