paper battery
- 1. Presented By- Shivangi Shringi M.Tech 2nd Year VLSI Design 15219004
- 2. A battery convert chemical energy into the electrical energy. Batteries have become a common power source for many household and many industrial application.
- 4. . Based on the rechargeable nature :- 1.Non rechargeable or primary cells 2.Rechargeable or secondary cells Based on the size :- 1.Miniature batteries 2.Industrial batteries Based on nature of electrolyte:- 1.Dry cell 2.Wet cell
- 5. This can produce current immediately on assembly. Disposable voltaic batteries. One time usable. Can not be recharged. These are most commonly used in portable devices.
- 7. These batteries must be charged before use Secondary cells can be recharged by applying electric current Which reverses the chemical reactions that occur during its use.
- 9. Explosion
- 10. Corrosion
- 11. Environmental pollution Electronic waste
- 14. Has the ability to wick fluids via capillary action Can be used both as reservoir for electrolytes and binding element Cheap and Abundantly Available Thin, Light Weight And Flexible Biocompatible and Biodegradable Combustible and Non- toxic
- 16. Electrochemical Batteries Bio fuel Cells Super Lithium- ion Batteries
- 18. Sensors for- 1. Blood 2. Urine
- 19. 1. Microbial fuel cells (MFCs)
- 20. 2. Enzymatic biofuel cells (EBFCs)
- 21. A paper battery is basically a device which can act both as a capacitor and as a battery It is a flexible, light weight device It is basically formed by combination of cellulose with carbon nano-tubes (CNTs). It consists of infusion of CNT with paper consisting of an ionic liquid as an electrolyte.
- 25. "The new battery can be recharged in half the time and the fire risk is much smaller“ - Nick Hayek, Vice Representative Director of Belenos.
- 26. •Pace makers in heart (uses blood as electrolyte) •Used as alternate to conventional batteries in gadgets
- 27. •Powered smart cards RF id tags •Smart toys, children sound books •E-cards, greetings, talking posters
Editor's Notes
- The invention of the first battery in 1800 by Alessandro Volta.
- Electrons flow from the negative terminal (anode) towards the positive terminal (cathode)
- The widespread use of batteries has created many environmental concerns, such as toxic metal pollution
- 1………..A paper battery is a flexible, ultra-thin energy storage and production device. 2………..The device are able to produce 2.5 volts of electricity from a sample the size of a postage stamp. 3………Can work in temperature range between -75 to 150 degree Celsius.
- Paper batteries may be folded, cut or otherwise shaped for different applications without any loss of integrity or efficiency.
- Motivation::::: extremely cheap and ubiquitously available;(ii)combustible, so the paper-related devices can be economically disposed off by an incinerator;(iii)thin, light weight and flexible;;; biocompatible and biodegradable;;;;; it has the ability to wick fluids via capillary action.;;;; no external pumps and tubing are required to move liquid through the patterned fluidic pathways within the paper;;;;; , ability to bind functional chemical groups;;;;;can be used both as reservoir for electrolytes and binding element
- The main objective of those patterning methods is to create hydrophobic barriers on paper that constitute the walls of capillary channel
- Low operating voltage 1.5 v, low current …………power range from micro watt to milli watt……..paper is of highly poros cellulose…… cu cathode ,Al anode Electrolyte--- water, blood, tears, urine, NaCl, Max power 1.5mW as a AA battery

- The rapid electricity generation should be noted since conventional MFCs require long start-up times (typically several days to a week), which is attributed to the accumulation and acclimation of bacteria on the anode of MFCs (Qian et al., 2009). This is probably because a hydrophilic paper reservoir rapidly absorbs the anolyte and immediately promotes the attachment of a number of bacteria cells to the anode
- The method involves coating substrate of stainless steel with carbon nanotubes. The coated substrate is the dried at 80 degree Celsius for five minutes, after which the material is peeled off. A pair of films are used for each paper battery with each film being pasted to different electrolytes like LTO and LCO. A paper is then sandwiched between the two films using adhesive. If one can recall traditional batteries work in the manner where positive charged particles called ions and negative charged particles called electrons move between positive electrodes called anode and negative electrode called cathode. Current flows as electrons flow from anode to the cathode through the conductor, since the electrolyte is an insulator and doesn’t provide a free path for electrons to travel. ####these batteries are rechargeable and durable for long period of time.#####generate high operating voltage of 2.3v.
- at least 30 percent more efficient than conventional models;;;;;;
