The flexible and thin energy storage device which can
be used as a battery is called as paper battery. This paper battery can also be
used as a capacitor produced by merging the nano-tubes(made using carbon) and
nano-composite paper (made using
cellulose)
A paper battery is designed to use a spacer
formed largely of cellulose (the major constituent of paper). It incorporates
nanoscopic scale structures to act as a high surface area electrodes to improve
conductivity
WORKING:
The conventional rechargeable batteries which we use
in our day to day life consist of various separating components which are used
for producing electrons with chemical reaction of metal and electrolyte. When
this paper battery is dipped in ion-based liquid, then electricity is generated
by the movement of electrons from cathode terminal to anode terminal.
PRO’S:
- It can be used as both supercapacitor & battery.
- Provides a steady power
- Low cost and can be easily disposed
- It has capacity to produce 1.5v energy also rechargeable
CON’S:
- Prone to tearing
- Cost expensive and less efficiency
