The ranges stated are and were not for the battery. It was for the vehicle.
No vehicle is mentioned. I'm guessing Chery didn't believe 400 Wh/kg would make many people sit up and take notice, so the PR staff carefully calculated a number that substantially exceeds the range of current EVs without being implausible. I will stop being a tedious stickler.Chery has announced major breakthroughs in its next-generation solid-state battery technology, revealing a cell with 400 watt hours per kilogram energy density and the potential for up to 1500 kilometers of range.
Well, that 400Wh/kg is a fairly standard threshold right now. I've seen a little higher, perhaps 456? They are aiming for 800 but the first thing they have to fix is being able to mass produce them and cure the degradation problem.No vehicle is mentioned.
