Right away in the interview he talks about the one issue I addressed before, “weight/mass.”
In all of my research, I have never come across a better element, Li(in and on the market), to serve the purpose of energy storage.
When Solid State Batteries come online, and is placed into the EV world, the R&D’s of this era will have a tough time, to build a battery energy storage system better than Lithium.
Lithium is here to stay.
GMG will be awesome for power grids, keeping its cool in rapid charge and discharge states.

Wow. I guess they believe none of their investors are fluent with electrical theory. This is the biggest load of fluff, BS, what ever you want to call it that they have ever released. Charge rate is meaningless with out capacity testing, a battery exists because we need mobile power with capacity, not a device with a voltage potential. We can do this same thing with 3.8V 40F ultracapacitor. Voltage is just a potential for current to flow, put a real load on these batteries and test them against a comparable lithium battery......This video was all I needed to stop watching this stock. GLTA holders, peace out.........

That video was an 8 minute waste of my life ;)
His last statement was the crucial one and the one I pointed out about this process, manufacturing this battery technology for the masses, or as he called it scaling up.
It will be awhile for these guys.
“Energy Density”, that eBike battery increase its size by ten and fit that on your bike. I am in total agreement with you on safety, I would like better circuit designs to handle thermal run away events, that trigger cooling mechanism to thwart safety issues. Or a manual trigger for the user, either way safety.
Remember gasoline and it’s dangers, through gas station fires and kids burning themselves. Lithium is in the same early adoption as gasoline was.

2 min charging time on a 2016 coin cell. Nice.
The fact they are in 2016 Coin Cells tells me they are no where near market ready with the standard coin cell of a 2032(or even the cr123 is a crucial design and test). I have not seen a cr2016 coin cell in a circuit design in my lifetime and there is only one time I can remember seeing a cr2016 in a toy.
I am going back to that charge time, if 2 min is the charge time on a 2016 coin cell, I would love to see the charge time on a 18650 G+Al Battery. Those stats are very important to EV’s if GMGMF is going to be battery manufacture to reckon with.
18650 takes about 3 hours to charge, but we are talking about a 3000mAh battery, G+Al is(1.8v to 2.0v cutoff) 150mAh. So the 18650 is 20x the power of the coin cell, in theory I would say that the 2 minutes times the 20 is 40 Minutes of total charge time for a 18650 G+Al battery. Theory as we know doesn’t always prove to be the exact real world expectations of the product in physical form.
Here is the next question that arises, I pointed out energy density previously and if the G+Al is going to be competitive with lithium, they have to reduce their footprint on their batteries. The energy density of lithium to G+Al was a 1000% difference. Meaning lithium packs more of a punch in a smaller space. May take more time to charge, but to Product Managers retail space and product design have to be symbiotic. And I have a hunch, lithium is chosen, lighter and smaller.
They have to cut ties with 2016 designing and testing and get to the heart of battery usage 2032. They are wasting precious time on design and testing. Just an FYI, just because you perfected the 2016 platform doesn’t mean it will behave the same on the 2032 platform. No one battery is a like, they behave different. Sure you put in double A’s and it does what you want but why did the last set work longer/shorter than this set?!?!
At my last job, I told them about batteries having this mysterious side to them, they have this mystery box of unknown power. They laughed at me, 8 months later they came back to me wanting to know more about this mystery box. I still laugh to this day about that product launch, 2 years later and $2.5 million behind budget. Glad we were able to get it launched though.

Wow! Finally have data to put this battery into perspective. For comparison there are two worlds I will be comparing this battery to the Lithium Coin Cell, those two worlds are “stand alone”, and “2nd stage back up power”. Stand alone has no other power than the coin cell itself. 2nd stage back up power offers power to the circuit when main power is shut down.
Lithium = ~3.2v
G+Al = ~2.7v
G+Al Battery, 2nd stage back up power and is only that, if even “considered” that. The “considered” part is due to circuit design, when the engineer is designing the circuit they design around an unwritten rule in the industry standard and that standard is around ~3.0v. Now….pending the Chip selected to handle the memory and RTC save off when power outage happens, most processes get down to ~0.8v(some, just using an average), before the battery can no longer save off to the internal memory.
“Graphene in Aluminium Ion Battery at ambient temperature cycling from 2.7V to 0.5V, 4.5 Coulomb (2.2A/g) charge rate.”
This bit of information really limits the G+Al battery for a lot of design considerations, because like I said engineers are looking for the “3.0v”. Even ifffffffff they know of this battery there are changes to the circuit design and even Firmware(I know a lot of people will say, “those are not big changes”, yeah you are right not big changes, but when the product line has been developed for 15 years on that 3.0v platform, that becomes a big change). I digress, so like I was saying. In design that CUTOFF voltage is huge, and by the looks of G+Al battery characteristics taking it to the 0.5v Cutoff will make this a win. They have to sell this to Computer Manufactures that is the only sector(there maybe other sectors that could benefit from this battery), that I see it could really benefit from this tech.
Stand Alone use, the G+Al battery is a complete waste of time and money. Given that most designs around stand alone devices design around ~2.0v to ~1.8v and if you look at the battery drain characteristics you will notice that it is around 150mAh/g, and Lithium coin cell(2032) is around 215mAh, and the lithium used in a 2032 coin cell is ~0.1grams(that’s insane, if you understand the power to weight ratio(energy density)).
Once again the Unwritten Rule in Design is 3.0v so they(GMGMF) misses out again on selection.
Hope this is easy to understand, if they market this baby right( and that is not my area of expertise) they could stand to win and put more money in to future development which would really help.

IMO there are plenty of really great batteries and battery technologies........on paper. If we were able to do what math and models say is possible we would have portable electric everything with batteries that are light, incredibly power dense and charge instantly. The problem with these fantastic batteries and technologies is that they are not real, they are models, they are theory, they are scientifically possible but totally impractical for one reason or another. For me, I need to see something more than an estimated ("industry standard estimate methodology") spec on a piece of paper, I need a battery that can be tested real world and built in mass. The whole market is on a fire sale $LAC will be just fine. Did you ever find a way to get into Sayona? Good things coming!
