XPeng Starts Making Solid-State Batteries for Its Humanoid Robot

Keypoints:

• XPeng began small-batch production of solid-state batteries
• The first customer is its own humanoid robot, called Iron
• Robot mass production is targeted for the end of 2026
• Formal launch and deliveries are planned for 2027
• The cells include protection against thermal runaway spreading

XPeng has started small-batch production of solid-state batteries, and the first customer is its own humanoid robot, called Iron. Notebookcheck reported the news on November 2. The company wants Iron in mass production by the end of 2026, with a formal launch and deliveries in China and overseas planned for 2027.

Why a robot first? A humanoid body has very little room inside, so the battery has to pack a lot of energy into a small space, and it has to be safe because it sits close to people. XPeng says it redefined its battery standards for robots, including protection that stops a thermal runaway from spreading from one cell to the next. The battery is described as high energy density, though the exact chemistry hasn't been shared.

This fits a bigger industry view. Notebookcheck notes that battery suppliers CATL and Panasonic both believe solid-state cells will make commercial sense first for drones and robots, and only later for electric cars. 

CATL now plans big solid-state EV packs for mass production in 2030 and beyond. Robots and drones need much smaller packs, so manufacturers can start building them in low volume while the harder work of making car sized packs cheap continues.

Early jobs for Iron will be in retail, such as helping shoppers and introducing products. That's a gentle starting point, but it also means the robot will be around the public, which is why safety was a headline feature of the battery design.

The rest of the week's battery news shows how crowded this space is. A weekly industry update also noted Svolt starting mass production of a 100 kilowatt hour semi-solid pack, Group14 putting 150 million euros into a 10 gigawatt hour plant in Spain, and a 1 gigawatt hour US storage deal for Samsung SDI.

What to watch next is whether XPeng shares the chemistry, cost and range before the 2027 launch. Until then, Iron is a useful test of whether solid-state batteries can leave the lab and work inside a real product.
