Reply to comment by OptimalConcept143 in Scientists have developed a solid-state battery material that doesn't diminish after repeated charge cycles, potentially offering a durable alternative to the lithium-ion batteries used in electric vehicles by unswsydney

Range = the best power to weight ratio.

I’m assuming the battery has a reasonable power to density ratio but there is actually a LOT of room for batteries in a car when you build a dedicated EV skateboard style chassis. You run out of weight capacity long before you run out of space to install batteries. And a pound of battery saved is a half pound of suspension and structure saved. It really really matters. A lighter battery makes the entire car lighter.

That's true isn't it?

I'm still skeptical. I've seen way too many posts about battery tech over the past decade and it never pans out.

Yet I will be able to buy a electric chevy pickup with 640km of range, 250kW charging and a 2000 cycle rating starting next month. That’s a million km battery.

Sometimes battery tech DOES make it to the public.
