CATL doubles down on fast-charging batteries: what its latest Tech Day reveals for long-range EVs
CATL used its 2026 Tech Day to unveil several new battery products aimed at passenger vehicles, including packs for plug-in hybrids and extended-range models, plus updated battery-swap options. The announcements underline the company’s push to make long range and rapid charging compatible in mass-market designs.
Among the headline products is CATL’s third-generation Qilin battery, which the company says can reach 125 kWh and support vehicle ranges of at least 1 000 km under its test assumptions. The pack is based on nickel-cobalt-manganese chemistry, a route often chosen for higher energy density.
CATL also highlighted charging performance, claiming an equivalent 10C rate with peaks up to 15C for the new Qilin system under ideal conditions. In practice, real-world results can vary widely depending on charging power, thermal management, and ambient temperature.
Energy density claims and trade-offs
The company says the Qilin pack reaches about 600 Wh/L volumetric energy density and around 280 Wh/kg gravimetric density. CATL also stated the pack mass is roughly 625 kg, positioning it as lighter than some comparable lithium iron phosphate solutions at similar usable capacity.
Higher energy density can help automakers reduce pack volume, freeing cabin or cargo space and potentially improving efficiency. However, it can also increase engineering demands around cooling, crash protection, and long-term degradation control.
CATL additionally presented a Qilin Condensed battery concept with claimed densities up to 350 Wh/kg and 760 Wh/L. The company suggested this could enable up to 1 500 km range for large sedans in specific configurations and test cycles.
Shenxing charging and hybrid focus
For customers most focused on charging time, CATL introduced its third-generation Shenxing Superfast Charging battery. CATL says it can charge from 10% to 80% in 3 minutes and 44 seconds in internal testing, with performance claims extending to cold conditions down to −30°C.
CATL also cited durability figures, saying that after 1 000 full cycles the Shenxing pack retains more than 90% capacity based on its own tests. Independent verification, cell-to-pack integration choices, and charging behavior over time will all affect outcomes in production vehicles.
On the hybrid side, CATL announced a second-generation Freevoy Super Hybrid battery designed for PHEV and EREV models, claiming up to 500 km of pure electric range using LFP chemistry. It also introduced an NCM version with a stated 600 km electric-only range, positioning both around the company’s fast-charging targets.
Battery swapping expands to more classes
Battery swapping remains part of CATL’s strategy, with the new #26 Choco-Swap battery aimed at broader vehicle coverage and an 800-volt architecture. CATL said the first #26 pack planned for market is 75 kWh, with larger versions in development.
The company also indicated that swap stations for passenger vehicles and heavy-duty trucks will incorporate Shenxing fast-charging piles as standard equipment. The move suggests CATL is trying to align swapping infrastructure with ultra-fast charging, rather than treating them as competing approaches.
