Unlike batteries, which store energy through chemical reactions, supercapacitors store energy electrostatically, enabling rapid charge/discharge cycles. In certain applications, this gives them a significant advantage in terms of power density, lifespan, efficiency, operating temperature range and sustainability.
The future of supercapacitors and batteries lies in their collaboration and integration as researchers work on hybrid energy storage systems that combine both technologies' strengths. These systems will offer high energy density from batteries and high power density from supercapacitors, providing the best of both worlds.
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.
Commercial lithium-ion batteries are widely used to power electric vehicles due to their high energy density, but supercapacitors are increasingly finding applications in the automotive and transportation industries.
The most important thing to know about supercapacitors is that they offer the same general characteristics as capacitors, but can provide many times the energy storage and energy delivery of the classic design. Supercapacitors offer many advantages over, for example, lithium-ion batteries.
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.
