If EVs take hold in the marketplace, it will direct a flood of resources into battery development.
I remember during the 70's oil crisis, reading about EVs and the chief impediment being battery technology. The author noted that there had been no significant breakthroughs in batteries for many decades, and so the prospect of viable EVs was dim.
What changed that? The proliferation and market for battery-hungry devices in the form of laptop computers, which spurred development and improvements in NiMH batteries, followed by Lithium chemistries.
With EVs needing orders of magnitude more battery capacity the stakes and potential rewards are huge.
If we do get these super-fast charging batteries the next challenge would be building service stations capable of delivering that much energy in that short a time. Tough one. On the other hand, if there is a breakthrough in range, then the game really changes. If you could charge at home and have a 1000 mile range, how often would you even need a charge on the road?
I noticed you're still working with polymers.
