Love your gadgets but can’t seem to cope-up with their battery charging cycles and the need to give them up when the battery is no longer functional? Gadgets like smartphones, tablets, laptops or the trending wearable devices. Lithium-ion batteries could have a major overhaul in the next couple of years as scientists at Nanyang Technology University (NTU) have developed a prototype of battery that has a lifespan of over 20 years and can be charged in under 5 minutes to full charge. Now, that is some leap from the current breed of lithium-ion batteries that have half the lifecycle and take a long time to charge.

So, how is this made possible? Well, NTA associate professor Chen Xiaodong and his team replaced the graphite used in traditional lithium-ion batteries with gel made from titanium dioxide nanotubes that are around a thousand times thinner than human hair. Using titanium dioxide facilitates faster flow of ions thereby speeding up the charging process considerably.

On top of this the batteries are light-weight and can be made at a very economical cost. Chen said that an unnamed company has already licensed the technology and we could see the commercial version of these batteries in the next couple of years.

This is great news for mobile device manufacturer’s and electronics market that is constantly looking for a faster and long-lasting power source for their juice hungry gadgets. Also it could mean a push in the wearable market where the need for light-weight and thin batteries is very crucial in developing winning products.
Not only that, it could mean a revolution for electric vehicles that need a fast powered battery that lasts long without needing a recharge.

NTA associate professor Chen Xiaodong exclaimed:

Electric cars will be able to increase their range dramatically, with just five minutes of charging, which is on par with the time needed to pump petrol for current cars. Equally important, we can now drastically cut down the toxic waste generated by disposed batteries, since our batteries last ten times longer than the current generation of lithium-ion batteries.
