As expectations grow for the commercialization of all-solid-state batteries, domestic secondary battery-related stocks are showing a collective rally. With next-generation battery technology emerging as a key factor in the future electric vehicle market, investors are focusing their attention on the growth prospects of related companies.

■ Market Trends... Samsung SDI, LG Energy Solution, and SK Innovation Rise Together

In the morning session on the 15th, both Samsung SDI and LG Energy Solution showed upward trends. Samsung SDI rose more than 3%, demonstrating strong momentum, while LG Energy Solution also recorded gains in the 3% range. SK Innovation surged over 6%, leading an improvement in investor sentiment across the secondary battery sector.

■ Why All-Solid-State Batteries Are the Next-Generation Core Technology

The market evaluates all-solid-state batteries as a next-generation technology that can overcome the limitations of existing lithium-ion batteries. The key advantage is that using solid electrolytes instead of liquid electrolytes can enhance safety and improve energy density. The industry expects this technology to play a crucial role in extending the driving range of electric vehicles and reducing charging times.

As global automakers expand their research and development investments to accelerate the adoption of all-solid-state batteries, competition in battery performance is intensifying. Accordingly, some analysts suggest that companies with secured related technologies could further strengthen their market dominance.

■ Interest Spreads to Materials and Equipment-Related Stocks

Samsung SDI is cited as a leading company actively engaged in the research and development of all-solid-state batteries. The industry is closely watching whether the company can develop prototypes and secure mass production technology, with the belief that its technological competitiveness will significantly impact its future corporate value.

Expectations for benefits are also extending to all-solid-state battery material companies. Companies such as ISU Specialty Chemical, Hannong Chemicals, Lake Materials, and Ducksan Techopia are frequently mentioned in the market, with ISU Specialty Chemical showing an upward trend. On the equipment side, CIS, Hanwha Machinery (Hana Technology), and Kowintech are expected to benefit from the expansion of next-generation battery production facilities.

■ Remaining Challenges Before Commercialization

Experts point out that there are still many challenges to overcome before the commercialization of all-solid-state batteries. They explain that issues such as reducing production costs, securing mass production technology, and improving lifespan remain, which means it may take time before actual market expansion occurs.

Nevertheless, the market sees a high likelihood that all-solid-state batteries will establish themselves as a central pillar of the future battery industry. Investors are expected to continue focusing on the technological development achievements and commercialization schedules of related companies, including Samsung SDI and LG Energy Solution.
