Once battery technology reaches a point where it can hold enough energy to power a car for 300 miles, be recharged in 5 minutes, and be easily recycled and replaced at a fairly low cost every 10-20 years then electric cars will go mainstream.
Maybe this is that technology. Am I right in assuming these batteries would be significantly lighter than what is currently being used?
The 5 minute recharge eliminates all mainstream battery technology. Only replaceable-electrolyte batteries can do such a trick, but you’re physically pouring liquid to make that happen.
Lighter and cheaper is indeed the claim.
Still gotta put the energy in a battery in the first place. Therein lies the problem.
then electric cars will go mainstream.
Um, you’ve described a capacitor not a battery. And maybe thqat is the key ... controlled discharge is the solution.
