The pioneer to modern day energy!

John B. Goodenough helped create the lithium ion battery, the technology that powers modern portable life. Before lithium ion batteries, portable electronics were heavy, slow to charge and unreliable. Energy storage was the limiting factor. Goodenough believed batteries could be lighter and store far more energy if the chemistry was redesigned. In the late 1970s, he discovered that lithium cobalt oxide could dramatically increase voltage. This single change multiplied energy density. The idea was risky. Lithium is highly reactive. Early versions were unstable. Others refined the design, making it safe enough for every use. The breakthrough held Lithium ion batteries made laptops practical, then phones, then electric vehicles. They enabled wireless tools, medical devices and entire mobile industries. Goodenough did not build consumer products. He solved a materials problem that everything else depended on. In 2019, at the age of 97, he received the Nobel Prize in chemistry. The battery is rarely noticed, but without it, modern life would stop moving. Some inventions change the world quietly. They sit in your pocket and never ask for attention.
