Slot coating is one of the most used coating methods in the industry. Especially in battery manufacturing, the coating of cathode and anode material called “battery slurry” is being actively researched because of its importance in the industry.Meanwhile, flow passing a slot die experiences both sudden expansion and contraction due to the geometry of the die cavity. This geometric characteristic is essential since it causes a pressure difference depending on the location. Furthermore, because it is a pressure-driven flow, the pressure difference determines the flow inside the cavity.This study will look at the pressure change inside a cavity when coating a battery slurry over time. We will look at several characteristics that battery slurry has and that die cavity has by analyzing the pressure obtained by two different methods: computer simulations and experiments. |
