Unlike batteries, supercapacitors charge in seconds and can withstand nearly unlimited charge cycles. Supercapacitors have higher energy density than traditional capacitors but lower energy density than standard batteries used in electronics such as Internet of Things devices.Compared with other capacitors, 3V 5F supercapacitor can store and release energy very quickly. This feature makes it widely used in electric vehicles and new energy applications.
