Group 4 Paper Battery
Transcript of Group 4 Paper Battery
-covalent bonds formed between carbon molecules
-held together by Van der Waals forces (London forces); electrostatic force is formed by the attraction of protons in one atom towards the electrons in the other Paper batteries:
are more durable
more flexible; higher surface-to-volume ratio
more efficient conductors
higher energy storage
natural occurring electrolyte; non- toxic between paper batteries and conventional batteries from the experts Advantages & Disadvantages of a Paper Battery functions between -75 and 150°C durable, high energy storage lightweight and flexible like paper 2.5 volts produced from battery the size of a postage stamp ink doesn’t peel off of paper battery like with other plastic films
less surface area = less power
potential poisoning over time or health problems
advance technology; only for those who can afford, leaving behind the poor unknown knowledge; to fully understand it’s potential and it’s structure
ethical problems (lethal weaponry) more expensive than normal battery
can use various liquids as an electrolytes
dry paper battery can be placed into the body
uses natural occurring electrolytes in blood, sweat, or urine to work. Why aren't Paper batteries used today? Carbon nanotechnology is expensive, though creating a carbon nanotube can quickly be accomplished it is quite costly to produce.
More research needs to be done into how these batteries can be used. i.e. health risks But in a few years, instead of reaching for your charger when your battery dies, you reach for a piece of paper... A Paper Battery Group 4 Production By: Gayathri Kalathil-Prem Karen Lai Karen James Nerissa Nankissoor Thank YOU when the paper comes into contact with an ionic liquid solution. no water in ionic liquid to freeze/evaporate in extreme environmentals Future Applications * Inexpensive reprographic (the art of recopying, reproducing or reprinting material) device * Smaller, lighter, more portable electronics * Hybrid automobiles - paper batteries would replace conventional batteries Medical devices: Pacemakers Pacemakers which use blood as a source of power is being considered because paper batteries are non-toxic and biodegradable.
