Lithium Ion Battery
It is a secondary battery (rechargeable battery) that mainly relies on lithium ions moving between the positive and negative electrodes to work. During charge and discharge, Li+ is intercalated and deintercalated between the two electrodes: when charging, Li+ is deintercalated from the positive electrode, and the electrolyte is embedded in the negative electrode, and the negative electrode is in a lithium-rich state;
Lithium batteries are classified into lithium batteries and lithium ion batteries. Both mobile phones and laptops use lithium-ion batteries, which are commonly referred to as lithium batteries. The battery generally uses a lithium-containing material as an electrode and is representative of modern high-performance batteries. True lithium batteries are rarely used in everyday electronics because of their high risk.
