New 2022 graphene battery launch : 8 minute charge time. 350 mile range!

Having worked as a researcher in nano electronics, this sort of thing was always the stuff of dreams.it is great to see industry now taking scientists more seriously to get the things we need done. We should encourage and strive for leaps ahead rather than modest improvements as we really lack the time.

[@farmergiles1065]

Searching for improvements, modest or otherwise, is always a good thing to do - as long as it's not the only thing you do. We also need to search out new ideas, new methods, and work where there is a solid promise of breakthroughs. Leaps ahead are usually the result of a lucky discovery that was unanticipated. Except that I don't really believe in luck. If you're doing solid work, exploring the unknown always takes you into caves and over cliffs, but it also tends to produce that luck that gets you where you never knew you wanted to be. Incremental improvement research makes for more predictable progress, but it doesn't get you the big bang. You need both. It really doesn't matter if we "lack the time". Good work takes the time it takes, and discoveries come when they will, needed or not. All we have control over is doing the work. Needless to say, you also want to work as smart as you know how.

I started out as a computer engineer in 1970, before integrated circuits were ubiquitous, in 1960 hobby magazines were still describing projects using valves (tubes) and generally you had a choice of four transistors for your more modern projects: OC44 & OC45 for RF and OC71 & OC72 for AF. If you were skint you bought red-spot transistors. IIRC In 1960 a transistor cost 10/- , £16 in todays money. I've just bought a stabilised variable power supply from Amazon for £17 For me the biggest advance has been in the reduction in size of various devices, when I started in 1970 hard disk drives holding 80Mb were the size of a small washing machine and ran off 3 phase mains. You had to allow 28 days for delivery on anything you bought mail order. I ordered that power supply at 21:00 yesterday (Saturday) and it was here today at lunchtime.

It'd be interesting to compare the differences these alternative anode topologies make on batteries of different cathode chemistries. There's Nickel-Manganese-Cobalt (NMC-333 or -111, -433, -523, -712, or -811), Nickel-Cobalt-Aluminum (NCA), Lithium-Iron-Phosphate (LiFePO4), and all of the other ones like Lithium-Sulfur. Most electrified public transit fleets use LiFePO4, so I wonder what increased anode volumetric battery density could do for those since this cathode type doesn't store as much as NMC - which you find in most consumer EVs. Could decrease costs even more and allow for more onboard battery capacity, meaning greater travel distance, better grid demand response during bus downtime, and maybe even smaller fleet sizes if recharging/switching out buses isn't as much of an issue. It looks like this tech is mostly aiming towards the consumer vehicle market though, given the focus on charge times, but this is still a worry for a lot of ICE users. Reducing charge time will indeed lower the barriers to entry and better persuade portions of the population to make the switch. I'm still betting most of my money on better public transit and rail, but climate change won't wait for society's best wishes. A silver buckshot of a tapestry of solutions is best

[@paulskaar8556]

Along those lines, I'd like to see a broad peek at tech with the most abundant materials (e.g., carbon, silicone, iron, calcium, aluminum) vs. tech that relies on precious/rare/hazardous substance (lithium, silver, cobalt, platinum, rubidium). I'd expect the former to be making headway on a route to dominance since cost, including life cycle and environmental costs, will IMHO ultimately decide the winner(s).

[@alphaxfang]

like anything in research world, any breakthrough technology doesn't guarantee it will be the best technology for the masses... it can be stuck with high producing cost, supply issue, can't be scaled up, hit the development limit, etc... letting the market sort it out means at the very least the product already have the capability to scale up... for the rest of the factor only time will tell if that technology hit the jackpot or not...

The market is often the most efficient way to discover the "right choices." Not always, but very often markets do that more efficiently than central planners. It is impossible for a central planner to know all of the information of every market participant. Therefore the central planner can't set prices as efficiently as all of the people in the market, which means the central planner can't allocate resources as efficiently as a market.

The funny thing is that the only people who care about EV charging speed is those who don't drive EVs. Once you try it, you realize that this obsession with charging speed is silly. In practice it's rarely a concern. Same with range. 300-400 miles of EPA range is plenty enough, and a lot of EVs can do that now. The real challenge now is cost and scaling. We need to replace all gas cars, and that won't happen with $60K Teslas, nor at 1M per year production capacity. We need $20K cars and 100M a year of them. Fortunately scaling up production also lowers the cost, so the main concern is scale. And the limiting factor is mining the special materials that batteries need. So the focus of research should be using more abundant materials, and better mining techniques. On good example of that is the LFP chemistry. It has worse energy density than the traditional NMC and NCA chemistries, but it uses more abundant materials, and a lot cheaper as a consequence.

[@nekoJens]

It is tempting to see the future as an extension of the past, e. G. to do with EVs the exactly the same thing as with ICE, but it does not have to be that way. So the scale of the problem may be far less daunting. 1. With more car sharing services coming up, ownership rates could drop by over 90%, studies have shown a shared car can replace 18 owned cars. Which is a far better use of capital, since a personally owned car is only driven very little and parked 90-95% of the time. Ownership is actually far more expensive than people assume, like 200k$ over 20 years on average, taken together everything. 2. For cities automotive transport is highly inefficient in its number of people moved, land use, congestion, accidents, infrastructure cost etc... So obvious solutions like well developed public transport and bicycle lanes could reduce the required amount of cars even more... Meaning the actual number of electric cars needed could be a tiny fraction of the number of current ICE cars.

[@robinherrick2177]

The charging speed determines the infrastructure. At the moment, it can barely cope with the tiny number of EVs on the road. 100% EVs will be chaos but with a fast charge we could keep our existing "filling station" approach.

Inductive charging is probably a no-no environmentally! Even at a 80-90% efficiency (for the wireless bit, not for the rest of the system), that will probably add 20% to the electricity power requirements at peak road congestion times rather than buffering when energy is available from the grid.

In the mid-1980's, I worked for a contract engineering company. Their specialty was evaluating emerging technology. Toyota asked us to look at a "Paper Only System." Solar panels worked during the day to charge a battery pack in the garage which, at night, would recharge the car. We told Toyota that the practical implementation would be 35 to 50 years. I guess we were not too far off the mark.

Glad you like them! I'm doing a 1 year review of Gravitricity and Energy Vault (tower of babel) in a couple of weeks times :-)

[@matthewtalbot-paine7977]

I think inductive charging is unlikely. The distance you can get on such things is very low and also roads get repaired quite a lot meaning you'd have to dig up the coils and replace them every time you do so so unless a new type of road is coming then that seems unlikely. Battery swapping seems more likely to me although that will require cars to be outfitted with swappable batteries. My favourite idea if it is possible is overhead power that cars and lorries connect to but while I've seen that work with lorries because obviously it has to be a little bit higher than the tallest lorry it's going to take a much longer attachment to charge a car and it seems like it would be too long to be stable at motorway speeds anyway. Maybe you could have a special car only lane for this.

[@philiphtube]

It's all very well having a battery that can charge really quickly but you still have to pump all the energy into it somehow. So to recharging a battery really quickly will require enormous current and hence the cabling involved will have to be really substantial. It will also mean that the supply to the charging station will need to be adequate as well. I don't know how that is going to work with an electrical supply system that's built around residential households using a maximum of 60 amps peak. There's also going to be a fair bit of heat generated in all the cabling involved.

There is existing tech for making, storing, transporting, and using H2 with some ease. New catalysts make making H2 easier and cheaper and more efficient, making ammonia for transport using new catalysts (this is more volume-efficient than liquid H2 and doesn't need to be cryogenic and can use existing mature transport methods), a new catalyst for reforming ammonia to H2 at the user's end. All developed by CSIRO, and in combination make H2 infrastructure entirely possible and cost-effective.

I honestly thing the current rapid charge speeds( ~25ish minutes for 10-80%) are fine. But It'd be amazing to see these improve the already good lifespan of batteries to something great. Kinda like how new oled tvs are being improved just by lamenting a better cooling solution to the stack. Which leads to lower operating temps and less degradation/burn-in. Less battery degradation means you can go with that lower capacity model saving money and environmental cost without loosing much range in 5-10 years. Also need the kw/mile efficiency to improve and for car makers to stop putting gearboxes in EVs.

[@paulmichaelfreedman8334]

Same applies to solar panels. Hardly ever is cooling installed while on hot sunny days the efficiency decreases by up to 50% due to the temperature of the panels, they get burning hot by the radiation that is not converted to electricity. With a simple cooling solution you can get double the power out of your solar panels!

[@steve6375]

Charging stations are currently badly designed. They can only charge one car in one space and you have to wait for the car to be moved afterwards. As charging times decrease, we will need one charger shared over say 6 parking spaces connected by 6 cables all at the same time. The charger will cycle round, charging each car in order of their connection time, automatically read the cars ID required charge and charge rate and deduct $ from its account whilst the owners get a coffee, etc. The top of each charger will show the estimated waiting time for each charger so on arrival you can choose an empty charge space which shows the shortest waiting time if you are in a hurry. Encouraging people to spend whilst taking a charge break will be big business.

@@LunarLaker Good point. I think low-grade graphene (aka platelet grade) is suitable for anode applications because it is just a few layers thick. This is not costly to make using graphite exfoliation. This grade of graphene is also useful as a structural additive in composites. High-grade graphene (1-2 layers) is produced differently, using CVD (chemical vapor deposition), and is more costly but still doable. I’d love to see a more detailed video about these issues.

I love these video's of yours. The channel "the limiting factor" did a video this week about Sodium-Ion batteries And why it will always take between several to 10 years to scale up production of a new type of battery. It was very interesting, but the takeaway was that it usually takes about a decade because not only does the scaling up of the production of the new technology need to be scaled up from lab to pilot to full production in 1 location, to production in multiple locations. Look at tesla, it took them more than a decade, and even they have trouble with scaling up their latest form factor. Another important complicating factor is that the supply of resources for this new chemistry needs to scale up, with its own bottlenecks and problems. I recommend you to watch this video from "the limiting factor. it goes into much more detail. In short, I don't think it is likely these new batteries will be in a significant percentage of cars within 10 years.

This is only true if you want to make money by restricting knowledge (secrets) or its application (patents).

Special high-output chargers will be needed. Not just for this car, but in general. The majority of current public chargers are _not_ capable of delivering several hundred amps/kilowatts. And the electrical grid will need to be massively upgraded. It currently struggles under the higher demand caused by increasing AC use as summer days get hotter. Adding thousands of electric cars (in just one "region") simultaneously drawing 100kW - 500kW each (just guessing at future needs) will blow up the current system.

@@LizardVideoDude EVs also stabilize grid systems by mopping up excess energy in the grid, reducing baseload power stations and stand-by power generation. Excess wind and solar power, plus return-to-grid stabilization. EVs don't typically need to charge at any given set time, especially since the actual use is 1/30th of the day, typically, so can be used for grid balancing. "Smart grid" efficiency may be more important than size. I think your concerns will be more for long trips and vacation travellers, freight transport. Either way, yes, the electric grid was built when there were 2 Billion people on planet Earth. It's not designed to handle 9 Billion people.
