The nanosheet dielectric capacitors showed an energy density 1-2 orders of magnitude higher than their predecessors...

Nothing to sneeze at.

Ultrahigh capacity Capacitors would be a tremendous benefit to extending the range of EVs.

They would be able to safely take a charge much faster than any Lithium-based battery, and would be a very good match for maximizing energy recovery during regenerative braking.

Current regenerative braking is limited by the battery and onboard charging circuits' limits on charge rates. Excess energy is bled off as heat through the brakes.

You would need to combine the supercapacitors with traditional Lithium batteries for a practical vehicle, though.

Isn’t EVERY capacitor a dielectric capacitor?

So close to the Flux capacitor now....

Perhaps the author intended to say "dilithium capacitor."

Will it flambe itself while sitting in your garage and burn your house down?

1-2 orders of magnitude higher

/\

Wow.

I wonder if the fires will be of 1-2 orders of magnitude higher in severity also.

Until the fire problem of current composition of batteries is addressed I think most will still pass on ev’s.

That and electricity generation to charge these batteries is addressed.

More hydro not less

Drill baby drill !!!

Yeah, the energy density goes from the electric hand warmer zone into the electric hand grenade zone.

Never heard of such a thing. Can you elaborate?

Is a ceramic capacitor dielectric?

The great advantage to this technology is that you no longer would have to worry about battery fires. A capacitor bank of similar energy storage ability might be able to vaporize (or at least incinerate) the entire car within a second if it failed badly.

The National Ignition Facility (https://en.wikipedia.org/wiki/National_Ignition_Facility) uses “a capacitor bank that stores 400 MJ (110 kWh)”, which equals 147 horsepower for one hour. (I’m not sure how many miles this would be in practice.)

Note: The NIF uses capacitors because they can discharge their energy real fast in order to generate a 500 trillion watt laser pulse. Flywheels or batteries can’t do this.

Lots of (slightly scary) capacitor safety info can be found by searching online.

I wonder how it would respond to being skewered by a screwdriver? A small package (like a cell phone) with a Capacitive energy source of 100 watts most likely be weaponized... dang.

Eventually, they’ll find something that will work in the real world.

The using capacitors as a ‘battery’ has unique challenges though. What happens if the cap dumps it’s load all at once?
