Thanks to CTOnews.com netizens West window past, Mr. Aviation, Snailwang, South China Daniel Wu for the delivery of clues! CTOnews.com, June 27, according to the University of Texas at Austin, Nobel laureate John Bannister Goodenough died on June 25, just a month before his 101st birthday.

John B. Gudinav is an American solid-state physicist, an important scholar in the secondary battery industry, and a professor of mechanical engineering and materials science at the University of Texas at Austin.

According to reports, John B. Gudinav is a pioneer in the development of lithium-ion batteries, and his technology now powers millions of electric cars around the world.

Gudinav was born in Germany in 1922, then grew up in the northeastern United States and attended Groton School in Massachusetts. In 1944, he received a bachelor's degree in mathematics from Yale University. After working as a meteorologist in the United States Army, Gudinave returned to the University of Chicago in 1952 to complete his master's and doctorate in physics. At the University of Chicago, he studied with Nobel laureates Enrico Enrico Fermi and John A. Simpson, both of whom were involved in the Manhattan Project. His doctoral supervisor is the famous physicist Clarence Zener.

According to the University of Texas at Austin, Gudinav identified and developed key cathode materials that power electronic products such as mobile phones, laptops and tablets, as well as electric and hybrid vehicles. In 1979, he and his team found that high-density energy storage could be achieved using anodes other than metal lithium by using lithium cobalt as the cathode of lithium-ion rechargeable batteries. This discovery led to the development of carbon-based materials that allow the use of stable and manageable negative electrodes in lithium-ion batteries.

CTOnews.com noted that Gudinav was the oldest Nobel laureate at the time of winning the prize (97), setting a new record for Arthur Yashkin (96). "this rechargeable battery lays the foundation for wireless electronics such as mobile phones and laptops," the Royal Swedish Academy of Sciences said at the award. "it also makes possible a world without fossil fuels, which has a wide range of uses, from powering electric cars to storing renewable energy."

▲ 2019 Nobel Prize winner in Chemistry in 1980, Gudinav recruited Japanese scholar Koichi Mizashima and others to jointly discover the cathode material of lithium-ion battery lithium cobalt (LiCoO2).

In 1983, Gudinav, M.Thackeray and others found that manganese spinel is an excellent cathode material. Manganese spinel has low price, stability and excellent conductivity and lithium conductivity. Its decomposition temperature is high, and its oxidizability is much lower than that of lithium cobalt. Even if there is a short circuit and overcharge, it can avoid the danger of combustion and explosion. Although pure manganese spinel weakens with charge-discharge cycle, this can be overcome by chemical modification of the material.

In 1989, Gudinav and A.Manthiram found that positive electrodes using polyelectrolytes (such as sulfate) would produce higher voltages because of the electromagnetic induction effect of polyelectrolytes.

In 2014, the National Academy of Engineering recognized Gudinav, Simisu, Rachid Yazami and Akira Yoshino as the pioneering and leading foundational work for modern lithium-ion batteries.
