Sigitronics (CEO: Gyu-Hwan Shim) , a domestic semiconductor sensor company, and Yonsei University's Department of Materials Science and Engineering (Professor Woo-Young Lee, Underwood Distinguished Professor) announced on the 1st that they signed a memorandum of understanding (MOU) with the goal of establishing a strategic cooperation system for commercializing early detection technology for lithium-ion battery thermal runaway.
This collaboration is based on technology for detecting ultra-trace hydrogen levels in the sub-ppm (10⁻⁶ or less) range and sensing ultra-trace hydrogen (H₂) generated during the initial battery degradation reaction. This will provide battery safety monitoring solutions required for high-performance electronic systems such as electric vehicles (EVs) and energy storage systems (ESS), and promote the commercialization of innovative technologies capable of predicting thermal runaway from minutes to tens of minutes in advance.
Professor Lee Woo-young explained, “Existing commercial sensors have been unable to detect early hydrogen release signals due to limitations in their ppm-level sensitivity.” He added, “Yonsei University’s technology has sub-ppm sensitivity, ultra-fast response, and low-power characteristics, and can be combined with Edge AI to change the paradigm of battery safety technology.”
Sigitronics is a rare domestic sensor foundry that possesses both MEMS-based sensor semiconductor manufacturing lines and packaging infrastructure, enabling it to deliver highly reliable manufacturing capabilities capable of supplying products for the defense industry. A Sigitronics representative stated, "Combining Yonsei University technology with our semiconductor processing and packaging capabilities will enable us to rapidly commercialize world-class battery safety sensor modules. We plan to expand into all markets requiring fire prevention, including not only EVs and ESS, but also drones, smart factories, and data centers."
