Solid-state battery cell sets records, can offer over 1,300 mile range (electrek.co)

If this isn't just corporate hype, this could be great for making smaller batteries, hopefully less resource intensive.

Yeah, this kind of headline is stupid. Any battery can offer any given range if it's large enough. This kind of thing should be written as distance/mass or, for consumer products, cost/distance.

Even that is meaningless because the vehicle you put a battery in is as important or moreso than the battery.

Aptera has a claimed 1,000+ mile range with a 100 kWh lithium battery. Meanwhile, the Rivian R1S has a claimed 270 mile range when equipped with a 106 kWh battery.

The main difference is that the Aptera is a light and aerodynamic car built for maximum efficiency instead of a 6,000 lb pickup truck. Any battery can boast amazing numbers if you are flexible enough with the use case.

That's true. I guess it should just be kWh/mass. Either that or we should have a standard vehicle all batteries are tested on for headlines if they want to talk about distance, which is obviously more understandable to the average reader.
