Just to add some context as I'm a shareholder in GMG, their batteries are 100% recyclable and hold the same energy density as LFP batteries, in fact once you deduct the weight of the thermal management system and the energy it uses for NMC batteries, it's almost a wash. The theoretical power density is also twice that of Li-ion and they are much less toxic and not nearly as prone to overheating as Li-ion. Love hearing coverage on these guys, great info!

I've been making my own graphene for the last year and have gotten my process down to about $10 US per liter (done in much larger batches of course). It's not difficult in the process, rather it's time consuming on a low/medium scale, however it would easily ramp up to industrial size operations with larger equipment. I wasn't happy with using off-the-shelf graphite as that's a major cost if you intend to do it that way, so you might say my version falls into the synthetic variety. On the plus side, it's far, Far easier to get higher quality and pristine alignment rather cheaply in the conversion process. I'm constantly evolving and refining the techniques, and just yesterday I stumbled into a better use of the byproducts to turn some of the chemicals involved into soil-buffing fertilizer and am now wondering with yet another tweak, recapturing even more to use directly as electrolyte. I've got a lot on my plate for application testing in the next year, as initially I got into this to make 3D printing resin substantially stronger and less brittle, but the ever-growing list blows my mind into what all can benefit from relatively small additions of graphene.

Hi Ricky, love the show and informative as always. There are, however, a few things missed about the potential of GMG's battery. One is the thermal dissipation - due to the graphene and aluminum construction, thermal energy is easily removed from the battery and thus requires less cooling. This would result in a massive reduction in the need for additional cooling equipment for the battery pack that adds to the overall weight. herefore more batteries could be packed in the space used and thus increasing the battery packs overall energy density. Another is the increased potential of energy recovery through breaking. Current tech is limited due to the batteries inability to handle the full charge when utilizing the motor to slow the vehicle. With GMG's battery more energy could be recovered this way, which further increases the range from a single charge in under 5 minutes. Exciting stuff right? Keep up the amazing work bro and look forward to the next one. 🙃

Think of the battery for small projects (cars are the biggest today). Hydrogen will be used for big stuff likes commercial airplanes.

I still think one of the most important things that needs to be done to improve the power grid and dramatically reduce the need to coal is to put batteries in the house. At that point, the size and weight is less relevant. Putting batteries in the house reduces a lot of the stressors on the power grid, helps to handle power outages (storms, fallen trees, accidents, etc.) and greatly reduces the need for Peaker Plants as well as non-consistent power sources. As much as I love electric cars, fixing the power grid and the mega-pollution behind it is a far more important use of batteries in my opinion. Creating batteries with much greater power storage (not density) and much smaller environmental impacts to me is the number one priority. By doing this, improving our electric infrastructure, the survivability of the grid, and more importantly for electric cars, charging during long term power outages, we also greatly increase the infrastructure needed to support all electric vehicles and drive down the cost of that support.

Reduce the need for photo-electricity production at the home, replace it with heat to electricity, and all the photo-e generated can go into charging a car (or other mobile things). It's a large issue.

Large-scale graphene manufacturing where it is in intended large area sheets of a given size (especially larger than a few microns) has thus far been similar to fusion reactor duration for energy generation: always years off. I’ve paid attention to graphene for iirc the last 20 years or so, and it’s still so valuable and yet, for its desired effective purpose that larger regular sheets are required, much like gold: nice to think about, but expensive as hell, and actually more expensive than gold. As to the energy density and recharge times, it’d make sense for short-hop commuter cars, but long distance travel would be worthless. Generally in the eastern United States there’s never very far to go to other cities and utilities. In the US west you can go vast distances without seeing proof of human habitation except perhaps the road you’re driving on, and you can go easily 75 miles non-stop with zero cell signal or even see a place where a cell tower is at all. Such a short-range car would likely leave too many people stranded as a result.

@@chrisbraid2907 Solar panels aren't efficient enough to charge an EV with any relevant range in a couple of hours. At best, current mass produced, affordable panels (not satellites, etc) are only 24% efficient at best & you'd have to have a few at 250 watts output! How far will you get with 2kWh?

Accessability is the biggest challenge for EVs. As polluting as fossil fuel cars are being able to just pull in to a tank, refill, and be on your way is infinetely more practical than having to recharge over night. Being able to recharge your battery in a couple of minutes would be such a gamechanger in accessability and getting people to actually use the technology.

There is another elephant in the room with rapid changing, particularly if a full charge is expected to take place in minutes. That is ability of the power generation and delivery network to supply that amount of energy. To supply that amount of energy in a few minutes is going to take some hefty infrastructure. What would it be like on a forcourt during rush hour with charhers pulling somewhere in a region of 1000A or more each. Our power generation and utility networks are currently just not designed to do this. There will have to be masive investment in provision and delivery first.

Very well informed information. Thank you JC

Thank you for another great, informative video. Graphene is the only sensible way foward from batteries to screens and even cables, fancy having near zero resistance power transmission lines? If we could crack that production problem we would leap forward another 20 years in capabilities so no more videos, get cracking and solve it, you have tha name for it!!

Charging a car that fast brings some challenges other than battery itself. Those can be solved for sure but they are not insignificant. Having a fast charger that can deliver maybe even a megawatt of power for a few minutes to probably several cars simultaneously needs some pretty serious grid connection, big intermittent load on the grid etc. Probably better for the charger to have its own large stationary battery. Then you need to have a cable and a connector that any untrained person can handle and it can deliver that much power. How to make it light enough and yet keep it cool enough? Maybe even higher voltage than the 800V some EVs already use? It will be interesting to see.

Yes. Charging 10 of Elon's finest Tartan in 600 seconds is enough power for a TGV at full tilt. Maybe swapping will come back. I'd like to see some Le Mans 24 hour streamliner racing with tyres and batts switched in seconds.

As an owner of an EV I don't care at all about charging time(ignoring extremes). All of my charging has been at home when I wouldn't be using the car anyway. I generally drive 30-40 miles a day and that's about it. While faster charging is cool I basically only care about energy density. The few times I've had to drive 200+ miles in a day it's been nice to get home plug it in and not worry about going to the "gas station." Like if we get to the point of 500 miles in a car with the car weighing less than it currently does I think that's the dream. Then if you need more than 500 you just get that option.

Thanks for this. I look forward to seeing these developments come to fruition.

When, there are numerous battery tech out there that are game changers. Fact is it will be 10-20 years before any come to market.

Very well done. Thank you for the excellent presentation.

Graphene on stacked copper foil would increase wire conductivity making motors more energy efficient and lighter weight. Graphene between thin glass would increase strength and would be a conductive layer of both heat and electricity.

I like the idea, it's just all these new battery types seem to never make it to market because every other day someone comes up with another better battery. We are going nowhere.

Thank you for what you do (From San Diego)

I believe in graphene as the future for EVs. That is why I am investing in graphene "start up" companies.

The only constant in this old world, is Change! Laissez les bons temps rouler!

graphene is my absolute favorite battery. 1000 watt hours per kilogram of weight, compared to lithium at around 250 watt hours per kilowatt. rumble motors offers a graphene battery choice/option/upgrade on the ebikes they sell, and the buyer just pays the difference for the better graphene battery.

Really good explanation! Thank you!

Thank you. I am so close to converting my RV to lithium batter system but cost has been an issue. So since I can wait, I shall and see where graphene takes us. Thank you again for your videos and insight.

This can be a big deal all around. Cheaper, more energy dense, high charge-discharge rate. But for use in a vehicle there is one overriding problem: Power. You know, the product of energy and time. For example, take a battery sized to 400 V at 100 KW hour . Neglecting losses in the processes that means it should be able to charge/discharge at 250 amps. Over an hour. We ARE talking KW hours here. If you want to charge in half that time you need 500 amps. But that is a 200 KW rate. Still ok. Now try this in only 10 minutes. That's 6 times the current, 1500 amps and 400V. A 600 KW power substation better be nearby. For charging one car? Not to mention the amount of copper required for this current. And don't forget the connectors. You think the price of copper is bad now? Hah! I know, double the voltage and you will halve the current. It's still 600 KW of energy. Not something I want to be around if there is a fault. Anyone charge in the rain? But, I think the tech is great. An excellent reason to build more nuclear plants.

You missed the huge elephant in the room with recharge, the grid. It's all very well charging one or two vehicle's at this high speed or even overnight on the grid but multiply this by 10, 100 or 1000 times and the cabling required is huge, also the other limiting factor we are seeing here in the UK is substation capacity. None of our current infrastructure has the capability to charge these batteries at any scale, it just wasn't factored in when it was deployed.

Graphene might be good for power transmission lines.

Every time a loud screaming pet commercial comes on a cat gets its wings. You did that. LoL

The problem with a 6c or 10c battery is the amount of power being transferred. The cables required would be huge. If say 10 cars with 100kw batteries shows up at the charging station you are looking at a megawatt being pulled from a small local portion of the grid. The demand charges that the utility company hits the charging station is going to be huge.

You always give great new technologies, how they will change the world then, near the end of the video you do a rug pull. But I still live the first 75% of your videos.

The biggest challenge is always to setup the factories to start producing these products at the quantities required... Li-Ion is well established, the dangers are well known, etc. There are many battery discoveries that have been made in recent years that are promising to be much better, denser, faster charging and cleaner than Li-Ion batteries... NONE of which have seen any significant production levels yet!!! But yea. I hope something better than Li-Ion comes to light pretty soon. Because we don't all need to travel 200km+ to work and back each day... Meaning 200km of charge in a cheap, light EV for the day would be plenty for most people, including me.

Great video. We have heard about it for years though, hopefully it will soon come to market. 1C 1 hour is 10min at 6C.

Thanks for the video, very well described all the amazing properties of graphene for batteries! Unfortunately I don't see any sign that we are coming closer to a commercial use. And its energy density it's a huge handicap....

What is the life experience? Duty cycle, how many charges? Affects if introduced to water? Can it be completely depleted then recharge/does this affect life length of duty or usage? Does extreme heat or cold affect its performance? Cost to replace if damaged?

Difference is that as charging infrastructure expands, the range anxiety of such a battery would also become void too. You can’t just build a gas station anywhere, since humanity’s nitpicky, but you can build a charger anywhere. To the point that it wouldn’t even be too ugly to make stations at National/State/Provincial Parks. And if you can make infrastructure to fuel a car there of all places, and have nobody think poorly of it; you can do it anywhere.

I like that there seems to be a timeline to when we might see these in production. Past graphene news was always in the nebulous "soon" future.

I wonder what a graphene battery would do for power tools. I'm old enough to remember cords on the construction job site, we'd fling them around and be happy about not using damn hand drills. Then the battery tools came out, crappy at first. Now nobody uses cords. Haha

By the time your batteries are widely deployed it will cost more to re-charge an EV at a public charging station than it costs to fill your tank with gas. The fast charge itself is a massive energy dump off the grid into your battery pack so it puts an even higher load on a system that is not designed to re-charge a national fleet of electric vehicles. The entire grid infrastructure will have to be over built from generation to transmission, distribution sub stations, lines, transformers, poles, charging station drops. At the same time they also have to build all new generation to replace the coal and gas generating plants being permanently shuttered across the country. Electricity cost is going to double or more.

I have been studying electrical theory for years now and one of the most fascinating things I have found out is that batteries don't store energy , rather they supply the electrical tension to a circuit that pushes the charge around the loop . Think of a refrigerator in that the compressor doesn't pump energy thru the freon lines rather the energy in the form of heat inside of the refrigerator flows into the the freon 90 degrees to the flow of freon . It's the same thing with an electrical circuit in that energy from the local enviroment flows into the load 90 degrees to the direction of flow of charge .
