Global battery leader CATL is accelerating its research into lithium-air battery technology as a potential game changer for future energy storage solutions. Speaking at the 2026 Powering The Nation forum, Chief Scientist Wu Kai highlighted the technology’s remarkable theoretical energy density of 12,000 Wh/kg, approaching the energy content of gasoline. By using lithium metal as the anode and oxygen from the surrounding air as the cathode reactant, these “breathing batteries” promise to be significantly lighter and more energy-dense than conventional lithium-ion cells. If successfully commercialized, lithium-air batteries could enable electric vehicles to travel more than 1,000 miles (1,600 km) on a single charge.
Although lithium-air technology has been studied since the 1970s, commercialization has long been hindered by challenges such as moisture sensitivity, carbon dioxide interference, and limited cycle life. Recent breakthroughs, however, suggest these barriers are gradually being overcome. In 2025, researchers from Argonne National Laboratory and the Illinois Institute of Technology developed a prototype capable of delivering 1,200 Wh/kg energy density and a lifespan of 1,000 charge cycles at room temperature. Unlike earlier designs that relied on lithium peroxide formation, the new approach uses a four-electron chemical reaction that enables the formation and decomposition of lithium oxide, significantly improving efficiency.
To enhance safety and durability, researchers replaced flammable liquid electrolytes with a solid-state composite matrix. This ceramic-polyethylene oxide polymer, reinforced with lithium-rich nanoparticles, stabilizes the battery cells while eliminating leakage risks during high-energy operation, making the technology safer and more reliable.
While CATL continues to focus on mature battery chemistries such as NMC, LFP, and sodium-ion batteries to meet current market demand, the company views solid-state batteries as a medium-term objective. Lithium-air technology, meanwhile, remains at the heart of CATL’s long-term research and development strategy, targeting commercialization beyond 2030.
