Samsung SDI is collaborating with German automaker BMW and American 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 technology 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. Based on this, BMW plans to develop solid-state battery modules and packs for demonstration purposes. The ultimate goal for the three companies is to verify the actual performance of solid-state batteries by equipping them in BMW's next-generation test vehicles.

Solid-state batteries use solid electrolytes instead of the liquid electrolytes used in conventional lithium-ion batteries. This enhances battery safety and increases energy density, resulting in a lighter battery with a 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." They also emphasized that BMW's selection of Samsung SDI as a battery partner for this collaboration was greatly influenced by the trust built through a 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 the years.

Ko Joo-young, Vice President and Head of Samsung SDI's ASB Commercialization Promotion Team, stated, "The technological competitiveness of batteries directly leads to innovation in electric vehicles," and added, "We will continue to closely collaborate with excellent global partners like BMW and Solid Power to lead the commercialization of solid-state batteries."

Martin Schuster, BMW Group's Executive in charge of Battery Cell and Cell Module, said, "With Samsung SDI's participation, we can further accelerate the development of next-generation battery cell technology," and added, "This global collaboration will once again demonstrate BMW's ultimate goal of providing cutting-edge battery technology."
