SAMSUNG SDI was named as finalist of the The smarter E AWARD 2025 in the Category "E-Mobility" for the application of its No Thermal Propagation Technology.
Compared to LFP (lithium iron phosphate) cells, cells with NMC chemistry (nickel manganese cobalt) are considered to be significantly more sensitive to thermal runaway. If a cell is damaged or heats up significantly (thermal propagation), the neighboring cells are usually also affected and, in turn, heat up significantly. Samsung SDI has now introduced a hardcase format battery concept for NMC cells, known as “No TP Technology”, which is designed to minimize the effects of thermal propagation. The concept primarily consists of cells with a pressure relief valve on the top, as is common with hardcase cells. The hot gas escaping from there is conducted through insulation on the battery cover, which in turn is designed to prevent the battery cover from burning through, to venting openings in the battery housing. Special insulation between the cells prevents the transfer of heat to neighboring cells. If a thermal runaway or thermal propagation is detected, the cooling system is also activated to cool the battery as much as possible. This is done via a cooling plate on which the cells stand. The effectiveness of the system has been proven through testing.
