CATL battery innovations took center stage at the company’s Super Technology Day in Beijing on May 1, 2026. CATL introduced six major technologies that target fast charging, longer range, hybrid performance, sodium-ion adoption, and energy replenishment infrastructure. Together, these updates show how CATL plans to support different vehicle types and driving needs with a multi-chemistry strategy.
During the event, CATL leaders explained why battery chemistry diversity matters. Dr. Wu Kai, Chief Scientist of CATL, said LFP batteries now suit ultra-fast charging roadmaps especially well. He also noted that NCM remains important for high energy density. In addition, he highlighted sodium-ion batteries as a strong option for extreme temperatures and energy storage. Robin Zeng, Chairman and CEO of CATL, added that lasting global success depends on innovation quality, verification, and brand credibility.
CATL battery innovations: Third-Generation Shenxing Superfast Charging Battery
The third-generation Shenxing Superfast Charging Battery focuses on charging speed and long service life. CATL improved this battery through three steps. First, it reduced heat generation during operation. Second, it strengthened heat dissipation and thermal control. Third, it increased control precision.
As a result, the battery keeps more than 90% capacity after 1,000 full cycles. It also delivers an equivalent 10C charging capability and a peak 15C charging rate. CATL says the battery can charge from 10% to 35% in 1 minute. It can go from 10% to 80% in 3 minutes and 44 seconds. Moreover, it reaches 98% from 10% in 6 minutes and 27 seconds. Even at -30°C, charging from 20% to 98% takes about 9 minutes.
CATL also paired battery self-heating with its integrated charging and swapping network. Therefore, drivers can access faster charging in cold weather with more flexibility.
CATL battery innovations: Third-Generation Qilin Battery
The third-generation Qilin Battery targets premium long-range Electric Vehicles. It reaches a cell energy density of 280 Wh/kg and supports a driving range of up to 1,000 km. At the same time, it supports 10C superfast charging.
This battery delivers 3 MW peak power. That figure doubles the output of CATL’s second-generation Qilin track battery, which delivered 1,330 kW. The full battery pack weighs 625 kg. Compared with similar LFP systems, CATL cut 255 kg in weight and saved 112 litres of space.
Those changes improve efficiency and vehicle dynamics. For example, energy use per 100 km drops by more than 6%. That equals a savings of about 0.78 kWh per 100 km. CATL also reports faster acceleration, shorter braking distance, better handling, and lower body roll. In addition, the saved space can raise cabin headroom by at least 18 mm.
For safety, CATL uses thermal-electrical separation. Each cell has an independent sealed exhaust channel. As a result, the design helps isolate thermal events and limit propagation.
CATL battery innovations: Qilin Condensed Battery
The Qilin Condensed Battery brings aviation-grade technology into passenger vehicles. It achieves 350 Wh/kg cell energy density and 760 Wh/L volumetric energy density. CATL says this supports up to 1,500 km range for sedans and more than 1,000 km for large SUVs. Meanwhile, pack weight stays within 650 kg.
CATL combined a high-nickel cathode with a low-expansion silicon-carbon anode. This added 50 Wh/kg in energy density. The company also introduced a titanium alloy case. That cut thickness by 60% and weight by 30%, while tripling unit strength. In turn, this structure adds another 20 Wh/kg.
CATL says the condensed system removes liquid electrolyte leakage and ignition concerns. It also adds a composite current collector that works as a fast self-fusing fuse during extreme internal short circuits.
CATL battery innovations: Second-Generation Freevoy Super Hybrid Battery
The second-generation Freevoy Super Hybrid Battery pushes hybrids deeper into the pure electric era. It offers up to 600 km of all-electric range and standard 10C superfast charging. CATL uses a hybrid material approach that combines LFP and NCM at the particle level.
The battery reaches 230 Wh/kg energy density. CATL says this increases range by more than 15% without adding pack weight versus single LFP systems. The LFP version provides up to 500 km of pure electric range. The NCM version extends pure electric range beyond 600 km and total vehicle range past 2,000 km.
Performance also stands out. The system provides 1.5 MW of instantaneous power at full charge and 1.2 MW at 20% state of charge. CATL also designed strong safety protection, including a bottom coating that withstands 1,500 joules of impact and waterproof sealing for more than 200 hours in 2 metres of water.
CATL battery innovations: Naxtra Sodium-ion Battery
The Naxtra Sodium-ion Battery marks CATL’s move toward large-scale sodium-ion production. CATL says it has achieved GWh-scale industrialisation and plans full-scale mass production by the end of 2026. This battery supports CATL’s broader multi-chemistry roadmap and expands options for future mobility and energy storage applications.
CATL battery innovations: Integrated supercharging and battery-swapping network
CATL also launched a fully integrated supercharging and battery-swapping solution. The system connects home charging, public charging, and battery swapping into one replenishment architecture. CATL will equip all passenger vehicle Choco-Swap stations and QIJI truck swapping stations with Shenxing supercharging systems.
The company says these stations cut overall power loss by more than 13 percentage points compared with conventional storage-equipped charging stations. In emergency use, station batteries can discharge directly to charging piles. This lifts equipment utilization above 85%. In addition, each parking space can deliver three times the service capacity of conventional setups.
CATL also introduced the Choco-Swap #26 battery with 800V architecture and a 75 kWh version. The system will support B- to C-segment 800V vehicles, with more capacity versions coming later. By the end of 2026, CATL plans to build 4,000 integrated charge-swap stations across nearly 190 cities and major highway corridors.
CATL battery innovations point to a broader mobility strategy
CATL battery innovations show a clear plan to serve full mobility scenarios. The company now offers products across LFP, NCM, hybrid, condensed, and sodium-ion technologies. Moreover, it pairs those batteries with a growing charging and swapping network. As a result, CATL strengthens its role in the shift toward faster, longer-range, and more flexible new energy mobility.
