CALB to Deliver Solid-State Batteries for eVTOL and Robotics by Q4 2026

CALB Secures Exclusive Battery Supply for Major eVTOL Manufacturers

CALB has entered into exclusive power battery supply agreements with leading Chinese eVTOL manufacturers, including XPeng Heite and GAC GOVE, marking its official entry into the aircraft supply chain. The company has also completed development of its 'Unbounded' all-solid-state battery system, achieving an energy density of 450 Wh/kg.

Mass production and delivery of one thousand units are scheduled for the fourth quarter of 2026, primarily targeting the robotics and aircraft sectors. A solid-state battery for passenger vehicles, with an energy density of approximately 430 Wh/kg, is planned for vehicle installation in 2027.

What This Means for B2B Buyers

This development demonstrates the near-term commercial viability of high-energy-density solid-state batteries for demanding applications like electric vertical takeoff and landing (eVTOL) aircraft. For B2B clients, CALB's progress signals a major shift in the supply chain towards advanced battery technologies for the low-altitude economy.

• CALB is concurrently expanding global production capacity with multi-billion dollar projects in China and Portugal, ensuring supply chain readiness.
• In 2025, the company's energy storage system revenue reached 14.1 billion CNY, up 71.9% year-over-year, ranking fourth globally in shipments.
• Analysts from Bank of America Securities and Shenwan Hongyuan have issued positive ratings, citing overseas expansion and product structure optimization.

According to the original report from Economic Observer Online, industry challenges remain, including overcapacity and price competition, but CALB's technological lead positions it strongly in the evolving market.
