PS, attributable to the presence of surface traps in fresh p-Si that reverse doping
effects. Graphene coating on PS has improved ~30X electrolyte–electrode interface
charge transfer resistance, ~15X Warburg diffusion resistance ~2X electrochemical
window, ~10–40X in both specific energy density and volumetric shown in Fig. 6 and
considerably enhanced long-term cycling characteristics with less than 1% change
in capacitance over 3500 cycles.
5 Conclusion
The energy storage devices can play a vital role in storing renewable energy for
technology applications in several fields. Different type of energy storage systems
with their characteristic parameter were reviewed. The silicon, due to its high theoretical specific capacity of ~4200 mAh/g and second most abundant element on the
planet, has been explored for energy storage devices. The PS that further provide
large surface area for electrode was discussed in detail. The surface of PS is highly
reactive with electrolyte and has high resistance. The coating of graphene on PS has
enhanced conductivity as well as provides a stable electrode–electrolyte interface
that is critical to attain decent energy storage characteristics. The PS with optimized
physical properties that include porosity, thickness, and morphology can provide the
potential toward integration of efficient energy storage into existent silicon-based
technology platforms in diverse technologies such as sensors, electronics, and solar
devices.
