[Featured Stock] Aekyung Chemical Solves Silicon Anode Material Challenge... Develops High-Capacity Silicon-Based Anode Binder

Aekyung Chemical is showing strong performance. The news of successfully developing a high-capacity silicon-based anode binder appears to be influencing its stock price.

As of 1:26 PM on the 25th, Aekyung Chemical is trading at 20,700 KRW, up 16.23% from the previous day.

On the 25th, Aekyung Chemical announced that it is focusing on research and commercialization of secondary battery materials by leveraging its accumulated technology and know-how in the synthetic resin field. The company is continuously developing products that improve the shortcomings of existing secondary battery materials and enhance efficiency.

Aekyung Chemical explained that graphite anode materials, mainly used in secondary batteries, have the advantages of low cost and stable crystal structure, but their energy storage capacity is limited. Silicon anode materials, which add silicon to graphite to increase charging speed and capacity, have emerged. The company has succeeded in commercializing secondary batteries containing about 5% silicon anode materials. According to a global market research firm, silicon anode materials are expected to grow at an average annual rate of 70% until 2025, increasing their share of the total anode material market demand to 11%. However, it is pointed out that as the silicon content in silicon anode materials increases, the battery expands during charging and discharging, which can shorten its lifespan.

In response, Aekyung Chemical embarked on technology development to solve this problem and succeeded in developing a 'high-capacity silicon-based anode binder.' Performance tests confirmed that even when the volume of silicon-based anode materials changes during charging and discharging, the adhesion between components and the initial electrode structure are effectively maintained, thereby extending the battery's cycle life. The company has completed patent registration domestically and internationally and is conducting application tests with overseas companies in Vietnam, China, and other countries as well as in Korea.

Previously, Aekyung Chemical was the first in Korea to independently develop hard carbon-based anode material manufacturing technology in 2010 and began mass production, steadily dedicating itself to the business. Hard carbon anode materials focus on high output, and especially Aekyung Chemical’s products have structural stability added, making them suitable for eco-friendly vehicles such as electric and hybrid cars. Recently, driven by the commercialization trend of Sodium Ion Battery (SIB) using sodium as the cathode material, the company has been gaining new attention in the market.

An Aekyung Chemical official said, "We are focusing on restructuring our portfolio by expanding into new businesses including secondary battery materials to find future growth engines," adding, "Through continuous research and development efforts, we will produce and supply products that meet customer demands and establish ourselves as a company that grows together with our customers."
