Huge if this pans out.

GMG claims that the batteries they are producing can charge up to 60 times faster than the best lithium-ion alternatives currently available. This means that, for example, an Apple iPhone could be charged in as little as ten seconds.
GMG’s graphene aluminum-ion batteries can also hold three times as much energy as other aluminum-based battery cells. Peer-reviewed testing has demonstrated performance of 149 mAh g-1 at 5 A g-1 in the new battery, improving on every aluminum-based battery produced to date.
GMG says that the battery is the most reliable, strongest, and fastest charging graphene aluminum-ion battery currently in development.
quote:
The new batteries from GMG are composed of aluminum foil, aluminum chloride, ionic liquid, and urea. The benefit of these materials over lithium is their stability. This makes for a safer battery, with faster charging time and denser energy storage capacity.
Aluminum-ion batteries charge faster than their lithium-ion counterparts. This is because they exchange three electrons per ion when recharging and returning to the negative electrode in the battery. Lithium-ions can only move one at a time through the battery in recharging.
Aluminum-ions also have no upper Ampere limit, which means they do not spontaneously overheat and do not require extra cooling to function safely. In contrast, lithium-ion battery packs in EVs are made up of around 20% cooling components.
Adding to the safety factor, aluminum is non-toxic – even when digested by human bodies.
Unlike lithium, aluminum is a readily available resource. This means that aluminum-ion batteries do not pose the same rare earth metal problems for mining that lithium-ion batteries do.
Aluminum is also one of the most recyclable materials on the planet, further improving the sustainability of aluminum-ion batteries in comparison to lithium-ion cells.
Significantly, aluminum is much cheaper than lithium. In 2005, lithium cost around $1,460 per ton. This has since risen dramatically to $13,000 per ton. At the same time, aluminum’s price merely rose from $1,730 to $2,078 per ton.

They may just be taking the piss.

This board has informed me that EV's are a fad and not going to take hold long term

$2.14 USD per share. Hmmm.

I'll believe it when I see it. With that said, I'm pulling for them. I've said for years that we are going to kind of stagnate on technology a bit until we significantly improve battery tech.

False. You’ve never been informed.

This right here ensures that China will pay off more of our “elected” leaders to make sure this is never adopted in this country.

Maybe, but the Australian government is financially supporting the research.

graphene
Graphene is a single layer of Carbon atoms.
Unless things have changed from my days doing electro-chemistry Graphene is expensive as frick.
Like over $100/gram.
Hate to be "that guy" but if you ignore cost lots of solar/battery tech etc can be very efficient.
Just stack thin layers etc.

Exactly why our government shouldn’t have to. Let private companies take the risks, collect the profits.

At least during the skimming that I've read, supposedly the breakthrough is in the ability to pack more aluminum within the graphene thus increasing the density. This allows the faster charge and increase in storage and not needing as much graphene. With that said, seems the down side is the weight which is 3-5x that of lithium. So would be interesting to see how that would affect the performance in electric vehicle applications.
Of course, this my skimming and everything I read could be wrong. I'm always skeptical on these breakthrough technology advances
