Summary on Grant Application Form
Supercapacitors are remarkably simple electrochemical devices, containing (in the uncharged state) 2 identical electrodes and an electrolyte, and are characterised by high capacitance (up to > 1 F), in marked contrast to conventional capacitors (pF-mF). The maximum operating voltage (per cell) of a supercapacitor is determined by the electrochemical stability of the electrolyte (commonly a liquid), giving a practical limits of 1 V for hydrated systems.The programme involves an original design concept: an all-solid-state device employing hydrated thin solid films (a 'green chemistry' approach) will result in low volume/high power density at ambient temperature. The capacitor is to be faradaic (as opposed to double layer) in its operation, with intercalation/deintercalation of protons into/from the electrodes. The programme develops redox-composited polymer electrodes to be used with proton-conducting polymer electrolytes. In one approach the composited polymer electrode is supported on carbon paper (with MEAs produced by hot-pressing), while in a second the screen printing of electrode pastes/inks onto polymer electrolyte films is employed.The programme uses a full range of sophisticated electrochemical and materials development/characterisation techniques, and is to be pursued in collaboration with an industrial partner which is well placed to advise on, and implement, ultimate commercial exploitation of new energy storage technology.
