• Easy touchscreen control
• Automatic assembly: assemble in sequence, injection of electrolyte, and sealing of cells
• Suitable for use in glove boxes and dry rooms ( Double-sided glove box is recommended)
• The amount of electrolytes and the number of injections are settable
• Equipped with a built-in vacuum pump
• Standard package for assembling half coin cell, while full cell assembly can be completed by replacing with customized feeding slots and switch operation mode in PLC software. 

• Single Phase AC110V, or 220±10%V AC, 50/60 Hz, 200 W

Assembling Sequence for Coin Cell

• For CR2032 coin cells, there are two assembling sequences are available (the positive assembling sequence is regarded as the default mode since Jan 2025):
  • Positive Assembling Sequence: "cathode case, cathode disc, separator, anode disc, spacer, spring, and anode case".            

• • Negative Assembling Sequence: "anode case, anode disc, separator, cathode disc, spacer, spring, and cathode case". 

• • Other series of coin cells are available upon request, please contact MTI for more information.
  • Different assembling sequences can be customized upon request.

• Approximately 40-65 seconds per cell (depends on the motor speed set)

• Pre-load material manually, then assemble coin cell automatically

• ±0.1mm accuracy

• Better than ±0.5mm

• Crimping pressure adjustable
• For the CR20 series coin cell, 500-700KG sealing pressure is recommended

• Input air pressure should be 60-80 psi.
• The connection tubing size is O.D. 8mm.
• An air compressor is highly recommended for pneumatic actions, but not included. pls order it from MTI or local stores)
• Note: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn the installation of a gas regulator.

• Equipped with a peristaltic pump with adjustable Injection volume

• One glass-made electrolyte injector is included
• Capacity: 100ml Max.
• Electrolyte injection times and position can be set in touch screen.

• CR2032 sealing die is included in the standard package, other sealing dies are available upon request
• 5000 sealing times Max.

• If any oxygen or humidity sensitive substances are used (eg: Li metal anode, solid or liquid electrolyte), a glovebox or dryroom is required. 
• Single-chamber glovebox VGB-6-LD should be considered, but dual-chamber VGB-6-II-LD will leave more spaces for operaiton.

• Electrolytes are highly corrosive materials; therefore, the die set must be cleaned with ethanol after each experiment to avoid any corrosion damage. 
• Please be aware that MTI is not liable for any losses/damages resulting from improper use, care and maintenance, or abuse of the product. 

• After coin cell assembly, the formation process is critical to forming the SEI layer and obtaining a stable OCV.
• Normally at least 3-5 cycles are required. 
• A flat rubber spring (CR20SPR-Rub) is beneficial to pressure distribution. Please read more details in "Bridging the Gap Between Pouch and Coin Cell Electrochemical Performance in Lithium Metal Batteries, DOI: 10.1149/1945-7111/ad2731"
