Dr. John Goodenough, the renowned scientist credited with inventing the lithium-ion battery, has passed away at the age of 100, as confirmed by the University of Texas at Austin. Although not a household name, Goodenough’s contributions to technology have had a profound impact on our daily lives, making cellphones, laptops, and electric vehicles practical and widely accessible.
While researchers had been exploring lithium batteries before, it was Goodenough who achieved a major breakthrough in 1980 while at the University of Oxford. He developed a cathode with layers of lithium and cobalt oxide, which significantly increased the voltage and safety of the battery. Compared to previous battery technologies, such as lead-acid and nickel-cadmium, Goodenough’s lithium-ion battery had a much higher capacity.
However, the technology did not truly flourish until Dr. Akira Yoshino, a scientist at Asahi Kasei Corporation, replaced raw lithium with safer lithium ions, leading to the creation of the first consumer-friendly rechargeable lithium-ion battery by Sony in 1991. This breakthrough in battery performance paved the way for sleeker, faster, and longer-lasting cellphones, laptops, and most importantly, enabled the viability of electric cars.
Goodenough’s contributions to technology extended beyond the lithium-ion battery. During his time at MIT in the 1950s and 1960s, he played a significant role in pioneering the technology that eventually became random access memory (RAM), a crucial component in many computing products. He was also known for collaborating and sharing patents with colleagues, reflecting his commitment to advancing technology through collaboration.

Even though Goodenough may not have been a household name, his work did receive recognition from the scientific community. He was awarded the Nobel Prize in Chemistry in 2019 and the US National Medal of Science in 2011, among other prestigious accolades. His dedication to research continued well into his nineties, as he worked on developing next-generation battery technologies that promised breakthrough performance for renewable energy and electric vehicles.
While industries are gradually moving on from lithium-ion batteries, exploring alternatives such as solid-state batteries with higher energy densities, faster charging capabilities, and lower costs, there is no denying the lasting impact of Goodenough’s contributions. The modern tech landscape owes a great deal to his efforts, and his legacy will continue to shape advancements in technology for years to come.
As we bid farewell to this influential scientist, it is important to recognize the transformative power of his work. Goodenough’s revolutionary ideas and relentless pursuit of innovation have shaped the way we interact with technology on a daily basis. The cellphones we rely on for communication, the laptops that facilitate our work and entertainment, and the electric vehicles that are gradually replacing traditional cars all owe a debt of gratitude to Dr. John Goodenough. His vision and dedication have left an indelible mark on the world of technology.
