Supercapacitors – A Viable Alternative to Lithium-Ion
While a Supercapacitor with the same weight as a battery can hold more power, its Watts / Kg (Power Density) is up to 10 times better than lithium-ion batteries. However, Supercapacitors'' inability to slowly discharge implies its Watt-hours / Kg (Energy Density) is a fraction of what a Lithium-ion battery offers.
Supercapacitors have been used in electronic devices to meet the requirements of rapid charging/discharging, such as for memory back-up, and uninterruptible power supply (UPS). Also, their use is being extended to transportation and large industry applications that require high power/energy density, such as for electric vehicles and power ...
