A paper battery is engineered to use a spacer formed largely of cellulose (the major constituent of paper). It incorporates nanoscopic scale structures to act as high surface-area electrodes to improve conductivity.
A Paper battery consists mainly of carbon and paper; it can be used to power pacemakers within the body. A paper battery can be used both as a capacitor and battery. It is an ultra-thin storage device. It is biodegradable, non-toxic, bio-compatible, and economical.
In Automobiles and Aircraft: • in Hybrid Car batteries • in Long Air Flights reducing Refueling • for Lightweight guided missiles • for powering electronic devices in Satellite programs 4. PAPER BATTERY: INDIAN SCENARIO, Unfortunately, not much work has been carried out in India, except for a few notable ones.
Broadbent, Pulickel M. Ajayan, Omkaram Nalamasu with a joint meeting in Material Science and engineering developed the Paper Battery, which is also known as Nano Composite Paper. In December 2009, Yi Cui and his team at Stanford University successfully made an actual prototype that gave a terminal voltage of 1.5 V.
- Step 1: Take a cellulose-based paper and apply black carbon ink to it.
- Step2: Spread this ink applied on the paper.
- Step3: After spreading ink, laminate a thin film over the cellulose surface.
- Step4: Heat the cellulose paper for 5min at 80 degrees C.
The battery configuration was assembled in an Argon filled glove box. The CNT-microfiber paper, coated with lithium titanium oxide (LTO) and lithium cobalt oxide (LCO), was cut in circular samples with a diameter of 0.58 cm, which form the anode and cathode of the developed battery.
