What is a lithium-ion battery

Lithium ion batteries are a type of secondary battery (rechargeable battery) that primarily relies on the movement of lithium ions between the positive and negative electrodes for operation. During the charging and discharging process, Li+is intercalated and disembedded back and forth between the two electrodes: during charging, Li+is disembedded from the positive electrode, embedded into the negative electrode through the electrolyte, and the negative electrode is in a lithium rich state; When discharging, the opposite is true.
On October 9, 2019, the Royal Swedish Academy of Sciences announced that the 2019 Nobel Prize in Chemistry would be awarded to John Goodyear, Stanley Whittingham and Yoshino for their contributions to the research and development of lithium-ion batteries.
