4. Description

Super capacitors are a practical solution for storage of electricity and transportation from on end to other end replacing the chemical batteries. But there are several challenges like, choosing of appropriate dielectric material and synthesis of semi conductor devices are important challenges. The proposed method is an effort towards solving the needs of electricity based automobiles, mobiles and other tablet kind of electronic devices which need very quick recharge and long storage without loss of stored electricity. Lithium ion batteries though appear to solver the limitations of electro chemical batteries, the challenges involved in scaling up encourages adaption of super capacitors.

Background of invention

A capacitor is an energy storage medium similar to an electrochemical battery. Most batteries, while able to store a large amount of energy are relatively inefficient in comparison to other energy solutions such as fossil fuels. It is often said that a 1kg electrochemical battery is able to produce much less energy than 1 litre of gasoline; but this kind of comparison is extremely vague, mathematically illogical, and should be ignored. In fact, some electrochemical batteries can be relatively efficient, but that doesn't get around the primary limiting factor in batteries replacing fossil fuels in commercial and industrial applications (for example, transportation); charge time.

Supercapacitors, also known as ultracapacitors, are able to hold hundreds of times the amount of electrical charge as standard capacitors, and are therefore suitable as a replacement for electrochemical batteries in many industrial and commercial applications. Supercapacitors also work in very low temperatures; a situation that can prevent many types of electrochemical batteries from working. For these reasons, supercapacitors are already being used in emergency radios and flashlights, where energy can be produced kinetically (by winding a handle, for example) and then stored in a supercapacitor for the device to use.

A conventional capacitor is made up of two layers of conductive materials (eventually becoming positively and negatively charged) separated by an insulator. What dictates the amount of charge a capacitor can hold is the surface area of the conductors, the distance between the two conductors and also the dielectric constant of the insulator. Supercapacitors are slightly different in the. fact that they do not contain a solid insulator.
