CATL has obtained a new patent for solid-state batteries and secured a large supply of copper foil. Both developments indicate CATL's progress in the pilot development of a sulfide-based solid-state battery, which, according to media reports, is expected to achieve an energy density of 500 Wh/kg.

500? Wow!

I'm more interested in their sodium-ion cells, which are apparently going to be used in a Chinese EV to be available later this year. Lower cost and better performance in the cold are the main advantages. I guess it will take a few more years if production is going to ramp up such that it can have a big effect on the global market. But I imagine it will be much longer before solid state happens.
