Charge your phone in ten seconds

You are off out for the evening. Everybody is waiting for you. Your mobile is essential; there is no way you can leave home without it. How would you meet up with everybody or order that taxi? You might miss an important text or email message and you need to check a few things on-line. This is the modern age. We can no longer afford to be distanced from our mobile phones.

You check it and the battery is nearly flat. You check your spare battery. It is flat also. Now what do you do? It will take at least 30 minutes to get sufficient charge to last the evening. You should have checked earlier.

This will soon be a scenario from the past. In the future you will plug your mobile phone into the charger and 10 seconds later it will be fully charged. How can that be?

The answer concerns that new buzzword nanotechnology. Your phone will currently be using what is called a lithium ion battery. They are great batteries to use because they are very light and will hold a lot of charge. The problem is that they can only be charged quite slowly. The reason for this is that all those lithium ions that have been made while releasing electrons to power your phone have to be converted back to their original state and this takes quite a time.

Now a new type of lithium ion battery has been invented that uses nanotechnology. The battery cathode (that’s the negative end) is made of nano-sized balls of a chemical called lithium iron phosphate coated in another chemical called lithium phosphate. These balls are only 50 nanometres in diameter, which is just about the size of a virus. It turns out that these nanospheres are super efficient at absorbing the lithium ions during the battery recharging cycle. The inventors who work at the Massachusetts Institute of Technology believe that if they made a phone battery out of this it would charge in ten seconds.

They still have a few little problems to iron out but it is probably not that far away.
