3D printing of high-performance micro-supercapacitors with patterned exfoliated graphene/carbon nanotube/silver nanowire electrodes
Micro-supercapacitors (MSCs) show great potential as on-chip energy storage devices for portable electronics. The major flaw of thin-film MSCs is their low energy density. To improve the energy density, thicker electrodes are required. However, the fabrication of MSCs with thick electrodes remains a...

| description | Micro-supercapacitors (MSCs) show great potential as on-chip energy storage devices for portable electronics. The major flaw of thin-film MSCs is their low energy density. To improve the energy density, thicker electrodes are required. However, the fabrication of MSCs with thick electrodes remains a challenge. In this work, a novel 3D printing method is employed to fabricate high-performance MSCs with interdigitated exfoliated graphene (EG)/carbon nanotube (CNT)/silver nanowire (AgNW) electrodes. The nanowelding of AgNW junction plays a critical role in the realization of 3D printing. To enhance the electrochemical performances of EG, phosphorus atoms are incorporated into the carbon framework with 1.7 at%. The areal capacitance of the 3D printed MSC is 21.6 mF cm
