Samsung SDI has embarked on a collaboration with German automobile brand BMW and U.S. battery materials company Solid Power to develop solid-state batteries, often referred to as the "dream battery."

Samsung SDI announced on the 31st that it has signed a Memorandum of Understanding (MOU) with these companies to jointly pursue a technical verification project for the automotive application of solid-state batteries. Samsung SDI will utilize the solid electrolytes developed by Solid Power to create solid-state battery cells with enhanced energy density and safety. BMW plans to develop solid-state battery modules and packs based on these cells and proceed with demonstration. The ultimate goal of the three companies is to verify the actual performance of solid-state batteries by equipping BMW's next-generation test vehicles with them.

Solid-state batteries use solid electrolytes instead of the liquid electrolytes used in conventional lithium-ion batteries. They offer superior safety and higher energy density, resulting in lighter weight and longer driving range compared to lithium-ion batteries of the same capacity.

Samsung SDI stated, "The tripartite agreement with BMW and Solid Power is significant as it brings together the core technological capabilities of the three companies, specialized in battery cells, automobiles, and materials, to create a global value chain." The selection of Samsung SDI as BMW's battery partner in this collaboration is attributed to their long-standing partnership. Since BMW chose Samsung SDI as its electric vehicle battery supplier in 2009, the two companies have established a close cooperative relationship over a long period.
