Graphene Super-Capacitor Cells - How Pencil Lead And A DVD Burner Will Change The World.

Graphene Super-Capacitor Cells - How Pencil Lead And A DVD Burner Will Change The World.

Tesla currently uses lithium to make batteries that power their vehicles. While lithium is fairly inexpensive to manufacture, it has its drawbacks. Catching fire when exposed to air in a fatal accident, the inability to charge quickly compared to the fueling time of a combustion engine, and a limited life cycle, are but a few of the difficulties that have to be taken into account when using lithium as a power source for electric vehicles. But, what if there were a simplistic, cheap material that equally performs as lithium but is so environmentally friendly that it can be re-used as garden fertilizer? What unimaginable, absurdly fictional material could possibly exist with these properties?


What is graphene? It is essentially composed of the same graphite material found in millions of yellow pencils used by children around the world. The only difference with the writing material is the arrangement of the carbon into single atom-thick sheets rather than a random jumble of atoms. This material does not look like much on the surface but when it is arranged in this fashion, the carbon takes on some strange and amazing properties – such as the ability to hold and disperse large amounts of electrons.

Until recently, graphene was difficult to manufacture on a large scale. Thanks to some ingenious researchers at UCLA, making graphene is as simple as painting a liquid carbon solution on a DVD and running it through a Lightscribe DVD burner. The result is a material that has the same energy density of lithium, but can be charged in a fraction of the time along with the added benefit of being manufactured at pennies on the dollar.

What does this mean for Tesla? Since they would no longer have to base the price of their vehicle on the cost of batteries, Tesla will be able to manufacture cost-effective electric cars for the masses that are equally as powerful as any car that uses lithium batteries.

First of all, Tesla doesn't manufacture batteries. They buy them.

Second, we're all well aware of graphene here, thanks.

It's really too bad we don't have a search function readily available here for the new folks so we can avoid this kind of repeat of posts. Fortunately, a member here created one for us, Check it out.

We're all very excited about the prospect of better battery tech but the reality is that we're still a ways (a year, three, five or ten?) away from such tech being manufactured at a scale and price that allows Tesla to maximize its margins and become profitable.

N A L Tesla would love to buy beter, less expensive batteries. Please suplly the name of a reliable battery manufacturer that can provide the following:

2014 - for 30,000 Model S and X 8,000 batteries each. Total 2014 needs 240 million battteries (or equvaliant if denser cells).

2015 - same as 2014 for Model S and X plus for 100,000 GenIII at 6,000 each total 600 million additional.

Until that manufacturer is ready to deliver tested proven batteries Tesla MUST use what is available to meet the goal of becoming a profitable CAR manufacturer.

We can all hope and dream of the future, but Tesla must succeed in todays world.

I am a stock holder and look forward to being an early GenIII buyer.

800+ million batteries annually is huge. Maybe I should buy some Panasonic stocks too...

I think if someone does "better automotive batteries" it will be Panasonic, mainly because it will have both reason and resources to simply buy the company that makes clearly better automotive batteries. It's the only big battery manufacturer that does BEV batteries in large scale. If Tesla succeeds it will be huge deal for Panasonic as well.

I have been reading a lot lately about graphene super capacitors. There's something I don't quite get. Why does graphene increase the energy density of a capacitor ? Graphene is an excellent conductor.
Think about the basic structure of a capacitor ---[ ]----
The capacitance C = eA/d

How does making the plates of graphene make C bigger ?

Can we figure at least 5 billion batteries if Tesla production ever gets to 1million EVs a year. Does Panasonic even have that much battery production capacity ?

N. A. Lee,

If a fresh group of people want to explore an old topic, maybe get some new perspectives, that's fine with me. Not that you need my permission.

There will always be a steady stream of new people coming onto the threads as regulars.I enjoy the spontaneity, new insights and perspectives.

I notice that the General thread does not get much action anyway.

Speaking if the conductance of graphene, I'm curious whether or not anyone here is aware that there has already been an application of graphene technology deployed on the mass market in the form the ColdHeat soldering iron which actually makes use of the graphene-like Athalite compound which possesses the remarkable ability to both tolerate extreme heat and rapidly dissipate it?

Pls note making supercapitor with high energy density is important but more important is cycle life! how much thousand cycle we have retentivity of charging and dicharging.
pls see the paper we have demonstrated 10000 cycles at 7.5 A/g by conventional battery packaging method used in industry like using SS grid to make graphene electrode, ionic liquid as electorlyte and packed in coin cell. And we were able to get 83 Wh/kg at 2.5 A/g current density.

k.santhakumar | 25 novembre 2014

Many claim high sp.capacitance but at very low current density and very few thousands cycle life at low current which may not suitable for high power application. What we need is at high current density we need something simialr to Li ion battery energy density and durabilty (cycel life). Acheiving 80-90 % retentivity after 50,000-100,000 cycles of orginal value at high current could be really useful for EV. And the manufacturing should be simialr to battery technolgy where it has been proved to withstand hard environment like integrity of the supercapacitor which is important in a real time application condition.
More than weight factor, integrity and reliabilty of the supercapacitor is very important for long time application

Just in case the grapheme battery thing doesn't pan out...

jettagtx | 7 aprile 2015

Well guess we all know Tesla is building their own battery manufacturing plant in partnership with Panasonic.. wonder if they might look at this new tech?
