Gasgoo Munich- On July 30, Samsung SDI officially unveiled its commercialization timeline for all-solid-state batteries, planning to kick off mass production at its Ulsan plant in South Korea during the second half of 2027. The goal is to become the first domestic battery maker to bring solid-state technology to market.Image Source: Samsung SDIEarlier this month, Samsung SDI laid out a 14-year investment blueprint spanning 2026 to 2040, pledging a total of 25 trillion won (approximately 110 billion yuan) to its Ulsan and Cheonan manufacturing hubs. Of that, 16 trillion won is earmarked for the Ulsan complex to build production lines for all-solid-state batteries, lithium iron phosphate (LFP) cells for energy storage systems, and sodium-ion batteries. Another 9 trillion will expand the Cheonan facility, which serves as a technology verification center. Its dry electrode pilot line is already operational, laying the groundwork for cost reductions at scale.On the production readiness front, Samsung SDI has constructed a 6,500-square-meter S-Line pilot line at its Suwon R&D center, completing several rounds of formulation and process validation. The upcoming Ulsan line will directly inherit these pilot results for mass production. Technologically, the company is betting on sulfide-based solid electrolytes, with a previously announced energy density target exceeding 900 Wh/L.Samples of the all-solid-state batteries have already been delivered to potential customers in sectors like electric vehicles, embodied AI, and humanoid robots for performance evaluation. Samsung SDI plans to achieve commercialization domestically first, then gradually replicate that capacity at overseas factories once the scaling model is proven.The year 2027 has emerged as a critical milestone for the global solid-state battery industry. Rivals including Toyota, Geely, Chery, and BYD are all targeting a similar timeframe to roll out the technology.
