They can be charged and discharged very quickly, offer excellent cycle life, long operational life, and operate over a broad temperature range. The major drawbacks of supercapacitors are low energy density and a high self-discharge rate. Supercapacitors do not require a solid dielectric layer between the two. . This paper reviews the research progress of supercapacitors (SCs), including the influence of electrode materials on energy storage mechanism and performance, and life prediction. However, by carefully managing voltage, temperature, and other stress. . As with any other energy storage component, many variables in the surrounding environment can adversely afect the components' ability to store energy when designing systems with supercapacitors. Some of these variables may be in the system designer's control, while others may not.
