Coin Cell Parts
Overview
Coin cell parts are the fundamental components used to assemble coin-type batteries for laboratory research, material evaluation, prototype development, and quality testing. Coin cells, also known as button cells, are among the most widely used battery formats in research laboratories due to their compact size, simple structure, low material consumption, and excellent repeatability. They are extensively employed in the development of lithium-ion batteries, sodium-ion batteries, solid-state batteries, lithium-metal batteries, zinc-ion batteries, and other advanced electrochemical energy storage systems.
A complete set of coin cell parts typically includes the cell case (cap and can), spacer, spring, sealing gasket, insulating ring, current collector, and optional accessories depending on the battery chemistry and cell configuration. These precision-engineered components work together to provide reliable electrical contact, airtight sealing, mechanical stability, and consistent electrochemical performance.
Manufactured from high-quality materials such as stainless steel, nickel-plated steel, polypropylene (PP), polyether ether ketone (PEEK), and PTFE, modern coin cell parts are designed to meet the stringent requirements of laboratory-scale battery assembly. They are compatible with standard coin cell sizes such as CR2016, CR2025, CR2032, CR2430, and customized research formats.
As battery technology continues to evolve, high-quality coin cell parts play an increasingly important role in ensuring accurate experimental results and accelerating the development of next-generation energy storage materials.

Key Characteristics
High-performance coin cell parts are manufactured with strict quality standards to ensure reliable assembly and consistent battery performance.
High Dimensional Precision
Coin cell components are produced using precision machining and stamping technologies with extremely tight dimensional tolerances. Accurate dimensions ensure proper alignment during assembly, improving sealing performance and reducing contact resistance.
Superior Corrosion Resistance
Most metal components are manufactured from stainless steel (such as SUS304 or SUS316), offering excellent resistance to electrolyte corrosion and oxidation. This helps maintain stable electrochemical performance throughout battery testing.
Excellent Mechanical Strength
The cell case, spacer, and spring are designed to withstand the pressure generated during crimping while maintaining structural integrity during repeated charge and discharge cycles.
Reliable Sealing Performance
High-quality sealing gaskets made from polypropylene, nylon, or PTFE provide excellent resistance to electrolyte leakage and moisture penetration, protecting sensitive electrode materials from contamination.
High Electrical Conductivity
Metallic components such as the cell cap, can, and current collectors provide low-resistance electrical pathways, minimizing energy loss and ensuring accurate electrochemical measurements.
Compatibility with Multiple Chemistries
Modern coin cell parts are suitable for assembling a wide variety of battery systems, including lithium-ion, sodium-ion, lithium-sulfur, solid-state, magnesium-ion, and zinc-based batteries.

Manufacturing Process
The production of precision coin cell parts involves several advanced manufacturing processes to ensure dimensional accuracy, material consistency, and long-term reliability.
Material Selection
Production begins with carefully selected raw materials according to the intended battery application. Common materials include:
* Stainless steel (304, 316)
* Nickel-plated steel
* Polypropylene (PP)
* PTFE
* PEEK
* Nylon
Each material is chosen for its mechanical strength, chemical stability, and compatibility with battery electrolytes.
Precision Stamping
Metal components such as the battery cap and can are manufactured using high-speed precision stamping equipment. Progressive dies ensure uniform dimensions and smooth edges while maintaining high production efficiency.
Deep Drawing
For battery cases requiring greater depth and structural strength, deep drawing technology is employed. This process produces seamless metal containers with excellent mechanical properties.
Surface Treatment
Metal parts may undergo surface polishing, ultrasonic cleaning, passivation, or nickel plating to improve corrosion resistance, cleanliness, and electrical conductivity.
Injection Molding
Insulating components and sealing gaskets are produced through precision injection molding, ensuring consistent dimensions and reliable sealing characteristics.
Quality Inspection
Every batch of coin cell parts undergoes comprehensive quality testing, including:
* Dimensional measurement
* Surface inspection
* Corrosion resistance testing
* Hardness testing
* Electrical conductivity verification
* Leak-proof sealing evaluation
* Cleanliness inspection
Strict quality control ensures that each component meets laboratory and industrial standards.

Coin Cell Assembly Process
The assembly of a laboratory coin cell follows a standardized procedure designed to produce reproducible and reliable electrochemical performance.
First, the stainless steel battery case is cleaned and prepared. The cathode electrode is placed inside the case, by the separator and electrolyte. Next, the anode material is carefully positioned on top of the separator. A spacer is inserted to distribute pressure evenly, while a spring provides continuous mechanical contact between the electrodes and the cell cap.
Finally, the sealing gasket is positioned around the edge of the battery case before the entire assembly is crimped using a precision coin cell crimping machine. The completed cell is then subjected to aging, electrochemical testing, and performance evaluation.
Proper assembly using high-quality coin cell parts is essential for minimizing internal resistance, preventing electrolyte leakage, and ensuring consistent experimental results.
