Selection of new energy storage solutions for high-performance power applications using supercapacitors？

              Supercapacitors have characteristics such as high power density and energy density, long service life, and compact size. When combined with other emerging battery technologies, they can meet the needs of high-performance power applications.

Nowadays, performance and reliability are essential for every design, and for engineers, energy storage has always been a fatal weakness in their designs. In the past, the solution for backup power was batteries, mainly lead-acid batteries. Nowadays, engineers have more options to meet the demand for backup power, including advanced battery technologies such as lithium-ion and nickel hydrogen batteries, fuel cells, solar cells, and double-layer capacitors.

Lithium ion supercapacitors have made significant progress in providing reliable energy storage solutions. They have been applied in many designs and solved many cost issues in the past, but design engineers still face the same problem as when using lead-acid batteries, that is, all of these technologies are based on chemical reactions, their service life is limited and restricted by temperature, and the demand for high current will directly affect their service life. Therefore, these battery technologies still face some challenges in terms of durability and reliable applications.

        Fuel cells are a newly emerging and very attractive battery technology that is gradually entering many applications, and there has been a lot of promotion for them recently. The ultimate application field of fuel cells is in automobiles, but during the transition period, they have already appeared in the backup power market. The key issues in using fuel cells as backup and main power sources are the start-up time and dynamic power response of these batteries. Although fuel cells have excellent energy density, their dynamic power is low, so they require an enhancement technology for power assistance and start-up. There are also supercapacitors, also known as electrochemical double-layer capacitors (EDLC). Compared with electrolytic capacitors, supercapacitors have very high power density and substantial energy density. These devices have been applied in many fields such as consumer electronics, industry, and automobiles.

Supercapacitors are ultra-high power devices with a power density of up to 20kW/kg, although their energy is still only a small fraction of that of batteries. The size of supercapacitors is very compact (small supercapacitors are usually only the size of stamps or smaller), but they can store much more energy than traditional capacitors, and the discharge speed can be fast or slow. They have a very long lifespan and can be designed for the entire lifecycle of end products. When combined with supercapacitor technology, high-energy batteries and/or fuel cells can achieve high power characteristics and long working life.

            The structure of supercapacitors is very similar to that of electrolytic capacitors or batteries, with the main difference being the use of different electrode materials. In supercapacitors, the electrodes are based on carbon material technology, which can provide a very large surface area. The large surface area and small charge spacing give supercapacitors a high energy density. The capacity of most supercapacitors is calibrated in Farads (F), typically between 1F and 5000F.

Supercapacitors can replace batteries or serve as smaller economical batteries. The equivalent series resistance (ESR) of supercapacitors is very small, which can provide and absorb very large currents; It adopts a "mechanical" rather than a chemical charge carrier mechanism, thus having a long and predictable service life, and its performance changes are also smaller over time. These features can benefit applications such as regenerative braking and other products that require fast charging, such as toys and tools.
