Resumo
The development of green and biodegradable electrical
components is one of the main fronts of research to overcome the growing
ecological problem related to the issue of electronic waste. At the same time,
such devices are highly desirable in biomedical applications such as integrated
bioelectronics, for which biocompatibility is also required. Supercapacitors for
storage of electrochemical energy, designed only with biodegradable organic
matter would contemplate both aspects, that is, they would be ecologically
harmless after their service lifetime and would be an important component for
applications in biomedical engineering. By means of atomistic simulations of
molecular dynamics, we propose a supercapacitor whose electrodes are
formed exclusively by self-organizing peptides and whose electrolyte is a green
amino acid ionic liquid. Our results indicate that this supercapacitor has a high
potential for energy storage with superior performance than conventional
supercapacitors. In particular its capacity to store energy was estimated to be
almost 20 times greater than an analogue one of planar metallic electrodes.
