Samsung SDI

Samsung's battery arm, developing solid-state cells for Korea's humanoid supply chain

Samsung SDI is a Samsung Group battery maker developing high-density and solid-state "SolidStack" cells, and serves as a partner in Korea's humanoid supply chain.

As part of the Samsung Group, Samsung SDI brings deep materials science and manufacturing expertise to the battery market, producing lithium-ion cells for automotive, industrial, and emerging robotics applications. The company's SolidStack solid-state battery programme targets the higher energy density and safety margins that untethered humanoid robots demand. Samsung SDI's role in Korea's humanoid supply chain reflects a broader national effort to build a competitive domestic robotics ecosystem, with established battery makers providing the energy foundation. Its technology roadmap and group-level partnerships make it a key enabler for next-generation Korean humanoids.
