Open Source Coin Cell Crimper
Coin-cell assembly is a critical step in battery research, where consistent sealing pressure is required to ensure reproducible electrochemical performance. Commercial coin-cell crimpers are widely used for this purpose; however, their high cost, limited customizability, and dependence on centralized manufacturing and supply chains can restrict accessibility, delay experiments, and hinder rapid iteration in research laboratories. To address these challenges, this work presents a low-cost, open-source laboratory press designed specifically for coin-cell assembly.
The developed press prioritizes precision and portability while maintaining sufficient mechanical rigidity for laboratory use. All structural and functional components are precisely defined in parametric CAD and fabricated from widely available 3D printing filaments, which provides customization for different coin-cell formats and experimental requirements. The modular architecture allows individual components to be replaced, reprinted, or modified without dependence on proprietary parts. This simplifies maintenance and supports long-term operation. Design files were developed using Onshape and are made openly accessible through a public repository.
