3. WHAT IS A PAPER BATTERY???

4. I NTRODUCTION  A paper battery acts as both a high energy battery and super capacitor, combining two components that are separate in traditional electronics.  This technology can be greatly utilized by medical devices.

5. P APER B ATTERY 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. . The nano materials are a one-dimensional structure with very small diameters. It is non toxic, environment friendly and is everything that a conventional battery is not.

6. C ONSTRUCTION CNT thin films were coated onto stainless steel substrates with a solution based process The concentration of CNT is 1.7mg/ml Add film with a thickness of 2 micrometer was formed after drying the CNT ink on the SS substrate at 80°C for 5 min. this film is then peeled off from substrate. These films as electrodes of paper battery. One films is pasted to electrolyte LTO(lithium titanium oxide) and the other film is pasted to electrolyte LCO(lithium cobalt oxide). Paper is sandwiched between two electrolytes LTO and LCO with PVDF (Poly vinili dine fluoride) acting as glue.

10. W ORKING  Internal operation of paper batteries is similar to that of conventional batteries with each battery generating about 1.5V.  If one can recall traditional batteries work in the manner where positive charged particles called ions and negative charged particles called electrons move between positive electrodes called anode and negative electrode called cathode. Current flows as electrons flow from anode to the cathode through the conductor, since the electrolyte is an insulator and doesn ’t provide a free path for electrons to travel.

12. W ORKING  Similarly in some paper batteries, carbon nanotubes act as cathode, the metal is the anode and paper is the separator.  Chemical reaction between metal and electrolyte results in production of ions whereas chemical reaction between carbon and electrolyte results in production of electrons. These electrons flow from the cathode to the anode through the external circuit.

13. APPLICATIONS

14. APPLICATIONS  Wearable Computers – One of the latest real time examples of wearable computers is Google Glass. It actually is a normal spectacle with an optical head mounted display and Glass is a computer in the form of a pair of eyeglasses and includes an optical head- mounted display which allows the user to use a smart phone.  It can be used for low power devices like calculators, wrist watches and wireless communication devices like mouse, Bluetooth headphones, keypads etc.

15. A DVANTAGES Paper battery function as a battery as well as a capacitor. Paper battery is a modern storage device with ultra-thin in size. Paper battery can generate electrical energy of 1.5V. Unlike the conventional battery , Paper battery can be used by folding , cutting and rolling. It has special properties such as more economical, biodegradable and Bio-compatible. The output voltage of this battery can be customized based on requirement.

16. L IMITATIONS The carbon nano-tubes used in this battery are very expensive. The paper battery wastage may damage lungs if it inhaled. The e-wastage is generated by paper batteries.

17. F UTURE S COPE  It holds great potential to advance capabilities in portable power design for applications ranging from bioinstrumentation to consumer electronics and even large power systems served by conventional batteries.  The paper like qualities of the material make it especially attractive for energy storage in medically implanted devices (for example, a pacemaker, insulin pump or the implantable radio chip).

18. C ONCLUSION  A paper battery is a paper like device formed by the combination of carbon nanotubes and a conventional sheet of cellulose-based paper which act as a flexible ultra-thin energy storage and energy production device.  As this technology is adapted it will prove to be extremely useful and could even save not only cost but lives also.
