Lithium battery is widely used in portable electronic devices, electric vehicles, energy storage systems and other fields. According to its working principle and structure, lithium battery can be divided into lithium primary battery (non-rechargeable) and lithium secondary battery (rechargeable), among which lithium ion battery is the most common type of rechargeable lithium battery. Lithium ion battery slurry is composed of a variety of raw materials with different specific gravities and different particle sizes, and is a solid-liquid phase mixed dispersion. The slurry formed is a non-Newtonian fluid. It is very important to stir it evenly during its preparation process.
