Abstract

Small satellites, in particular microsatellites, have shown, in recent years, very advanced performances comparable to large satellites, especially in the field of remote sensing and scientific studies, and this with an affordable overall cost of production.

However, given the overall area available, these satellites have shown some limitations in their ability to support high power consumption demands. These demands come mainly from payloads, for example, Synthetic Aperture Radars (SAR) due to the constraint on the allowable weight and volume of the onboard battery pack.

During the last decades many research activities were coordinated to develop various environment friendly technologies. In addition to sustainable energy sources, efficient energy storage systems are needed. Amongst others high performance batteries and supercapacitors were developed to meet the need of efficient energy storage devices [2-6].

Recently, capacitors called supercapacitors have become a practical alternative energy storage device to batteries. These super capacitors have the ability to deliver high power at low weight and volume. They can store more energy than other capacitors, such as ceramic capacitors, tantalum capacitors, and aluminum electrolytic capacitors. They also have multiple charge/discharge capability and can operate in a wider temperature range. They have been applied to terrestrial applications which require multiple charge/discharge cycle tolerance and high peak input/output power capability [2-7].
