▌Equipment : Dry Room

▲Filmed from the outside to the inside, the drying room is filled with battery manufacturing equipment, currently situated in the International Building IB1202.

▲The drying room at National Taiwan University of Science and Technology can be controlled to achieve a minimum dew point below -75 °C, facilitating the synthesis of sulfide solid electrolytes.

Coin cells or pouch cells are composed of positive and negative electrodes, electrolyte, and separator. During the manufacturing process, each component must be in a low-humidity environment to ensure the purity of the electrolyte and the stability of electrode performance. The process includes coating, calendaring, and forming of positive and negative electrode materials, electrolyte injection, and sealing.

Sulfide solid-state batteries are a key option leading the future energy storage field, boasting advantages of high energy density and safety. However, their manufacturing process is more stringent, requiring completion under extremely low humidity conditions. The drying chamber at our center plays a crucial role in the production of button cells, pouch cells, and sulfide solid-state batteries. It not only ensures the quality and purity of materials but also serves as a critical location for large-scale battery production. It provides a practical introduction to how NTUST students and researchers manufacture advanced batteries in an industrial setting.

▼Controlled dry room humidity is a crucial facility, including a dehumidification wheel system.
