Asia Tech Wire (Nov 15) -- China's EHang Holdings Limited (Nasdaq: EH) announced Thursday that it has made the debut of a solid-state battery on an electric vertical takeoff and landing (eVTOL) aircraft.

EHang said it has made a major technological breakthrough in the use of high-energy solid-state batteries for the EH216-S unmanned aerial vehicle, and that the eVTOL featuring the solid-state battery successfully flew uninterruptedly for nearly 50 minutes, with a 60% to 90% increase in endurance.

In the industry's view, due to eVTOL's high requirements for battery energy density, power, and safety, solid-state batteries are a more ideal choice, but not the only choice.

A veteran eVTO industry source introduced that different batteries will directly affect the flight distance and load capacity of low-flying objects, thus corresponding to their use scenarios.

Zhao Wang, COO of EHang, said that the company is also working with other partners to try to develop batteries for different application scenarios, such as ultra-fast charging and discharging battery solutions for high-frequency short-haul flights, etc.

Wang said EHang will also customize its battery service solutions for users based on actual needs in the future.

The company plans to realize the certification and mass production of the solid-state battery in EH216-S by the end of 2025.
