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. When processing and producing lithium battery electrode materials, they need to be mixed first, and the processing of lithium battery electrode materials usually uses a raw material mixing device to mix the electrode materials.
