A glucose activated paper battery has been developed by the team of researchers which is based on glucose oxidized enzyme by using a simple and cheap plastic laminating technology. In order to gear up the power requirement, this enzyme and glucose concentration can be optimized. These batteries are based on ultra fast polymer but they have some short comings such as low cycling stabilities as well as functional discharge rate.
According to the team of researchers, it also includes integration secondary battery in order to improve the power. This paper battery is flexible as well as ultra thin energy storage and production device which is formed by the combining carbon nano-tube along with a conventional sheet of the cellulose based paper. It has the ability to act both the high energy battery and super capacitor by combining two components which are separate in the traditional electronics.
Through this combination, these batteries are able to provide long term, steady power along with production and bursts of energy. They are non-toxic as well as flexible paper batteries which have the potential to power the next generation of electronics, medical devices and hybrid devices which can allow for the radical new designs and medical technologies.
According to the researchers, these paper batteries can be folded, cut or shaped for the several applications without any kind of loss of integrity or efficiency. Cutting the one in half halves its energy production while stacking them can multiply the power output. The previous prototypes of the device by the researchers are able to produce 2.5 volts of the electricity from the sample size of the postage stamp.
These devices have been formed by combining the cellulose with the infusion of the aligned carbon nano-tubes which are approximately one millionth of the centimeter thick. The batteries are black because of this carbon. The cellulose battery is the natural material, biodegradable as well as light and recyclable in order to contribute to the first step of the incoming disruptive concept which are related to the production of self sustained paper electronics systems and where the power supply is integrated in the electronics circuits in order to fabricate fully self sustained disposable, flexible, low cost and finally low electrical consumption systems like tags, games and displays.
Now the researchers are trying to replace the metal with polymer for which the preparation of novel polymer as well as electronically conducting polymer based electrode materials are essential. It has been shown by the researchers that it is possible in order to make polymer based electrodes as well as batteries with high capacity and very well cycling performances.
