China's CATL Says It Has Overtaken BYD On 5-Minute EV Charging Time (msn.com) 115
CATL has unveiled a second-generation Shenxing battery capable of delivering a 520km range in just five minutes of charging, surpassing BYD's recent breakthrough and positioning both Chinese firms ahead of Western rivals in EV battery tech. The battery manufacturer also introduced a sodium-ion battery called Naxtra, offering up to 500km range for EVs and potential to diversify global energy resources. The Financial Times reports: The claims by the Chinese battery groups would put them ahead of major western rivals. At present, Tesla vehicles can be charged up to 200 miles (321km) in added range in 15 minutes, while Germany's Mercedes-Benz recently launched its all-electric CLA compact sedan, which can be charged for up to 325km within 10 minutes using a fast-charging station. [...] The second generation of the Shenxing battery, which boasts a range of 800km on one charge, can achieve a peak charging speed of 2.5km per second, the company said at a media event ahead of this week's Shanghai auto show.
"We look forward to collaborating with more industry leaders to push the limits of supercharging through true innovation," said CATL's chief technology officer Gao Huan, adding that he wanted the new batteries to become "the standard for electric vehicles." Analysts at Bernstein said the latest progress meant that charging speeds had more than doubled in the past year and "increased tenfold over the past 3-4 years." Huan said the new Shenxing battery would be installed in more than 67 EV models this year. He later told reporters that energy density would not be sacrificed as a trade-off for fast charging.
During its tech day, CATL also unveiled its new sodium-ion battery, which it said would go into mass production in December. The battery brand called Naxtra is able to give a range of about 200km for a hybrid vehicle and 500km for an electric vehicle, according to Huan. [...] At the event, Huan claimed the new sodium-ion battery would enable the industry's shift from "single resource dependence" to "energy freedom" and reshape the global energy landscape. He added that he was in discussions with several companies about using sodium-ion batteries in their vehicles.

I think you're correct from a point of view of psychology, but in practice, most people won't make use of charging this fast any more than they routinely use the full 300+ mile range of their car. It'll be a rare kind of thing. And most of the time, they'll just charge at home and on many trips, just charge at their destination, or en route with a slower charger while they stop for a meal or a pee and a stretch.

We can see this in practice from the low utilisation trends for UK public chargers.

Quite the opposite :
"However, the analysis uncovered one exception to this trend, with the time-based utilisation of ultra-rapid chargers (100kW+) increasing from just over 12% to more than 16% over the same period. This shows that ultra-rapid chargers are in high demand, even with the number of these devices increasing by 78% between the end of 2021 and the end of 2022 – the highest percentage increase of any type of charger."
It's the public slow chargers which see less use, because they are a comple

I absolutely don't agree with ZapMap that it's reasonable to describe 16% time-based utilisation as "high demand", and we need more longitudinal data to assess trends over time (note that it talks about device growth in CY222 only).
Comparing production to lab? (Score:2)
I'm not asking you to say the emperor has no clothes, though it's clearly intentionally misleading propaganda, but spare me the cringe of copy pasting it without comment. Just add that the western systems are production, not lab.
If the Chinese actually want to put this in production, the charging stations almost certainly will need batteries of their own to alleviate the massive peak power load on the grid.
