MSK-BPC-DF200 Three-Roller Hot Rolling Press with Asynchronous Speed Control for Dry Electrode and Solid-State Electrolyte Sheet Preparation
The MSK-BPC-DF200 is engineered to address the precise demands of lithium-ion battery research and development, specifically for producing dry electrodes and solid-state electrolyte sheets. It employs a continuous three-roller configuration where each roller’s speed and pressure can be independently adjusted, allowing for fine-tuned control over the rolling process to achieve uniform thickness and optimal material properties.
This model supports a maximum rolling width of 200 mm and can apply up to 10 tons of pressing force distributed independently across the three roller pairs. The rollers are made from hardened DC53 steel with a diameter of 150 mm and length of 220 mm, capable of operating at temperatures up to 150°C continuously. The roller gap is adjustable from 0 to 1.2 mm with a high precision of ±0.001 mm, ensuring consistent film thickness control.

Typische Anwendungsbereiche
This rolling press is ideal for fabricating dry electrodes and solid-state electrolyte sheets used in lithium-ion battery development. It supports roll-to-roll processing of spherical powder-based cathode electrodes and can be integrated with binder mixing and dispensing systems to ensure high-quality electrode formation. For lamination with current collectors, pairing with a roll-to-roll laminator is recommended.
Hinweise zur Konfiguration und zum Betrieb
An optional automatic powder feeder can be added to automate the powder feeding process, enabling fully automated roll-to-roll dry film preparation. Users ordering units before August 1, 2026, will require a software upgrade to operate this feature. The recommended working environment is a stable temperature of 25 ± 3°C without vibration or electromagnetic interference. Proper spherical powder and binder mixing are critical for optimal dry electrode quality. Manual adjustment of winding tension and speed is necessary to maintain film integrity during winding.
