EcoProBM is strengthening its collaboration with Samsung SDI to commercialize sulfide all-solid-state batteries by 2027.


On October 6, EcoProBM announced that it has signed a memorandum of understanding (MOU) with Samsung SDI to develop materials for all-solid-state batteries. The two companies plan to pursue joint research and development in this field.


They will collaborate from the early stages of development through quality evaluation and mass production system establishment, expanding their cooperation to include key materials such as cathodes and electrolytes for all-solid-state batteries.


Under the agreement, Samsung SDI will be responsible for developing all-solid-state battery cells and enhancing mass production technology, while EcoProBM will focus on developing core materials for these batteries.


All-solid-state batteries are next-generation batteries that use solid electrolytes instead of liquid ones. They are gaining attention as potential solutions for electric vehicles and humanoid robots due to their increased energy density and safety, often referred to as the 'dream battery.'


EcoProBM has secured its own process technology in the sulfide solid electrolyte field and operates a pilot plant with an annual capacity of 40 tons. The company is developing solid electrolytes based on powder control and quality management technology, while also working on cathode materials for all-solid-state batteries using high-nickel technology.


In August, EcoProBM was selected for the Ministry of Trade, Industry and Energy's 'Super Eul Project' for its sulfide solid electrolyte project.


The Super Eul Project is a research and development initiative that supports technology development for companies in materials, parts, and equipment that lead the global supply chain. The ministry plans to provide long-term research and development support of approximately 20 billion won per project over seven years to selected companies.


Last month, the Ministry of Trade, Industry and Energy identified all-solid-state batteries as a next-generation strategic technology in its 'Battery Industry Technology Roadmap.' The government aims to support commercialization through joint research and development and supply chain collaboration between cell and material companies.


In July, EcoProBM revealed its plans to establish a full value chain for all-solid-state batteries during a corporate briefing.


Public Relations Director Gong Bo-hyun stated at the time, "We are currently reviewing pilot production with major clients, and we expect the earliest mass production to be in 2027. We are preparing to finalize the design of the production line and commence construction to meet customer demand."
