By repeating the impregnation steps, the researchers obtained a conductive paper and then added alternating layers of metal oxide energy storage materials, such as manganese oxide, to it. Regarding this process, Lee stated that it is basically a very simple process, where we alternate operations in a beaker to provide a good conformal coating for cellulose fibers. In this way, we can fold the obtained metal paper without damaging its conductivity.

Researchers have shown that their self-assembly technology has improved paper supercapacitors. According to tests, the maximum power and energy density of the metal paper supercapacitor are 15.1mW/cm2 and 267.3uW/cm2, respectively, which are basically higher than traditional paper or textile supercapacitors.

It is worth noting that in this study, researchers used gold nanoparticles because the material particles were easy to use, but they planned to use cheaper metals such as silver or copper to reduce material costs.

Although this study involves small paper samples, based on the technical requirements of the solution in practical applications, researchers suggest that larger storage tanks or even spraying techniques can be used to amplify their use. Regarding this technology, Lee also added that we have implemented nanoscale control over the coating applied to paper, and if we increase the number of layers, performance will continue to increase.

Next, the research team will test the technology on flexible fabrics and develop flexible batteries that can be used in conjunction with supercapacitors.
