Could This Be the Battery That Revolutionizes Our Cars and Phones? | NBC News

The co-inventor of the lithium-ion battery, which powers almost every modern mobile device and many newer electric cars, says he’s developed a safer battery that lasts three times longer.

In a filing with the U.S. Patent and Trademark Office and in research published in the March edition of the journal Energy & Environmental Science, John Goodenough and colleagues at the University of Texas report that their new battery technology could produce a safe, non-explosive cell able to power an electric car much longer than current batteries do — with charging times measured in minutes, not hours.
