Samsung SDI announced it will present advanced battery solutions and new technologies for the AI era at InterBattery 2026, held March 11-13 at COEX in Seoul.
At this year’s exhibition, the company will unveil a pouch-type all-solid-state battery sample under development for physical AI applications such as humanoid robots. This product aims to provide greater safety and longer operational time, emphasizing Samsung SDI’s global leadership in all-solid-state battery technology.
Samsung SDI will also present battery solutions that boost reliability for energy storage systems (ESS) and provide more stable, high-power batteries for uninterruptible power supplies (UPS) and battery backup units (BBU). These solutions strengthen essential AI infrastructure by ensuring continuous operation and rapid response during power fluctuations.
United by the slogan “AI thinks battery enables,” Samsung SDI will have the largest booth, featuring innovative technologies and products.
Our goal is to show how Samsung SDI’s battery technology brings the complete potential of the AI era to life. A company official said, “With decades of expertise, we will present premium battery solutions designed for the changing needs of AI-powered industries.”
First Public Display of Pouch-Type All-Solid-State Battery for Physical AI
Samsung SDI will introduce its All-Solid State Battery technology at InterBattery2026. This technology, still in development, targets mass production in the second half of next year.
The company will show a pouch-type or solid-state battery sample for the first time, designed for new physical AI applications.
Robots have limited space for batteries and require small, lightweight cells with high energy density for long run times. They also need high power output during motion, so batteries must deliver it without overheating.
Samsung SDI is developing all-solid-state batteries that offer superior safety and high-power output for physical AI applications, using a pouch designed to reduce weight. After focusing on prismatic batteries for electric vehicles, the company now plans to offer a wider range of battery shapes for different applications, including humanoids, robots, aviation, and next-generation wearables.
To align with these technological advancements, this year’s exhibition theme is Inside AI, giving visitors an up-close look at how batteries are used in industries and everyday life.
The main booth will resemble a real IT data center, allowing visitors to feel like they are inside a working facility.
At the center of the booth, a US UPS mock-up will feature Samsung HDI’s U8A1 battery for UPS uses.
The U8A1 combines a unique prismatic shape and LMO chemistry for high power and safety. Designed for data centers, it offers greater energy density and volume efficiency for stable, rapid power delivery.
Unlike regular UPS batteries that only power during outages, the U8A1 also helps keep power steady during sudden spikes in AI power consumption. This feature enables continuous operation and prevents downtime, making it better suited to changing customer needs.
Behind the UPS area, Samsung SDI will debut its high-power BBU battery, installed in data center servers to provide instant backup during outages and prevent data loss.
The BBU uses high-nickel NCA cathodes (which store more energy) and SCN anodes (which allow faster charging) in a cylindrical battery. Annually, at the bottom, it helps release heat, reduces internal temperature, and extends battery life, enhancing overall safety.
By connecting high-power, high-capacity cells directly to servers, the system gives instant support during power peaks and can increase data storage time by over 50% during outages, enhancing operational continuity and protecting critical information.
Pop Art Collaboration With Um Jaewon And Exhibition Highlights
To begin, visitors can check out power tools that use Samsung’s HDI cylindrical batteries. This gives everyone a chance to see the company’s high-power cylindrical technology up close.
Samsung SDI’s cylindrical batteries use tapped technology, increasing power output and charging speed. For example, a circular saw with these batterie’s cuts wood faster and recharges in 15 minutes.
In addition to the technology displays, Samsung HDI is presenting five artworks created in collaboration with Korean artist Um Jaewon, inspired by the theme Fun-tastic Power: Energy that powers joy in everyday life. These pieces contribute a creative element to the exhibition. In his work, Um Jaewon portrays ESS as a quiet hero safeguarding sustainable energy in the AI era, and he represents Samsung HDI’s high-power batteries as small cells with significant potential, symbolizing how innovation can empower and enhance daily life.
