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 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 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
  • This rolling press can be used to make free-standing 2D metal nanosheets by a repeated process of folding and calendaring stacked metal sheets (See reference below)
  •  Reference Articles: 2D Metals by Repeated Size Reduction

  • The rolling 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 comparing to sheet original thickness.
  • Never calendering decrement over 0.02mm comparing to original sheet thickness each calendering.
  • Must clean roller surface for each rolling and use acetone to clean and lubricate when not in use to avoid corrosion
  • it is not allowed to use any MTI product in any hazardous location, especially prohibit from using in Class I environments (flammable gasses & vapor).
