Abstract

We designed and fabricated supercapacitors by directly drawing graphite on cellulose paper. The supercapacitors show stable long cycling performance and a high areal capacitance of 2.3 mF cm−2, which is much higher than the literature reported values. This solvent-free deposition technique represents a low cost, highly scalable and versatile fabrication method for integrated paper-based energy devices.
