MSK-200-SH Tape Casting Coater with Heated Slot-Die and Fixed Gap Blade for Precision Lithium Film Production up to 350°C
The MSK-200-SH is engineered to facilitate the tape casting of lithium films onto copper foil substrates, a critical step in battery research and development. This system is designed to operate within an argon atmosphere glovebox to prevent oxidation and contamination of lithium. It enables the formation of uniform lithium films with thicknesses ranging from 15 to 50 microns, essential for advanced lithium battery electrode fabrication.
The coater integrates a heatable slot-die and a fixed gap blade mounted on a movable fixture with precision wheels. Molten lithium is extruded through the heated slot-die onto the copper foil, which is held firmly by a heated vacuum bed to ensure substrate stability. The heated blade then scrapes the molten lithium to form a consistent film as the fixture moves steadily across the vacuum bed. This process allows precise control over film thickness and uniformity.

대표적인 적용 분야
This coater is primarily used in lithium battery research for producing thin, uniform lithium metal films on copper foil substrates. It is suitable for experimental development of lithium electrodes requiring precise thickness control and uniformity under inert atmosphere conditions.
구성 및 작동 안내
The system includes a movable tape casting fixture with a lithium melting vessel, heatable slot-die, and fixed gap blade mounted on precision wheels. The vacuum bed incorporates a built-in moving mechanism and an oilless vacuum pump for substrate fixation. The control unit is integrated beneath the vacuum bed for compact operation.
Operation requires an argon atmosphere glovebox to prevent lithium oxidation. Pre-treatment of copper foil substrates by ozone cleaning or plasma etching is recommended to enhance lithium wetting. Users must optimize coating parameters experimentally, as success depends on material and process conditions.
