Some people have the wrong name. The inventor of the lithium-ion battery, that likely powers the device you’re reading this on right now, is 94 years old—but not satisfied with his invention as his last name would suggest. John Goodenough of the University of Texas at Austin has invented a better battery that lasts longer, charges faster, doesn’t use any lithium, and won’t explode (that can happen to lithium batteries). The new battery has three times the energy density of the lithium-ion one, which means that for the same weight of batteries, a car would have three times the range. And it cannot explode.
