Noble prize in chemistry- 2019 for lithium ion batteries

2019 Nobel Prize in chemistry is awarded jointly to three scientists Goodenough, Whittingham and Yoshino for the development of Lithium Ion battery which revolutionized the fueling , working and safety  of the gazettes like mobiles , tablets and computers.

 A lithium-ion battery or Li-ion battery is a secondary cell or rechargeable battery in terms of chemistry.

Primary cell or battery: The cell which cannot be reused once the reactants are finished or the reaction is completed.

Secondary cell or battery: The cell which can be recharged and reused by reversing the chemical reactions.  Once the chemical reactions are completed, the chemical reaction is reversed to get back the reactants by giving electricity to it which we call recharging.
