Physics World reports the passing of John Goodenough, a pioneering battery inventor and Nobel Prize winner, at the age of 100.

Date:

John Goodenough, a renowned physicist and inventor, passed away on November 25, 2021, at the age of 100. Goodenough was best known for his groundbreaking work in the field of battery technology, which earned him numerous accolades, including the Nobel Prize in Chemistry in 2019.

Born in Jena, Germany, in 1922, Goodenough grew up in the United States and earned his Ph.D. in physics from the University of Chicago in 1952. He went on to work at various institutions, including MIT, the University of Oxford, and the University of Texas at Austin, where he spent the majority of his career.

Goodenough’s most significant contribution to science was his development of the lithium-ion battery, which has revolutionized the way we use portable electronic devices. The lithium-ion battery is now used in everything from smartphones and laptops to electric cars and renewable energy storage systems.

Goodenough’s breakthrough came in the early 1980s when he discovered that lithium cobalt oxide could be used as a cathode material in rechargeable batteries. This discovery led to the development of the first commercially viable lithium-ion battery, which was introduced by Sony in 1991.

Goodenough continued to work on improving battery technology throughout his career, and his research led to the development of new materials and designs that have made batteries more efficient, longer-lasting, and safer.

In addition to his work on batteries, Goodenough also made significant contributions to the field of solid-state physics. He was a pioneer in the study of magnetism and ferroelectricity in materials, and his research has had applications in fields such as data storage and telecommunications.

Goodenough’s contributions to science were recognized with numerous awards and honors throughout his career. In addition to the Nobel Prize, he received the National Medal of Science in 2013 and was inducted into the National Inventors Hall of Fame in 2020.

Goodenough’s legacy will continue to inspire future generations of scientists and inventors. His work has had a profound impact on our daily lives, and his contributions to the field of battery technology have helped pave the way for a more sustainable and energy-efficient future.
