Additional information
Renewable energy sources lack security of supply and fuel cells and batteries do not exhibit high power densities. The electrochemical supercapacitor is highly topical, with high power, and studied at Surrey under the EPSRC Energy Storage Consortium. Hybrid supercapacitors offer high oxide-based specific capacitances but have involved thin oxide films and low device-based energy densities. We highlight use of phase pure birnessite MnO2 in a variety of nanostructured morphologies in thick film supercapacitor electrodes; hybrid supercapacitor cells then have high specific capacitance, raised energy density and durable cyclability.
