I grew up in the era where NiCd and lead acid batteries where the only rechargeable batteries of any significance available. People thought at the time that it was going to be nearly impossible to improve upon those designs by any significant amounts yet here we are with batteries that are many orders of magnitude superior to those early versions. I'm confident that it won't be very long at all until the batteries used in EV's will be at least an order of magnitude better than what we have now.

[@jeffsteinmetz7188]

Will the auto industry want to build and use a battery that will outlast the vehicle it is placed in? I can see them reducing weight for more efficiency, but are they really motivated to dramatically increase cycle counts?

[@davestagner]

I’m looking forward to that. Range was and remains the main criticism of EVs. But tripling current density could get us to cars that are capable of driving farther without recharging than a human can reasonably drive in a single day. And longer effective lifespans for batteries could give us EVs that are near-zero maintenance for decades.

[@itekani]

@@davestagner I'd say range is already today adequate for the fast majority of drivers. What's lacking is reliable and accessible charging infrastructure. I think the improvements in energy density should mainly be used to make lighter, more efficient cars instead of just adding battery capacity. Especially since the cost will initially be higher for SS batteries.

[@hond654]

I am more optimistic about this tech going into small devices. Take tools for example, having an impact driver that could work all day on a single charge would be a huge improvement over the current devices where you have a rack of chargers and a crate of batteries moving around the site to keep the tools going. Perhaps a phone that doesn't need to be charged every day or where you can have the screen lit more than 10 seconds without the brightness dropping off.

[@kiae-nirodiariesencore4270]

Thanks for another great summary of this particular state of the solid art...so to speak. The problem for all ‘breakthrough’ battery tech is that they and their investors are up against a moving target of performance and cost of existing technologies. An example would be my own car. The Kia e-Niro has an NMC battery from 2019, an age ago it would seem in electric car development. The pack level energy density on the car 147 Wh/Kg, quite acceptable at the time and gives me a working range of 450 km. CATL now have NMC cells in the 250 Wh/Kg range at the pack level and 160 Wh/Kg for LFP cathode. Just a few years ago LFP energy density was not considered high enough for use in cars, now it is where NMC was 5 years ago and is the preferred chemistry being 30% cheaper, more robust, safer and needing no need for nickel or cobalt. At the end of the day it’s all about cost and if non-solid state solutions have enough range, are fundamentally safe and charge fast enough at a low price then solid state, though superior in many ways will not get a toe-hold in the market....Way to go on aviation though.

The issue about all new tech is that there is an important difference between something being possible and being able to do it cheaply. However, all we really need is ability to mass produce the SSBs, there will always be a market for them. A powerful and reliable battery is just the kind of tech where a more expensive option will still find plenty of uses even if they won't become cheap enough to be used in every EV. We already had lots of people willing to drive EVs using lead acid batteries and pay huge sums for cellphones that were literal size and weight of a brick.

[@todddammit4628]

Cost is about scale. If you can scale it, you can make it cheap. So as long as the design uses elements that are abundant and easy to source, and the manufacturing process can be ramped to very high output, it will be cheap over time.

[@haxi52]

@@todddammit4628 @Phoenix EAA. I understand economies of scale will help lower the price, but the price of Lithium has only increased a lot over the past few years, and this one requires a lot more than current.

Honestly I think the great thing is if you take a medium energy density albeit heavy, cheap today technology like lithium iron phosphate, they can do 10 years of daily charge cycles right now for a pretty low price, and are very stable. Get something like that in the new EV's and static batteries we use right now and they'll last us at least into the 2030s when commercial scale solid state is coming online. We needn't make perfect the enemy of the good.

As a farmer, I'd like to see them make a battery standard. Like the AA or AAA batteries, but bigger. You should be able to swap the batteries for different applications. Instead of charging your car, tractor, harvester, you should charge the batteries, and use them in the vehicle you need. It will also drive down the cost of each vehicle, since you could buy them without batteries included.

So far, solid state electrolyte layers have been ceramic or glass. There are few things more brittle. Put that in a car, and the normal flexing from going down the road will shatter the insides of those batteries before it gets to its first charging station.

Solid or otherwise is not relevant just now, the only things that matter are price durability and availability. When a battery can be made (and recycled) at scale for under $10 per kwh in raw materials and labour it will be the standard cell used for the next 50+years. There is a reason brownstone batteries were no 1 for a verry long time, they were never the best but they were good enough for their price. We do not need the ultimate cell at any price, we need functional cells at acceptable prices, better versions will trickle out as we go along but we need to get started with cheap but good enough asap.

The stability of iron phosphate particles and organic solid electrolyte allow the return of cellulose separators aka paper separators. Extremely cheap. Also now as the last base patent for LFP expired several months away Hydro Quepec cannot prevent the use of waste sourced iron phosphate. Until that point only certain methods to synthesize LFP was allowed and only few were allowed to manufacture it. Now it is open game and at least 80% reduction to iron phosphate price is expected. Anode can be organically sourced hard carbon. Just an example is product called Lignode from Stora Enso plc. Similar method allow the use of sugarcane, corn and other sources for anode. Cheap and fast. Now. The thing which brings us to the tooic of this video. Organic solid polymer electrolyte. Long cellulose fibres are excellent electrolyte. Better ionic conductivity than most liquid electrolytes. So here you have it. Practical and possible path to below $10/kWh for cell components. If cell is made by coating the electeodes on the opposite sides of the separator-electrolyte it is possible to use paper machine and curtain coating method. These are industry standards and all machinery is available. This cell type is called MCT-cell (bi-polar, foil-less, thick-film).

[@jeffarcher400]

Since we're talking acronyms I have an idea called FREE. Fast Replaceable Electrolyte Exchange. A large fuel tank of electrolyte could react with conventional lead plates or other materials depending on the chemistry. The tank could be quickly drained and refilled. It would take longer than a gas fill up and you can't go as far so it can't compete with lithium or gas in density. You can make your own electrolyte though. Anybody can start a business with some tanks and solar,wind or grid power. Lead batteries can be recycled easily compared to lithium. Some new design could use salt water or other electrolytes and plates less toxic than lead. This may not beat lithium in the short run but may work well in the long run after considering mining,refining and recycling. Some remote countries may choose a slower pace and energy independence or not have reliable fuel delivery. For household use a pool of charged juice can spread solar power all night and a cloudy day or two cheaper than expensive batteries that will need replacement someday. If you have a tank at your house you can be your own gas station too. A liquid electrolyte with large replaceable plates will be so much easier to repair and recycle then millions of little solid batteries in casings. Imagine getting the casings off, crushing,refining, remanufacturing each solid cell. Imagine the energy and technology needed to recycle lithium batteries. They've been recycling lead batteries for decades. FREE. Fast Replaceable Electrolyte Exchange.

That's only true at current scales. Yes currently research is making Li based storage progressively cheaper as they perfect the details. The countervailing issue, still currently on the horizon, is that at some point we will have used all the accessible Li atoms, and still not powered all our cars let alone the grid storage and planes...

Thank-you for being realistic. A wold changing invention has been only 5-10 years away for the last 50 years. Let's plan on what we have, what's real and what works. In 5 years, we can reassess and adjust as needed.

[@andycordy5190]

Loved the video morphs from what looked like hand made crayon drawings. Very elegant. Regarding prospects for the low mass, high energy density battery, elephant in the room is the competitive nature of these developments. It's all about cornering a market and nothing to do with optimization for the sake of the planet. The few swoppable battery systems I've seen, suggestive of a universal power source that could potentially remove the key problem of charging times, and to my mind a much more natural provision of power in daily life, are so sidelined as to be ignored altogether (I am very excited by the use to which battery swopping is put to use in some Far Eastern Tuktuk operations). The collaboration between Toyota and Panasonic looks like bringing their system (which I assume is fixed battery) to market quite soon and this will certainly be a big step. Congratulation on you continued success.

2:06 - I seriously doubt electric vehicle manufacturers want battery life significantly longer than current Lithium Ion technology. They want people to buy new cars as frequently as possible, and having a battery that will last 500k miles isn't really going to drive sales, since so few people keep a new vehicle that long. The safety, weight and packaging aspects you mentioned are all much more important to car makers than the added lifespan.

[@JacobMunkPlum]

Would it be possible to make a table, with the most importen characteristics of the different contenders to obtain a quick overview?

[@macrumpton]

It took lithium ion batteries, nearly 20 years to move from the lab to any significant amount of production. Even assuming things move twice as quickly. Now we are still looking at a decade before these batteries start appearing in our products. Even if there were no technical challenges, the Scaling of production of a new configuration of battery takes several years. Look at how the famously quick Tesla has been working on the 4680 for nearly 5 years and they're just now starting to roll off the line.

Love your work. I agree, it'll be a while for this to filter through to the real world domestic use, and the cost might be initially prohibitive. I really do hope they do it though, and the sooner the better in my opinion. I'm banking on it going into small devices first. Imagine not having to throw out your mobile phone after only a few years and it lasting days at decent charge.

[@newscoulomb3705]

People seem to keep glossing over SolidEnergy Systems (now SES), which is backed by a number of automakers including Geely, GM, Hyundai, and KIA. They had a functioning lithium-metal battery cell in GM's hands for testing over 2 years ago, and they supplied 107 Ah cells to GM and Hyundai for automotive testing at the end of last year. They are also building a 1 GWH annual production capacity facility that is supposed to open in 2023. Based on what I've seen, SES seems to be at the head of the pack in terms of solid-state batteries, and at their current pace, their batteries are likely to make it into production EV models by mid decade.

just wondering if you follow up on any of these projects you report on???....ive watched a few of your videos and while i do enjoy watching them im wondering if any of them are actually taken up and are being implemented somewhere?....obviously most of them will require a lot more time (windpower cargo ships for example), what about the smaller projects which, in theory could go into full production and start making lives better for a lot of people around the world, like roadside wind turbine, micro hydro power etc....these are the type of things which we could be doing now to give us a start on becoming a fossil fuel free world

One thanksgiving ago, maybe 20 years back, my grandfather said "If you can make a battery that lasts forever or close to it without being killed, that will be the game changing fork in the road for humanity. He was an agricultural scientist, invented the storing of grain, corn, in a silo, without it molding through out the body of its storage. He wasn't a millionaire from this implemented discovery, since he worked for a company or a government program, don't really know. But he was likely to understand the politics that are very real when presenting a knowledge that can be of humanitarian benefit and not collide with an already profit making industry that could take you out

[@jpdj2715]

Great video and well presented. Regarding the subject, and I understand the difference between messenger and message ;), I get the impression that the term "solid state battery" is rather fluid - not so solid. When I think of a solid state battery then I imagine something like a super capacitor where only electrons flow. With single atom thick carbon film supercaps may need very little weight but still need a lot of litres per kWh or MJ. In the meantime, the Volkswagen corp through a Chinese joint venture released a small car with a sodium-ion battery. That's 1st gen and second gen will have more kWh density with double the recycle life expectancy.

[@Kevin_Street]

Thanks for the new video! Solid state batteries could be very exciting, especially if they don't use a lot of lithium. I'm sure the NASA battery performs like they say it does, but it's probably not cheap, since government research is meant to discover new ways of doing things and not make a profit. They're supposed to explore new paths that profit-seeking corporations wouldn't even consider. But eventually they'll license the technology to corporations who will try to find ways to bring down the cost. Probably not by 2030 though. The most interesting part of your video is the rundown of all the car companies that are developing their own solid state batteries. There's so many different ideas out there! It's exciting to see all the different approaches to the same problem. Cost may be an issue, but it looks like solid state batteries are on the verge of becoming a big thing, and quite soon.

@@Vossst Nah, it only leads to duplicate spending, and less risk taking, due to cost. Remember how in ww2 the US made extremely fast technological progress because all companies worked together ? You have better results when you put all the bright minds in one room and give them all the funds they need. Germany on the other hand had multiple small groups working on the same thing, and many projects had to be abandoned because the progress was too slow. That's why now we get all these promising technologies, that lead to nowhere, because each startup wants to be the first to crack it, then they give up.

apart from power to weight ratio and charge/discharge improvements, what are the benefits in terms of the battery lifecycle and materials used?

Not having the pronounced dendrite issue means many more potential charge cycles & slower loss of efficiency. Different batteries are using different materials; one in this video has a graphene electrolyte and I don't think anyone is mass producing that stuff in relevant forms yet.

I find all this solid state battery discussion quite fascinating from an engineering and technological standpoint. The one thing you don't mention though, is that no government agency is seriously investing the money necessary to double the current electrical energy production necessary to convert our entire transportation system to run off of ANY type of battery. I know that electric batteries are just one step in the process of converting the industry, but how do you produce the amount of electricity to run the ever increasing home and business electrical usage we're currently experiencing plus add the capacity to charge all these additional car batteries without using a huge amount of fossil fuels? Even increasing fossile fuel usage to meet this new electrical demand still doesn't address the electrical capacity increase required to charge all these new electric cars. From what I've read as an engineer myself, the way to go is new-design small nuclear powerplants that are safe, less costly, and scalable with no carbon emissions. But the environmental lobby is solely focused on the vulnerabilities of the huge outdated nuclear powerplants designed decades ago. In my opinion, that group's myopic view of nuclear power in general is as outdated as the old nuclear plants that they fear.

One way of reducing the cost of batteries that use Li is to stop the internal competition for Li. Batteries for static applications should be made of cheap, readily available materials, leaving the Li for mobile applications. Just as an example, the amount of Li in the Hornsdale 180mWh battery would be enough to power 3000 60kWh Leafs. The price of Li should be coming down as we find new sources and get better and better at mining and refining but it is not happening. The price is going up due to supply and demand. Alternate batteries include the liquid metal batteries using Sb and Ca, flow and gel batteries based on Zn and Br and a range of redox batteries based on Fe or V.

I've learned to reserve excitement about lab breakthroughs. However, in 2040-2050, thing's will be pretty sci-fi. Im imagining a 100-kwh battery that hangs on the wall of your garage like a poster and it's being charged with 30-kw of perovskite solar roof tiles.
