Agreed; probably could’ve been done off camera or edited out.

[@wildweav]

I've seen so much solid state battery news that isn't seeming to go anywhere that i had kind of tuned all it out. When Sandy says this is interesting then I pay attention. I got excited when he said that the raw materials are sourced within the US and that is what that they need to manufature the batteries. It reminded me of the original idea of the Ford Rouge Plant where iron ore went in one end of the plant and a car came out the other end.

[@beerzerker8359]

Sourcing materials within our continent is going to be what either makes or breaks the EV industry in North America. If we get get past the range anxiety issues by mass manufacturing solid state batteries, you will quickly see EV adoption go through the roof. The question is whether we can develop the infrastructure within North America to generate enough electricity to power 300 million EV's in America and probably another 35 million EV's here in Canada.

[@louiec.9782]

Don't know if anyone caught it but the Saku guy said at the beginning that they haven't yet developed a solid state battery.... lol

[@patreekotime4578]

​@@louiec.9782 yup. exactly. They have great technology with a mostly dry process, but a liquid electrolyte at the end.

[@QALibrary]

@@beerzerker8359 you missed out on a piece of important information... Everyone does not go to the gas station all at the same time on the same day! It is the same with charging an EV and most charging will happen overnight where 75% of power stations can be offline due to no demand so when you use your head... Countries do not need more power to charge vehicles - it is better for the power producers because output should be stable all throughout the day or with much lower peeks and troughs and taking power plants offline or only running at 1-5%

[@DavidHalko]

@@QALibrary- “everyone does not go to the gas station at the same time every day” Ummm… it is called “Rush Hour” for a reason. When 30% rent a flat in the US, those poor folks will be charging relatively at the same time… within a few hours in the morning & evening. That will be a massive problem, since that one times are not at peak solar production times. Overnight will also lack solar, for the 70% in North America. Carbon energy sources fulfilling those EV charging needs as well as when Air Conditioning [cooling & dehumidification] & heating is needed at homes & apartments.

[@QALibrary]

for everything I have seen and read about in Solid-State Batteries, this looks like the real deal

[@nononsenseBennett]

I am so impressed with Sandy's knowledge even in developing technologies. He's a true learner.

[@ctuna2011]

He has developed a lot of stuff himself. That is why he has all the critical knowledge to able to critically review this stuff. What about expansion and contraction due to charging cycles and for that matter cycle life. There is so much battery research going on right now enough to make you dizzy.

[@motofunk1]

Yeah, caught that… But their process is close & getting closer… let’s hope they make it! 🎊 🎉

[@JigilJigil]

I love these battery startups tour, keep up the good work.

[@lgrantnelson2863]

Nice video. Custom printed battery shape. As the video progressed I noticed the copper lines mounted on Kindorf channel hanger brackets on the walls. I used to install lines like those for water, air and oil to supply CNC and cam machines. Even suggested a water line to chase solids so they wouldn't clog a drain. After checking around they had me install one. Informative video. Tech is progressing. I'd say its taken about two hundred years for battery tech to come this far in the US. It's exploding now.

[@patreekotime4578]

Well, literally 113 years since Edison brought rechargeable Nickel-Iron batteries to market... and they still use them in New York subway cars!

[@bradcavanagh3092]

This tech sounds like dynamite for power tools!

[@danapeck5382]

Thanks, interesting direction, hope it scales

You and me both!

[@jimanderson4444]

Yeah,seeing this technology is pure inspiration, . It says electric aviation is here ! Long range ev ! Thanks Sandy .

[@ryuuguu01]

Although most of the video focused on cars, being able to make exact 3D shapes ( not just 2D prisms) will be worth a lot for the consumer electronics industry. They will be willing to pay a premium for this. For things like smartphones, smartwatches, cameras, and handheld game consoles custom shapes will reduce overall size and manufacturing costs.

[@BTSloan70]

I noticed on the info board in the room, it took only two years to go from 40 Wh/I AND 30 mAh to 800 Wh/I and 3000 mAh. Very impressive. Would like to know how fast the charging rate is and how many cycles it is good for. Lots of cost savings on the manufacturing.

[@taciusarias2608]

500 cycles ; 80% of the battery capacity... 750wh/kg battery...

[@SomeGuyNamedPaul49]

Being able to make different sizes of batteries which are smaller and lighter sure sounds like something Aptera would be interested in.

[@nononsenseBennett]

Good point!

[@JMeyer-qj1pv]

Looks like it would be good for making wing shaped batteries for aircraft and oddly shaped batteries to fit into electric motorcycles since both applications need high energy density in non-square form factors. It is frustrating to see all these potential advancements in making cheaper, better batteries, but they never seem to make it to production.

[@gianluigicassin868]

Well, technology takes time. It's a lot of efforts to really understand what works and then you need to refine your solution to the point it is commercially viable. In the meantime there's a lot of testing and for batteries, long term cycling can really take months. This is even before customers can validate something, cause you don't want to fail in front of customers. And finally, there's the scale up part. So, lots of years to get there, a long time before take off.

[@nononsenseBennett]

Good idea

[@patreekotime4578]

​@@gianluigicassin868Time, luck, and money.

[@DavidHalko]

“wing shaped” Hopefully, they will print roof shaped batteries, hood shaped batteries, trunk shaped batteries, fender shaped batteries. There is no reason to need to place huge cells on the bottom, where people can damage it on a spine crunching speed bump or large pothole.

[@nononsenseBennett]

Give it time. New manufacturing processes will be invented....probably by Musk.

[@BokoMoko65]

Mr. Munro totally missed the point in this video. Mr. Niestoj's business is not battery manufacturing. His business is selling factories that make batteries and other things too. This became quite apparent around 14:30 in the video when Mr. Munro asked about the machine's production capacity, thinking in terms of cell units, and Mr. Niestroj responded in terms of energy units (KWh).

[@arwedniestroj3330]

It is our new manufacturing approach that enables improved batteries from improved manufacturing. So it is both.

[@DavidHalko]

Cell production is useless, when a cell could fit in a phone 📱 or be the size of an airplane ✈️ wing. KWh makes more sense to them in this arena.

[@mefobills279]

Part of the processing is ink jet. This allows scaling, and also continuous flow (not batching). It looks like a viable roadmap based on Sandy's response.

[@patreekotime4578]

That stage is optional. Probably for marking and/or branding the cells. He said that any number of different methods could be used in that stage. It is up to the licensee to decide how they want to use that stage of the machine. So they've basically eliminated a secondary stage that the licensee would have to figure out themselves and build it right into their line.

[@mefobills279]

@patreekotime4578 Throughput for large surfaces implies inkjet, not 3D printing. Providing, of course, deposit thickness is controlled adequately.

[@stulop]

The idea that you can make a battery in practically any shape. In a car you hide the pack all over the place leaving floor and cabin space free.

[@hallkbrdz]

It will be interesting to see how this stacks up to the Amprius cells when mass produced vs small volume samples.

[@stevecornell8260]

Fascinating ideas that all stem back to material science.

[@rockycata6078]

My dad was born in 1898, lived for 105 years, and he never stopped stopped learning. "Live long and prosper, Sandy"👍 The "process", using the 'special-sauce' electrolytes, is key to doing dry-cell/solid-state batteries. What is interesting is the capability to have a process that is "chemistry-agnostic", and can deliver energy/volume/weight ratios that are cost-effective. Battery-structures are not standard, such as AAA/AA/C/D...2170/4680 etc, and looking forward to a standard battery structure that is interchangeable between EV manufacturers. Is there too much steel for 4680, and is it the best format for pack integrity?

[@ilcomendante]

Benefit of additive manufacturing for geopolitical reasons. Now that's an angle I don't think many considered previously. Great episode

[@DemaGeek]

Is a video possible speaking to the attributes of this battery makeup which determine it's life and capabilities, such as: Tendency or resistance toward dendrite formation, expected usable cycle life, any of the charging characteristics, etc. This would round out the overall picture and be very much appreciated!

[@visualconfections]

Impressed, how will they hold up to heat? Can the be made in wafer shapes or even have ridges to maximize surface area. Would SLS WORK for this process. And for the layering , the process they showed is very inefficient. Assembly line mentality

Should ask how many chief of engineers they’ve had in the last 2 years. 🤣

[@azorglub]

400 cycles to 80% retained capacity seems on the low side for vehicles. However, if cost competitive they could probably make batteries with more capacity so as to use less of it during the normal charging/discharging cycle and extend the overall battery life

[@StopTheBurn]

KISS - Keep it simple Sandy

[@Weezedog]

My biggest concern with additive manufacturing for making batteries would be the quality control and consistency. We've seen what happens with errors causing batteries to short out and catch fire (Bolt EV, Samsung Note, etc). It can kill people. Every single layer needs to be consistently safe.

[@TennisGvy]

Do you ever see liquid batteries like influit as a possibility?

[@1Snouser]

Please pursue a tour of Enovix batteries!

[@Cloxxki]

What capacity and energy density might be achieved with this, cramming it into a well know pack size we not see achieving 100 kWh wet Li-Ion cells?

[@johnpoldo8817]

It’s so pleasing to see this development and manufacturing in USA. This company has very exciting battery technology, but only if they can produce batteries in volume. We must divorce reliance on China. I would never buy an EV with a Chinese battery or motor.

[@michaelmara1338]

If they can scale this process and get it tested in real world EV applications then I would say that it has a lot of potential.

[@bagofholding]

[@freeaccess5905]

It is an interesting tour, but Sandy is dead wrong at the 25' minute mark when he says there are no US manufactures of slot die coating system. There are many made in the US that are used in numerous industries that require just as much precision as that "battery" line.

[@madtscientist8853]

FINALLY someone's Gets the idea of using 3D printers to make batteries. We can make them SMALLER ,more COMPACT, and more Emergy dense. I've been thinking about this for about 10 years. But metal 3D printers are too expensive for me right now.

[@wolfgangpreier9160]

Imagine 10 million robots making 3D printed battery cells for the Model " 4680 integrated battery pack for 10 million Model 2 each year. 450 cells x 10 millions x 1.5 scrap = 6.75 billion cells. I guess Tesla will not implement this process. It does not work in this dimension.

[@heavenlyReza]

Lol....platform in persian That was very intersting

[@tomgunn8356]

Looks to me that Tesla ought to scoop up this company pronto. First for the powder enhancement so that it flows smoothly, and then for the additive manufacturing process.

[@Cloxxki]

Any large brand with actual ambition to do better. Tesla seems to err on the side of cost reduction rather than best they could make. They'll remove indicator stalks if it saved them a dollar, no matter how dangerous that is for rental drivers and even owners and put some buyers off.

[@zodiacfml]

I have serious doubts on his estimate of a battery coming off this line every 10 seconds or so. His estimates of 100megawatts a year coming out of one of these machines.. yeah.. ok.. great.. prove it. Cause I'll believe it when I see it on sale as a cost competitive product. Until then.. it's a cute idea to throw gobs of money at. GL to em. Ever heard the expression, prototypes are easy.. volume production is hell? He keeps saying their energy density is higher.. ok.. 800 vs 730.. great, we can all see it's a 10% ish improvement in energy density that can extend to added range or reduced weights and better efficiency.. and maybe faster charge rates? Cycle lifespan increase? He didn't mention any of that.. but Ok.. lets say all of it is what people dream of in these solid state batteries.. but it costs 4 times what that cylindrical battery at 730 density is.. who's buying it? Not the average joe. Not for decades. But sure.. it's gotta start somewhere. Hope they figure it all out and are successful. Again.. I'll believe it when I see it. There's only been 100s of other companies talking about their solid state tech that will be out!! In 2015.. 2017.. 2020.. 2025.. 2030.. 2040.. all a bunch of hot air so far. But, glad they're chasing the dream.. someone will crack it sooner or later and it'll trickle down over the years to improve everyone's lives.
