Sigetronics, a semiconductor sensor specialist, announced on the 1st that it has signed a strategic memorandum of understanding (MOU) with the Department of Materials Science and Engineering at Yonsei University for the commercialization of early-detection technology for thermal runaway in lithium-ion batteries.

This collaboration aims to commercialize an innovative technology capable of predicting thermal runaway several minutes to tens of minutes in advance, based on Sub-PPM (below 10⁻⁶) ultra-trace hydrogen gas detection technology and core sensing technology that detects minute hydrogen (H₂) generated during the initial degradation reaction inside batteries. The goal is to provide advanced battery safety monitoring solutions required for high-power systems such as electric vehicles (EVs) and energy storage systems (ESS).

Sigetronics is a sensor foundry company equipped with both a MEMS-based (micrometer-scale mechanical + electronic integrated system) semiconductor sensor manufacturing line and packaging infrastructure. It also possesses high-reliability manufacturing capabilities sufficient to supply products for defense applications.

A Sigetronics representative stated, “By combining Yonsei University’s world-class technological expertise with our semiconductor process, packaging, and module assembly capabilities, we expect to commercialize a global-level battery safety sensor module quickly,” adding, “We plan to expand beyond EVs and ESS to all markets requiring fire-prevention solutions, such as drones, smart factories, and data centers.”

Through this collaboration, Sigetronics and Yonsei University will fully pursue the commercialization of Korea’s first Sub-PPM-level hydrogen-based thermal-runaway prediction sensor. A first commercial-type sensor module prototype is scheduled to be unveiled in the first half of next year, followed by PoC (Proof-of-Concept) and joint verification projects with major domestic battery manufacturers and automotive OEMs. After 2027, the companies plan to expand supply to global OEMs and system providers and respond to standard certification requirements.
