Water is the future of making better Batteries.

The future of the batteries is here.Since from the early ages batteries are a very  important part of our day to day life.A day would not last in our lives without the application of batteries.If you are still wandering that how without batteries you can't spend your day then let me give you some hint.Think!can you in this era sustain without using your Smartphones or Laptops?or can you reach a far away destination without your cars?-for watching television we need a remote control to change the channels.So,all these things are done or executed with the help of a battery right?

Currently the most commonly used batteries are Lithium ion batteries which are rechargeable and are generally used in your cell phones and Laptops and your tablet computers.Lithium ion batteries are also used in electric and hybrid vehicles but due its high cost lithium ion batteries usage in a mass public is hindered.So,scientists are coming up with an idea that would help to manufacture the battery both with less expensive and more environmental friendly.This idea is nothing but water.

Batteries generally generate electricity when the electricity passes through electrodes of the batteries that is positive cathode and negative anode.Generally the cost of the cathode is more than 70% of the other materials which is used to make lithium ion batteries.The other most important things which helps the battery is nothing but the solvent(N-Methylpyrrolidone or in short NMP) which is toxic material and generally releases flammable gases.Making batteries with this solvent also requires expensive explosion-proof processing equipments and costly solvent recovery solutions.Plus this solvent is not at all environmental friendly.

So,what the scientist are thinking is nothing but to replace this NMP solvent with water.But its not so easy as i am saying to you right now.Actually the NMP solvent makes the electrodes a good current collector substance which means makes its good enough to gather electrical charges from the cathode.But if water is being used then its slurries may not be able to smooth the electrode so that it can coat the current collector.So it requires extensive knowledge from the field of both science and engineering to perform this experiment.

The scientist so far has tried different tricks out of which the most prominent is to treat the current collector with electrified plasma which can alter the surface of the elctrode so that it can make water based slurries coat better.Using this method the price of lithium ion batteries can reduced almost one-eight of its actual price right now.Plus we can get a much more greener and environment benign battery device which will give much more better performances.The process is still in the lab and not been delivered in the market yet.Soon,it will be.

So the main thing in this whole process was nothing but Replacing NMP with Water.
