Supercapacitors, as energy storage devices, require high power density, long cycle life, and fast charging and discharging capabilities. Although lithium-ion batteries have high energy storage density, they have a short cycle life and pose safety risks. In contrast, supercapacitors are more suitable for applications with frequent charging and discharging, but have lower energy storage capacity. It may be necessary to combine both or choose a suitable supercapacitor model, such as double-layer capacitors or pseudocapacitive capacitors, to ensure sufficient energy storage capacity to meet nighttime lighting needs.Specification
