  • The Nobel Prize in Chemistry 2019 rewards the development of the lithium-ion battery, which "laid the foundation of a wireless, fossil fuel-free society." 

  • The lithium-ion battery is a lightweight, rechargeable and powerful battery that is now used in everything from mobile phones to laptops and electric vehicles. It can also store significant amounts of energy from solar and wind power, making possible a fossil fuel-free society. 

  • The foundation of the lithium-ion battery was laid during the oil crisis of the 1970s. 
    • M Stanley Whittingham, discovered an energy-rich material called titanium disulphide, which he used to make a cathode - the positive terminal - in a lithium battery. 

    • Sony released the first commercial lithium-ion batteries in 1991, based on Yoshino's configuration.
