The life expectancy of ESs is much longer than batteries despite of the fast redox reactions that are involved at the time of charging and recharging which serves as another advantage of long life in case of supercapacitors [33]. ESs having ability to maintain high capacitance, also bear the ability to be recharged and attain native
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.
