CATL showcases an expansive battery portfolio at its Super Technology Day in Beijing

CATL unveiled one of its most ambitious technology lineups to date during its Super Technology Day event in Beijing, introducing six next‑generation battery systems and a fully integrated supercharging and battery‑swapping ecosystem designed to support the future of electrified mobility. The announcements span third‑generation fast‑charging technologies, aviation‑grade condensed batteries, hybrid‑focused chemistries and large‑scale sodium‑ion industrialization, underscoring CATL’s strategy to advance multiple battery pathways in parallel.

During the event, CATL Chief Scientist Dr. Wu Kai outlined the scientific rationale behind the company’s multi‑chemistry roadmap. He emphasized that LFP is approaching its theoretical energy density ceiling, making it best suited for extreme fast‑charging applications, while NCM remains the leading chemistry for high‑energy‑density systems. Sodium‑ion, he noted, offers strong potential for extreme‑temperature performance and grid‑scale storage. “Whether from the perspective of differentiated consumer needs, or from the viewpoints of energy security and social development, the lithium‑ion battery industry must pursue coordinated development across multiple chemical systems,” he said. Chairman and CEO Robin Zeng added that global leadership requires not only speed and scale but also scientific rigor, validation and brand credibility.

The third‑generation Shenxing Superfast Charging Battery was one of the headline announcements. CATL has engineered the system to minimize heat generation and improve thermal propagation control, enabling extreme charging speeds without compromising longevity. After 1,000 full cycles, capacity retention remains above 90%. The battery supports an equivalent 10C and peak 15C charging rate, reaching 35% state of charge in one minute and 80% in under four minutes. Even at –30°C, charging from 20% to 98% takes about nine minutes. Combined with CATL’s integrated supercharging and battery‑swapping network, the system is designed to deliver consistent fast‑charging performance in all climates.

CATL also introduced the third‑generation Qilin Battery, engineered for premium long‑range EVs. With a cell energy density of 280 Wh/kg, it enables up to 1,000 km of driving range while supporting 10C fast charging. The pack delivers 3 MW peak power – double that of the previous Qilin track battery – and weighs just 625 kg, reducing mass by 255 kg compared with equivalent LFP systems. The lightweighting benefits translate into lower energy consumption, improved acceleration, shorter braking distances, enhanced handling stability and extended component durability. Safety is reinforced through a “thermal‑electrical separation” design that isolates thermal events within individual cells.

The Qilin Condensed Battery pushes energy density even further, applying aviation‑grade technology to passenger vehicles for the first time. With 350 Wh/kg at the cell level and 760 Wh/L volumetric density, it enables up to 1,500 km of range for sedans. A titanium‑alloy case reduces weight by 30% while tripling structural strength, and a condensed electrolyte system eliminates leakage and combustion risks. The technology builds on CATL’s electric aviation program, where 500 Wh/kg systems have already completed maiden flight validation.

For hybrid vehicles, CATL introduced the second‑generation Freevoy Super Hybrid Battery, which integrates LFP and NCM materials at the particle level to achieve 230 Wh/kg energy density and up to 600 km of pure electric range. The system standardizes 10C fast charging and delivers up to 1.5 MW of instantaneous power, maintaining high output even at low state of charge. Safety enhancements include reinforced underbody protection and deep‑water immersion resistance.

CATL also announced GWh‑scale industrialization of its Naxtra Sodium‑ion Battery, marking a transition from laboratory innovation to mass production. The company has resolved key engineering challenges – including water control, gas generation, adhesion and self‑forming anode systems – and expects full‑scale production by the end of 2026.

Beyond individual products, CATL introduced a unified supercharging and battery‑swapping architecture that integrates home charging, public charging and swapping into a single ecosystem. All passenger‑vehicle Choco‑Swap and heavy‑truck QIJI stations will incorporate Shenxing supercharging systems, enabling each site to function as both a high‑power charging hub and a swapping node. The integrated design reduces energy conversion losses, increases equipment utilization and lowers infrastructure investment costs. CATL plans to deploy 4,000 integrated charge–swap stations by the end of 2026, covering nearly 190 cities and major highway corridors. The company aims to co‑develop a nationwide “charge–swap sharing network” with automakers including Changan, Chery, GAC, Seres, SAIC‑GM‑Wuling and BAIC, targeting more than 100,000 shared facilities by 2028.

CHANGAN Automobile, together with battery giant CATL, has unveiled the world’s first mass‑production passenger vehicle powered by sodium‑ion batteries, marking a pivotal moment in the global transition to next‑generation energy storage. The announcement was made during the “CHANGAN SDA Intelligence Milestone Release & Sodium‑Ion Battery Global Strategy Launch,” where the company confirmed that the new vehicle will…
