CATL unveils its latest battery tech

CATL, the leading battery manufacturer in the world, introduced a slew of new cutting-edge battery products during the 2026 Tech Day. The company introduced batteries designated for passenger vehicles, including PHEV and EREV, as well as battery swap solutions.

Let's start with the third-generation Qlin battery, which holds a 125 kWh capacity, enough to power the vehicle for at least 620 miles before needing a recharge. The battery is based on the nickel-cobalt-manganese chemistry, and the impressive capacity isn't even the highlight feature.

According to CATL, the battery charging rate is equivalent to 10C and peaks at 15C. That translates to 4-6 minutes of charging to full. Of course, those numbers are theoretical, and the charging power also depends on temperature, charging stations, etc.

The energy density is also mighty impressive. The volumetric energy density is 600 Wh/L, while the gravimetric density is said to be 280 Wh/kg. That makes the pack significantly smaller and lighter, tipping the scale at 1,378 lb, or 562 lb lighter than comparable LFP batteries.

This will allow engineers to design lighter cars with more cabin space. Additionally, the vehicles equipped with the said battery will have lower consumption, increased safety when maneuvering and also reduce the stress on certain components, extending their lifespan.

CATL also showcased a Qlin Condensed battery with 350 Wh/kg gravimetric density and 760 Wh/L volumetric density. With a battery this size, CATL predicts that big sedans will be able to reach 932 miles ranges, while full-sized SUVs will be able to reach 620 miles on a single charge.

The third-generation Shenxing Superfast Charging battery aims to solve the charging time issues. Just like the Qlin battery, its theoretical charging power is capable of equivalent 10C with a peak of 15C.

According to CATL's tests, the pack can charge from 10% to 35% in just one minute, while a 10% to 80% charge takes only 3 minutes and 44 seconds. Going from 10% to 98% takes only 6 minutes and 27 seconds. Even in extremely cold temperatures of −30°C, the battery can perform just as well, charging from 20% to 98% in 9 minutes.

After 1,000 complete charging cycles, the battery retains more than 90% of its capacity, again according to CATL's internal tests.

The Freevoy Super Hybrid battery, on the other hand, moves to the second generation. It's designed for PHEV and EREV models and offers 311 miles of pure electric range and supports an equivalent 10C charging speed. CATL says this battery will enable a "once-a-week charging" experience for EREV models.

The battery is based on the LFP chemistry and has 230 Wh/kg energy density, but an NCM version was also introduced. It supports the same equivalent 10C charging speed and provides 373 miles of pure electric range.

Last but not least, CATL introduced #26 Choco-Swap battery, succeeding the #20 and #22 versions. The newer battery now covers all vehicle classes with an 800-volt architecture. The first #26 Choco-Swap battery to hit the market will be 75 kWh, but larger batteries are also in the works.

Both Choco-Swap and Qiji swap stations for heavy-duty trucks will come standard with the Shenxing superfast charging piles.
