Flexible thin film battery

A team of scientists has developed a flexible thin film battery that could power the next generation of wearable electronics. The device, developed by researchers at the University of Illinois at Urbana-Champaign, consists of three layers: two electrodes sandwiching a liquid slurry containing charged particles derived from titanium dioxide dissolved in water. The top layer is a polymer mesh that allows ions to diffuse through it. It also serves as an ion collector, gathering electrons given off during charging and passing them to the bottom electrode to complete the circuit. On its own, this design wouldn't work because the slurry would stop conducting once all the ions were pulled out into the electrodes on either side. To get around this problem, Zhao and his colleagues added another electrode, known as a counter electrode, to pull extra electrons back out of the titanium dioxide.

Features:

-Flexible, can be used in wearable electronics

-Can charge a device quickly and efficiently

-Will not overheat the device because of its low power consumption

-Has a longer lifetime than lithium ion batteries

-Safe to dispose of because it's made of environmentally friendly materials

Possible Applications:

-Cell phones, laptops, music players, wearables devices etc…

-Safety features in cars, home appliances etc.

-Medical equipment for surgeries and anything else that uses batteries.

Pros

  1. Flexible
  2. Quickly charges devices
  3. Safe to dispose of because it's made of environmentally friendly materials
  4. Can be used in wearable devices which will help them stay on the right track for making new technologies like Google glass
  5. Will not overheat the device because of its low power consumption
  6. An efficient battery that won't die as fast as lithium ion batteries do, giving more time to use the device before needing to charge it again
  7. Has a longer lifetime than lithium ion batteries
  8. Cell phones, laptops, music players, wearables devices etc… can use this kind of battery now! Not just things like safety features in cars and home appliances but also medical equipment for surgeries and anything else that uses batteries (i.e defibrillators)
  9. Can be used to make portable electronic devices smaller and more portable than ever before!
  10. The materials used in this battery are environmentally friendly and will not pollute the earth; we all know that lithium ion batteries, which most wearable and portable devices use currently can run out of power quickly and start to deteriorate over time due to heat damage

Cons

1.Not as efficient as some other batteries because of its three layer design but it still works well enough for our purposes I think!

2.Some people may not like the idea of having a liquid solution as an electrode because they fear it might catch on fire or explode if punctured by something sharp.

3.Not ideal for flying devices because if it's punctured, the thin liquid slurry will leak out of any possible holes and render the battery useless

4These are just some problems that I can think of at the moment but there may be more to come!

5.Look, I know this article is pretty short but the team of scientists published it in Nature Materials and there's only so much you can discuss about a battery!

6.The scientists made an awesome design though, no doubt about that! And if we want more articles on batteries then we need to reach out to some other universities for their research too.

conclusion:

Based off of what I read in the article, this new thin film battery design is an awesome innovation! It has many benefits like being flexible and environmentally friendly. There are also some possible applications which include cell phones, laptops, music players, wearables devices etc… even medical equipment for surgeries and anything else that uses batteries (i.e defibrillators). Finally, the material used in this battery is not dangerous to people or damaging to the environment because it contains titanium dioxide particles suspended in water which will not burn up if punctured! Overall this might be a good solution for some problems with existing batteries on the market right now.
