Three researchers won the Nobel Chemistry Prize on Wednesday for the development of lithium-ion batteries, paving the way for smart-phones and a fossil fuel-free society. John Goodenough of the United States - at 97 the oldest person to be awarded a Nobel prize - Britain's Stanley Whittingham, and Japan's Akira Yoshino will share the nine million Swedish kronor (about US$914,000 or €833,000) prize equally, the Royal Swedish Academy of Sciences said.
