I was able to track down an article about their independent testing, it’s between 200-1200 cycles before they hit 80% of new capacity depending on manufacturing defects, graphite batteries are 500-1000 cycles but these batteries have between 2-3 times the energy density and charge far faster! They are focusing on the aviation industry because energy density is far more important than longevity for them, and these batteries are good for a much wider range of temperatures. they can use that money to research ways to make it have higher cycle life so it can eventually be good enough for electric cars.

Still feels like the California I knew from a visit back in the late 1980's - full of innovation, manufacturing capability and incredible people!

I've said it before and I'll say it again. This channel should be watched in every school across the country.

Love seeing battery tech tours, because the is the heart of the current transport revolution and green revolution. Hope to see more battery production tours and battery pack reviews by the Munro team.

10C… wow. Megawatt charging, anyone? Thanks Sandy.. that was awesome. Can’t wait to watch them grow and scale up!

Thank you Munro, much appreciated! Amprius appears to be off to a good start. Scale to manufacturing is always the question. It’ll be interesting to check in with these people in a few years.

Getting to scale manufacturing is challenging. Kudos for these guys for putting in the work!

I knew a little about Amprius because of the claimed (and verified) energy density of their batteries but I didn't know that they could be charged so rapidly. Wow!

Import to mention, that Electric Plane startups like MAEVE (Netherlands) are using Amprius as their battery supplier for their planes. They are developing a 40+ seat electric plane for medium distances (< 400 km of flight) and recently unveiled their newest design.

So cool seeing Sandy here! I used to work in that Tesla plant and me and by friends would chill at lunch near a utility box in front of Amprius.

Just incredible to see this industry develop and evolve.

That charge speed tho... from 0% with no pre-conditioning prior to charge. I realize this is not at scale and these batteries are expensive, but if this is a sign of what's possible in the near future, beating the time it takes at the pump would be incredible.

Like watching Merlin bring forth a dragon - this is AMAZING. Rarely do "we" get to watch history put on running shoes and sprint into the future. This is one of those occasions. I thank ALL involved in assembling these technological breakthroughs into a viable product. And thanks to MUNRO LIVE for sharing. So many uses, the mind races. Exciting !

🙋‍♂️THANKS SANDY, CORY and the MUNRO TEAM for sharing this INTERESTING INFO 🧐💚💚💚

Refreshing to see high tech manufacturing in the USA!

The timing of “You know what that means” and the Model Y driving by is ridiculous lol

Sandy is a classic! Munro live is always very interesting.😊 Thanks

Go Sandy, keeping up with this technology is the inspiration of motivation !

♥ *Well done AMPRIUS!* _You too, Sandy._ 😎

I like these tours, it gives Munro Live more video diversity, even though I am a fan of the teardown videos, watching too many of them continuously becomes tedious. great tour, great facility.

Enovix is also in Fremont, and they have an all silicon anode with no nano wires. They can also fast charge at about the same speed, have better thermal properties, and easier manufacturing and lower cost. They are the battery leader in the US, although they are currently concentrating on batteries for Consumer Electronics, but they also do have a program for EV batteries.

I am in the eVTOL industry. This will power up the future of electric flight! Thank you Munro Live!

Fascinating to me, since I have been doing a lot of cell testing of LFP cells for energy storage (mainly to track degradation and thus cycle life). The density they are getting and charge rates are impressive.

Thanks, Sandy. Cool to see 'how' they are doing it. Wish I understood why they think their way is 'the way' to achieve elongated battery power and life. Looks like what we need to assign you to do is assemble a 'battery expert' panel; people who know what's going on and can ELI5 the reasons for moving forward in whatever directions the various manufacturers are moving. Funny, I invested a few dollars in AMPX upon your 'breaking news' segment a month ago. Now I can't wait to learn more about them and the industry in which it operates. Battery potential will lead the way moving forward, for sure. ALSO- right across the street from Tesla's battery plant? WTF? Ha! I gotta think, as 'turn on a dime' as Tesla is when it comes to improving its processes and products, if Amprius has anything of value to offer, Tesla has already found a way to incorporate it. Yes? No?

Thanks for showing us the future! I'd said to many people in the past that the e-mobility is right at the beginning. The battery-story is starting right now and the end you can't imagine. Nice to see this post which come from the future, doesn't it? Gratings from Germany!

Mind blown .... and such an insight of expertise from around the world to save said world ... brilliant !

Using CVD as basically a mechanism of doping is nothing short of absolutely brilliant. The elephant in the room is scaling. The amount of energy and time it will take to scale this would be astronomical.

"This is one-of-a-kind, and there are TWO of them" :)

Amprius is a company that specializes in the development and manufacture of advanced lithium-ion batteries. The company was founded in 2008 as a spin-off from Stanford University, and its technology is based on research into high-capacity silicon nanowire anodes for lithium-ion batteries.

Awesome. Thx Munro Live for sharing your tour.

God I love these new techs coming into play in my lifetime. Thank you Munro live!!!!!😁

You got me on that. Didn't know that Amprius is literally right next to Tesla in Fremont. Very fascinating on the raw talent we have in the US and you guys are shining a light on this. I've learned so much from Munro Live and thanks for this. Absolutely incredible.

Of course, just after Sandy provided us with the short trailer for this Amprius video, and showing this, CATL announced a 500Wh/kg battery which they are about to put, or already are, in production. It seems that battery chemistry tech is galloping along now. This is all tremendously exciting stuff.

Thank to Munro Asso and Amprius for this fascinating factory tour! This combination of high specific energy and extremely fast charging should enable electric aviation and other applications.

0% to 80% in 6 min is very impressive. Assuming this scales up well into a full pack configuration, it bodes well for the future.

You are doing an awesome job Sandy, kudos.

"these are one of a kind.... and there's two of them". Great tour, and I can't help but like pleasant intelligent people.

thanks, Sandy and team.

Interesting information. Relevant to anyone considering purchase of the stock. Sandy Munro isn't biased by Wall Street shenanigans. An engineer's perspective.

6 mins from 0 to 80% is pretty nice. I wonder how long the life of these batteries comes out to be.

How many cycles can it do?

Sandy - I appreciate you more than you know. Thank you.

Excellent work team . Enjoyed the video.

Intro was hilarious. lol

Welcome back to the bay ✌️....Love the Show .... HOPE EVERYONE HAS A BEAUTIFUL DAY...

I'm very impressed. Thanks so much Sandy

Thanks Sandy for sharing with us Amprius' manufacturing EV battery process and testing.

Very impressive thanks for the tour.

this is Great Sandy, Would loved to have been there, looking over your shoulder , so many questions... So exciting

ANother video that no one else has provided. Doing great work Sandy.

Thanks Sandy! You are the best!

he got me so bad with that introoooo love everyone at Munro for sharing more

Very Intresting, Took the Tour also Via Video this Morning ☕️ Super Great 💛 Mr. Monroe Seems Very Impressed!! ANOTHER GD Day!! ☀️☀️

Mithun if I have spelt correctly, looks like guy you want on your team. Not the most exciting job-but critical for performance. Unsung hero👍

The warning labels on the test jig, "Non-Professionals Do Not Open". Classic

interesting factory visit , great to know practical information about battery thank you

Even if the packs are initially more expensive, they will still work for aviation as their gravimetric densities are industry leading. There were questions I would have asked: Is this LFP? Or what chemistry. Will standard BMS work with these cell? Beyond the prototype assembly line, what is the timeline to scale? Are they working with any partners?

Great video and I look forward to a great future for Amprius Tech.

Fantastic facility. Very excited to see this technology proliferate. And great to see that it's happening in the USA.

We are living in a great time to be alive ! I was born in 1948, a few months after Bell Labs reported their invention of the point-contact transistor, & I grew up in a small agricultural town living on my parents' apple & pear orchard. As a prepubescent boy, I brought 1930s-vintage vacuum-tube radios home from the local garbage dump {long before they acquired barbed-wire fences & the name "landfill"} & got them running again. That was the start of my electronics career. A high-school buddy & I bought our first transistors {2N107s & 2N170s} in 1963 by very slow mail order from Allied Radio in NYC to build our first TRF quasi-crystal-set battery-powered radios. A long time ago in a galaxy far, far away ! Now retired, I have my name etched into circuit boards residing in pressure cases on the floor of both the Atlantic & Pacific Oceans measuring deep-ocean water pressure, as well as in magnetometer instruments in a now-defunct small Canadian science satellite in a polar orbit around the Earth. What a ride ! Thank you, Munro & Associates, for a wonderful walk-through of a bleeding edge American battery plant. More, please, I beg you !

That charging speed was almost as quick as filling up an ICE vehicle. Bring this to scale and say good-by to long wait times to charge your EV. Very impressive. Thanks, Munro!

Another great video from Sandy Munro/Munro Live!

Great video!

Really freaking impressive! Exciting times.

This is fascinating, but I wish there was an intro video because I felt like I came into a conversation half way through.

Yep, 0..80% SoC at 10C in 6 minutes flat is astounding for a cell with 370Wh/kg energy density. CVD is expensive but if the oven process to grow nanowire layers can scale economically then this should be revolutionary.

Sandy. As a newbie a bit of a lead in to know what we are looking at and why would have been helpful. Had to read the comments to understand what is going on. But thanks!

Nano wire sponge cool❤. Possibilities are only limited by imagination, definitely a takeover target for use in Optimus and long range EVs(with improvement in vibration resistance and high capacity charging). Cooling could be novel too, Imagine dunking the nano wires sponge, in flood filled coolant trays, on demand. Just some thoughts.... Special thanks to Sandy and Cory for bringing this exclusive content👍👍.

Great content Sandy, TY

Awesome 👌 Scale as quickly as possible

Sandi is always impressed, and he doesn't even know what he is looking at!!! Always entertaining,

I worked in silicon fab for 25 years (in Mtn, View, CA by the way). With deposition this looks remarkably similar.

First heard of Amprius from the Electric Viking, awesome to see Sandy Munroe get excited about this.

The nail penetration test on the Amprius KZfaq channel is also very impressive.

Seriously cool. Thank you.

Great tour and video. These must be very small cells if 10C is 27A. This is why the SOC% goes up so fast. Rough estimates (if my math is right): if we estimate that 0-80% was 6 minutes @27A (10C), this calculates to about a 3.3Ah cell. Just for reference, the Mustang Mach-E cells from previous videos are about 70Ah each...so 20x bigger.

Great video, Thank You! Sounds like the GOOD is high power density and fast charging time, the BAD is high cost and low cycle life. Could be a good fit for aircrafts, if the batteries are easily swappable like NIO in the auto industry?

Even if they're initially expensive, I doubt they're too expensive for the supercar and hypercar markets. A manufacturer that wants to keep the car light would be interested for sure.

amazing tech development great video

I hope with Canada getting the China made Model Y LR with the lower cost battery packs that Munro''s team gets one in for a full review and rip it apart for the deep dive examination. Maybe a Model Y have a car insurance company sponsor the series. Munro Live has a good size audience that should appeal to many companies. Back in the early 2000's I worked for TechTV Television Network and we has small audience, but highly tech nerd focused, which certain companies struggled to reach, thus TechTV was like gold to these companies. I believe Munro Live has a unique audience and will likely be reaching people that traditional channels or media do not normally reach. I hope your team is able to get packages put together to bring on more sponsors so we can get more content. Keep up the great work.

Nice the see the SMIT and Centrotherm lines at work there👌

Amprius is legit. Wow, such praise by Munro.

There's an Amprius PDF presentation that they gave to NASA. The battery technology has very high density, almost twice that of current carbon anodes, and a very fast charge time. This was demonstrated in the video. But the number of charge cycles is troubling. From about 80 to 200 cycles. Amprius batteries with significantly less capacity reach almost 600 cycles. Tesla lithium bats provide about 1,500 cycles. You may notice that this significant parameter of a rechargeable battery, cycle count, was not discussed at all. And Sandy didn't ask.

they say: "we are ready to scale up" I hear: "we have no idea how hard that is going to be" They've done 5% of the work so far.

dangit I just missed out an opportunity to meet Munro! bay area guy here and big fan!

AWESOME!

As a material's chemist, I was left wishing for someone a bit more familiar with the topic to do the interviews and make more questions. The setup seems quite interesting, but they didn't give a lot of details (I can understand why, trade secrets and so on).

That was good!

Amazing!

it's funny that we continue to talk about not wanting to go to 100% charge so we're left with a usable of 80-90%. Why isn't it reframed to 100% with a built-in buffer of x%. Would seem to simplify the understanding for more people. Charging apps would be written to go the non buffer 100% state.

How fast does the anode go through the reel to reel process since vapour deposition is super super slow? How many years away are they from moving to production? I imagine they invited Sandy to get interest, to get money for scale up or further development. How much will they cost relative to current cells. ....Presumably a lot more expensive and at the start they'll just be for niche applications.

The greatest part about Amprius is that all these gains are basically at the anode level. They will be able to combine their anode gains with advanced cathodes and separators to really shine.

I‘ve known of the Amprius technology for some years through my work in the battery industry. I wonder what the cycle life with such fast charging is now for them?

7:38 Baby ruperts! Excellent science!

your a hard man to impress Sandy ,so the whole thing is impressive , good job. how long will this tech take to get down to street level ? be safe from Dublin, Eire.

Good program Sandy 🤓

OMG! Just checked their website. Seems legit. Thank you for always bringing interesting info to the masses. Tesla should buy them out before they go public.

Just the intro earned the like

Great stuff

The big limit to traditional batteries charging time is heat build up. Graphine allows electrons to pass through unimpeded reducing friction between the electron atoms
