Paper Battery

In this paper the use of self-rechargeble paper thin film batteries, their performance and applications has been presented. The Glucose activated paper battery based on glucose oxidised enzyme using a simple and cheap plastic laminating technology has been demonstrated. The enzyme and glucose concentration can be optimized to gear up the power requirement. Ultra fast all polymer paper based batteries are an option with some short comings yet such as low cycling stabilities and functional discharge rate. Also integration secondary battery with the paper battery is also shown to improve the power.

A paper battery is a flexible, ultra-thin energy storage and production device formed by combining carbon nanotube 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.

Paper batteries may be folded, cut or otherwise shaped for different applications without any loss of integrity or efficiency . Cutting one in half halves its energy production. Stacking them multiplies power output. Early prototypes of the device are able to produce 2.5 volt s of electricity from a sample the size of a postage stamp.

The devices are formed by combining cellulose with an infusion of aligned carbon nanotubes that are each approximately one millionth of a centimetre thick. The carbon is what gives the batteries their black colour.

Cellulose based paper is a natural abundant material, biodegradable, light, and recyclable with a well-known consolidated manufacturing process. Here, we expect to contribute to the first step of an incoming disruptive concept related to the production of self-sustained paper electronic systems where the power supply is integrated in the electronic circuits to fabricate fully self sustained disposable, flexible, low cost and low electrical consumption systems such as tags, games or displays.

Polymer based paper battery

Now we try to replace the metal/metal oxide with polymer. In this process, the preparation of novel redox polymer and electronically conducting polymer-based electrode materials is essential. While it has recently been shown that it is possible to manufacture redox polymer based electrodes and batteries with high-capacities and very good cycling performances, the corresponding development within the field of electronically conducting polymers is ongoing. Conducting polymers are particularly interesting materials as devices based on these materials could be used as adaptable energy storage devices due to their inherent fast redox switching, high conductivity, mechanical flexibility, low weight and possibility to be

integrated into existing production processes. While conductive polymers are more environmentally friendly and cost-efficient than most metal containing electrode materials, the insufficient cycle stabilities and the high self-discharge rates have so far been limiting their applicability in commercial battery systems.
