High-density lithium battery packs for humanoids

The humanoid battery pack market is still tiny in absolute revenue but is one of the fastest-growing component categories, and it is being contested by the incumbent EV cell majors rather than by robotics specialists. A new market sizing published 19 August 2026 is the most recent datapoint retrieved.

Key findings

MarketsandMarkets (release dated 19 August 2026) estimates the global humanoid robot battery market at about US$14.0 million in 2025, projected to reach roughly US$622 million by 2032, a CAGR of about 72%.
That study names the leading suppliers as LG Energy Solution, Samsung SDI, SK On, CATL, BYD, Panasonic Energy, EVE Energy, Sunwoda Electronic, Farasis Energy, Gotion High-tech and TDK.
A separate market study (published within the last month) puts the humanoid robot battery system market at a 68.3% CAGR to 2032 and profiles an overlapping supplier set including Saft, Lishen, Grepow and Jiangsu Blue Lithium.
CATL commissioned what it describes as the world's first humanoid-robot-enabled battery pack production line at its Luoyang, Henan base (announced December 2025), using a robot named 'Xiaomo' to replace human labor in several pack processes - relevant as a capacity/manufacturing signal rather than a cell spec.
Supplier-side selection criteria cited for humanoid packs span roughly 260-500 Wh/kg energy density and 3C-50C discharge, with solid-state commercialization targeted for 2026-2028 (vendor-published, not independently verified).
