CATL Unveils Game-Changing Battery Technology With Six-Minute Full Charge Capability

Chinese battery manufacturer CATL has unveiled a suite of cutting-edge battery innovations designed to reshape the electric vehicle landscape, with the standout achievement being a superfast charging battery capable of reaching 98 percent capacity in just six minutes.

The company revealed its latest technological breakthroughs during its Super Technology Day event on April 21, 2026, marking an intensifying competition with fellow industry giant BYD. The announcement included the third-generation Shenxing Superfast Charging Battery, the third-generation Qilin Battery, the Qilin Condensed Battery, a second-generation Freevoy Super Hybrid Battery, the latest Naxtra Sodium-ion Battery, and a fully integrated supercharging and battery-swapping infrastructure solution. Company officials emphasized that "these innovations are designed to address diverse mobility needs across different usage scenarios."

Breaking Speed Records

CATL's latest Shenxing Superfast battery outpaces rival BYD's recent fast-charging achievement by three minutes. While BYD's new LFP Blade battery requires nine minutes to charge from 10 to 97 percent—or just 12 minutes in extreme cold at -30°C—CATL's third-generation offering accomplishes the same task from 10 to 98 percent in six minutes and 27 seconds.

"We always deliver what we promise," declared Gao Huan, CATL's chief technology officer, during the Tuesday announcement. The battery achieves true 10C charging rates with peak performance at 15C, enabling a charge from 10 to 35 percent in merely one minute and reaching 80 percent in three minutes and 44 seconds. Even under extreme conditions of -30°C, the battery charges from 20 to 98 percent in approximately nine minutes.

The nickel-cobalt-manganese composition provides 1,000 kilometers (621 miles) of driving range. After 1,000 complete charge cycles, the battery maintains above 90 percent capacity retention, achieving what the company describes as an optimal balance between extreme fast charging and extended service life.

Premium Range With Lightweight Design

The third-generation Qilin battery targets the premium electric vehicle segment, addressing the traditional tradeoff between range and weight. Achieving a cell energy density of 280 Wh/kg, this battery enables 1,000-kilometer range capability while supporting 10C super-fast charging. The entire battery pack weighs only 625 kilograms—255 kilograms lighter than equivalent lithium iron phosphate systems—while saving 112 liters of space.

The weight reduction delivers cascading benefits across vehicle performance and efficiency:

• Energy consumption decreases by more than 6 percent, saving approximately 0.78 kWh per 100 kilometers. Across a fleet of one million vehicles traveling 20,000 kilometers annually, this represents 156 million kWh in electricity savings and a reduction of 78,500 tons of CO₂ emissions
• Acceleration improves by 0.6 seconds in the 0-100 km/h sprint, while moose test speeds increase and body roll angles decrease, enhancing obstacle avoidance capability and reducing braking distance
• Component durability extends by 40 percent for chassis elements and over 30 percent for tires, allowing replacement intervals to increase by at least 10,000 kilometers
• Reclaimed space boosts cabin headroom by at least 18 millimeters

The battery employs "thermal-electrical separation" technology, where each cell incorporates an independent sealed exhaust channel to isolate thermal events and prevent propagation.

Record-Breaking Energy Density Achievement

The Qilin Condensed Battery represents a pioneering application of aviation-grade technology to passenger vehicles, achieving unprecedented energy density figures of 350 Wh/kg and 760 Wh/L. These accomplishments enable 1,500-kilometer range possibilities for sedans and exceed 1,000 kilometers for large sport utility vehicles, with the complete battery pack weighing less than 650 kilograms.

The innovation combines a high-nickel cathode with a low-expansion silicon-carbon anode, increasing energy density by 50 Wh/kg. An aviation-grade titanium alloy case reduces thickness by 60 percent and weight by 30 percent while tripling unit strength and delivering an additional 20 Wh/kg in energy density gains. This development builds upon CATL's electric aviation initiatives, where 500 Wh/kg systems have completed successful maiden flight validation on four-ton aircraft, with further validation underway on aircraft exceeding eight tons.

A condensed electrolyte system eliminates traditional leakage and combustion risks, achieving "no liquid to leak, no liquid to ignite." The battery also incorporates a composite current collector functioning as a rapid self-fusing protection device during extreme internal short-circuit scenarios.

Hybrid Solution and Sodium-Ion Progress

The second-generation Freevoy Super Hybrid Battery extends battery-only electric range to 600 kilometers and standardizes 10C super-fast charging. It pioneered a gradient-uniform mixing technology integrating lithium iron phosphate and nickel-cobalt-manganese materials at the powder particle level, delivering 230 Wh/kg energy density and range increases exceeding 15 percent without additional pack weight. The system provides 1.5 megawatts of instantaneous power at full charge and maintains 1.2 megawatts at 20 percent state of charge.

The Naxtra Sodium-ion Battery marks CATL's transition from laboratory development to large-scale manufacturing, with the company successfully addressing four critical production bottlenecks including extreme water control, gas generation in hard carbon, aluminium foil adhesion, and self-forming anode systems. Mass production deployment is scheduled for the end of 2026.

Infrastructure Network Expansion

CATL introduced a unified integrated supercharging and battery-swapping network built on three complementary pillars: home charging, public charging, and battery swapping. All passenger vehicle "Choco-Swap" and heavy truck "QIJI" swapping stations will feature Shenxing supercharging systems, enabling true charge and swap synergy.

The integrated charge and swap stations feature shared compact substations and charging modules, reducing energy conversion steps and lowering overall power loss by more than 13 percent compared with conventional storage-equipped charging stations. Service capacity reaches three times per parking space, while fixed supercharging investment costs decrease by 20 percent.

CATL intends to construct 4,000 integrated charge and swap stations by the end of 2026, covering nearly 190 cities and a nationwide highway network spanning 12 vertical and 11 horizontal corridors. The existing Choco-Swap network has already established 1,470 stations across 99 cities, with expansion continuing to accelerate.

Strategic Vision

Company chairman and chief executive officer Robin Zeng emphasized at the conference that industrial innovation must be driven by rigorous scientific principles. "For Chinese technology to go global, it relies not just on speed and scale, but on the quality of innovation, the ability to validate, and the credibility of the brand," Zeng stated.

The company intends to continue investments in advanced research, large-scale manufacturing, and ecosystem collaboration to advance from single-point innovation toward comprehensive full-scenario energy solutions.
