[Featured Stock] Seokyung AT Rises as Next-Generation Secondary Battery Material Stock... Developing 'Challenger' Following All-Solid-State Electrolyte

Seokgyeong AT is showing strong performance. The stock price appears to be influenced by news that the company has completed the development of a new lithium-ion solid-state electrolyte and is jointly developing conductive materials to enhance the lithium-ion conductivity of solid-state electrolytes with major companies.

As of 2:15 PM on the 20th, Seokgyeong AT is trading at 47,250 KRW, up 10.01% compared to the previous trading day.

Choi Jae-ho, a researcher at Hana Securities, explained, "Seokgyeong AT is currently jointly developing conductive materials with major companies to increase the lithium-ion conductivity of solid-state electrolytes." He added, "The spaces between particles in solid-state batteries are irregular, causing interfacial issues. To address this, conductive materials will be included alongside solid-state electrolytes in the production line of the third factory, which is scheduled for expansion this year."

Researcher Choi analyzed, "The expansion of the third factory is expected to accelerate from the second half of this year," and "production capacity will increase up to five times compared to the first and second factories through this expansion." He emphasized, "It is expected to be fully operational from the second half of next year," and "sales related to solid-state batteries are expected to be reflected as early as the second half of next year."

Choi also stated, "Solid-state batteries are expected to be commercialized as early as 2027," but added, "the demand for electrolytes for research and development is already high." He explained, "This is also why companies like POSCO Group, Samsung SDI, and EcoPro BM are establishing solid electrolyte production lines," and said, "This is the reason to pay attention to Seokgyeong AT, which is preparing for the development and mass production of innovative solid-state electrolytes that overcome the drawbacks of sulfide-based materials."

‘Boracite,’ a core technology secured by Seokgyeong AT, recorded a lithium-ion conductivity higher than that targeted by liquid electrolytes for solid-state electrolytes. The raw material cost is about 30% lower compared to sulfide-based raw materials. Another advantage is that harmful compounds such as hydrogen sulfide, which are considered drawbacks of sulfide-based solid-state electrolytes, are not generated, eliminating the need for large-scale facility investments like dry rooms. Researcher Choi emphasized, "The nano technology possessed by Seokgyeong AT is key," adding, "Through size and particle shape control technology and synthesis technology, they have achieved high conductivity, productivity, and stability, breaking through the limitations of existing materials."

He expressed expectations, saying, "Mass production preparations will begin this year," and "this marks the starting point for the secondary battery business alongside existing businesses."
