Global organisation
Most prominently, solar, wind, geothermal, and tidal energy harvesters generate electricity in today's life. As the world endeavors to transition towards renewable energy sources, the role of supercapacitors becomes increasingly pivotal in facilitating efficient energy storage and management.
Supercapacitors as energy storage could be selected for different applications by considering characteristics such as energy density, power density, Coulombic efficiency, charging and discharging duration cycle life, lifetime, operating temperature, environment friendliness, and cost.
Achieving a long-life cycle for supercapacitor remains a challenging target in certain situations. Energy harvesting and conservation are essential for all kinds of power sources, particularly renewable energy sources, given their global distribution.
In this configuration, the PV array serves as the primary power source, while the supercapacitor functions as the energy storage device mitigating uncertainties in both steady and transient states . The incorporation of a supercapacitor in this system enhances power response, improving both power quality and efficiency.
Scaling up production and reducing manufacturing costs to compete with traditional energy storage technologies pose challenges for the widespread adoption of supercapacitors, requiring innovations in synthesis, processing, and manufacturing techniques.
Furthermore, supercapacitors-based energy storage subsystem should consider the nonlinearity of supercapacitors such as leakage, residual energy, topology, energy density, and charge redistribution to charge the supercapacitors efficiently.
