XPeng vice president Gu Jie said the solid-state battery designed for the company’s IRON humanoid has entered small-batch production, Yicai reported on October 28, 2026. IRON itself is still before start of production (pre-SOP), he said. IT Home placed the remarks at the SAECCE automotive conference.

Why it matters: batteries limit how long a humanoid can work between charges, and XPeng is one of the few carmakers with a dated humanoid production target.

Key Facts

  • Battery: small-batch production, per VP Gu Jie (Yicai, Oct 28, 2026)
  • Robot: IRON still pre-SOP; mass production targeted by end-2026, store deployments from 2027
  • No energy density, capacity or runtime published
  • Open question: all-solid-state (XPeng site) vs semi-solid (CnEVPost, Sep 3) for production units

What did XPeng say about the battery?

Gu described a design for a robot’s limited internal space, with high energy density, measures to stop thermal runaway spreading, and resistance to impact and nail penetration, according to IT Home. XPeng published no energy density, capacity, runtime or cycle-life figures.

One question is open. XPeng’s IRON page advertises an all-solid-state battery; CnEVPost reported on September 3, citing Jipian Lab, that production robots would use semi-solid batteries instead. XPeng has not confirmed a change, and the October remarks do not settle it.

When will IRON ship?

XPeng commissioned IRON production lines in September and targets mass production by the end of 2026, with robots working in XPeng stores and commercial venues from 2027. Earlier coverage: IRON’s production line and XPeng Robotics’ $900M raise.
