Slurry Homogenization in Lithium-ion Battery Manufacturing Process Why focus on "homogenization"? If comparing lithium-ion battery manufacturing to baking a cake, slurrying is akin to "whisking egg yolks" - it appears to be a simple mixing process on the surface, but in reality, it determines the quality ceiling for subsequent coating and rolling processes, and even directly affects the battery's cycle life. Industry data shows that defects in the electrode sheets [...]
