"A new battery technology from Japanese automaker Nissan may soon speed up the charging time for electric vehicles from eight hours to as little as 10 minutes.
Researchers at Japan’s Kansai University and Nissan modified a capacitor to let it hold more power, according to an article on Paul Tan's Automotive News.
But the article said the researchers do not appear satisfied, planning to bring down the charge time further to three minutes or less.
The article noted that present lithium-ion batteries can take up to eight hours to recharge fully.
In the project, the researchers used a composite from tungsten oxide and vanadium oxide instead of the usual carbon for the capacitor’s electrode.
The article added the modified capacitor also held nearly the same storage capacity and voltage as lithium-ion batteries.
However, it added it may take about 10 years before the technology can be commercialized.
Still, this may help cut production costs for electric cars and make them more popular for drivers in a hurry.
Meanwhile, Nissan also unveiled what may be the world’s first ultra high tensile strength steel to be rated at 1.2 gigapascals (GPa)." [Continue reading...]
