As the most important portable energy source, lithium batteries affect every aspect of our lives.
Without a lithium battery, there would be no portable wearable devices available today. The lithium battery industry is close to an annual production of billions of dollars, providing power for human daily activities. Lithium batteries have also been regarded as the greatest inventions in the electronics industry along with transistors.
According to public information, American scientist John B Goodenough is a professor at the Department of Mechanical Engineering at the University of Texas at Austin. He is 97 years old and a famous solid physicist. He is the inventor of lithium cobaltate, lithium manganate and lithium iron phosphate cathode materials. One of the founders of ion batteries, designing new materials to solve material science problems by studying the relationship between chemistry, structure, and solid electron/ion properties.
In 1979, Goodenough discovered that lithium cobalt oxide (LiCoO2) was used as the cathode of the battery, and a metal material other than lithium was used as the anode, enabling high-density energy storage. This discovery paved the way for the development of lithium-ion batteries, leading to the widespread use of rechargeable lithium-ion batteries. His research has made lithium batteries smaller, larger, and more stable, which has led to commercialization and the opening of electronic devices.
