New ultra-fast charging batteries

New ultra-fast charging batteries that last 20 years, developed by NTU that can be recharged up to 70 per cent in only two minutes.

The new generation batteries developed by scientists at Nanyang Technology University (NTU), also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.

This will have a wide-ranging impact, especially for electric vehicles, where consumers are put off by the long recharge times and its limited battery life.

The technology is currently being licensed by a company for eventual production. Prof Chen expects that the new generation of fast-charging batteries will hit the market in the next two years. It also has the potential to be a key solution in overcoming longstanding power issues related to electro-mobility.

Prof Chen, said:

“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.”

The 10,000-cycle life of the new battery also mean that drivers of electric vehicles would save on the cost of battery replacements, which could cost over US$5,000 each.
