ABSTRACT

According to the applicable conditions of coating quality of two different coating models in the extrusion coating of lithium battery, the flow state of the slurry in the inner flow channel of the extrusion die is simulated by Fluent software. The simulation results show that the coating uniformity of the two models basically meets the requirements. The FLUID1 die is superior to the FLUID2 die in terms of speed uniformity and loss. From the analysis of the uniformity of the outlet pressure, the FLUID1 pressure uniformity at the outlet is excellent with FLUID2.However, when considering the overall compression of the die, FLUID2 can also be selected. The suitable coating style depends on the different craft and coating skill.
