Nobel Prize-winning battery pioneer John Goodenough dies at 100.

John Goodenough, the materials scientist who led the development of lithium-ion batteries, has died at the age of 100. His work revolutionized handheld electronics and electric vehicles. Goodenough was awarded a share of the 2019 Nobel Prize for Chemistry for his contributions to the development of lithium-ion batteries. He discovered that a cathode made of cobalt oxide could achieve a high density of stored energy with an anode other than metallic lithium. Goodenough received many other awards including the Japan Prize in 2001, the Enrico Fermi Award (2009) and the US National Medal of Science (2011).
