CATL is moving toward mass production of a battery with an energy density of 350 Wh/kg designed specifically for electric aircraft.
When you are in the air, there is zero room for error. The company recently passed a rigorous safety test by intentionally triggering two adjacent battery cells. This checks for "thermal runaway"—a situation where one cell overheats and sets off a chain reaction of fires. Because the heat stayed contained, the system meets the tough safety standards required for passenger flying cars, or eVTOLs.
🔹 This energy density is roughly 50% higher than what you find in standard electric car batteries.
🔹 It is the world’s first aviation battery system using prismatic cells to pass this thermal runaway test.
🔹 All testing and cell production were verified by officials from the Civil Aviation Administration of China.
In an electric vehicle on the ground, extra battery weight is annoying, but in the air, it is a dealbreaker. By packing more energy into the same space compared to standard automotive packs, these batteries allow aircraft to travel further without becoming too heavy to lift off.
Safety in the sky is finally catching up to power.
