Scientists at Nanyang Technology University (NTU) have developed ultra-fast charging batteries that can be recharged up to 70 percent in only two minutes.
The new-generation batteries also have a long lifespan of over 20 years, more than 10 times compared to existing lithium-ion batteries.
In the new NTU-developed battery, the traditional graphite used for the anode (negative pole) in lithium-ion batteries is replaced with a new gel material made from titanium dioxide. Titanium dioxide is an abundant, cheap and safe material found in soil.
Naturally found in spherical shape, the NTU team has found a way to transform the titanium dioxide into tiny nanotubes, which is a thousand times thinner than the diameter of a human hair. The development speeds up the chemical reactions taking place in the new battery, allowing for superfast charging.
The breakthrough has a wide-ranging impact on all industries, especially for electric vehicles, where consumers are put off by the long recharge times and its limited battery life.
