XPeng begins small-batch production of solid-state batteries for IRON robot

The milestone matters less for XPeng's automotive ambitions than for its robotics timeline: solid-state cells moving from lab to small-batch lines signals the power-density and safety trade-offs are being tested in hardware, not just prototypes. The pre-SOP stage is where manufacturing yield and cost per cell typically get exposed, and XPeng's silence on volume-production and delivery dates leaves that risk unresolved. The open question is whether small-batch output scales without a stated timeline, and whether the battery work becomes a supplier story beyond the IRON robot itself.
