Power the growth.


The recent break-through by Rice University researchers in nano-tube development can be path breaking in the portable rechargeable battery segment. Before we discuss it, it is better if we go through batteries and their effectiveness in the perspective of the invention.

Batteries in the rechargeable segment come in three types. The Lead-Acid, Nickel- Cadmium and Lithium ion. All these three have something common. They store electrical energy in chemical form and this when required is taken for use. This is not like a capacitor where the energy is momentarily stored and the discharge rate can’t be brought to a minimal value to use it effectively. A capacitor is more suitable for instantaneous discharge whereas the battery works till there is enough chemical compound to continue the reaction and generate electricity. In all of them the process is reversible so that when electric current is supplied to the batteries they chemicals return to their original state and are ready for further electricity generation. The strength and ability of the batteries depend on the surface area of the electrodes and so most of the batteries have sheets rather than rods to do this.

In this situation the break through is important because this increases the surface by so many multiples that strength of the battery is increased infinite times. How? Rechargeable batteries work on the material present in the electrodes and more surface area present will increase the durability of the battery. So the seamless nanotubes of Carbon grown from the sheet of Carbon will provide an integral surface for the batteries. By conservative estimates this can have the lives of batteries increased by multiple times. Their benefits?

The first of them is in getting the interruptions between meetings eliminated. That too with the prized and valuable client. This is we are talking about the long distance internet conference in your tablet. The charging period will comparatively increase but not so much as the other.  The battery life is something that is one of the first steps to supercomputers that will draw lot of energy and this battery alone can fulfil some part of it. Rather than having a long rack of batteries for servers this can do it is combination of two or three batteries. Since all the growth of surface is in micro measurements the battery size also diminishes and space for it reduced substantially.

The batteries will not only serve the digital electronics as we know it but some other devices where the requirement is smaller and the drain intensity is also not that high. If they are used in combination then there are more possibilities with higher intensity. Getting batteries or power sources that support working continuously for infinite time is a real advantage to reap benefits. As world is more digitized and more electronics devices enter our lives it is natural that a heavy duty power source for them can give lot of good results.

Green initiative is another benefit this is going to give us. The cumbersome manufacturing processes are the only part to spoil any environment and there is enough time for the researchers to find a decent means of easy, cheap industrial process for commercial development of this battery. There will be time enough to hope that they will be cleaner by then to give us ultimate satisfaction.
