No Thermal Propagation Technology

• Background Problem: In EV/ESS, thermal runaway not only causes damage to life and property but also dramatically increases recall/insurance/regulation costs, and "Propagation" is a core mechanism that expands into large-scale accidents. • Limitations of existing methods: (1) Detection/blocking alone is not enough to completely prevent propagation, (2) materials, exhaust, and pack design must be organically linked, and (3) propagation testing/prediction is complex.

• CES/SamsungSDI explanation: Defines No‑TP as a "comprehensive safety technology" that prevents thermal propagation at the cell, module, and pack levels, and includes a thermal propagation prediction program for design and verification as a package. • (Based on press release) Aims to suppress propagation by combining safety materials and pack-level engineering such as gas vents.

• Adopters: Finished vehicle OEMs, ESS system integrators, large battery project clients (indirect) • B2C/B2B/B2G: Primarily B2B (+ public ESS may be B2G)

• Environmental/Regulatory Constraints: Safety regulations/testing standards of each country, OEM requirements, and manufacturing process change costs will determine the speed. • Industry/Market Scalability: Wide application range in EV and ESS, and the demand for "safety" is structurally strengthening.

• CES Award Context Evaluation: In the battery industry, 'safety' is the highest priority requirement for both the market and regulations, so the exhibition message is strong. • Technology Completeness: Expectations are high as the technology is presented from the perspective of 'mass production application' by a major manufacturer. • Market Expectations: High business connectivity due to strong demand from OEMs/regulatory agencies. • Overestimation/Underestimation Factors: Information asymmetry due to the possibility that detailed test data may be released on a limited basis, making external verification difficult.
