You probably have evidence of a Nobel Prize in your pocket. This year’s Nobel Prize in Chemistry goes to the pioneers of the lithium-ion battery, an invention that has become ubiquitous in the wireless electronics that power modern life: your phone, your laptop and sometimes even your car. Lighter and more compact than the lead and nickel-cadmium batteries of yesteryear, lithium-ion batteries, with further tinkering, could provide a path to storing energy to power homes, airplanes—and even the grid. 

The $900,000 prize is split between three scientists: Stanley Whittingham, of Binghamton University in New York, John Goodenough, of the University of Texas in Austin, and Akira Yoshino of Asahi Kasei Corporation in Tokyo. Goodenough, 97, is the oldest-ever recipient of a Nobel Prize.
