According to Samsung SDI on March 12, Hyun Jangseok, Executive Director of the Strategy Marketing Division, stated at "The Battery Conference (TBC)," a side event of "InterBattery 2026" held at COEX in Seoul on this day, "All-solid-state batteries offer absolute safety while enabling lightweight and high energy capacity. They are an innovative solution capable of extending robot operation time up to eight hours." He further stressed, "All-solid-state batteries will be the ultimate game changer in the era of humanoid robots."

Executive Director Hyun also highlighted Samsung SDI’s technological competitiveness, mentioning the company’s all-solid-state battery brand, "SolidStack," which was unveiled for the first time the previous day. He explained, "We have established unrivaled technological prowess in the global industry, having filed around 1,000 patents and registered over 500 patents in the all-solid-state battery field." He added, "We plan to complete preparations for mass production of all-solid-state batteries by next year and to set the standard for battery technology in the global robotics market."

He also shared his outlook for the growth of the global robotics market. According to Executive Director Hyun, demand for service robots, which stood at around 500,000 units last year, is expected to increase to 2.04 million units by 2030. The average annual growth rate is projected to be approximately 32%, with humanoid robots expected to account for about 1 million units.

Samsung SDI identified four key elements for robot batteries: high energy density and fast charging, high output, safety, and design flexibility. The company stated that it is focusing on advancing cylindrical batteries, developing flexible pack designs, and securing thermal diffusion blocking technology to realize these features.

In addition, Samsung SDI explained that it is responding to the era of physical AI by supplying cylindrical batteries incorporating next-generation technologies—including high-nickel NCA (nickel, cobalt, aluminum) cathode materials, silicon-graphite composite (SCN) anodes, and high-output tabless structures—to global robotics companies, as well as developing all-solid-state batteries.

Executive Director Hyun stated, "Samsung SDI has proactively secured patents related to next-generation core materials," adding, "We have established a robust patent portfolio, holding over 700 patents just in the field of cylindrical battery components."

He continued, "With the recent rapid advancement of AI technology, the era of fully autonomous robots is now in full swing. Samsung SDI aims to lead the present and future of the physical AI era through high-performance battery solutions optimized for robots and to secure a leading position in the global market."

At "InterBattery 2026," which opened the previous day, Samsung SDI unveiled to the public for the first time a sample of its pouch-type all-solid-state battery "SolidStack," which is under development for physical AI applications such as humanoid robots, thereby highlighting its technological capabilities in all-solid-state batteries.
