CATL Aviation Battery Passes Thermal Runaway Test for Adjacent Cells
Recently, the aviation power battery system developed by CATL for passenger eVTOLs successfully passed the verification test of no thermal runaway propagation for adjacent cells. It is the world's first aviation power battery system using prismatic cells with an energy density of 350 Wh/kg to pass such a test, underscoring a new benchmark in safety performance.
During the test, adjacent cells at various locations, including the middle and corners of the pack, were simultaneously triggered, with no thermal propagation occurring. This technological breakthrough and verification will provide safer power assurance for the development of the low-altitude economy, serving as another testament to CATL's continuous exploration of the safety boundaries of power batteries.
The entire production, inspection, and testing of the cells and battery system was completed under the witness of designated representatives from the Civil Aviation Administration of China (CAAC). This lays a solid foundation for eVTOLs to meet civil aviation safety standards.
The aviation battery system is now ready for mass production. It will be first used on AutoFlight's passenger eVTOLs. From new energy vehicles to passenger aviation, CATL will join hands with partners, universities, and research institutions to continuously tackle technical challenges, strengthening the safety foundation for aircraft manufacturers and users alike.
