Key Features & Advantages

Premium Imported Substrate: Formed using Japanese imported nickel-plated steel, promising excellent mechanical rigidity, pressure tolerance, and anti-corrosion properties under aggressive electrolyte environments.
Fail-Safe Pressure Relief: Integrates a precision-engineered aluminum burst disc that fractures along a predetermined trace when internal gas accumulation peaks, eliminating critical thermal runaway or explosion hazards.
Pre-Welded Tabs (Ready-to-Assemble): Caps feature 15 × 3 × 0.15 mm aluminum tabs pre-attached via professional spot welding, allowing researchers to bypass manual cutting or alignment and accelerating glovebox assembly.
Power-Type Ultra-Low Resistance: The 18#Z structured option completely removes current bottlenecks to reach a minimal impedance of ≤0.5 mΩ, making it ideal for high-rate charge-discharge profiles.
One-Stop Laboratory Kit Consolidation: Every pack is structured as a full 100-set kit including 100 steel cases, 100 anti-explosion caps, and 200 high-temperature insulation spacers to avoid multi-vendor component mismatch.

APPLICATION SCOPE: Cylindrical 18650 cell electrochemical evaluations, high-rate charge-discharge profiling, high-power battery materials R&D, and wearable device/IoT power module prototyping.

PACKAGING: 100 Sets / Pack (Includes 100 cases, 100 cap assemblies, 100 top gaskets, and 100 bottom gaskets securely packed in anti-static vacuum-sealed bags). Inquire for official pricing parameters at support@atomfair.com.

IMPORTANT NOTICE: Regulate storage between 0–35°C and ≤75% RH away from open flames or corrosive gases. Once the vacuum seal is broken, immediate usage is highly recommended to protect welding integrity from ambient humidity and prevent trace metal oxidation.
