On the 1st, IBK Investment & Securities predicted that Isu Specialty Chemical will make additional investments to build its first large-scale commercial plant by 2027.

Lee Dong-wook, a researcher at IBK Investment & Securities, stated, "Isu Specialty Chemical successfully operated a pilot lithium sulfide plant in collaboration with KBR," adding, "They have secured global top-tier new commercial process technology with enhanced cost competitiveness while pursuing further expansion."

He continued, "The 'PureLi2S' technology developed by Isu Specialty Chemical and KBR aims to produce lithium sulfide suitable for all-solid-state batteries," and added, "It is estimated to be the world's first to apply a continuous process, making it easier to transition to a mass production system."

He noted, "Quality and supply stability have been confirmed during the expansion," and expressed expectations that "the first large-scale commercial plant will be established in 2027." Furthermore, he emphasized, "When constructing a large-scale commercial plant, the capital expenditure per ton is expected to decrease significantly compared to the existing small-scale expansions."

The researcher analyzed, "The TDM expansion, with an investment of 13 billion KRW, will begin full-scale operation from the second half of this year," explaining, "TDM is a specialty niche chemical product that improves polymer polymerization processes and enhances performance through molecular structure modification." He explained, "By expanding production capacity from 20,000 tons to 30,000 tons, it will maintain a dominant market share not only domestically but also within the region."
