• A paper battery is a flexible, ultra
thin storage and production
device formed by combining
carbon nano tube with a
conventional sheet of cellulose
based paper.
• It acts as both a high energy
battery and super capacitor,
combining two components that
are separate in traditional
electronics.
5
GENERAL LI-ION BATTERY
•Generally li-ion rechargeable batteries are used
in mobiles, laptops and most of the electronic
devices.
•3 primary functional component of li-on battery
are:
1. -vet electrode (graphite)
2. + vet electrode(cobalt oxide)
3. Electrolyte (lithium salt in organic solvent)
• During discharge and charging, lithium ions
li+ carry the current from the negative to the
positive electrode and vice versa, through
the non-aqueous electrolyte
6
DISADVANTAGES OF Li-ION
•EXPENSIVE
•DELICATE
•REGULATIONS
7
WHY TO USE PAPER BATTERY
•Ultra thin size and flexible structure
•Exhibits property of super capacitor (22F -36F per gram).
•Operating temperature (-75 to 100 degree Celsius).
•Provides both long term, steady power and burst of energy.
•Cost effective.
8
CARBON NANOTUBES
•Carbon nano tubes are allotropes of carbon with a
cylindrical nano structure
•Nano tubes are members of the fullerene structural family,
the diameter of a nano tube is on the order of a few
nanometres
•The structure of a nano tube strongly affects its electrical
properties.
•For a given (name) nano tube, if n=m, the nano tube is
metallic; if n-m is a multiple of 3, then the nano tube is
semiconducting with a very small band gap, other wise the
nano tube is a moderate semi conductor.
9
10
CONSTRUCTION OF PAPER BATTERY
•CNT thin films were coated onto stainless
steel(ss) substrates with a solution based
process
•The concentration of CNT is 1.7 mg/ml.
•A dried 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 film act as electrodes of paper battery.
Paper is sandwiched between two electrolytes
LTO and LCO with PVDF (poly vinylidene
fluoride) acting as glue.
11
12
STRUCTURE OF PAPER BATTERY
13
WORKING
•While conventional battery contains a number of separate
components, the paper battery integrates all of the battery
components, in a single structure, making it more energy efficient.
•Traditional batteries produce electrons through a chemical reaction
between electrolyte and metal
•Paper battery produce electrons due to the interaction of electrolytes
LTO & LCO.
•Electrons collect on the negative terminal of the battery and flow along
a connected wire t o the positive terminal during discharging.
•Electrons must flow from the negative to the positive terminal for the
chemical reaction to continue
14
ADVANTAGES
•Biodegradable and non toxic
•Reusable
•Durable
•Rechargeable
•Non leakage and overheating
•Light weight and flexible
15
APPLICATIONS
•Power stations
•Medical science
•Electronics
•Automobiles and aircrafts
•Hybrid car batteries
•Long air flights reducing refuelling
•Light weight guided missiles
16
PAPER BATTERY OFFERS FUTURE POWER
•The black piece of paper can power a small light
•Flexible paper batteries could meet the energy demand of the next generation
of gadgets.
•The ambition is to procure reams of paper that could one day power a car.
•The paper battery was a glimpse into the future of power storage.
Thank you
