Designed to establish an ultra-stable, repeatable electrical interface, this fixture eliminates contact inconsistencies and parasitic resistance that frequently compromise electrochemical data integrity during cell characterization.

Optimized for both ambient and extreme environmental chamber testing, the fixture accommodates high-throughput coin cell testing across research institutions, gigafactory quality control laboratories, and materials development facilities. Its robust construction ensures continuous operational reliability across wide thermal operating regimes without contact degradation or mechanical fatigue.

Manufactured with premium contact metallurgy and high-grade, flame-retardant structural materials, this test fixture provides industrial-grade durability and signal fidelity. It withstands aggressive cycling protocols and high-current transient loads, giving battery researchers and test engineers total confidence in their quantitative data reproducibility.

Key Features

• Ultra-Low Contact Resistance: Engineered with high-conductivity contact interfaces that maintain a contact resistance of ≤1mΩ, eliminating measurement artifacts, parasitic voltage drops, and thermal hotspots during high-rate charge and discharge cycles.
• Extended Operating Temperature Range: Thermally stabilized housing and resilient spring-loaded contacts maintain mechanical elasticity and electrical performance across a wide operating envelope of -55°C to +125°C, making the fixture ideal for environmental chamber thermal profiling.
• High Current Handling Capability: Designed to support a steady-state continuous current of ≤5A and withstand transient peak loads up to ≤10A, facilitating rapid high-C-rate pulse testing, fast-charging evaluations, and short-circuit simulation studies without thermal distortion.
• Superior Dielectric Isolation: High-performance insulation delivers reliable dielectric isolation up to 500V DC (≤1×10⁹Ω), ensuring absolute channel-to-channel isolation and zero cross-talk during multi-channel battery analyzer integration.
• Exceptional Mechanical Endurance: Precision-engineered contact mechanisms and durable structural polymers provide an extended operational lifespan of 20,000 to 50,000 insertion and clamping cycles, drastically lowering long-term replacement costs in high-throughput screening environments.
• UL94V-0 Certified Flame Retardancy: Built with industrial-grade grey polymer compliant with UL94V-0 flammability standards, preventing combustion and enhancing laboratory safety during unexpected thermal runaway or overcharge incidents.
• Consistent Clamping Pressure: Uniform spring tension across the full lifecycle ensures steady, repeatable mechanical pressure on coin cell terminals, preventing interfacial delamination or intermittent contact errors during long-term cycling.
• Corrosion-Resistant Contact Surfaces: Surface-treated contact points resist oxidation and chemical degradation caused by trace electrolyte vapor, preserving electrical conductivity and measurement accuracy over prolonged multi-month testing campaigns.
