CATL says its new Qirin battery has 13% more energy density than Tesla’s 4680 cells and can go 1000 km without recharging.In 2019, CATL introduced its cell to pack technology to the world with a volume efficiency of 55%. This week, the company unveiled its new Qilin battery pack that boasts a volume efficiency of 72%. It is said to have an energy density of 255 Wh/kg, which the company says is 13% higher than the energy density of Tesla’s latest 4680 cells.
The new design supports a fast hot start in 5 minutes and charging to 80% in 10 minutes, CATL says. In extreme conditions, the cells can be cooled down rapidly, effectively blocking abnormal heat transfer between cells and reducing the chance of thermal runaway events . In addition, CATL says the integrated energy pack composed of the battery cell and the multi-functional elastic sandwich layer builds a more stable force structure in the direction perpendicular to the travel direction, improving the structural strength and impact resistance of the battery pack.
CATL supplies batteries to most of the major automakers both in China and around the world, so it is likely the Qilin battery packs will find their way into production cars beginning next year. There is no official word on which companies have signed up to use the new battery packs from CATL at this moment. What is known is that CATL is
to build its first battery factory in North America. It is the largest battery supplier in the world and intends to stay there.
Hence why Tesla isn't special....
That's good. But of course the battery autonomy depends on a lot of parameters. Weight of the vehicle, battery management software...
