2.  A battery converts chemical energy into
electrical energy.
 The ordinary lithium batteries have the dis-
advantages like self-diffusion ,ageing.
 Now a days the use of batteries became more
familier and the cost of them are go on
incresing day by day .
 A paper battery is a perfect alternative and
effective repalcement of ordinary batteries.

3.  A paper battery is a battery engineered to use
a paper –thin sheet of cellulose infused with
aligned carbon nano tubes.
 Paper battery is flexible and ultra thin energy
storage device.
 It acts as both high energy -battery and
super-capacitor.
 it can be folded ,cut or otherwise shaped for
different applications with out loss of
efficiency.

6.  The main concept behind paper battery is
CNT’s {carbon nano tubes}
 They are allotropes of carbon with a
cylindrical nanostucture.
 CNT’s exibit extraordinary strength and
unique electrical properties
 Nano tubes are fullerene structural family.
 CNT’S are also known as “buckytubes”.

8.  While a conventional battery contains a number of separate
components, the paper battery integrates all of the battery
components in a single structure ,making it more efficient.
 Traditional batteries produce electrons through a chemical
reaction between electrolyte and metal .
 Paper battery produces electrons due to interaction of
electrolytes LTO&LCO.
 Electrons collect on the negative terminal of the batter y and
flow along a connected wire to the positive terminal during
discharging.
 Electrons must flow the negative to the positive terminal for
the chemical reaction to continue

9.  The flexible battery can function even if it is
rolled up ,or folded.
 We can get 2.5volts of electricity from a
simple size of postage stamp.
 If we stack 500 sheets together in ream,
that’s 500 times the voltage .
 If we rip the paper in half we can reduce the
power by50%.
 It is eco friendly.

10.  These batteries are used in cosmetics.
 In RFID tag applications.
 In microprocessors.
 In medical stream.
 In functional cards.
 In thin displays.

11.  The range of possible applications for paper
batteries derives from their important
advantages compared to conventional
batteries.
 They can be made in virtually any shape and
size to meet the requirements of each
application.
 These batteries are rechargeable .
 Less weight and low cost and compact in
nature.
