Excessive use of fossil fuels has caused serious resource depletion and environmental damage, exacerbating the gap between global energy demand and supply. Abundant and sustainable energy sources include biomass, hydropower, tidal power, solar power, and wind power. Large-scale energy storage technologies remain crucial to bridge the temporal gap between supply and demand, as they are intermittent and depend on weather and climate conditions. Although challenging, the development of sustainable energy sources is essential to ensure a continuous energy supply. Efficient methods for storing renewable and intermittent energy sources have attracted great interest in this field. Supercapacitors and batteries are two of the most promising electrochemical energy storage technologies due to their low maintenance requirements and high energy storage efficiency. Therefore, they have been widely used in energy storage applications from large to small scales so far. The electrode materials used mainly affect the charge storage capacity of EES devices.
