This year, the Nobel Prize in chemistry has got to the developers of Lithium-ion or Li-ion battery. The laureates of the prize are John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino from left to right in the photo above.
Sara Snogerup Linse, one of the members of the committee for chemistry, said that “the laureates developed lightweight batteries with high enough potential to be useful in many applications. For example, the ability to store energy from renewable sources—the sun, the wind—opens up for sustainable energy consumption”.
In the early 1970s, Dr.Whittingham took the first step to make lithium-ion batteries because he had figured out that lithium would make a good anode because it released electrons easily. Thus, he developed the first functional lithium battery around 50 years ago. Then, around 1980 Dr. Goodenough predicted that lithium-ion batteries would have greater potential if the cathode were made with different materials, for example, cobalt oxide. Finally, Dr. Yoshino followed Goodenough’s step and showed that more complicated carbon-based electrodes could eliminate pure lithium from the battery entirely. Instead, the battery used only lithium-ions which it causes to become safer.
