Electrical energy is an indispensable resource for contemporary society, and the advantages and disadvantages of energy storage equipment directly affect the full application of power equipment. In recent years, with the extensive development and use of portable devices, uninterruptible power supply systems, and electric vehicles, the use of batteries has been increasing. Rechargeable batteries, especially lead-acid batteries, are widely used in various industries due to their low price, stable performance, and no memory function. However, the battery is subject to its innate conditions, and there are problems of poor cycle life, poor high and low temperature performance, sensitive charging and discharging process, difficulty in recovery of deep discharge performance capacity, and environmental pollution. Traditional batteries have become increasingly unable to meet people's energy storage systems. The requirements provide a broad space for the development of supercapacitor batteries.
Supercapacitor battery (Electrical Double-Layer Capacitor) is a new type of energy storage device, which has the characteristics of short charging time, long service life, good temperature characteristics, energy saving and environmental protection.
