304SS CR2450 Coin Cell Cases for Precision Battery R&D

304 Stainless Steel (304SS) CR2450 coin cell Cases, designed to address critical gaps in battery research hardware. Targeting laboratories and industrial developers, these cases combine superior material science with standardized form factors to accelerate innovation in next-generation energy storage systems.

Product Innovation & Technical Specifications

1. Robust 304SS Construction

Fabricated from corrosion-resistant 304 stainless steel—a material celebrated for its mechanical strength and oxidation resilience—the cases withstand harsh electrochemical environments. With 18-20% chromium and 8-10.5% nickel composition, 304SS offers exceptional resistance to acids and atmospheric corrosion, critical for maintaining purity in electrolyte testing.

2. Precision Dimensions & Sealing

Aligning with CR2450 battery standards (24.5 mm diameter × 5.0 mm height), the cases feature a two-part crimp design with integrated silicone O-rings. This ensures leak-proof containment of volatile electrolytes, while the standardized size guarantees compatibility with automated cell assembly tools.

3. Thermal Resilience

Engineered for stability across extreme temperatures (–30°C to 60°C), the cases support testing of batteries for applications ranging from arctic sensors to high-heat industrial equipment.

Key Advantages for R&D Efficiency

1. Enhanced Experimental Reproducibility: Eliminates hardware-induced variability, enabling reliable data comparison across labs.

2. Long-Term Durability: Resists degradation from repeated charge-discharge cycles, reducing replacement costs.

3. Contamination Control: 304SS’s low ion leaching minimizes electrode contamination, crucial for solid-state and lithium-metal battery trials.

4. Eco-Safe Profile: Mercury-free and leak-resistant, aligning with sustainable lab practices1.

Targeted Applications

1. Solid-State Battery Development: Secure sealing prevents electrolyte evaporation during high-temperature cycling.

2. Medical & IoT Device Power Sources: Validates coin cells for implantable sensors and remote monitors requiring ultra-stable voltage.

3. Academic Research: Simplifies prototyping for novel chemistries (e.g., silicon anodes, sulfur cathodes).

We also provide relevant cone springs (20*1.7mm) and spacers(20*0.4mm).
