Nanyang Technology University (NTU) researchers develop batteries with not only ultra-fast charging times but also a lifespan of over 20 years, over 10 times that of existing lithium-ion batteries.
According to the researchers the batteries recharge up to 70% in only 2 minutes, making them particularly useful for electric vehicles as well as any other piece of battery-powered CE.
Current rechargeable lithium-ion batteries last around 500 recharge cycles, the equivalent of 2-3 years of typical use, with each cycle taking around 2 hours to fully charge the battery.
The secret sauce behind the NTU-developed battery is titanium dioxide gel replacing the graphite anode (negative pole) of lithium-ion batteries. Titanium dioxide is naturally found in soil in spherical shape, and the NTU team managed to turn it into tiny nanotubes in order to speed up the chemical reactions in the new battery.
