Chinese Firm CATL Unveils Lithium-Air EV Battery Aiming for 1,200-Mile Range

Chinese battery maker CATL is exploring a new type of battery that uses air to potentially give electric cars more than 1,200 miles of driving range. Wu Kai, the company’s chief scientist and an academician of the Chinese Academy of Engineering, named this technology as a main focus for future research at the 2026 Equipment Power Forum.

Standard electric car batteries are sealed boxes packed with heavy metals like nickel, cobalt, and manganese. A lithium-air battery works differently by using an open design that pairs a pure lithium negative side directly with oxygen pulled from the air. Because the battery breathes in gas while it runs, it cuts out a lot of dead weight from the battery pack.

This setup gives the technology a theoretical energy limit of 12,000 watt-hours per kilogram, which matches the energy packed into regular gasoline. Lab tests have already pushed past 1,200 watt-hours per kilogram, scoring more than four times the power of standard electric vehicle batteries used today. If companies figure out how to build these batteries on a large scale, everyday cars could travel more than 1,000 miles on a single charge.

Despite that high potential, lithium-air batteries are very tough to make rechargeable, long-lasting, and practical. When the battery is open to the air, it reacts poorly to moisture and carbon dioxide, which quickly ruins the cells, breaks down catalysts, and shortens the battery's lifespan. The chemical reactions can also clog the battery's porous parts with solid lithium peroxide, making it harder for oxygen to flow through and shrinking the amount of usable energy over time.

Researchers have recently tested ways to fix these physical roadblocks. A team from the Illinois Institute of Technology and Argonne National Laboratory showed a room-temperature chemical method that builds and breaks down lithium oxide instead. They also swapped out liquid fluids that catch fire for a solid material made of ceramic and plastic polymers mixed with lithium particles to stop leaks and keep the battery stable.

CATL is shifting its long-term engineering staff to work on these hurdles, aiming the technology at heavy trucks and systems that store energy for wind and solar power grids. The company is not saying the technology will change the market right away, treating it for now as a long-term research project.

Summary

CATL’s work on lithium-air technology points to a future where electric vehicles could drive over 1,200 miles on one charge. Even though current lab tests show great promise, major chemical and durability problems must be solved before these batteries can be sold to drivers.
