“…For the dewatering process, the power demand was calculated under the assumption that the vacuum pump used in this study follows isothermal compression, as the temperature change during the process is negligible . The power demand for isothermal compression was accomplished using eq P normali normals normalo = q normala normali normalr p normali normaln ln ( p o u t / p i n ) where, P iso represents the isothermal power demand [W].…”

Lithium-ion battery manufacturing is time-and energy-intensive because of the drying process. While current approaches aim to accelerate drying by reducing the amount of solvent, they compromise uniformity and pose challenges in mass production. This study introduces the dewatering concept, which is widely used in paper manufacturing, to the electrode manufacturing process and proposes a high-speed electrode manufacturing process applying dewatering (HEMPAD). It encompasses four sequential stages: casting battery slurries onto porous media, forming a filter cake through solvent dewatering, transferring the filter cake to a substrate, and subsequent drying of the filter cake. HEMPAD achieves a substantial reduction in processing time and energy consumption, effectively filtering out over 40% of the solvent during dewatering. The investigation encompasses an analysis of the microstructure and electrochemical properties under different negative pressures. The results reveal that HEMPAD, in the absence of negative pressure, displays a similar adhesion force and superior electrochemical performance compared to the conventional process. The introduction of HEMPAD in the electrode manufacturing process is promising for next-generation battery production as it enables faster drying speed, less energy consumption, and relatively stable electrochemical performance.

Upon the observation, small patches near the bottom of the vacuum container are found perforated in some situations, which severely affect the work efficiency and safety of the system. To investigate the mechanism of the damaging perforation, in this paper, a numerical method based on Fluent software is implemented to simulate wall shear stresses of the vacuum container. It is shown that the numerical method implemented accurately captures the flow pattern and the wall shear force distributions during the operation of the vacuum container. With such a simulation approach, the area prone to perforation can be effectively yet clearly identified and predicted. The wall shear stresses of the vacuum container are closely correlated with the inlet velocity. It is demonstrated that the wall shear stresses of the vacuum container tends to increase in magnitude with the increase of the inlet velocity.
