Paper battery, an introduction
A paper battery is an energy storage device. It is used as a battery and also as a good capacitor. It is formed by combining two things which are carbon nano tube and the cellulose based paper.
Definition of Paper battery
Paper Batteries are made using a combination of nano tubes made from carbon and paper made from cellulose. The process to make paper batteries start with making a cathode and anode from manganese dioxide and zinc. These are then printed onto the cellulose paper. The nanotubes made from carbon are then added. The electrolyte is an ion based liquid solution.
Working of Paper battery
Once the paper is immersed in the ion based liquid solution, there is a chemical based reaction between the liquid and the electrodes, in this case the nanotubes. The electrons
which are generated move from the cathode to the anode to generate electricity. The best way to increase the output is to stack different paper batteries, one over the other.
Use of paper battery
Paper battery advantages
- It has a paper thin sheet of cellulose and it is infused with the carbon nanotubes. It is acting as a electrodes. And it also acts as a good conductor storage device.
- It provides long steady power by functions as a superconductor and a lithium iron battery.
- It can be twisted, folded , rolled or it can be cut into your needed shapes without any loss in its efficiency an in its output.
- It is light weight due to the nanotubes and it is used in the portable electronic devices and in automobile toys, such as remote appliances also.
- It also used for medical devices like pacemakers, because it is non toxic and biodegradable well suited for medical appliances.
- Used as both battery and capacitor.
- It is flexible.
- It is ultra thin energy storage device.
- Long lasting.
- Non toxic.
- Steady power production.
- Shaped for different applications.
- High efficiency.
- Available in different sizes.
- Energy efficient.
- It is light weight.
- It is more economical.
- Can be easily disposed.
- Can be recharged.
- Generates close to 1.5 Volts of energy.
- Prone to tearing.
- Nanotubes made from carbon are expensive due to use of procedures like electrolysis and laser ablation.
- Should not be inhaled, as they can damage lungs.
- Can be used to power smart tags.
- Can be used to power single use medical devices.
- Can be used to make items like gaming cards interactive at very low cost.
