Coin Cell Manufacturing Equipment and Guide

To learn more about the Coin Cell Manufacturing process, click the steps listed below.

Step 1: Electrode Sheet Preparation
  • Use furnace to sinter raw cathode active material and anode active material.
  • Mill battery materials into smaller particles using milling machine.
  • Use mixer to mix active, conductive and binder material into paste under vacuum.
  • Using coater, coat paste onto current collector to make electrodes.
  • Dry the newly-created electrodes using a heater.
  • Use the rolling press (calendar) to roll the electrode to desired thickness.
Step 2: Li-ion Cell Assembly
  • Use Disc Cutter to cut single coated anode, cathode and separator into disc shape.
  • Use a Pressing Machine to flatten the disc.
  • Soak discs into electrolyte in glove box with H2O and O2 below 1ppm.
  • Stack the discs in the order found in the coin cell case.
  • Dry the cell using a vacuum oven.
  • Fill the appropriate amount of electrolyte into the case using Electrolyte filler.
  • Use a Crimping Machine to crimp the coin cell to seal the battery core within the case.
Step 3: Li-ion Battery Testing
  • Test the li-ion coin cell’s performance using the battery analyzer.
  • Measure the battery’s internal resistance using an impedance testing tool.
Working closely with our supply partners and organizations including the Electrochemical Society and NAATBatt International, we help lithium-ion battery manufacturers and researchers worldwide commercialize ambitious new technologies for the energy storage market. Contact us today to learn more.
