Chinese battery giant Contemporary Amperex Technology Company Limited (CATL) is making significant strides in the aviation industry. With its latest innovation, CATL is set to revolutionize electric aircraft by promising an 8-ton electric plane with an impressive range of 2,000 to 3,000 kilometres (1,240 to 1,865 miles) by 2028, according to a report from China Daily . This development could mark a significant leap in clean aviation technology, offering new possibilities for the future of air travel.
CATL, the world leader in manufacturing batteries for electric vehicles, currently holds 37% of the market share. Major car manufacturers, including Ford and Tesla, use CATL batteries. In April 2023, CATL announced its groundbreaking “condensed battery,” which boasts an energy density of 500 Wh/kg.
This is over twice the energy density of most existing batteries on the market. A typical lead-acid car battery offers around 50 Wh/kg, while lithium-ion batteries, such as those in the Tesla Model 3, can reach approximately 265 Wh/kg.
This high-density battery is designed with aviation in mind, prioritizing safety and weight. Its application in aviation-grade batteries aims to extend the range of electric aircraft significantly.
Just three months after the announcement of the condensed battery, CATL established an aviation division in partnership with the state-owned Commercial Aircraft Corporation of China (COMAC). This collaboration has already seen remarkable progress. On Tuesday, CATL announced the successful test flight of a 4-ton electric aircraft powered by its condensed battery.
While details about the aircraft’s battery bank, engine configuration, and flight data remain closely guarded, the achievement is a significant milestone. CATL aims to have a commercial electric aircraft with a range of 2,000 to 3,000 kilometres ready by 2027 or 2028.

An 8-ton aircraft, while smaller than a Boeing 737 or an Airbus A320, is comparable to a Learjet 70/75, which can carry nine passengers. This indicates CATL’s initial target market for its electric aircraft.
The range figures promised by CATL far exceed those of any current clean passenger aircraft. Even futuristic battery-electric airliner concepts, such as the Elysian E9X, promise no more than 1,000 kilometres (621 miles). Current technology, including liquid hydrogen fuel, does not approach the range CATL is aiming for. If CATL delivers on its claims, it would represent a significant advancement in aviation technology.
Chinese aviation authorities have shown a willingness to embrace futuristic electric air transport. They have fully certified eHang’s eVTOL air taxi operations years ahead of the US and European regulators, demonstrating a commitment to advancing electric aviation.
Despite the promising developments, challenges remain. High energy density batteries, such as the 500 Wh/kg condensed battery, pose a risk of thermal runaway, which can lead to catastrophic outcomes if not properly managed. Ensuring safety is paramount as CATL works to bring its electric aircraft to market.
The latest update on CATL’s electric aircraft project was revealed at the 15th World Economic Forum Annual Meeting of the New Champions, also known as the Summer Davos Forum, in Dalian, China. CATL Chairman Robin Zeng discussed the company’s progress and future plans, highlighting the potential of the new batteries to support a range of 2,000 to 3,000 kilometres by 2027-2028.
Zeng also mentioned that CATL is working on next-generation sodium-ion batteries, which are expected to offer lower costs and improved performance. These new batteries could be launched as early as next year.
CATL’s ambitious plans for electric aircraft could transform the aviation industry, offering a cleaner and more sustainable alternative to traditional jet fuel-powered planes. The successful test flight of the 4-ton aircraft and the development of the 8-ton aircraft mark significant milestones in this journey.
