Product details





 





Lithium Ion Coin Cell Preparation Equipment For Battery R&D


 




Coin Cell Preparation included Electrode Preparation, Cell Assembly and Battery Testing 3 Process.

Coin cell is also called Button Battery, distinguished from the appearance means that the appearance size is like a Small button batteries are generally larger in diameter, thinner in thickness, and smaller in size, so they are widely used in various Microelectronics.



 





Coin Cell Preparation Steps and Process Flow


 








































































Procedure

Process Flow

Recommend Equipment

 



Electrode Preparation

Furnace to sinter raw active material (Cathode & Anode)



Milling Machine to mill material to smaller particles



Mixer to mix active, conductive and binder material into paste within vacuum



Viscometer to measure the viscosity of the slurry with better coating effect, And record it, so that the battery slurry can be used in the next experiment, The material is adjusted to this viscosity.



Use the slurry filter device to filter out the slurry not less than 124μm



Coater to coat paste on current collector and attached Heater used to dry it



Rolling Press (Calendar) to roll the electrode to reduce thickness and increase density.



Vacuum Oven to bake the electrode to drive away moisture inside



Cell Assembly

Disc Cutter to cut single coated anode, cathode, and separator into disc shape



Move the Electrode, Separator and Electrolyte, Coin Cell Case into the Glove Box (H2O and O2 less than 1ppm).



Assemble the batteries in the order of stacking from bottom to top and inject Electrolyte (Negative Case > Spacer + Appropriate Amount of Electrolyte > Metal Lithium Sheet + Appropriate Amount of Electrolyte > A Layer of Separator + Appropriate Amount of Electrolyte > Positive Electrode + Appropriate Amount of Electrolyte > Spacer + Appropriate Amount of Electrolyte > Spring > Positive Case).



Crimping Machine to crimp the coin cell so that the battery core is sealed in the case



Battery Testing

Battery Analyzer to test battery capacity and cycle aging



Battery Internal Resistance Tester measure the battery internal resistance.




 



Vaccum Mixer, Electrode Coating Machine, Electric Rolling Press Machine, Coin Cell Disc Cutter, Coin Cell Crimping Machine, Battery Testing Machine are the main process for Coin Cell Preparation
