Abstract [en]

Demands on the storage of energy have increased for many reasons, in part driven by householdphotovoltaics, electric grid balancing, along with portable and wearable electronics. These are fastgrowingand differentiated applications that need large volume and/or highly distributed electricalenergy storage, which then requires environmentally friendly, scalable and flexible materials andmanufacturing techniques. However, the limitations on current inorganic technologies have drivenresearch efforts to explore organic and carbon-based alternatives. Here, we report a conductingpolymer:cellulose composite that serves as the active material in supercapacitors which has beenincorporated into all-printed energy storage devices. These devices exhibit a specific capacitance of≈90 F g−1 and an excellent cyclability (>10 000 cycles). Further, a design concept coined ‘supercapacitorson demand’ is presented, which is based on a printing–cutting–folding procedure, thatprovides us with a flexible production protocol to manufacture supercapacitors with adaptableconfiguration and electrical characteristics.
