Who invented LI-ION BATTERY

The Pioneers Behind Lithium-Ion Battery Technology

The Invention of Lithium-Ion Batteries

1. Early Developments:
   1. In the 1970s, British chemist Stanley Whittingham, while working for Exxon, first began exploring lithium batteries. He created a battery made from titanium disulfide and lithium metal. However, these early versions were too unstable and posed a risk of explosion when exposed to air.
2. John B. Goodenough’s Contribution:
   1. In 1980, John B. Goodenough, an American physicist and professor at the University of Texas, invented a more stable lithium battery using lithium cobalt oxide as the cathode material. This development significantly improved the battery’s capacity and stability, making it safer and more practical.
3. Akira Yoshino’s Commercialization:
   1. In 1985, Akira Yoshino of Japan assembled a prototype lithium-ion battery using lithium cobalt oxide as the cathode and petroleum coke as an anode. This version was capable of repeated charging and discharging, which was safer and more durable. Yoshino’s work is considered pivotal in advancing the battery toward commercialization.
4. Commercial Introduction and Patent:
   1. Based on these developments, the first commercially viable lithium-ion battery was released by Sony and Asahi Kasei in 1991. This launch marked the beginning of lithium-ion battery integration into consumer electronics, heralding a new era of portable electronic devices.
