Video: The battery that might change everything

Some of the great scientific breakthroughs of the last century came about entirely by accident. Many of you are probably familiar with the origins of the Post It Note, and how it was invented as a result of a failure when attempting to create a super strong adhesive. Well, there may be another such story taking place in the present day. Scientists working with carbon compounds developed Graphene, a safe substance with a lot of structural strength for very little mass and weight. And then some wise guy discovered that it had another use.

The recap: Graphene, a very simple carbon polymer, can be used as the basic component of a “supercapacitor” — an electrical power storage device that charges far more rapidly than chemical batteries. Unlike other supercapacitors, though, graphene’s structure also offers a high “energy density,” — it can hold a lot of electrons, meaning that it could conceivably rival or outperform batteries in the amount of charge it can hold. Kaner Lab researcher Maher El-Kady found a way to create sheets of graphene a single carbon atom thick by covering a plastic surface with graphite oxide solution and bombarding it with precisely controlled laser light. That last sentence may sound pretty complicated, but the article’s author provides a translation for the layman.

He painted a DVD with a liquid carbon solution and stuck it into a standard-issue DVD burner. The result was a shockingly thin supercapacitor which could store up a large amount of electrical energy in no time flat. The potential for this sort of discovery should be obvious. Unlike heavy metal batteries, the carbon compound is biodegradable and cheap to manufacture. And a battery made of layers of this material could charge your cell phone for a full day’s use in – wait for it – two seconds. A ramped up version could charge an electric car in a minute or two. (No word on how likely it will be to catch on fire, but bonus points if it doesn’t.)

Here’s the video I mentioned. It’s not long and explains the process better than I ever could. I have to say, this is pretty exciting stuff if it comes to fruition.

Was any sulfuric acid introduced during the process. That sulfuric acid can be nasty stuff. Have not gone to take a look and is why am asking.

I did once it blowed up really good (of course the voluminous amounts of toxic vapors were not really expected...)

Since the (fun) high capacity fireworks of my yute are gone, if kids were edjeumacated, they'd turn to capacitors.

Who doesn't like high energy density devices?

Short out a charged capacitor and you get a nice explosion. The larger the cap, the bigger the explosion.

That much capacity to absorb and hold a charge over a short period of time, also indicates that there would be the capacity to DISCHARGE that electron load just as quickly as it could be put in.

And a rapid discharge of electricity always involves heat, so how is the discharge to be throttled back to useful levels so the wiring does not burst into spitting arcs and open flame? (I know, I know, that is why Doc Brown invented the Flux Capacitor, which makes time travel possible.)

We may have fusion energy before that problem is solved.

Yeah, I know. But I remember reading in my youth about the great inventors and inventions. And the doubters who said that steam would never catch on. And that gas lighting in a home would never work. Would burn your house down. And that no one would want dangerous electricity into their homes. And who would ever ride around on a horseless carriage. And I can even remember myself saying back in the seventies, these damn toy computers (PCs) will never work in a business environment!

The next GREAT battery invention for electric cars is ALWAYS just around the corner. The problem is that these new batteries never actually make it “around the corner” because the REAL WORLD is vicious to batteries, much more so than it is to gasoline. Temperatures from -40 to 120F have to be accommodated, running at varying loads, especially climbing steep hills slowly in hot weather (which often overheats gas cars too), and the demand that they charge fast, very fast.

Ohm’s law applies regardless of the power source. At any given voltage, the load will draw the same current whether it’s from a capacitor, a battery or the power grid. The main problem with capacitors is that they pack a huge wallop when they’re shorted out.

Given that it was made with GO (graphene oxide), most likely. That's not the safest chemistry.

Indeed. And we might add that carbon and polycarbinate are both wonderful sources for making CO2 in the presence of high temperatures and air.

They want lots of energy stored in a small space. They don’t seem to understand, that is what a bomb is. If there is a fire or an accident, the energy will be released.

With gasoline and other “fuels”, there is no oxygen, so the release is slow. With batteries, capacitors, flywheels, accumulators, etc, the energy is all there, and ready to explode. I’ve seen trucks cut in half by flywheels (old style wood chipper accident). I’ve seen small radios blown apart by tiny capacitors. I’ve seen laptops incinerated by batteries. They’re trying to squeeze a balloon — every improvement in one area will increase the problems in another.

Speaking of great inventors, great inventions, steam, and things that will never work—stumbled upon this yesterday:

Lincoln’s Secret Weapon:

https://www.youtube.com/watch?v=wCZaSHIUpVk

Ironclad warship, steam powered, screw propeller, rotating turret, powerful naval guns. Of course, all of it was highly dangerous and none of it caught on. Impractical. The inventor was even banned from doing business with the government for a period after a gun exploded during a demo.

"With gasoline and other “fuels”, there is no oxygen, so the release is slow"

It's handy that the Earth's atmosphere has a relatively high concentration of O2. Fuel-air bombs seem to be very effective.

Did you ask for a commodore, as a consolation prize? My eldest did, and I played with it more than my eldest. Then came larger processors with greater capacity and then I have no idea what happened next. Been here typing ever since.

Great chart! In the energy world we talk high heat value and low heat value. Anthracite vs. Bituminous is very interesting comparison. I wonder where coke (almost pure carbon) is on that chart. Polycarb also burns much differently than the polymers listed, but you get the idea. Of course this has little to do with the stability of the storage device. Some Li-ions have the explosive capacity greater than TNT.

I’m more familiar with ordinary li-poly cells which burn rapidly but do not explode, although it may appear that way to someone surprised when one lights off. Most consumer li-ions are quite resistant to rapid oxidation events.

Hmmmm, I’m thinking of a 3 or 4 stage coil gun, compressed air to get the copper slug moving and I’m thinking a 200 grain slug moving at say 3,000 ft/second. No powder, no bang very little noise. Just the crack of the bullet.

Now if you could spin the bullet prior to launch so the bullet is gyroscopicly stable then you would really have something.

Who said anything about doubting it would succeed? I was just pointing out (as requested) the Achilles Heel of capacitors.

It’s not insurmountable or we’d not have but a tenth of the electronic tech we have today. But it’s the big problem with capacitors.

One of the problems of using super capacitors for energy storage is that they have much higher self discharge rates than batteries. I can see applications using super capacitors and batteries together in order to take advantage of the best features of each.

LOL!! Boy, the stories I can tell you about accidentally shorting and blowing up capacitors while working on amplifiers and other equipment. A decent sized capacitor sounds like a gun going off when it pops.

On a more serious note, Capacitors are not meant for storing electricity on a long term basis. Yes, they charge quickly at high voltages but you're not going to run a car on a "charged capacitor."

This isn't "back to the future" and there's no such thing as a flux capacitor. Yet another "breakthrough battery scam" IMO.
