On July 3, news emerged that Samsung SDI plans to invest a total of 25 trillion Korean Won by 2040 to establish a presence in next-generation battery technologies. Among this, 16 trillion Korean Won (approximately 70.88 billion yuan) will be allocated to build production lines for all-solid-state batteries, as well as lithium iron phosphate batteries for energy storage and sodium batteries, in Ulsan, South Korea. Another 9 trillion Korean Won will be invested in the Cheonan factory, transforming it into a research, development, and manufacturing center for next-generation batteries. Samsung SDI aims to achieve the commercialization of solid-state batteries in South Korea by 2027. Samsung SDI has also finalized plans to establish a sodium-ion battery production line in Ulsan, a project previously in the feasibility assessment stage for mass production.
