What is the definition of lithium ion battery?
Lithium-ion battery: It is a secondary battery (rechargeable battery) that relies on lithium ions to move between the positive and negative electrodes to work. During charging and discharging, Li+ intercalates and deintercalates 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 is generally made of a material containing lithium as an electrode, and is a representative of modern high-performance batteries. True lithium batteries are rarely used in everyday electronics because of their high risk.
