QuantumShield’s 2.2Ah Sodium-Ion Pouch Cell Passes Critical Safety Tests at US Independent Laboratory.

Issue 9 (April 23rd, 2025)

Claremont, CA | April 23, 2025 – QuantumShield Technologies is proud to announce that its 2.2Ah sodium-ion pouch cell has successfully passed a comprehensive set of critical safety tests conducted by Applied Technical Services (ATS), a leading US-based, ISO/IEC 17025-accredited laboratory located in Phoenix, Arizona.

The rigorous testing, performed between April 9 and April 18, 2025, included industry-standard assessments such as nail penetration, external short circuit, crush, overcharge, and forced discharge conducted in accordance with internationally recognized standards (UL1973, UN38.3). The results demonstrate the exceptional safety profile of QuantumShield’s sodium-ion technology, as all tests were completed without fire, smoke, or catastrophic failure.

Key findings from the ATS report include:

• No thermal runaway, ignition, or fire during or after extreme abuse scenarios.

• Stable cell behavior in nail penetration, with controlled voltage drop and temperature rise, peaking at 63°C.

• Resilience under external short circuit, crush, overcharge, and forced discharge conditions, with only expected mechanical deformation and no dangerous events.

• Demonstrated compliance with stringent US and international safety standards, providing a strong foundation for future sodium-ion battery commercialization.

  
  

“This achievement is a major milestone for QuantumShield and the sodium-ion battery industry at large,” said Shawn Peng, President and CTO of QuantumShield Technologies. “Our successful third-party validation in a US laboratory highlights the inherent safety and reliability of sodium-ion technology—a critical factor as we accelerate deployment into automotive and energy storage markets.”

QuantumShield remains committed to developing safer, greener, and more sustainable energy storage solutions, empowering industries to reduce reliance on critical materials while delivering high-performance alternatives for a net-zero future.
