Samsung debuts first pouch solid-state battery prototype for humanoid robots

Samsung SDI has unveiled its first pouch-type all-solid-state battery prototype designed specifically for emerging physical AI systems such as humanoid robots. This battery will be showcased publicly for the first time at the InterBattery 2026 exhibition in Seoul. Unlike traditional lithium-ion batteries that use liquid electrolytes, Samsung’s solid-state battery replaces the liquid with solid materials, enhancing safety, energy density, and compactness. The pouch design caters to compact devices requiring lightweight components and flexible integration, addressing the unique power demands of robots that experience sudden spikes in energy consumption while maintaining reliability. Beyond robotics, Samsung SDI is also presenting advanced battery technologies aimed at AI infrastructure, including a high-power prismatic battery for uninterruptible power supply (UPS) systems in data centers. This U8A1 battery uses lithium manganese oxide chemistry to deliver improved safety, higher power output, and better space efficiency—about 33% more efficient than previous models—helping stabilize power during sudden AI computing demand spikes.
