Could New Battery Power Planes?
April 20, 2023
Chinese battery giant CATL (300750.SZ) on Wednesday unveiled a condensed matter battery that it said could supply enough energy to power electric passenger aircraft for civil aviation use.
The battery, a type of semi-solid state product with condensed electrolyte and new anode and separator materials, will have an energy density of 500 Watt hours per kilogramme (Wh/kg), according to Wu Kai, CATL’s Scientist in Chief, speaking to reporters at the Shanghai auto show.

Chinese electric vehicle (EV) maker Nio (9866.HK) is planning to power its ET7 cars with a semi-solid state battery with 360 Wh/kg energy density developed by Beijing Welion New Energy Technology.
CATL on Tuesday also announced its targets to achieve carbon neutrality with all its battery making plants by 2025, and across its battery value chain by 2035.
The commitments are important for CATL to meet increasing standards and regulations for the carbon footprint of its batteries in Europe and the United States as CATL expands into those markets.
Robin Zeng, CATL Chairman, said last year that it is essential to reduce carbons emissions in the batteries, which account for nearly 40% of all carbon emissions produced in the cycle of battery electric vehicles.
Zeng said his company had ramped up efforts since 2019 to analyse and seek solutions for carbon reduction in the battery-making industry, saying battery makers in China, Japan and South Korea have had a significant carbon footprint.
In the world of batteries, one brand has come to dominate nearly all others, CATL. The Chinese battery producer has quickly become the world’s largest battery producer and supplies some of the largest brands in the world, including some of the most prominent automakers. Now, the company is attempting to expand into the aviation sector as it has unveiled its most energy-dense battery ever, designed for use in electric planes.
CATL announced the new electric plane “Condensed Battery,” at the Shanghai auto show yesterday, and it has captured significant attention for its incredible energy density. According to CATL, the new battery will have an energy density of 500Wh/Kg, a number which is roughly double the Tesla 4680 at ~270Wh/Kg. Moreover, this project isn’t some concept that will never see the production line. CATL states the new battery will be entering mass production later this year.
According to the battery maker, this incredible energy density, which is desperately needed within the aviation industry, is achieved through a combination of innovations. CATL Chief Scientist Wu Kai noted that an all-new high-energy cathode and anode, improved isolation films, and a “micron-scale adaptive mesh structure” are the primary changes that allow for the electric plane battery’s incredible energy capacity.
While Kai didn’t extensively elaborate on how these innovations directly affect energy density, the company notes that most of the improvements, including the micron mesh structure, are put in place to regulate chemical reactions within the battery, which could otherwise go out of control at such a high energy load.
“Meeting customers’ requirements is the core driving force that drives technological innovation for CATL,” said Kai, noting that the business has been vastly growing its offerings across numerous price points.
This new battery addresses the most significant hurdle many electric plane manufacturers face, which has previously relegated the electric plane offerings to shorter domestic flights under 300 miles. With these new batteries, electric aircraft will likely be far from achieving the range of their gas-powered counterparts but significantly closer, potentially hitting 600-700 miles on a single charge.
The final big announcement from the Shanghai presentation was CATL’s involvement in a “civilian electric aircraft” project, though the company did not name any of its collaborators. CATL is expected to release more information on the project later this year, alongside the full production launch of the electric plane battery, but it was not immediately available for clarification to Teslarati.

Peter, years back you had a clip (which I can’t find) from one of the few Republican US Congressmen who understood climate change and the need to transition to new energy technology. Of course, being sensible, he was primaried, but before he left office he warned his colleagues that China was going to eat our lunch, technology-wise.
Our lunch is being et.

Of course price and energy density by volume hasn’t been mentioned.
