Coin cell crimpers are essential for assembling test cells in battery research and development, allowing researchers to accurately used to seal coin-shaped (button-type) electrochemical cells. This sealing is vital for preventing electrolyte leakage and protecting internal components from the environment, ensuring reliable and safe battery operation.
Using high-pressure hydraulic, pneumatic, or electric actuation, these tools deliver clean, consistent, and leak-free seals, which are crucial for reliable testing. Controlled pressure is applied to deform the outer casing edges around a gasket and the internal electrode/separator stack. This creates a tight, continuous seal. Precise force is crucial to avoid damage or short circuits.
PI-KEM offers a range of hydraulic, pneumatic, electric, and automatic coin cell crimpers tailored for small-scale manufacturing, prototyping, and materials development. These systems support multiple coin cell sizes with interchangeable dies and are ideal for battery labs prioritising accuracy, repeatability, and ease of use.

Applications
Electrochemical Cell Assembly: Sealing new coin cells for testing novel electrode materials, electrolytes, and separators in various battery chemistries (e.g., lithium-ion, solid-state).
Material Characterization: Preparing standardized cells for electrochemical cycling, impedance spectroscopy, and performance evaluation.
Key Features & Options
Crimping Dies: Precision-machined molds (upper and lower) deform the coin cell casing to create the seal. Interchangeable dies allow crimping of different cell sizes.
Pressure Application System: Provides controlled mechanical force for crimping, via manual/hydraulic, pneumatic, or electric mechanisms, often with pressure gauges for accuracy.
Cell Holder/Alignment Mechanism: Ensures precise alignment of all coin cell components (electrodes, separator, gasket, casing) within the dies.
De-crimping: Some models allow safe opening of cells for post-mortem analysis.
Glovebox Operation: Some model can be operated within inert atmosphere glove boxes, essential for air-sensitive materials.
High-Throughput Automation: 16-channel automated coin cell assembly machine combines stacking cell components in sequence, injecting electrolytes, and sealing cells, with capacity for 40 cells/hour.
