"adhesive electrode enabling components to work synergistically...  overcomes interfacial displacement... combined heteropolic acids (inorganic nano-sized clusters with fast and reversible redox activity enabling quick and reliable energy charge and discharge) with amino acids (help heteropolic acids become more flexible) and carbon materials (contribute to electronic conduction)... bridged gap between parallel electrodes by injecting gel-electrolyte... supercapacitors for high voltage output with metal-free interconnects"
