Product Options

Calender Material:

MSK-HRP-MR100DC is a UL/CSA ready electric rolling press with variable speed 24VDC gear motor and UL certified switch power supply, which can be used from 110V- 220VAC under Argon gas glovebox. It has dual rollers of 100 mm Dia. x 100mm width and is an ideal rolling press for preparing electrode sheets for Li-Ion batteries research after coating and drying. (Since 11/29/2016, MR100DC ceramic coated roller option is available.)

Ceramic Rollers      PTFE Rollers
  • Material: Made from hardened tool steel (RC > 62) with Cr electroplated coating
  • Roller diameter tolerance (TIR): <0.004mm
  • RA (Roughness Average): 0.4um
  • Never roll materials with hardness > 50HRC (benchtop rolling press is not suitable for calendering thick metals. For applications with such needs, please consult with MTI engineers.)
  • Optional Rollers:  Ceramically coated  rollers are available in the product option bar
    • Ceramic coated on hardened tool steel with HRC > 72,
      • The coating material: 97% is chromic oxide; 3% is Al2O3, CaO3, and MgO
      • This roller is specially designed for rolling Lithium metal sheets,
    • PETE rollers: Good for laminating Lithium foil with Copper foil
Roll to Roll System (Not included)

R2R device can be integrated with the calendering machine at extra cost to enable the automatic film unwinding -> winding after calendering. Please click underline to view product details.

Application Notes
  • MSK-MR100DC roller can be used under Ar or N2 gas glove-box
  • Must use acetone to clean and dry rollers' surfaces after each use to avoid rusting
  • Apply anti-rust lubricant on roller surface if the machine were to be unused for a long period of time
  • Never rolls materials with hardness > 50HRC
  • Min. thickness for each rolling is dependent on the materials. Here are some results from our test:
  • Please refer to this instruction on how to calculate rolling pressure from the roller gap (reference only)
Electrode Size Original thickness Finished thickness
LiFePO4 double sides 50mm Width x 260mm Length 0.205mm 0.09mm
LiMn2O4 double sides 50mm Width x 260mm Length 0.205mm 0.09mm
Copper foil + graphite (single side) 75mm Width x 240mm Length 0.09mm 0.04mm
  • If rolling Lithium metal foil,   high purity mineral oil shall be used as a lubricant to avoid Li sticks on the roller. Click the link below to learn how to clean mineral oil from sample

  • The machine is not designed for thick metallic material. Click pic left for the rolling machine for metal
  • In order to prolong the lifespan of the roller bearings, regular lubrication is recommended
  • Multi-step thickness calendering needed: While calendering the sample sheet, make each calendering decrement of 0.02mm compared to the sheet original thickness
  • Never calendering decrement over 0.02mm compared to original sheet thickness each calendering.
  • Must clean roller surface after each rolling and lubricate when not in use to avoid corrosion
  • it is not allowed to use any MTI product in any hazardous location, especially prohibited from using in Class I environments (flammable gasses & vapor)
