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

[@tesla_tap]

A sealed cell is not a concern. It's the opened jellyroll that you don't want to touch. Even then, it's not clear if it is toxic or not, but smart to be safe.

[@TheLobo91]

Do you put on gloves when you pick up an AA battery? Or even 12v battery? It's 3.3v lol

[@chrisborns5972]

It's not a bomb, sealed cells don't have exposure to hazardous materials.

[@JGtheone]

I don't believe that touching a lithium jelly roll is that a concern. As long as you wash your hands afterwards it's maybe as dangerous as having some gas on your hands after filling your car. I assume Sandy has touched a lot of extremely poisones things in his career. The jelly roll shouldn't be a big issue. Of course, eating or breathing that stuff is definitely a very bad idea.

[@tesla_tap]

@@TheLobo91 - The voltage was not the concern, it's the possibly toxic/acid compounds from pulling the battery apart, although the concern could be overrated. Better to be safe when you don't know what you're dealing with.

[@markplott4820]

50% more cost Reductions.

[@royh6526]

Partially. There is evidence that Tesla is purchasing cathodes (wet process) from a Chinese company for the 4680 cells made in Giga Texas. The suggestion is that some cells are made with wet cathodes and some with dry. Clearly Tom Prucha thinks that this cell will prove to use the dry process, but doesn't know yet until more testing is done. The one new thing I learned was that the anode has some silicon in it.

[@NilsFrederking]

It is till speculation, deducted from the lack of manganese. But of course that would be big news, if they managed to also coat the anode with the dry coating process, as Tesla then could ramp the cell production by adding new production lines.

[@duncanidaho9153]

They better hurry up - the competition seems to be moving much, much faster.

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?

[@marcusoutdoors4999]

That’s what I want to know. Some people are speculating that we will see a longer cell eventually as the Cyber truck battery tray could compete with a 4695. Overall though it seems that the 4680 isn’t performing… just yet.

[@dogbreath6974]

"Are the 4680 cells more ENERGY dense then the 21700 or the 18650 cells?" I would hope so, otherwise it would be pointless. They are probably 3 times the energy than 21700.

Tesla, Inc.'s latest earnings show deteriorating fundamentals, with a 9% drop in revenue and a 55% decline in net profit margin. EV deliveries have decreased, operating expenses have increased, and the stock price remains high compared to competitors. Risks to a bearish thesis include potential innovations, market share growth in China, and strong global EV sales. But the stock is highly expensive, while the recent news is not encouraging.

@@markplott4820 not quite. Graphite content won't exceed 30% in most cells and can be below 20% in some. the anode active material is usually graphite, so it's very important, but the rest of the cell (cathode, separator, electrolyte) doesn't contain any graphite. and the anode itself has a lot of other stuff besides graphite, like binders (plastic glue-like particles) and the copper foil.

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!

[@airheart1]

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.

[@salland12]

i think Panasonic is sandbagging these 4680's cells

[@jonbenet1272]

I don't think they are sandbagging, the 4680 is a dud. The next gen will most likely be CATL prismatic cell, using CATL's CTP 3. Tesla has been pulling equipment from CATL's factory in Shanghai in order to make a LFP cell in the US. Tesla was probably going to use cells built in China, but had to move manufacturing to the US due to the Inflation Reduction Act. In one of Sandy's videos, He talked about the extra room in the pack for thermal runaway. Maybe, but a prismatic cell would fit pretty well in there. Should be interesting to see what chemistries CATL will use, I assume they wont be Nickel rich, most likely Mn rich LMFP. The new hybrid Sodium-Lithium should be neat. As well as all of the fast charging innovations they have been making.

[@w0ttheh3ll]

Tesla have publicly stated to investors that they are hoping to reach cost parity compared to external suppliers this year. That is, they definitely don't see any savings at this point.

[@ralanham76]

If they made a double height battery pack they could get 500. But then they would make half as many trucks. 😁

[@CorwinPatrick]

@@w0ttheh3ll Tesla has also publicly stated that the 4680 is a Backup Plan. While I don't think they are actually Sandbagging, and are continuing to put effort into them, they were always going to be lagging in development. However, actually having a battery is better than no battery. The break even point will move with the dumping of batteries as OEMs continue to back off EV production. The US government reaction to Dumping is usually increased tariffs, so that might not actually help supply.

[@gdf12349]

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

[@markplott4820]

over 50% more cost Reductions.

[@Starship007]

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

Hello from Azerbaijan. Thank you..❤❤❤

[@avgjoe5969]

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).

[@Nphen]

There simply is not the labor to complete these projects in the places Elon is doing them. Sparks Nevada. Go look for the nearest housing development. It's in the California mountains, some 80+ miles away. There are labor shortages nationally, as Boomers die & retire, and front line workers die or become disabled from the leaked bioweapon. All the hopes & dreams for the Cybertruck were based upon supply chains, labor pools, and geopolitical forces which have since taken a hard turn against what Tesla is trying to do. The US does have national labs & materials research institutes, but that work isn't going to help Tesla with their specific problems. Everything is getting "enshitified" (see Cory Doctorow) even Tesla, it seems.

[@jonpower0]

When the EV is using regenerative braking, surely that is switching the cell back to charging? Does that affect the number of charge cycles for the cell significantly? That is, if the EV is often switching from discharging to temporarily charging in a journey, is it shortening the battery life, or does the battery management system store the regen elsewhere and then use that first?

[@MaykThewessen]

He mixed up cathode and anode - Anode is negative terminal and uses Copper current collector - Cathode is positive terminal and uses Aluminium current collector So the Cybertruck 4680 cell with the small top connector is the (+) terminal The flat bottom is (-) terminal “The anode (or negative electrode) in Lithium-ion battery is typically made up of Graphite, coated on Copper Foil. Graphite is a crystalline solid with a black/grey color and a metallic sheen.”

[@robertgardner-x7y]

The 4680 batteries have NO Lithium metal. Panasonic replaced it with aluminum foil (jelly roll).

[@sreesub]

Do we still have density numbers for CT battery? or just that its more "dense" than one in MY which was 244 wh/kg.

[@TheKevlar]

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...

[@donovanSMMsvlog1583]

I just want 4680 to be available so I can buy them. I would even buy a Chinese version if I could not find a Korean or Japanese. It is the size with the possibility for a stronger cell with more capacity that is interesting. Not the Tesla branding or their version of the tech.

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...

[@syspowertools3372]

Battery day didn't have 500wh/kg on the 4680 road map. As for this VS the competition, GM has pouch cells which are higher gravemetric energy density but way lower volumetric. Not to mention cycle life, degredation, and temperature performance. Rivian should beat Tesla here, but use high cobalt ammounts and a larger pack on a smaller truck. Their range should be better. Tesla is apparently using dry electrolytes which makes this effectively a solid state Battery and thus LFP or greater cycle life and degredation performance and un matched temperature performance. We'll have to see though how real world long term testing goes.

[@squee8174]

It's a theory

[@eugeniustheodidactus8890]

Both the copper and aluminum rolls go into the can ?

[@blueskyresearch6701]

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

[@pritambissonauth2181]

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

[@AntonioDiNunnoEVS]

Cell level, no. module level, maybe. pack level, certainly

[@rmkkkk]

Sandy! Please teardown and evaluate byd blade batteries

[@lab.growth]

Awesome! Amazing job as always. Thanks for sharing!

[@rosnow]

Is Sandy wearing a Doxa watch?

[@Du.L]

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