Supercapacitors, bridging conventional capacitors and batteries, promise efficient energy storage. Yet, challenges hamper widespread adoption. This review assesses energy density limits, costs, materials, and scalability barriers.
As a result, commercially available supercapacitors typically exhibit energy densities ranging from 1 to 10 Wh/kg, significantly lower than lithium-ion batteries (100–265 Wh/kg), . The energy density (Wh/kg) and power density (kW/kg) of supercapacitors are compared with lithium-ion batteries and lead-acid batteries in Fig. 5.
Supercapacitors (SCs) feature high power density and low energy density, allowing rapid charge/discharge cycles. They boast minimal internal resistance (ESR), prolonged storage life, and extended operational lifetimes.
Their recyclability and extended lifespan compared to batteries make them environmentally advantageous. Despite their numerous advantages, the primary limitation of supercapacitors is their relatively lower energy density of 5–20 Wh/kg, which is about 20 to 40 times lower than that of lithium-ion batteries (100–265 Wh/Kg) .
