PAPER BATTERY
[attachment=41029]
INTRODUCTION
A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotubes with a conventional sheet of cellulose-based paper. A paper battery acts as both a high-energy battery and supercapacitor , combining two components that are separate in traditional electronics . This combination allows the battery to provide both long-term, steady power production and bursts of energy. Non-toxic, flexible paper batteries have the potential to power the next generation of electronics, medical devices and hybrid vehicles, allowing for radical new designs and medical technologies.
Battery chemistry
Battery Chemistry Electrochemical reaction - a chemical reaction between elements which creates electrons. Oxidation occurs on the metals (“electrodes”), which creates the electrons. Electrons are transferred down the pile via the saltwater paper (the “electrolyte”). A charge is introduced at one pole, which builds as it moves down the pile.
Development
The creation of this unique nanocomposite paper drew from a diverse pool of disciplines, requiring expertise in materials science, energy storage, and chemistry. In August 2007, a research team at Rensselaer Polytechnic Institute (led by Drs. Robert Linhardt, the Ann and John H. Broadbent Senior Constellation Professor of Biocatalysis and Metabolic Engineering at Rensselaer; Pulickel M. Ajayan, professor of materials science and engineering; and Omkaram Nalamasu, professor of chemistry with a joint appointment in materials science and engineering) developed the paper battery
CONCLUSION
This energy storage device is cost-effective because the device can be able to be used in the smallest and most diversly designed electronics. Such as cell phones, mp3 players and medical equipment. The reasearchers say that it can also be used in automobiles and aircraft. But it has a poor processibility, being that it is particularly insoluble of infuseble. Lastly, the use of ionic liquid makes the device environmentally friendly; a major concern in nanotechnology.
