This battery science paper by cambridge uni made the headlines in 2015. Using reduced graphene oxide, you can't help wondering how 2D +nanene might improve these results if used and plenty more like it i imagine ; gnanomat found it improved their tech ! Edit : oh, and zap and go too ! Aimo. Best ellis.

"Video : New lithium-air battery from Cambridge is 'most efficient'

Scientists at the University of Cambridge have designed a new battery that clears the path towards long-lasting, efficient rechargeable devices, from cars to smartphones.

The breakthrough comes in the shape of a lithium-air cell - a concept that can pack in much more energy per kg than current lithium-ion batteries.

But until now, problems of efficiency and degradation have plagued efforts to build such batteries.

The design, which has so far only been built in trial form in the Cambridge lab, appears in the journal Science.

Waseem Mirza reports. 29 Oct 2015"



THE ORIGINAL PAPER:

"Science  30 Oct 2015:
Vol. 350, Issue 6260, pp. 530-533
DOI: 10.1126/science.aac7730"

"Solving the problems with Li-air batteries

Li-air batteries come as close as possible to the theoretical limits for energy density in a battery. By weight, this is roughly 10 times higher than conventional lithium-ion batteries and would be sufficient to power cars with a range comparable to those with gasoline engines. But engineering a Li-air battery has been a challenge. Liu et al. managed to overcome the remaining challenges: They were able to avoid electrode passivation, turn limited solvent stability into an advantage, eliminate the fatal problems caused by superoxides, achieve high power with negligible degradation, and even circumvent the problems of removing atmospheric water....."

"Hierarchically macroporous reduced graphene oxide (rGO) electrodes (binder-free) are used because they are light, conductive, and have a large pore volume that can potentially lead to large capacities."

Timc
Thanks for your post .

Yes its very wrong if people could have lost out listening to the board troll s .
I hope that’s not the case here
Certainly not in my case thankfully .

The charts show Bmn were once 1.27p
In September 2016
Now 37p
What a journey for you guys .

All the best
We’re enjoying great success and our journey here .

Spid claims on Hot Copper that he’s sent a list of collaborations that VRS have onto FGR so they can approach the named companies with an alternative product as it’s difficult to find companies that want to work with graphene.

I didn’t realise FGR were so hard up for sales leads that they needed shareholders to provide them with publicly available news on what VRS are doing!

Added to which, VRS have been approached by the majority of their customers for graphene, they haven’t had to go out and chase it.

More convinced now that FGR is a pump n dump and terrible investment prospect. How would Tim / Mike et al put it.... Laughable.

HES DOING THE SAME NOW ON THE VRS BOARD! IGNORE HIS DRIVEL

The other thing about trolls like this guy is that he can't take a dose of his own medicine ! Notice how he's blocked me on Twitter and run to the headmasters office of Twitter telling tales of me ? But he thinks it's totally acceptable to constantly troll these boards scaring normal hard working people out of there investments with the lies he puts on these boards for his own agenda ? People must stand up to scum like him he's a laughing stock and a little weasel ! He's just a bad as burglar, trashing your house then leaving like on these boards ! https://twitter.com/timcvntish/status/1058280518024863744?s=21

Anyone at a loose end and in to Elon Musk, this interview is certainly interesting.
Only had chance to listen to the first half so far.

He gives you a real understanding of how complex running a large company is, how reliant you are on every cog in the wheel, all relevant in many ways to VRS.

I know Neill appears to be a big fan, the guy is without doubt inhuman...

Unless you have one of those new kinds of wife?

Your wife is Spartaca.

grabster - no, *I* am Spartacus, and so's my wife...

I just read somewhere we are ONLY valued 9 times more than some other so called graphene Co's ........ fekk me that can't be right! I would have said 20+ times higher ffs ... going to buy more on that news... :-)

[grabster] 04/11/2018 09:25

"we are still number one with our capacity level, compared to our competitors."

And I am Spartacus.

Ellissj
How far could all this science and technology go.

A lot of excited people out there at the moment .
Right from the scientist to the shareholders

Mind boggling isn't it.

From the latest NGA newsletter:

SIXTH ELEMENT GRAPHENE & THE GLOBAL GRAPHENE EXPO: INTERVIEW WITH BERNHARD MÜNZING



"Sixth Element currently has a capacity of 260 t/a for graphene oxide and 130 t/a for graphene at our facility in Changzhou, using a modified hummers method. At our site in Wuxi, we produce what we call ‘graphene film’ (graphene deposited on PE/PET film), starting with a CVD process. Currently, we are still number one with our capacity level, compared to our competitors."

Indeed ff, the 2D world and the discoveries/applications that will follow is mind boggling. The space race to the stars above seems insignificant to the 2D space race below us right now. Must be very exciting to be a scientist involved in it. Atb. Ellis
