Born in Jena, Germany, to American parents, Goodenough spent a career spanning more than seven decades making foundational contributions to the understanding of magnetic materials, computer memory technology, and electrochemical energy storage. His identification of lithium cobalt oxide as a cathode material for rechargeable lithium-ion batteries, achieved while he was at the University of Oxford in the early 1980s, enabled the portable electronics revolution and remains central to devices ranging from smartphones to electric vehicles. In 2019, at the age of 97, he was awarded the Nobel Prize in Chemistry alongside M. Stanley Whittingham and Akira Yoshino, making him the oldest Nobel laureate in history. He continued active research at the University of Texas at Austin until the final years of his life, passing away on June 25, 2023, one month before his 101st birthday.

Early Life

John Bannister Goodenough was born on July 25, 1922, in Jena, in the German state of Thuringia, which was then part of the Weimar Republic. His father, Erwin Ramsdell Goodenough, was an American scholar of religion who was studying in Germany at the time. His mother was Helen Miriam Lewis. The family returned to the United States, where Goodenough grew up.

Goodenough's childhood was shaped by the intellectual environment of his family, though his early years were not without difficulty. He struggled with dyslexia as a young student, a challenge that he later spoke about openly. Despite this, he demonstrated strong aptitude in mathematics and science. He attended the Groton School, a prestigious boarding school in Massachusetts, where he excelled academically and developed the intellectual foundations that would support his later scientific career.

During World War II, Goodenough served in the United States Army as a meteorologist, an experience that interrupted his academic trajectory but also broadened his scientific perspective. His military service took place during a period of immense global upheaval, and the experience shaped his later commitment to scientific work that could benefit society. After the war, he returned to academic life, determined to pursue advanced study in physics and materials science.

Education

Goodenough earned his bachelor's degree in mathematics from Yale University in 1943, shortly before entering military service. After the conclusion of World War II, he pursued graduate studies at the University of Chicago, where he worked under the supervision of Clarence Zener, a prominent physicist known for his work on the electronic properties of solids. Goodenough completed his doctoral dissertation, titled "A Theory of the Deviation from Close Packing in Hexagonal Metal Crystals," and received his Ph.D. in physics from the University of Chicago in 1952. His graduate training at Chicago provided him with a deep understanding of solid-state physics and crystallography that would underpin his subsequent research on magnetic materials, electronic structures, and electrochemistry.

Career

Lincoln Laboratory (1952–1976)

Following the completion of his doctorate, Goodenough joined MIT's Lincoln Laboratory in Lexington, Massachusetts, where he would spend more than two decades as a research scientist. Lincoln Laboratory, a federally funded research and development center, was at the forefront of defense-related technology during the Cold War era, and it provided Goodenough with an environment in which fundamental research could have practical applications.

During his time at Lincoln Laboratory, Goodenough made significant contributions to the understanding of magnetic materials and solid-state physics. He was instrumental in developing the theoretical framework known as the Goodenough–Kanamori rules, which describe the sign of the magnetic superexchange interaction in transition metal oxides and other materials. These rules, formulated in collaboration with Junjiro Kanamori, became fundamental to the study of magnetism in condensed matter physics and remain widely used in the field.

Goodenough also contributed to the development of materials for computer random-access magnetic memory (RAM), work that helped advance the computing technology of the era. His research during this period established him as a leading figure in solid-state physics and materials science, with a reputation for combining theoretical insight with practical materials development.

University of Oxford (1976–1986)

In 1976, Goodenough left Lincoln Laboratory to become a professor and head of the Inorganic Chemistry Laboratory at the University of Oxford in England. This move marked a pivotal transition in his career, as it was at Oxford that he would make the discovery for which he is most recognized: the identification of lithium cobalt oxide (LiCoO₂) as a cathode material for rechargeable lithium-ion batteries.

The development of the lithium-ion battery was a collaborative achievement involving researchers across multiple institutions and countries. In the 1970s, M. Stanley Whittingham, working at Exxon, had demonstrated that lithium ions could be intercalated into titanium disulfide to create a rechargeable battery. However, this design used metallic lithium as an anode, which posed safety risks including the formation of dendrites that could cause short circuits and fires.

Goodenough's contribution was to identify a new class of cathode materials—layered oxide compounds—that could store and release lithium ions at a higher voltage than Whittingham's titanium disulfide cathode. In 1980, Goodenough and his research team at Oxford demonstrated that lithium cobalt oxide could serve as a cathode, effectively doubling the voltage of existing lithium batteries and creating the foundation for a practical, rechargeable lithium-ion cell. This was a breakthrough achievement. The higher voltage meant greater energy density, which was essential for making batteries small and powerful enough for portable electronic devices.

Goodenough's cathode material was subsequently paired with a carbon-based anode by Akira Yoshino at Asahi Kasei Corporation in Japan in 1985, eliminating the need for reactive metallic lithium and creating the first commercially viable lithium-ion battery. This battery design was commercialized by Sony in 1991 and rapidly became the dominant rechargeable battery technology worldwide.

The impact of this work was profound. Lithium-ion batteries enabled the development of laptop computers, mobile phones, tablets, and eventually electric vehicles and grid-scale energy storage systems. Goodenough himself noted in interviews the broad societal implications of the technology, including its potential role in reducing dependence on fossil fuels.

University of Texas at Austin (1986–2023)

In 1986, Goodenough joined the University of Texas at Austin as a professor in the departments of Materials Science, Electrical Engineering, and Mechanical Engineering, holding the Virginia H. Cockrell Centennial Chair in Engineering. He would remain at the university for the rest of his career, continuing active research for nearly four decades.

At UT Austin, Goodenough continued to advance battery technology and materials science. He and his collaborators developed the lithium iron phosphate (LiFePO₄) cathode material in the late 1990s, which offered advantages over lithium cobalt oxide in terms of safety, cost, and environmental impact. Lithium iron phosphate batteries became particularly important for applications requiring large-format cells, including electric vehicles and stationary energy storage systems.

Goodenough's research interests at UT Austin also encompassed the broader physics of transition metal oxides, including their electronic, magnetic, and structural properties. He investigated materials for solid oxide fuel cells and explored the fundamental relationships between crystal structure and electronic behavior in complex oxides. His work contributed to the theoretical understanding of metal-insulator transitions, orbital ordering, and cooperative phenomena in strongly correlated electron systems.

Even in his nineties, Goodenough continued to pursue new research directions with notable vigor. In 2017, at the age of 94, he and his collaborator Maria Helena Braga announced the development of a new type of solid-state battery using a glass electrolyte, which they suggested could offer higher energy density, faster charging, and improved safety compared to conventional lithium-ion batteries. This work attracted significant attention, though it also generated scientific debate about the mechanisms involved. A 2015 profile in Quartz described Goodenough as a researcher who, at 92, was still actively pursuing the next generation of battery technology, driven by a desire to develop energy storage solutions that could help address climate change.

Goodenough mentored numerous graduate students and postdoctoral researchers during his time at UT Austin, many of whom went on to become prominent researchers in their own right. Among his notable students and postdoctoral associates was Arumugam Manthiram, who became a leading materials scientist in the field of energy storage.

Personal Life

Goodenough was known for his intellectual curiosity, warm personality, and enduring commitment to scientific research. He married Irene Wiseman in 1951, and she remained his partner throughout his career until her death. Goodenough spoke in interviews about the influence of his personal experiences, including his childhood struggles with dyslexia and his wartime service, on his scientific outlook and perseverance.

He remained active as a researcher at the University of Texas at Austin well into his nineties, maintaining a regular presence in his laboratory and continuing to publish scientific papers. Colleagues described him as an engaged and generous mentor who was deeply interested in the work of younger scientists.

Goodenough died on June 25, 2023, in Austin, Texas, at the age of 100, one month before what would have been his 101st birthday. At the time of his death, he was the oldest living Nobel Prize laureate, a distinction he had held since August 27, 2021.
