The document describes a paper battery, which is an ultra-thin, flexible energy storage device formed by combining carbon nanotubes with cellulose-based paper. It acts as both a high-energy battery and supercapacitor. The construction of a paper battery involves applying carbon ink to paper, laminating a lithium film, and connecting the film electrodes to electrolytes. When dipped in an ion-based liquid, a chemical reaction occurs between the electrodes and liquid to generate electricity as electrons move from cathode to anode. Paper batteries have advantages of being long-lasting, non-toxic, flexible, light weight, and able to be recharged. Potential applications include low-power devices like calculators and watches.

4.  A paper battery is an ultra-thin, flexible energy
storage device that is b used as a battery and also as a
good capacitor.
 It is formed by combining carbon Nano-tube with a
sheet of cellulose-based paper.
 A paper battery acts as both a high-energy battery
and super-capacitor.

5.  Ultra-thin size & flexible structure.
 Allows for easier transfer of electrons between the two metals.
 Operating temperature (-75 to 100 degree Celsius)
 Used to develop thin and flexible super capacitors that are light
weight and less expensive

6. Construction of a paper battery mainly includes these steps:
 Step 1: Black carbon ink is applied on a cellulose-based paper.
 Step2: Black carbon ink is being spread on a paper.
 Step3: A thin lithium film is laminated over the exposed cellulose surface.
 Step4: The cellulose paper is heated at 800C for 5 minutes.
 Step5: Next, the film is peeled off from the substrate

7.  Step6: The film acts as electrodes of the paper battery. One film is connected to
the electrolyte LTO and another film is pasted to the electrolyte LCO.
 Step7: Next, Connect a LED on both the ends of the battery and check its
functionality.

9. 1) A conventional battery contains a number of separate components that produce
electrons through a chemical reaction between the metal and the electrolyte of the
battery.
2) The Paper battery works when the paper is dipped in the ion-based liquid solution;
next a chemical reaction occurs between the electrodes and liquid.
3) The electrons move from the cathode to anode to generate electricity.
4) The best method to increase the output of the battery is to stack different paper
batteries one over the other.

11. • Used as both battery and
capacitor.
•Long lasting.
• Non toxic.
•Available in different sizes.
•Can be recharged.
•It generates close to 1.5V of
energy.
•It is durable, easily recyclable
and reusable.
•Flexible and Very Light Weight

12.  Carbon Nano-tubes are very expensive.
 Batteries with large enough power are unlikely to
be cost effective.
 Should not be inhaled, as they can damage lungs.
 Theses batteries generate e-wastage.

13.  Low battery power devices like in
• calculators,
• wrist watch, and
• other low drain devices ( like
clocks and remote controls)
 Laptop batteries,
 Mobile phones,
 Hand held digital cameras
 Wireless communication devices like
• mouse,
• keyboard,
• Bluetooth
• headphones, etc
