Research-Grade Core Quality Advantages

Uniform High-Precision Tolerance Control: All component dimensions strictly controlled within ±0.02 mm, ensuring perfect matching across different batches and components, completely eliminating assembly gaps and uneven pressure issues caused by dimensional errors.
Full Material Gradient Coverage: Provides a complete material selection from basic to high-end, allowing flexible selection based on corrosivity, voltage range, and testing precision requirements of your experimental system, avoiding experimental failure due to mismatched consumables.
Rigorous Electrochemical Compatibility Verification: All materials have undergone constant potential polarization, cyclic voltammetry, and other electrochemical tests to ensure no side reactions within a -0.5 V to 5.0 V voltage range, guaranteeing no interference with battery performance test results.
Standardized Batch Production: Fully automated production and quality control ensures highly consistent product performance within and across batches, effectively reducing experimental systematic errors.

APPLICATION SCOPE: Precision assembly and standardized testing for battery structures requiring tab welding, pilot-scale batch production, routine electrochemical testing, and wear-resistant battery R&D requiring high conductivity.

PACKAGING: 1000 sets/pack. 100% dimensional inspection, coating thickness verification, sealing performance testing, and appearance inspection before shipment, ensuring oil-free, burr-free, and impurity-free conditions. Can be used directly for battery assembly inside gloveboxes.

IMPORTANT NOTICE: This series is a one-stop assembly solution for coin cells dedicated to electrochemical research. Default accompanying accessories are made of 304 stainless steel. If other materials or special dimensions are required, please email inquiry@atomfair.com for customization.

This series is a one-stop assembly solution for coin cells dedicated to electrochemical research, comprehensively covering the three mainstream models CR2032, CR2025, and CR2016. It provides a full material and specification selection of three core components—positive/negative electrode cases, conductive spacers, and elastic springs.
