Introduction To Lithium-ion Batteries

Lithium-ion battery is a secondary battery (rechargeable battery) that mainly relies on lithium ions to move between positive and negative electrodes to work. During the charging and discharging process, Li+ intercalates and deintercalates back and forth between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, intercalated into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true during discharge.
On October 9, 2019, the Royal Swedish Academy of Sciences announced that it would award the 2019 Nobel Prize in Chemistry to John Goodenough, Stanley Whittingham and Akira Yoshino in recognition of their contributions to the research and development of lithium-ion batteries .
From August 1, 2023, CCC certification management will be implemented for lithium-ion batteries and battery packs. From August 1, 2024, those who have not obtained the CCC certification and the certification mark are not allowed to leave the factory, sell, import or use in other business activities.
