There are two types of lithium batteries:
Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Lithium metal batteries are disposable batteries that cannot be charged.
A non-rechargeable battery is called a disposable battery. It can only convert chemical energy into electrical energy at one time, and cannot restore electrical energy back to chemical energy. Such as lithium-manganese dioxide primary battery, lithium-thionyl chloride primary battery.
A rechargeable battery is called a secondary battery (also called a battery). It converts electrical energy into chemical energy and, when used, converts chemical energy into electrical energy. It is reversible, such as the lithium-ion mobile phone battery that is common on the market.
