[Featured Stock] Isu Specialty Begins Full-Scale Production of All-Solid-State Battery Materials... 'Aiming to Become a Global Leader'

The stock price of Isu Specialty Chemical is on the rise. The news that the company will invest 300 billion KRW in Gumi starting next year to build a production plant for lithium sulfide (Li2S), a key raw material for all-solid-state batteries, appears to be influencing the stock price.

As of 9:36 AM on the 18th, Isu Specialty Chemical is trading at 371,500 KRW, up 8.47% compared to the previous trading day.

Gyeongbuk Province, Gumi City, and Isu Specialty Chemical signed a Memorandum of Understanding (MOU) on the 15th at Gumi City Hall for the establishment of a new factory within the Gumi National Industrial Complex.

Isu Specialty Chemical, a precision chemical company spun off from Isu Chemical, an affiliate of the Isu Group, has made an investment to expand its lithium sulfide demo plant to meet increasing customer demand. Full-scale product mass production is expected to begin as early as the first half of this year. The MOU is regarded as a significant step toward the commercialization of lithium sulfide. Isu Specialty Chemical aims to quickly secure the investment site and start mass production by 2027.

Lithium sulfide is a key raw material that constitutes the solid electrolyte of all-solid-state batteries. Due to the complexity of the manufacturing process, mass production is difficult, and only a few companies possess the necessary technology. Ryu Seung-ho, CEO of Isu Specialty Chemical, stated, "This is the first step toward becoming a world-leading supplier of lithium sulfide," and added, "We will lead the industry in both the quality and quantity of lithium sulfide and strive to accelerate the commercialization of electric vehicles equipped with all-solid-state batteries."
