Lithium ion battery

Forty years ago, professor John Goodenough developed the lithium ion battery and kick-started the wireless revolution. From electric cars to mobile phones, the world now relies on rechargeable batteries. Now, 97, and just awarded the Nobel Prize for Chemistry, Professor Goodenough still works at the University of Austin in Texas. Seventeen-year-old Adam from Poland asks him about lessons from life as well as lessons from science, and why he still works on developing the lithium ion battery even further.
