The future of energy storage is the high energy density ultracapacitor.
And it always will be.

Hybrid LiON + supercapacitors have already been used successfully on motorcycles to provide incredible short term performance. Tesla is going to do the same using its Maxwell Tech comoany it purchased to make a hybrid option on the 2022 Roadster which will simply make it the fastest quickest sportscar ever made by a wide margin. Were talking 0 to 60 in 1.3 seconds, quarter mile in 7.2 seconds at 188 mph and a top speed of over 275 mph.

Regenerative braking so I believe only ‘captures’ less than 20% of the energy available due to the limitation of the battery systems to ‘accept’ this energy in such a short space of time when braking. The capacitor would potentially capture the ‘lost’ 80% and increase the overall efficiency of the regenerative braking system. Interesting development. I drive a Prius hybrid. This would help in future hybrid as well as EV vehicles.

john Wordley: Super caps are there to capture braking energy,and all of it,not just 20%,up to the point they are full. After that,regen is fed into the battery pack,again up to the point they can't accept any more charge. At that point,your mechanical brakes would be used.

There are SO many companies working SO hard on this with SO much money at stake it's only a matter of time before we see a 5 minute to charge ev.

Every car mfg going stir crazy throwing billions at unproven risky stuff just ask gm about Nikola doing anything to keep having Tesla eating their lunch and leading them behind the shed. The Germans are so screwed they just dont know it yet

Good observation about having all the lights on the block go out when you plug your car in. People don't really appreciate the power required to charge a car and how that translates into current over time. Right now, if every car in the US were transformed into an electric car overnight, it would bring the electrical grid to its knees, also overnight. The square footage in e.g. solar cells required to fully charge a Tesla battery over a single day is a bit daunting. TANSTAAFL.

"a long-term roadmap toward a tenfold boost in energy density that could make things really interesting" is the real take-away from this article. EV's might finally be getting to the point of usable!?

This is another scam and limited use as the article correctly stated the lithium does not get charged in 15 seconds and there are li-ion , LFP batteries that can outdo this SC on specific power and last a good while vs .5 sec for the SC boost.

This tech, mixing batteries with super-capacitors, although nothing new, is a valuable way to up the coolness of EVs since it makes it practical for them to have wicked amounts of performance if the car is matched up with powerfull enough motors and controlling electronics. EVs need to be more cool than ICE units to draw the market over and this tech can help.
