SEOUL, Feb. 19 (Korea Bizwire) — Samsung SDI has completed the development of a breakthrough technology designed to prevent thermal propagation, a key cause of electric vehicle (EV) battery fires, and is now preparing for commercialization.
According to Samsung SDI’s newsroom announcement on February 18, the company has finalized the commercialization review for its ‘No-Thermal Propagation’ (No-TP) technology, which enhances battery safety by preventing the spread of heat within battery cells, modules, and packs.
The No-TP system employs advanced safety materials and an integrated cooling plate to physically block heat from spreading when a specific cell encounters an issue. This innovation allows for the replacement of only the affected cell or module, maximizing battery usability and longevity.
A key component of this technology is Samsung SDI’s proprietary ‘Thermal Propagation Calculator’ (TPc), which defines and quantifies heat propagation factors. The program automatically assesses the impact on adjacent cells when a failure occurs, enabling engineers to design battery structures optimized to mitigate thermal risks from the earliest planning stages.
No-TP technology is not limited to cell production; it is also applicable to module and pack assembly. Samsung SDI has already integrated TPc-optimized No-TP designs into its latest products, including the use of insulation materials between battery cells.
Additionally, Samsung SDI has adopted thermal barrier technology in its prismatic battery designs. The company utilizes a stacking method for electrode plates, which reduces internal pressure and allows gas generated during malfunctions to disperse in multiple directions, preventing excessive buildup.
Samsung SDI stated, “We remain committed to developing high-capacity, safe batteries and will continue advancing our technology to ensure the highest standards of EV battery safety.”
