Love it! thanks guys!

Sandy: "I care about my people" I give THEM gloves, but I pick up this stuff bare handed. 🤣

It’s great the dry cell process is now working and in production. It will only get better and more reliable from here on out! Can’t wait to see Gen 3 4680’s.

Says he does have gloves, not going to touch stuff… almost immediately picks up 4680. 🤣

Tom is a real engineer. He needs his own show!

🙋‍♂️ THANKS SANDY ,TOM AND MUNRO FOR SHARING THIS INFO 🤗 🔋⚡️⚡️⚡️

Super interesting, thank you!

Extremely informative. Really explains a lot about what makes a battery and how these work. Well done. Hats off to sandy and the team!

wow. Looking forward to your charging/discharging characteristics and capacity videos. I love to see Tesla innovations kicking in.

Awesome! Amazing job as always. Thanks for sharing!

That's the one I've been waiting for thanks sandy team u guys are awesome 👌

Another excellent video presentation. Thank you

Another great content. Thanks for sharing this.

Sandy and his team are awesome

On the edge of our seat waiting for a wh/kg test. Thanks Sandy and team!

for long time, first video on channel that i watched from start to end. very informative and interesting.

Sandy slamming his 4680 shot down on the table 5:00. When do 4680 shot glass sets become available in the Munro store?

You know Sandy's Canadian when he calls bags begs

Hello from Azerbaijan. Thank you..❤❤❤

This was interesting!

This teardown drives home how fast they’re innovating and that it’s still early days

Good to see silicone in the anode. It should also help with the charging curve as they make some updates.

Soo, what I'm getting is "almost eliminated cobalt" and "no manganese". "Some silicon in anode".

good job!

The general layout of the tab-less cells made incredible sense when shown at battery day. It’s been a long road to getting these ramped up to full scale production AND better power than 2170 and others. Still waiting patiently 🤔 Thanks!!!

nice video guys, i would suggest taking more closeup photos of some elements and having them part of the video if it does not require too much editing, great job, thank you for the insights!

Interesting take on the evolving tech in these cells, I'm very curious where this will take Tesla.

When in doubt, just call it cathode. Great video guys :)

Thanks great video. Hope they phase out old-fashioned 2170 and 1865 asap and migrate to this design for all ternary cell.

Thanks fellas :-)

This channel is just a pleasure to watch. Senior experience smart engineers get into details and then show a passion for what they do is fantastic. Keep it up Munro and Associates!

Tom become greater and greater😆

Question? What's the RATIO of the electrolytes? Still using Lithium I'm guessing. Are the 4680 cells more ENERGY dense then the 21700 or the 18650 cells? What's the overall cost comparing all 3?

Tom is a great speaker.

CyberCell is a great name

Is the case still Ni-plated steel?

Can you speculate on the significantly reduced charging curve of the Model Y 4680 vs 2170 Teslas?

Cybertruck ❤❤

Good video! Congratulations from brasil!

Removing the "spider" and welding the anode to the case was almost certainly done for improved thermal conductivity. That spider was the choke point in an already difficult to cool battery. Glad to see the improved vent scheme. The "structural" pack teardown was a bit scary. If the primary vent failed and the anode end opened it would be very ugly.

I was hoping to get the cell shell thickness comparison as well :)

Considering the energy throughput of the entire battery system, having a perforated secondary vent might lessen the explosive potential during failure. The battery would undergo an expansive deformation and baffle some of that energy. This is by design...

👍

It seems that the latest generation CATL batteries are still more advanced than Tesla's

CATL has huge advantage - been making huge number of cells for decades, huge head start, subsidies, exchange rate advantage. I hope 4680 can make a go of it. Chemistries are in flux, eventually some chemistry will emerge w/ zero cobalt, zero graphite.

Is the cathode the convex or the concave side of the jelly roll?

I’m curious to know if from the Texas plant the same cyber truck battery also goes into the model Y for 2024; do y’all know?

Now that CATL have the superior battery tech. Do you think its time to ditch these types of cells for full LFP as you can see the latest generation is way better for all sorts of reasons as well as no cobalt.

how do you weld the complex flower to the cap?

Both the copper and aluminum rolls go into the can ?

Tom has a lot of information to provide. I really enjoyed his analysis

It’s always great to have a ventilation unit, but Y’all should also always think about investing in some high-end 3M Masks.

Would like to know the rrelative energy densities (next video), but now we know that they have both: Dry process on both sides (which should allow much cheaper production with no ovens) Silicon and much lower Cobalt.

you can see the perforation here: puts the finger right on top of it and the whole thing semi unfocused.

@12:35 it’s an NCA cathode, right? I wouldn’t expect to find much Mn (if any).

I like that he explains it in a way us average people can understand 👍😊

Good day from Goonellabah, NSW!🌏 When we get the Cybertruck, we will provide battery maintenance.

Sandy! Please teardown and evaluate byd blade batteries

Would love to be able to purchase these cells for various projects, wonder how long until it’s available

How does the charge cycle total up? A full cycle is from empty to full. How do you tally up a bunch of small charges. Are those considered as 1 cycle?

Are the Cylindrical cells better than the Blade cells in terms of energy density assuming same chemistry is being used?

Is the cathode always the top-side of any battery while the anode is always to bottom-side?

Gluten free jelly rolls! Tasty!

Adorable voice whoever does the ads

11:58. There's no manganese? So they're reverting to a nickel-cobalt-aluminum (NCA) battery? Isn't that what the old Model S used to have, I believe?

Sandy, please check out and tear down byd blade battery pack

@Sandy & Tom: Get me some samples of anode/cathode and I can do EDX elemental analysis if you wish.

Made in America battery, dry cell. Most other manufacturers forgot to Build battery factories buying all their batteries from expensive 3rd parties in Korea and China. Tesla also offers LFP batteries with no cobalt or nickel which love 100% charging/minimal fire risk. Competition trying to catch up to LFP. China is at the forefront of LfP batteries

👏🏻👏🏻👏🏻👏🏻✌🏻

Thanks so very much Sandy. As an investor, the 4680 has been hair pulling as its holding up Semi, Roadster, Not Model 2, even with Cybertruck now ramping. Was looking to see When they would inject Silicon in the cathode, When they would have dry process on both sides to finally eliminate the ovens and what the energy density will be. They were originally targeting 300 wh/kg, think they can get by with 280 wh/kg and still produce Semi at a reasonable price (esp with fully dry electrodes)... and clearly they are in no rush there if the factory construction rate is any indicator. Aggggghhhhh! Mexico, Semi, Not model 2... delayed because of ???? Don't get me wrong, Many good things, but all the hair pulling seems to lead back to 4680. On pins and needles for your energy density findings. (Christmas is comming... don't want coal!). So very much abliged that you are doing this. So little info on the One metric to finally tell us where we are. (240 wh/kg was a Huge disapointment).

you mixd up cathode / anode - aluminium/ copper cobalt / manganese

what is the voltage of the cell? since you didn't mention it I assume there's no Lithium.

Are you going to do a tensile test on the stainless steel exoskeleton? The toughest stainless steel alloy I was able to find was 1'690 MPa and 25% elongation at break. So that's 400 MJ/m3 of toughness, up there with spider silk and superalloys.

This is proof that Tesla is also concerned with the safety of it's vehicles. Fact that they have a blow out space built into the pack is something I hope never happens but it gives me piece of mind.

отчего образуются газы ?

The Cybertruck battery is supposedly 123 kWh. How many cells are there? I know "rated" is slightly different than actual but it would give us a start on the energy density math.

So idk if it’s just me or not but they didn’t explicitly say this was dry cathode?

The real question is.. is Tesla sandbagging these 4680's for now while they 'test' them. Or is the performance they're showing, all they're capable of? Because they are NOT charging at the speeds we hoped for.. and they are NOT extending range to levels we thought they would. And it's doubtful Tesla is yet seeing any cost savings.. yet. So if they are not sandbagging the performance of these cells while testing, and will uncork them in the future when they're certain they can do so.. well then the whole 4680 transition seems to be a dead end.. for now. These were supposed to give CT a 500 mile range.. AND way faster charging and a better charge curve.. it's got neither. If they can't figure out how to GET that kind of performance out of these cells pretty soon.. they'd be better off re engineering the whole pack to work with some of CATLs quite impressive batteries.. or any other battery manufacturer who's got the chops. CT needs more range.. at LEAST as an optional pack, for those who plan to use the truck for towing and whatever other reason a person wants. AND it NEEDS to charge much faster.

get a et some fume hoods

Interesting that Munro was schooling Tesla on body design and structural components and here, in the battery arena, they are struggling mightily to keep up with Tesla and "learn" this battery echnology.

Cybertruck specs were originally promised, seemingly base don having 500 Wh/kg cells. Range numbers are WAY off in the vehicles to market. Even down on the competition. Will they have breach 300 Wh/kg with this generation? NIO is putting 360 Wh/kg into service now, their cute sedan will have 150 kWh against Cybertruck's 123 kWh...

"...what we know, from watching one of our competitor's videos,..." *record scratch* Who competes with Munro?

Safety third

Dry cell and silicon anode. 🤯

They need to use gold to reduce the amount the things degrade, like 1%.

The main metal in the cathode is lithium.

Is Sandy wearing a Doxa watch?

Ah yes the most compelling battery in the industry.....

Don't try this at home! Do it at work where you're covered by Worker's Comp. 🤣🤑

Sandy this message is for you, in the beginning of your message you mention particle dusk from the batteries and I am sending you this statement. Three person has DIED AT A NORTH VOLT factory in Skellefteå Sweden where they are making batteries for BMW, VOLVO other OEM. My point is that three of there personnel had pass away in there factory and I believe 😢 that they do not have a good filter system in this factory and I think you should reach out to them from a engineering prospective.😢

Will solid state EV batteries ever be a reality? They almost sound too good to be true.

At 8:00 Tom says they've largely eliminated the cobalt from the cathode. Then at 11:50, Sandy says it's the manganese that was removed...so which is it?

Im still got convinced with the 4680. Elon said its meant to half the cost of the battery pack. So far its only more expensive, heavier, and slower charging.

Really? Only need to remove manganese to complete the dry anode process? ! And the energy density has reached the advertised level? ?Look forward to the next more complete analysis video.

Disappointing that some cannot imagine technology progressing.

A very safely done video despite some inconsistencies between what as said and done - do as I do, not so much as I say. So, the cathode is NCA and likely made using the dry process. The CT ramp is going well (1,300/wk??) and perhaps LG is supplying additional motherroll for both cathode and anode for a portion of CT cells as LG anode was seen near the Austin cell can scrap bin. Looks like Tesla has completed structural changes to the Austin building for the second batch of cell lines and will have all the equipment installed by year end. But getting it up to operating speed may take awhile. Given the extra capacity of the cells, and the 'reserve' for degegration and operation below zero miles of range left, the nominal capacity of the CT cells could be 100 Wh - thus nominal pack capacity could be 134.4 kWh, rather than 122.4 kWh. Thus the nominal rating of a new cell could be 10% higher than the usable quoted by Tesla.

If I ever have to replace my Tesla battery pack, this the battery I want. That way I can charge 100% all the time without worrying about battery degradation. I do use the battery type chemistry to store the power from solar panels at my home.

Tesla offers diversified batteries from 18650, 2170, 4680 tabless dry cell, and prismatic LFP batteries. High performance batteries typically NCA or NCM. Entry level batteries for Tesla LFP. Lfp not as energy dense but cheaper, more cycles, loves 100% charge, rare fires, no cobalt or nickel.

What does BYD use? Leader in evs...
