Coin cell assembly is a crucial step in the fabrication of coin cell batteries. The following equipment is commonly used:

Coin Cell Cases: These are typically made of stainless steel or other suitable materials. They provide the structure and containment for the battery components.

Coin Cell Assembly Jigs: These jigs hold the components of the coin cell, including the electrode, separator, and electrolyte, in place during assembly. They ensure precise positioning and alignment.

Electrode Preparation Equipment:

Preparing the electrode materials is a key aspect of coin cell fabrication. The following equipment is used:

Coating Machine: This machine applies electrode materials, such as the anode and cathode, onto current collector foils. It ensures a uniform and precise coating thickness, which is essential for battery performance.

Drying System: After coating, the drying system removes solvents from the coated electrodes, ensuring proper adhesion and stability.

Electrode Cutting and Slitting Equipment:

To achieve the desired dimensions for the coin cell electrodes, the following equipment is employed:

Cutting Machine: This machine cuts the coated electrode sheets into the desired dimensions that match the size of the coin cell.

Slitting Machine: It divides the electrode materials into narrower strips for electrode winding or stacking.

Electrode Winding and Stacking Equipment:

The electrode winding or stacking process involves the following equipment:

Winding Machine: It rolls the positive and negative electrode strips together with separators to form tightly wound electrode assemblies, known as jelly rolls.

Stacking Machine: This machine stacks multiple layers of positive and negative electrodes, separated by electrolyte-soaked separator films, to create the final electrode assembly.

Coin Cell Testing and Characterization Equipment:

To evaluate the performance and characteristics of coin cell batteries, the following equipment is utilized:

Performance Testing Instruments: These instruments measure critical parameters such as voltage, capacity, internal resistance, cycle life, and self-discharge rate. They provide insights into the battery's performance and behavior.

Impedance Spectroscopy Analyzer: It analyzes the electrochemical behavior of coin cells by measuring their impedance response across a range of frequencies.

Differential Scanning Calorimetry (DSC): DSC analysis determines the thermal properties, including specific heat capacity, phase transitions, and reaction kinetics of the coin cell components.
