Abstract: Flexible supercapacitors are being developed for powering flexible electronics for military and commercial applications. Graphene oxide dispersed in water has been used for inkjet printing the active electrode material onto metal film on Kapton current collectors. After printing, the graphene oxide was thermally reduced to produce conductive graphene electrodes. These electrodes were heat sealed together with added electrolyte and a polymer separator, and the resulting supercapacitor performance is good, with excellent capacitance retention with flexing demonstrated. A number of issues associated with using Kapton for packaging these devices have also been investigated.
