The practical use of supercapacitor devices is hindered by their low energy density. Here, we briefly review the factors that influence the energy density of supercapacitors. Furthermore, possible pathways for enhancing the energy density via improving capacitance and working voltage are discussed.
What is the difference between a supercapacitor and a battery?
Their reduced energy density in comparison to batteries is one of the primary problems. Supercapacitors usually have an energy density of 5–10 Wh/kg, which limits their use in applications that need long-term energy storage. Batteries, on the other hand, can reach energy densities of up to 265 Wh/kg .
Why are supercapacitors not widely used?
Despite their benefits, supercapacitors have several problems that prevent them from being widely utilized. Their reduced energy density in comparison to batteries is one of the primary problems. Supercapacitors usually have an energy density of 5–10 Wh/kg, which limits their use in applications that need long-term energy storage.
