Xpeng IRON robot's solid-state battery enters small-batch production

On October 28, 2026, XPeng Group Vice President Gu Jie stated at the SAECCE annual conference that the solid-state battery for the XPeng IRON humanoid robot has entered small-batch production and is now off the production line. The robot remains in a pre-SOP phase. Gu Jie described it as XPeng's first solid-state battery specifically designed for robots. Constrained by the robot's internal space, the battery features a high-energy-density design and redefined standards, incorporating heat runaway diffusion prevention capable of withstanding impacts and nail penetration tests. Earlier, at the 2025 XPeng Tech Day, the company announced that its new generation IRON humanoid robot would be the industry's first to adopt an all-solid-state battery.

On August 24, 2026, XPeng's robotics business closed its first funding round, raising over $900M at a post-money valuation exceeding $6.3B, setting a new single-round private equity financing record for China's embodied AI industry. On September 8, 2026, the XPeng robot production line officially commenced operations. The world's first high-end general-purpose humanoid robot completed automated final assembly and walked off the line independently, marking a key milestone in XPeng's transition from research and prototyping to manufacturing.

Looking ahead, XPeng plans to achieve mass production of its humanoid robots by the end of 2026 and begin deliveries in the first half of 2027. The rollout will initially target commercial scenarios such as showrooms and shopping malls, before gradually expanding into industrial and home environments.
