I've put this info up before but I hadn't revealed to anyone that it was a graphene super capacitor. After much trial and error, I figured out an excellent way to make graphene in quantities I could use to put on a film and them have rolled into a capacitor. I paid a good deal of money to have a manufacturer, create the capacitor, using my graphene film.

The capacitor in the battery is approximately 3500F, rated at 2.2 to 3.8 volts.

The steps throughout, document the construction of the battery itself.

Please support this on my Kickstarter, so that I can get this funded and actually get graphene capacitors produced and available on the market. They are AMAZING! Such an enormous amount of energy storage potential in a small package. Not to mention, the battery charges in seconds!

## Step 1: Building the Circuit Board

What you see in the picture is the capacitor and the beginning of the circuit board. The purpose of the circuit is to efficiently drop the 2.2-3.8 volts from the capacitor to the 1.5 volts you see from a AA, C or D battery. There is also a voltage monitor IC on the board because the capacitor can become damaged if the voltage drops below 2.2. The monitor basically enables the regulator as long as it detects a voltage above 2.2

After everything was hand soldered on to the board, I cut it and sanded it down to a circular shape that would fit inside of the battery tube.

## Step 2: Putting It All Together

Here we have the capacitor inside of the battery tube with its leads sticking out. In the middle, you see the finished circuit board, cut down to size and ready to be hooked to the capacitor.

## Step 3: The Charger

Recharging the capacitor was another issue. It needs 3.8 volts to charge it but you can't charge it through the top and bottom because that is the + and - terminals of the battery that is putting out 1.5 volts. So, towards the top of the battery, the casing is base metal. That bare metal is hooked to another regulator that drops 5 volts to 3.8 and then leads to the positive lead of the capacitor.

The charger itself makes a connection to the negative battery terminal and then there are 2 connects that contact the sides of the battery, allowing the capacitor to charge.

Another great thing about having a capacitor as a battery is the fact that it recharges in less than 30 seconds!

## Step 4: All Done!

There it is, next to a standard alkaline battery. I've built a total of 4, with 2 of them powering one of my daughters toys for a few weeks now. It lasts just as long as the alkaline you see next to it but charges in under 30 seconds. Please support my Kickstarter campaigne so that I can get the batteries and at the very least, the capacitors out to the world so that everyone can have access to a graphene capacitor. The possiblities are endless with them! This isn't an advertisement by any means. It gives a general idea of the construction of it and the fact that the graphene capacitor is out there!

<p>Hmmmmmmm?</p>
<p>Not real info but after investment? I think not...</p>
<p>I want to work on this project, but where to source this graphene super capacitor ?</p>
<p>Is this a mistake or a joke? Prematurely posted before any specific details were added?</p>
<p>This guy is either very gullable or wants to rip people off. Here's a great technical explanation about why this is BS: http://www.eevblog.com/2014/07/28/graphene-lithium-ion-capacitor-kickstarter-bs/</p>
true story :D
<p>and of course its by the crazy aussie bloke who knows his stuff. and is more than credible. gotta love dave </p>
<p>Unfortunately you didn't show how the capacitor was made, or a schematic for the circuit, or any hard test data showing how you measured the capacitance or the life of your battery replacement. Rather than assuring us that: &quot;This isn't an advertisement by any means&quot; perhaps you can fill in a few more details so we can see for ourselves how good this invention is.</p>
<p>The contacts look a bit flimsy for 160-ish Amperes ?</p>
<p>Where did you buy the cap? :)</p>
interested to know if you have checked how many amp hour you can get out of one of these
<p>Approximately 1150 mAH</p>
<p>That would be awesome!</p>
thanks for that. quite impressive capacity for it's other features. I've wondered before about using capacitors as battery cells. well done
<p>What evidence/data have you got to back up your claims regarding charging, energy density and discharge?</p>
I think that data would definitely encourage possible investors in the kick starter
<p>Is this different than the existing 3500-4000F range supercapacitors available commercially? If I remember correctly those also have similar charge times.</p>
<p>Capacitors in the 3500-4000F range made by Maaxwell Technologies are somewhat larger than a D size battery and they are rated at 2.5-2.7 volts.</p>
I see, I didn't realize how small your capacitor was. This would definitely be useful in place of AAs.
<p>It's different in the fact that the capacitor is small enough to fit into the footprint of a AA battery.</p>
seems a bit far fetched...
<p>Not far fetched at all. The technology is out there. Lots of trial and error leads to someone eventually getting it right.</p>
It's been stated clearly several times in different places: this isn't an available capacitor. He has had a capacitor manufacturer build a capacitor using his graphene conductor in place of the (I assume) carbon. You can't buy these. They are prototypes that he is trying to get built for use in a battery format.<br><br>With the necessary funding he will be able to get scores of these capacitors made and then all the buck-charge boards. If he succeeds then I imagine the patent (if awarded) will be sold or licensed to battery manufacturers for tablets and cell phones. I mean that's what I would do.
<p>its a Taiyo Yuden 40F capacitor, pretty available (look at the images on his kickstarter and you can even see the lettering) also its a lithium cap not graphene. </p><p>http://hackaday.com/2014/07/26/ask-hackaday-graphene-capacitors-on-kickstarter/ enjoy </p>
