According to the industry on the 2nd, the Korea Battery Industry Association will hold InterBattery 2026 from the 11th to the 13th at COEX in Seoul. The exhibition theme is “Original Innovator, Creating the Future of Energy.”

LG Energy Solution said it plans to highlight growth drivers beyond electric vehicles, including ESS and robotics, and present itself as an innovator providing future energy solutions tailored to customer needs.

Its exhibit is organized into five areas, starting with a “hero zone” on battery history and future vision, followed by sections on energy infrastructure, mobility, robotics and drones, and future technologies.

LG Energy Solution plans to unveil ESS solutions optimized for power grids, along with an LFP-based next-generation rack system for JP6 UPS use in AI data centers and a BBU solution using high-output cylindrical batteries. It will also show examples of finished products using its batteries in robotics and drones.

SK On, which won more than 50% of volumes in a roughly 1 trillion won secondary ESS central contract market, will also use the show to broaden its business into ESS and robotics and speed up portfolio expansion.

It will introduce a high-energy-density LFP pouch battery for ESS, aligning with rising demand for large-capacity cells as the global ESS market seeks lower component costs and higher output. SK On said it is also conducting R&D to raise LFP energy density from 350 to 450 Wh/L to about 500 Wh/L.

SK On will also display a robotics application: a Hyundai Wia autonomous mobile robot equipped with a high-nickel NCM battery. The robot is used at industrial sites, including Hyundai Motor Group Metaplant America, for logistics automation.

Its booth is divided into three zones: Leading Tech, Future Tech and Core Tech. The Leading Tech zone includes an “R&D studio” where visitors can experience battery design and manufacturing. The Future Tech zone will feature immersion cooling technology being co-developed with SK Enmove, along with ultra-fast charging technology that can charge a battery from 10% to 80% in seven minutes.

Samsung SDI will participate under the slogan “AI thinks, Battery enables,” presenting a vision it describes as turning AI’s imagination into reality.

The centerpiece of its exhibit is battery technology for data centers, a key infrastructure for the AI era. Samsung SDI will display battery solutions for UPS and BBU applications, emphasizing the role of ultra-high-output batteries in supporting “zero power gaps” for AI data centers.

It will also show the “Samsung Battery Box,” an integrated ESS battery solution focused on environmental performance and safety. Samsung SDI plans to introduce its all-solid-state battery technology and said it is developing all-solid-state batteries with mass production targeted for the second half of 2027, aiming to expand applications to humanoids, mobile robots and industrial robots.

POSCO Future M will also take part, showcasing next-generation cathode and anode materials. The company said it will highlight materials solutions tailored to the needs of devices such as autonomous-driving EVs, ESS and humanoid robots.

It will present development status and roadmaps for materials including an ultra-high-nickel cathode with nickel content raised to more than 95% to improve driving range and stability for autonomous EVs; LFP cathodes used in ESS and entry-level EVs for lower cost and longer life; and next-generation materials such as cathodes for all-solid-state batteries and silicon anodes, which the company said are drawing attention as potential game changers for emerging industries including robotics due to high energy density.

A battery industry official said the exhibition is expected to show the battery industry expanding from an EV-centered focus to future industries including AI infrastructure and robotics. “Visitors will be able to see battery technologies applied to future industries across various booths,” the official said.
