Battery 4.0: The Solid State Battery Revolution

I have an old (early 50's) Transatlantic Radio. The battery is rechargeable weighs in at a bit over 6lbs. and can output 9v or 90v. It's a dry zinc-carbon pile and it still holds a charge. Not exactly state of the art but then I doubt anything made today will hold a charge after 70+ years.

[@YouCountSheep]

Its funny how some of these technologies come back. Idk why were were chasing liquid applications for batteries anyways, solid is much denser as a material anyways and thus can hold higher charge. But I guess planned obsolescence also played a role with companies seeing the battery as a timer to sell new stuff. Same with thermal storage. Now "sand" storage is the new hot thing. We have known for centuries that stone has insane thermal mass, yet you never hear about stuff like that. Or insulators for that matter, everyone wants to make a new insulator while we already know the best type of insulation, which is having nothing, literally. Vacuum that is, but it isn't applied at a large scale, we still use materials that trap air in bubbles as thermal insulators which is stupid. Could as well make even plastic structural panels which can hold up against atmospheric pressure and it would be perfect insulation. But nooo.

[@oleksiyprotas6376]

You're getting it wrong about 80% - For slow charging it's the default charging target because staying for a long time at high SoC makes the battery degrade relatively faster, so there's an incentive to slow charge to 100% only it you really need it (not applicable to LFP and some other types of battery) - For fast charge the safe charging power is gradually reduced as the SoC grows and then at one point transitions from CC to CV saturation charge phase where the current naturally is rapidly falling even if there was no safety limit in place. You can absolutely charge to 100% on a fast charger, it's just that the tail % usually take so much longer it's not worth it. Yet there's no damage in doing so.

[@itranscendencei7964]

This is actually super exciting, especially in combination with the upcoming solid state cooling. I'm imagining laptops, handheld PC's, and other small form factor devices that have not only cooling potential that is much greater, quieter, and smaller, but also lasts days at a time on a single charge while only taking 10-30minutes to fully charge. The future of hardware technology is definitely bright.

[@Mat_1000]

To me, the real question is, if solid state batteries require more Lithium and that we already are on a tendency of Lithium shortage, where are we going to find all the Lithium needed for all the appliances it's supposed to cover (EVs, handheld devices, home appliances etc..) ? And at what cost for the planet ? The theory maybe makes the future looks bright, the reality of how those materials are found and extracted from earth look scarier (To produce cheap solid state batteries, it means we strongly underpay someone somewhere that is going to get his/her hands dirty to go get it for big companies, so do we keep on exploiting misery around the world? Also, when a resource is limited and that many countries want and need that resource, what happens next? ).

Solid state may take a while to get up to mass production at a competitive price. But I think they may get early use in packs with more than one type of battery. Might allow for very fast charging up to a percentage.

[@enlightendbel]

I'm wondering if the spinup of a lot of grid storage megaprojects coming up may aid in streamlining production and bringing down cost. Getting 3x the storage out of a grid buffer system and having it be more versatile in how fast it recharges and unloads energy is going to be hella attractive for grids. Especially with how sporadicly surgy solar and wind can be. Classic power plants tend to have a preset X amount of energy output that doesn't vary much from what you set it for. This while both solar and wind are very surgy dependent on the current wind or overcast conditions. A solid state battery system that is able to charge much faster is a far better buffer system for modern renewable energy storage than gen 3 is.

@@32BitJunkie Yes: some of us -- many of us! -- have to stop to pee well before the EV is below 20% state of charge. So a stop every couple of hours is necessary for reasons other than charging up the EV. Put another way: pee interval < recharge interval.

[@randomnobody660]

@@xchopp Yeah but how long do you stop for thou? My family might just be more allergic to movement than usual but in my experience ~850ish km trips typically only necessitate 1-2 stops (depending on who's awake) of ~5ish minutes max. Bathroom + quick stretch doesn't take that long so typically fueling speed is already a bottleneck. Google says the average EV has a bit under 400km range in 2019; let's say it's 500km now. If you are doing 20% to 80% to maximize charging speed that cuts that to 300, not accounting for lowered range on highways. That's a break every ~2.5 hour for ~30 minutes rather than every ~5 hours for ~5 minutes. That's significant. Now granted long trips are once or twice every few years kind of thing, so you could argue it's good enough most of the time. However by the same token you probably don't need a car period most of the time. Now I think about it, maybe gas powered crew cab pickup per household for the long trips and moving sofas/pianos/TVs and an e-bike or moped per person for everyday mobility is likely the way to go. Much better for the environment too.

[@randomnobody660]

No, they are limited, and sometimes more than by 20% too. Typically there's both a top and bottom SOC (state of charge, not at all confusingly sharing an acronym with system on chip) buffer to prolong battery life. On the tesla model 3 for example the top buffer is apparently 10%. So when your cars displays 100%, the physical battery cells are averaging 90%. Didn't find anybody talking about the size of the bottom buffer, but apparently it's typically larger than the top buffer. When people recommend using 20% to 80% of an ev's battery, that's on top of the built in buffers. So charge rate actually drops of a cliff at more like 70%.

Even if the cycle life is low, if they can be made inexpensively enough and there’s a “core fee” for returning the used battery (which it would because the mineral ps in it would be worth a lot of money when recycled into new batteries), the car manufacturers can quite easily make them quickly changeable. The Chevy Bolt battery takes about 2 hours to replace, and it wasn’t designed specifically to be quickly replaceable. The catch is that the cost difference between the new and used battery + labour to change it has to make it economical. A 300 cycle battery that can go 500 km per charge means 150000 km of use before needing to be changed, which is about when a lot of cars would be scrapped. Even changing at 100,000 km would quite possibly be economically viable.

Cycle life is directly tied to dendroid formation, so if we are to believe that the glass-like plating barrier can overcome a large portion of this, then cycle life naturally will increase by default.

Maybe, but bcause you could in theory fit more of them in - you can also cycle between the pack's module cells meaning not all them will be hit at once all the time per charging. aka longer life if you dont fully charge up every time. Also, a cycle is a bit misleading - its more on how quickly can a dendroid form and normally thats because of heat... so if they can stay cooler per charging - that could result in a longer life as well.

OTOH, if they're reliable enough to be treated like giant capacitors, maybe we can just leave our cars plugged in to assist with power requirements during peak load times, and charge when the load is low, and get a credit from one's power management company.

The problem is that existing cell chemistry has higher resistance and can't sustain those charge rates much beyond around 40% SOC and start to taper down the power as the pack fills up. A solid state cell supposedly would not need to taper the same way and could take the full charge rate until closer to fully charged. That means a realistic 10%-90% charge could happen in 10 minutes or less with existing chargers.

@@JRP3 Well, true, I am an EV owner, but if I already knew, I wouldn't need to ask. ("No such thing as a stupid question," right? Or have I yet again achieved the impossible?) I did know that charging slowed as the battery charged, I didn't know the slowdown was that significant. Also, it seems my attempt at brevity has resulted in a loss of clarity. If you consider it important enough to impugn my asking, then you are already aware that the ZEO Leaf didn't (and "couldn't") have L3 charging from the factory, and the reason I have experience with it is because I bought the floor model wherein Nissan had installed CHaDeMo during MV so sellers could brag about 30-minute charging in the showroom (even if they couldn't sell the $700 feature until late 2012.) I also know (by asking the battery engineers at work) that DC charging incurs an overall SOH penalty, and so I have only done so 153 times over the life of my current battery (at least once a year for therapeutic reasons; the higher voltage allegedly breaks the little dendrites that form when charging, the ones described in the video at 6:45.) So far, it seems to have been highly effective; while my original battery had dropped under 70% SOH four years after we bought the car, the replacement battery (special thanks to Mr. Klee and his class action versus Nissan) is eight years old, and has just recently dropped under 70% SOH, meaning it took twice as long to do so. *Thus my interest* in the effects of *repeated fast charging*. Do SS batteries suffer negative effects from fast charging as well? I suspect I will have to wait and see, though with a bit of luck, some enterprising soul will engineer a way to swap out the cell packs of my puny 24kWh battery with SS modules. With any luck, they'll last longer, charge faster, cost less, and be readily available. Also, because I think we are all in this together, I'm interested in learning what I can about it because if my car battery be a power sink for high-demand times, and auto-charge at low-demand, I'll make a point of getting a home charger that will integrate with such a system. It might even prove to be a profit centre for me. At this point, it may all be vaporware, but I ask because I'm trying to be in the know in advance of when the time that I will need to act.

But yes supposedly the SS battery chemistry will not have negative effects from fast charging, though already newer existing chemistries have little issue with it. A company called Tesloop ran a Model X shuttle service only using Superchargers and had vehicles go over 300,000 miles on the original batteries. The issue with the old Nissan packs is lack of active temperature control as I recall, all other vehicles us active liquid temperature control for batteries. Also your DC charging sessions don't use "higher voltage" since that would overcharge and damage the cells, it uses higher current, (amps). Your better capacity retention could be the result of improved cell chemistry.

@@JxcksonSF Yes, but that would entail there to be an actual update to begin with. What was told here is not news, it's merely a report on things that have already been in the works for 5+ years. It's not like a breakthrough was made recently - at least not a significant one, just a lot of small steps. I don't agree with OP's point that it should not be reported on, but at the same time it also shouldn't be sensationalized until there is something actually sensational to report on. For now, it's still deep in the r&d phase, and we are still waiting on the same milestone of breaking into grid scale production and actual field implementation rather than lab monitoring. As someone who does follow solid state battery development quite closely, I really don't see what the news worthy content was for this video. Basically can be summarized with "Toyota wants to use solid state batteries, hope to be closer to production in 2026", and that's about it. Nothing else was new nor ground breaking. It's more or less the same issues that were being tackled 5 years ago, we are just a little further along, but not to any degree where we can actually say when this technology will be implemented in actual products for consumer/enterprise. There are a lot of battery advances like it, but they're all still in lab and wishful speculation will never be news worthy. Oakridge Uni is developing tech that rivals solid state, and they hope to have it ready for field testing in 2025 - emphasis on "hope". That's all this is, for now. And personally, I don't find "hope" to be news report worthy.

They never said you can't charge to 100, they just said that it has diminishing returns past 80 and that's why 80 is the standard for charge time reporting in general, and this is what can now change.

Every big automaker has recently agreed to adopt the Tesla charge port standard, meaning everyone will now benefit from a unified grid going forward, rather than the separated systems that have been used up until now. Sure there is plenty of room to improve, but this is a major step in the right direction. Besides, the more normal electric vehicles become, the more companies will adopt charge-from-home systems and thus lower cost on those systems, meaning most people especially in suburbs are more likely to not charge during their daily commutes at all. It's mostly in the big urban districts/city centers where such methods are limited. I'd hope the US looks to Scandinavian countries to see how this problem is already mostly solved there, with public chargers available at pretty much all parking lots, and businesses actively encourage electric vehicle use by offering their own charging solutions for their employees and customers. These countries are already 5 years ahead on the electric grid front in urban districts. Adopting their solutions should be quite straight forward, they already proved how to efficiently solve the main problems.

That means for your 10 minute charge time, you're pumping 300kW into your car continuously. 300kw is the absolute maximum electrical capacity of 14 good sized suburban American homes. Let's say you have 10 chargers at a station - you'd need the electrical capacity of 140 houses for that one station. I haven't even talked about the fact that the cables would need to weigh over 120 lbs PER FOOT to safely carry that kind of power at EV charging voltages.
