John Goodenough is one of the original developers of the lithium ion battery. Recently, he has been involved in developing some battery technology that has 3-10 times or greater the energy density of lithium ion batteries. And, they’re very safe, non-toxic, and can be charged REALLY fast!
“Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted. We believe our discovery solves many of the problems that are inherent in today’s batteries,” Goodenough said.
These batteries can also be made at a much lower cost since sodium can be used instead of lithium, which is in massive abundance in sea water. The electrolytes in this battery are actually made of a solid GLASS and is changing the way batteries and electricity are looked at.
