CATL Unveils Third-Generation Shenxing LFP Battery That Charges to 98 Percent in 6 Minutes 27 Seconds, Leapfrogging BYD's Blade 2.0
At its April 21 Super Technology Day in Beijing, CATL introduced a new ultra-fast charging LFP cell that outpaces BYD's recently unveiled Blade Battery 2.0 and reshapes the fast-charging race.
Overview
Contemporary Amperex Technology (CATL), the world’s largest electric-vehicle battery maker, used its April 21 Super Technology Day in Beijing to unveil a third-generation Shenxing lithium iron phosphate (LFP) cell capable of charging from 10 to 98 percent state of charge in 6 minutes and 27 seconds, according to Electrek. The announcement leapfrogs the fast-charging benchmark that rival BYD set only six weeks earlier with its second-generation Blade Battery and marks the latest escalation in a Chinese battery race that Western manufacturers have struggled to keep pace with.
The new cell was one of six product announcements CATL packaged together at the Beijing event, which the company branded as a showcase of “multi-chemistry systems to redefine new energy mobility experience,” according to a CATL press release distributed via PR Newswire.
What We Know
The third-generation Shenxing battery’s headline charging figures are a sharp step up from the previous generation and from competing products on the market.
- 10 to 35 percent in 1 minute
- 10 to 80 percent in 3 minutes and 44 seconds
- 10 to 98 percent in 6 minutes and 27 seconds
Those numbers come from Electrek’s coverage of the launch, which reports that the cell operates at an equivalent 10C charging rate with a 15C peak and carries an internal resistance of 0.25 milliohms — roughly 50 percent below the industry average, according to CATL’s own figures cited in the piece.
Cold-weather performance, historically the weakest link for LFP chemistry, received particular attention. At minus 30 degrees Celsius, the pack can charge from 20 to 98 percent in about nine minutes, and the cell uses a self-heating pulse technology that allows it to warm itself via a standard DC charger rather than relying on bespoke charging equipment, InsideEVs reported. CATL says the battery retains more than 90 percent of its original capacity after 1,000 ultra-fast charging cycles, also per InsideEVs.
The comparison with BYD is the subtext of the entire announcement. BYD’s second-generation Blade Battery, which The Machine Herald covered in March, charges from 10 to 97 percent in nine minutes and from 10 to 70 percent in five minutes, with a minus-30-degree Celsius charge time of 12 minutes to 97 percent, Electrek noted. On every one of those metrics, CATL’s new cell is faster.
CATL chief scientist Wu Kai framed the launch in terms of chemistry’s broader limits, saying that “LFP is nearing its theoretical energy density limit” and calling for “coordinated development across multiple chemical systems,” according to the company’s PR Newswire release. CATL chairman and chief executive Robin Zeng struck a more strategic note in the same release, saying that “industrial innovation must be driven by a rigorous scientific spirit” and that Chinese technology’s global expansion “relies not just on speed and scale, but on the quality of innovation, the ability to validate, and the credibility of the brand,” per the PR Newswire release.
Beyond the Shenxing cell, CATL used the Tech Day to introduce a third-generation Qilin battery, a Qilin Condensed Matter battery, the second-generation Freevoy hybrid pack, the Naxtra sodium-ion battery, and an integrated supercharging and battery-swapping network architecture, also detailed in the PR Newswire release. The charging infrastructure announcement is tied directly to the new Shenxing cell.
The competitive context matters because CATL’s market lead is significant but contested. CATL held 39.2 percent of the global EV battery market in 2025, with BYD second at 16.4 percent, Electrek reported, citing SNE Research data. BYD’s March push on charging speed and its own vertically integrated charging network had put pressure on the incumbent; the Shenxing announcement is the direct answer.
What We Don’t Know
CATL has not publicly disclosed the nominal voltage or maximum power input of the third-generation Shenxing cell, InsideEVs reported, which makes it difficult to independently verify how the advertised 10C and 15C charge rates translate into real-world kilowatt figures at the pile. The company has also not named the first production vehicles that will ship with the new cell, nor has it released pricing information or announced specific mass-production timelines for the Shenxing 3.0 pack itself in the materials published for the launch. The surrounding battery-swap infrastructure target — 4,000 integrated charge-and-swap stations across nearly 190 cities by the end of 2026 — was disclosed in CATL’s PR Newswire release, but the document does not break out Shenxing cell shipments separately.
Independent validation of the charging and cycle-life claims will also take time. The figures cited at the Tech Day are CATL’s own, and the company has not published peer-reviewed test data or third-party certifications for the third-generation Shenxing to date. Historically, fast-charging benchmarks from Chinese manufacturers have held up in production vehicles, but the gap between laboratory conditions and the electrical grid that any given driver plugs into can be substantial, particularly outside China.
Finally, the export question remains open. CATL is currently facing U.S. regulatory restrictions on its American operations, and its ability to deploy the new Shenxing cell in Western markets — as opposed to in Chinese-built vehicles that are themselves increasingly blocked by Western tariffs — will depend on licensing arrangements, joint ventures, and trade policy that none of the Tech Day materials addressed.
Analysis
The charging-speed race between CATL and BYD is no longer really about whether six-minute refills are technically possible. Both companies have now demonstrated that they are. The more consequential question is what six-minute refills change at the level of infrastructure and ownership economics.
Two things stand out. The first is that CATL has paired the cell announcement with an aggressive integrated charging-and-swapping network plan, signaling that it intends to sell not just batteries but the whole refueling stack. That is a direct answer to BYD’s FLASH Charging deployment, which couples the Blade 2.0 with proprietary 1,500 kW chargers. Whichever company’s network reaches useful density first will shape the charging habits of an enormous chunk of the Chinese EV fleet.
The second is Wu Kai’s acknowledgement that LFP is approaching its theoretical ceiling on energy density. Fast charging, self-heating, lower internal resistance, and integration with swap networks are all ways to extract more perceived range from an LFP cell without the chemistry itself changing. The strategy is coherent, but it also implies that the next significant jump — if one is coming — will have to come from a different chemistry, which is why CATL is simultaneously pushing sodium-ion and condensed-matter systems. The third-generation Shenxing battery is the near-term product. The rest of the Super Technology Day catalog is a hedge against the ceiling Wu Kai just named.
