Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
The Tesla electric car we know is a 18650 lithium-ion battery that is connected in series and parallel. As new energy vehicles become more popular, the power battery industry has become hot!
Below we will learn about the manufacturing process of lithium batteries in graphical form.
