Turin, Italy | May 22, 2025 – At the prestigious ALBA Workshop on 12V EV Lead Auxiliary Batteries in Turin, Italy, QuantumShield Technologies (QST) unveiled the remarkable advantages of its sodium-ion battery technology over conventional chemistries in cold-temperature performance.

As part of the ALBA Sensor Sub-Group session on Charge Recovery and Functional Safety Testing, QST’s team—including Eason Tu and Yuki Nagata—presented a comprehensive Charge Recovery (CR) and Peak Power Capability (PPC) testing methodology that compares sodium-ion, lithium iron phosphate (LFP), and lead-acid batteries under extreme conditions, including -18°C scenarios.

The results demonstrated that QST’s sodium-ion (SIB) cells consistently outperformed LFP cells, especially in critical low-temperature scenarios. Sodium-ion cells exhibited stable voltage profiles, minimal sensitivity to pulse duration, and faster recovery in state-of-function (SOF) tests compared to LFP cells, highlighting their superior cold-cranking ability. These findings underscore the potential of sodium-ion technology as a safer, more robust alternative for 12V automotive and auxiliary battery applications, particularly in harsh winter environments where traditional chemistries struggle.

“ALBA provides an excellent platform for industry collaboration,” said QST President Shawn Peng. “Our work demonstrates that sodium-ion technology is not just a laboratory concept—it’s a real, scalable solution that can meet global energy demands while enhancing cold-weather reliability.”

QuantumShield’s research, showcased in Turin, reinforces its commitment to sustainable energy solutions through innovative sodium-ion battery development. The company’s mission is to support industries ranging from automotive to renewable energy with safe, high-performance, and environmentally friendly energy storage solutions.
