Abstract :
Aluminium collector electrodes, formed by the plasma-spraying method, have been developed for high-performance electric double-layer capacitors. The capacitors consist of activated carbon-fiber (ACF) cloth for polarizable electrodes, conductive aluminium layers for collector electrodes, a separator, and an organic electrolytic solution. Aluminium electrode layers formed by the plasma-spraying method showed low-electric-resistance effective electrical contact to the activated carbon-fiber cloth, and electrochemical stability in the electrolytic solution, which resulted in high-performance capacitors with low inner resistance and high capacitance.<>
