John B. Goodenough was a famous scientist. 
Goodenough is best known for his work on batteries. 
He won many big awards for his work. In 2019, he won the Nobel Prize in Chemistry. This is a very special prize. He was 97 years old when he won it. This made him the oldest person to ever win. He lived to be 100 years old. His discoveries still help our world today.
John B. Goodenough was a famous scientist who changed how we use energy. 
Goodenough discovered new ways to make batteries better. He focused on a part called the cathode. The cathode is one of the two main parts in a battery. In 1980, while working in Oxford, he found a special material. This material was called lithium cobalt oxide. It was very lightweight and held a lot of energy. This discovery helped double the capacity of lithium-ion batteries. Because of this, batteries could become much smaller and stronger. 
His journey to becoming a great scientist was not always easy. He was born in Jena, Germany, in 1922. As a young student, he had dyslexia. This is a condition that makes reading and writing difficult. At that time, many people did not understand it well. He had to teach himself how to write. He worked very hard to succeed in school. He eventually graduated from Yale University and later earned a Ph.D. from the University of Chicago in 1952.
Throughout his life, Goodenough earned many important honors. He worked at MIT and the University of Oxford. Later, he became a professor at the University of Texas at Austin. He won many prizes like the National Medal of Science and the Draper Prize. In 2019, he won the Nobel Prize in Chemistry. He shared this prize with M. Stanley Whittingham and Akira Yoshino. At 97 years old, he became the oldest person ever to win a Nobel Prize. 
Today, we see the results of his work everywhere we look. When you use a cordless power tool, you are using his ideas. When people drive electric cars, they rely on battery technology he helped build. He even worked on new ideas like glass batteries. He wanted to find ways to use less fossil fuel. His goal was to help the Earth by finding better energy. He continued to study and work even when he was 98 years old.
John Bannister Goodenough was a pioneering American materials scientist and solid-state physicist. 
Goodenough's most significant breakthrough involved the chemistry of battery cathodes. A cathode is the positive electrode in a battery cell. In 1980, while working at the University of Oxford, he identified a specific material. This material was lithium cobalt oxide, written as LiCoO2. He discovered that this substance was lightweight and had a high energy density. By using this material, he was able to double the capacity of lithium-ion batteries. This discovery allowed batteries to hold more power while remaining small. This process is essential for making devices like smartphones and laptops practical.
His scientific career involved many different types of advanced research. At the MIT Lincoln Laboratory, he led teams developing random-access magnetic memory. He studied the metal–insulator transition behavior in transition-metal oxides. This research helped him develop the Goodenough–Kanamori rules. These rules help scientists predict the sign of magnetic superexchange in materials. Superexchange is a key property for high-temperature superconductivity. Later, at the University of Texas at Austin, he explored different electrode materials. He and Arumugam Manthiram discovered the polyanion class of cathodes. These materials, such as lithium-iron phosphates, produce higher voltages. They are now commonly used in smaller devices like power tools.
Goodenough's path to scientific greatness was marked by personal perseverance. He was born in Jena, Germany, on July 25, 1922. During his school years, he struggled with dyslexia. This is a condition that affects reading and writing. Because it was poorly understood at the time, he went undiagnosed. Some teachers even viewed him as a "backward student." However, he taught himself to write to pass entrance exams. He eventually earned a full scholarship to Groton School. He graduated at the top of his class in 1940. He later graduated summa cum laude from Yale University.
After Yale, he earned a Ph.D. in physics from the University of Chicago in 1952. He studied under the theorist Clarence Zener. During this time, he also worked with the famous physicist Enrico Fermi. Goodenough spent many years as a leader in international research. He worked for 24 years at MIT before moving to Oxford. He later joined the University of Texas at Austin in 1986. He held the Virginia H. Cockrell Centennial Chair in Engineering. Even at age 98, he continued to search for new breakthroughs. He remained active in research until very late in his life.
His contributions earned him many of the world's highest scientific honors. He received the National Medal of Science in 2013. He also won the Draper Prize in 2014. In 2001, he was awarded the Japan Prize for his battery research. The Nobel Prize in Chemistry was shared with M. Stanley Whittingham and Akira Yoshino. 
Goodenough's work connects deeply to the global effort for sustainable energy. He wanted to reduce human dependency on fossil fuels. To do this, he focused on improving electric vehicle technology. He even explored the idea of a "glass battery." This would be an all-solid-state battery using glass electrolytes. Such a battery would be noncombustible and charge very quickly. While this specific idea faced skepticism from other scientists, it shows his drive to innovate. His life's work helped build the foundation for a cleaner, more mobile world.
