MSK-HRP-1A Electric Hot Rolling Press with 4″ Width, Variable Speed, and 200°C Max Temperature for Battery Electrode Preparation
The MSK-HRP-1A is engineered to address the challenge of increasing active material density in lithium-ion battery electrodes after coating. It is particularly suited for use inside or outside glove boxes due to its argon gas compatibility and compact design. This hot rolling press enables researchers to precisely control electrode thickness and density, which is critical for battery performance optimization.
The press utilizes a pair of 96 mm diameter stainless steel rollers, each 100 mm wide, capable of heating up to 200°C for less than one hour, or 190°C continuously. Dual independent temperature controllers allow separate heating zones for the upper and lower rollers, ensuring uniform thermal treatment. The rolling gap is adjustable from 0 to 1.2 mm, with a mechanical dial gauge included for precise gap measurement. A high torque 24V DC motor with a 1:75 gear reduction drives the rollers, offering variable speed control up to 26 mm/s, displayed digitally for accurate monitoring.

대표적인 적용 분야
This hot rolling press is primarily used in lithium-ion battery research to increase electrode active material density after coating. It is suitable for pressing thin electrodes coated on copper, silver, or gold foils to achieve precise thickness reduction and improved electrochemical performance. The device is also applicable for research requiring inert atmosphere processing inside glove boxes.
구성 및 작동 안내
- Optional roll-to-roll system (MSK-HRP-04-RD) can be integrated for automatic film unwinding and winding.
- Roller surface must be cleaned with acetone after each use to prevent contamination and corrosion.
- Do not roll materials with hardness exceeding 50 HRC to avoid damage.
- Multi-step thickness reduction is recommended, with each decrement not exceeding 0.02 mm compared to original thickness.
- Heating beyond 200°C is not advised as it may deform rollers and affect accuracy.
- Apply anti-rust lubricant on rollers if the machine is idle for extended periods.
- Not suitable for use in hazardous or flammable gas environments.
