RE:RE:RE:Sr. Test Pilot for Stratolaunch's mach 5+ program Especially for navajojoe, I'll post two posts here here that I posted on another board, respectively 7 and 12 days ago.
I posted these on a Flemish board and quickly translated them via Google Translate.
One of our readers made over 300% on GMG in the past year after I introduced the stock over there.
That's of course no guarantuee for future performance. This also isn't any advice, just some due diligence I've made.
As GMGs stock declined, I've decided to build up my position again and now I'm hoping for a next major run in 2023.
GMG is one of the two dozen companies worldwide who claim that they can scale graphene. They don't use mined graphite as a pre-cursor for it so they do appear to have an edge in cost.
GMG also signed over 100 NDAs with interested parties for their battery product which is in coin-cell stage and tested by these parties for use in their products.
Pouch packs, which can be fromatted to use in mobile or any other larger products, are coming along as they scale with their partners Bosch, Rio Tinto and Wood.
Graphene Manufacturing Group demos fast-charging
A GMG battery engineer shows how in (barely) 2 minutes he charges two button cell batteries (placed in series) from 1.7 volts to 3.7 volts on an ordinary laptop:
It is no coincidence that he uses 2 button cells of the 2016 format. Together they form one of 2032, a format that you encounter in small electronic devices such as remote controls, hearing aids, watches, toys, etc.
The 20 in 2032 stands for the diameter of the cell in mm and the 16 or the 32 for the height.
Once below a voltage of 2 volts, most such devices will indicate that the battery is flat. They generally work fine between a voltage of 3 and 3.7 volts.
A traditional 2032 lithium-ion button cell takes 2 hours to charge. Still a strong contrast with the 2 minutes in the video.
GMG therefore shows something very beautiful.
There is still a long way to go before producing this technology in so-called pouch packs, not in small - insignificant-looking - button cells.
Then they could be useful in so many more applications. Just think of mobile phones, laptops and EVs, although that is only planned for mid-2025-2026 at the earliest.
The Australian company will first focus on the mass production of the small button cells in order to demonstrate the technology and its scalability.
Graphene Manufacturing Group: what a battery update! GMG has been able to significantly improve their battery technology.
With an energy density of 290 Wh/kg (that's how much they can store), they are now slightly better than the well-known Li-ion batteries (270 Wh/kg).
Compared to the previous iteration, their energy density has even increased by 93%!
If you take into account that classic Li-ion needs cooling, then their product is now 15% better in terms of storage capacity for the same volume of battery.
The unseen in their type of batteries is:
a) They do not contain lithium. That's good because lithium prices have already gone through the roof (x10).
b) They also do not contain other rare or expensive materials such as cobalt, nickel, manganese etc.
c) They can be charged at lightning speed. In theory up to 60-70x faster. In practice, the limiting factor will be the supply of energy.
Lithium has become a strategic raw material (such as gas and oil, for example). Countries are not waiting for dependence on another country. Almost all other alternative battery improvements still use lithium.
This is starting to look a lot like a game-changer!
I'm dreaming of buying a GMG home battery in about 5 years, connect it to a handful of 550-570W solar panels and get off the grid! Right now, I am still too scared of the Li-ion home batteries as they might catch fire.
