A few days ago, an expert in the field explained to the Financial Times that the famous solid-state batteriespresented as the next real revolution in automotive electrification, were not quite ready to upset the market or habits.
Lithium, despite the difficulties it poses, particularly with regard to its supply and recycling, therefore seems to still have a few bright days ahead of it. A major player in the market, Tesla has been promising a revolutionary battery for years and seems to be approaching more or less quickly to inclusion in its cars on an uncertain horizon.
The competition is also growing. And not just any: CATL, world leader in the field, itself a major supplier of Tesla and soon of BMW, which is full of praise for its solutions, announced a few days ago that the Chinese brand Zeekr would be the first to adopt, en masse, its long-awaited new battery named “Qilin”.
If Zeekr is still unknown in Europe, the arrival next year under our longitudes of its 001 will undoubtedly be a good opportunity to test the Qilin in real conditions.
Comparisons and small tackle
Because CATL promises a lot for its new solution, as explained by Interesting Engineering. A lot and, perhaps, enough to overcome some reluctance about the transition from explosion to electric.
According to the figures given by its inventor and thanks to a different arrangement of its cooling systems, the Qilin could thus be recharged to 80% in 10 short minutes: enough, if the infrastructures follow, to escape a little from the famous “anxiety of autonomy”.
The latter would also be rather sturdy, again according to CATL. “With a record volumetric efficiency of 72% and a density of up to 255 Wh/kg, it enables the greatest level of integration in the world so far, and is capable of offering a range of more than 1,000 kilometres”describes the official press release announcing the partnership around the Zeekr 001, as well as another model named “009”.
Press release which, and this is probably no coincidence, even allows itself a comparison with the much commented 4680 cell from Tesla, which CATL nevertheless produces itself for the American manufacturer.
With the same size and the same chemistry, explains the text, the Qilin would be able to provide 13% more power than the 4680, which gives it superior performance in terms of material. battery life, charging speed, safety, lifespan, efficiency and low temperature performance. Just that. It remains to be seen how this will turn out on real-world roads, and not in a press release.
