Dr. John Goodenough, the creator of lithium-ion batteries, died at the age of 100, the University of Texas at Austin (USA) announced. Batteries of this type are widely used in smartphones, laptops and electric vehicles.

Scientists have been researching lithium batteries for a long time, but only Dr. Goodenough made a major breakthrough. In 1980, at Oxford University, he developed a cathode with layers of lithium oxide and cobalt, which helped to provide high voltage and an acceptable level of safety.

The new type of battery turned out to have a higher capacity than its predecessors, the lead-acid battery (which continues to be used in cars) and the nickel-cadmium battery (used in portable electronics).

The technology didn’t gain ground until Dr. Akira Yoshino replaced raw lithium with safer ions. He built a new type of battery for the Asahi Kasei Corporation, and Sony began mass production of them in 1991. As a result, it became possible to create smaller phones and laptops with longer battery life, electric vehicles also became a reality.

Dr. Goodenough’s contributions are not limited to batteries. During his time at the Massachusetts Institute of Technology, he participated in the development of RAM memory technology for computers.

The professor continued to work until the age of 90, devoting his last years to a new generation of battery technology that promises a breakthrough in the field of renewable energy sources and electric transportation.

In wide circles, Dr. Goodenough’s name remains little known, but his merits have been recognized by numerous awards, including the Nobel Prize in Chemistry in 2019. In a few years, car manufacturers plan to phase out lithium-ion battery technology in favor of more -larger, more powerful and safer solid-state batteries.
