Abstract
Ultracapacitor is a new way of storing electric energy eclipsing chemical batteries. Instead of storing energy electrochemically, it stores it in an electric field having a capacitance in series with an equivalent resistance. Ultracapacitors having multiple advantages over conventional batteries, including a lifetime of over 10 years, resistance to change in temperature, shock, overcharging and discharging efficiency makes it elite in the field of electronics .Eco-friendly, light in weight, no maintenance and low cost brings in an idea that it could be used for power production in satellites in space. Power production being important in satellite this paper reveals a way to store energy and utilise it to optimum level. The ultracapacitors can be charged using renewable solar energy and can be used in satellites for maximum energy requirements.
