There is a huge demand for batteries that can charge fast but most batteries and methods that allow this to happen also shorten the battery’s lifespan. What if the battery could charge to 70% in 2 minutes. What if that same battery could last for up to 20 years. Thats right, someone’s actually made them.
Researchers at Nanyang Technology University have developed lithium ion batteries that can allegedly live up to these promises. They have been able to speed-up the chemical reactions that occur inside the battery. This makes the battery capable of charging at rapid speeds. It is accomplished by replacing the traditionally used graphite anode with a titanium dioxide nanotubes anode.
This battery is also capable of providing 10,000 charging cycles compared to the usual 500 charging cycles of current generation mass-produced batteries.
Contrary to what you might expect, these tiny titanium tubes are cheap and relatively easy to make as well. The material can be found in soil and is also used as a food additive so its a safe material.
The art to this is in making thin nanotubes that are a thousand times thinner than the diameter of a human hair. These tubes are what makes the chemical reactions occur faster.
These batteries are expected to start mass production in the year 2016. The future of smartphones rests on the production of better batteries. Having battery technology like this could also revolutionize the electric car industry in a few years if it is successful.
