Importance of Standardized 
Coin Cell Preparation in 
Battery Research
• Lithium-ion material evaluation relies 
on highly repeatable, contamination-
free Coin Cell preparation.
• Coin cells provide controlled 
geometry, consistent stack pressure, 
and minimal active material 
consumption.
• Ensures accurate comparison 
between batches, chemistries, 
binders, conductive carbons, and 
electrolytes.
• Serves as the foundational testing 
protocol before transitioning to 
pouch or cylindrical formats.
Breakdown of Coin Cell 
Components (CR20xx Families)
Primary coin cell components:
• Stainless steel top cap
• Stainless steel bottom case
• PP or PEEK sealing gasket
• Stainless steel spacers (varied thickness)
• Wave spring (predefined compression force)
• Anode & cathode punched electrodes
• Separator (PP/PE-based microporous films)
• High-purity electrolyte (carbonate, ether, ionic liquid, or solid-state compatible)
Note:
 R&D labs must source from a consistent coin cell case supplier to avoid variability 
in crimp sealing torque, indentation hardness, and electrolyte compatibility.
Coin Cell Preparation Equipment 
Required for High-Precision Workflows
• Slurry mixer (planetary, dual-axis centrifugal)
• Vacuum-grade doctor blade coater
• Film calendaring press (precision thickness control)
• Precision electrode punching system (±0.01 mm tolerance)
• Vacuum drying chambers (100–150°C continuous stability)
• Argon glovebox with
