How conductive paper can be used for energy storage?

The intrinsic properties of paper, such as high solvent absorption and strong binding with nanomaterials, allow easy and scalable coating procedures. Taking advantage of the mature paper technology, low cost, light and high-performance energy-storage devices are realized by using conductive paper as current collectors and electrodes.

How to measure sheet resistance of conductive paper?

The sheet resistance of conductive paper was measured by using the four-point probe technique (EDTM). To make silver nanowire (Ag NW) ink, Ag NWs were produced in solution phase following the method of Xia and colleagues ( 45 ).

Can graphene-based energy storage devices be commercially viable?

Future research could explore optimizing the pore structure and scaling the process for industrial applications, potentially advancing the commercial viability of graphene-based energy storage devices. To create a laser-induced graphene sheet, a commercial Kapton film was utilized.

Can conductive paper be used as a current collector?

Moreover, the sheet resistance of the conductive paper decreased from ≈60 Ω/sq down to 9 Ω/sq after soaking in the organic electrolyte, which might be due to the dissolution of surfactant or hole doping of CNTs ( 44 ). On the device level, batteries with CNT conductive paper as current collectors were cycled 500 times, as shown in Fig. 5 C.

What are the mechanical properties of conductive paper?

The conductive paper also has excellent mechanical properties. The conductive paper with CNT thicknesses from 100 nm to 5 μm can be bent down to a 2-mm radius ( Fig. 2 C) or folded without any measurable change in electrical conductivity.
