They have ordered a cell from Munroe to test the latest cells, as the one they tested was from Kato road many months back and not from Texas.

I really love these breakdowns and analysis so much. As a person with little knowledge and experience though, I miss Sandy coming in and telling me how this compares to other companies, where this puts Tesla, how relatively advanced the tech and techniques are, the pros and cons, what it says about the future, and generally just converting this data into useable information for a normie like me. These are enjoyable even though it feels more like a munro ad selling the reports.

@@culdeus9559 Exactly! I like having the expert to go over the details, then having someone (Usually its Sandy) to translate that into something a dummy like me can take away. Otherwise it is just technical speak for a very small group of people to really appreciate. Maybe it doesn't have to be Sandy, and maybe Munro doesn't really care about informing the general public about what is going on enough to spend the time and energy to do it for every single video, but from what I am understanding, Tesla is pulling off incredible feats of the future that I am excited about. It is hard to share that excitement with others who don't particularly know about it or care, when I can only share technical jargon videos with friends and family that they watch and just go "okay....?"

How "explosive" or volatile is the 4680? Since you guys have been taking so many safety precautions, it would be interesting to see some real destructive testing. Could use cells that are slightly damaged. Fire/heat test, nail test, water test, overload test, charge/discharge test, crush test(under hydraulic press), bullet test, freeze test, and throw-it-at-a-cybertruck test.

A minor point on terminology. According the "The Limiting Factor" channel (and an internet search confirms this), the term "tab" refers to a *separate strip of metal* that is welded to provide connectivity. In the 4680 battery, the tab-like flaps are not separate pieces of metal that have been welded to the jelly roll, but rather are part of the jelly roll's metal backing itself, and a laser was used to cut the flap shapes. Hence, it is correct to refer to the 4680 being "tabless" rather than "multi-tab". I don't come from a battery background, but I *assume* a multi-tab design would provide similar electrical characteristics to a tabless design. I also *assume* that using a laser to cut tab-like flaps into the jelly roll's metal backing offers advantages over welding multiple tabs to the jelly roll's backing, such as perhaps it is cheaper, faster, or more reliable.
@joansparky4439
@joansparky4439 Жыл бұрын
a tab is a piece that sticks out.. just like browser tabs That for economies of manufacturing reasons in roll-to-roll production for efficiency purposes they spot/laser/etc. well extra strips ONTO the strips that form the rolls is not what makes them tabs. And when the tabs run for the whole length of one side of a strip they still are called tabs and it doesn't become tab-less. I also doubt that the cut ins for both the copper and aluminium base material have been done by laser.. a simple cut/shear wheel running over one side in the roll-to-roll process would do just fine.

Just a bit of advice for cutting open the individual batteries: Chuck the battery up in a lathe and mount a Dremel tool on the tool post. Using a very thin abrasive cutting disk or one of the serrated metal cutting disks, you should be able to use the cross slide to slowly feed the running dremel tool's cutting disk (with the lathe also running, but at very low rpm, 5-20 rpm) into the body of the battery. It's a nice way to precisely control the cutting of thin metals, especially those prone to tearing. I prefer the abrasive disks for this, but for your purposes, it might be easier to control the heat generated with a serrated metal cutting disk than with an abrasive disk. Seriously though, this is great for all kinds of cylindrical/conical/spherical (and anything in between) objects with thin walls (Stainless, Carbon fiber, whatever) as long as the part can be held in the chuck, it works great!

Unfortunately there are multiple sizes of Pepsi can, so it doesn't help much. The dimensions are right in the name... got a ruler? The 355 ml (12 oz) cans in my refrigerator are 66 mm in diameter and 123 mm tall, so the 46x80 mm cells are about two-thirds as big in each dimension. The 4680 would ideally be a 133 ml (4.5 oz)... so even smaller than an 8 oz can but I'm not really familiar with that size.

The point is, the short electrical path, up/ down to the tabs rather than along the whole length, reduces resistance, which normally causes heat. Therefore there's less, if any heat produced in the first place. Heat being energy, now not wasted the cell becomes more efficient. Implications for:- Efficiency of the cell (and pack). Heat stress reduction in the cathode / anode, improving longevity. Even temperature through the pack and reduced pack cooling required. Quite possibly faster charging (reduced throttling) ... As for the tabs, it's a conductor, normally electrical, but of heat if needed.

Now if only it were able to offer cars 54% more range as promised. For now, the Model Y gets LESS range than with 3rd party 2170s. If the cell doesn't have significant advantage beyond theoretical cost (their 2170s never seemed worth expanding as they just imported whatever they could get their hands on, and all seemed cheaper and better than Giga Nevada cells), 4680 can't be used for Plaid+ and Roadster and be decently usable cars with the promised specs. No-one promised Roadster would be LIGHT, but with 200 kwh of these cells, that's already 720 kg of cells, likely 1000 kg for a pack all welded up, and only if record breaking for gross/net energy density. 54% more range on the Plaid would simple mean 50% more weight in the cells. Can the pack overheid be trimmed to compensate? Not so sure judging from Model Y being near identical weight for the 4680 but down on capacity and range, at least for now. Semi relies A LOT on energy density to get huge range and not ruin payload. Cyber with 500 mile range needs a 180-210 kWh pack as well. Or will they have a new process to make the steel exoskeleton end up super slick for aero? Worth developing for millions of trucks I guess, but Tesla tend to stumble a lot when innovating.

pricey to make but an improvement from 2170/1865. then again, consider that past months was the first time in Tesla's history they weren't battery constrained despite the highest production numbers yet. It happened due to LFP batteries. I reckon, Model 3/Y Long Ranges will transition to LFP once the Semi/CT ramps so that these large vehicles get all the nickel based batteries.

The thing is: they call it tabless because a tab is normally not the foil of the anode/cathode, but a small piece of metal welded to the anode/cathode. They cut the electrode and fold it over, and then collect it with this copper piece, which one could call the "tab"

The original design tesla showed on battery day did not have any welds to the jelly roll terminals instead they just used pressure against the end caps to provide thermal and electrical connection. I was surprising that that pressure contact alone was going to be good enough when those cells are subject to vibration and thermal cycling and contact corrosion and resistance heating inside the cell. Those flower petal end terminals with the roll tabs welded to them solve the terminal corrosion and resistive heating concern and they also act as a heat spreader so they must have found that pressure alone was not going to be good enough - and it also helps explain why it has taken longer than expected for the 4860 to reach production as they were supposed to be switching over much sooner than they have done. The new design seems very good.

Lucky you - the gigacastings are writeoffs if damaged. The cells are impossible to salvage, which makes cash recovery by insurance companies very poor -- watch for higher insurance rates.

I was split between this decision myself and then came to the conclusion that Cutting Edge" isn't always the best place to be. They have a lot of manufacturing processes to experiment with and work out and I needed a stable reliable car, even if they can fix most things with a software update. The 2170 is proven tech.

What is the capacity of a cell in Amp hours or multiplied with nominal voltage: the capacity in Watt hours? Did you do measurements at cell level?
@Cloxxki
@Cloxxki Жыл бұрын
Initial reports are that it's still in the 270 Wh/kg ballpark, perhaps on the higher side of that. Explains why the "OMG it's almost structural" Model Y is just barely lighter than the previous version, while having a lot less energy capacity and range. It it's 5.5 times larder than a 2170. If this costs less than 5.5x as much to product, they can try to make it worth there while NOT to simply buy LG cells like they have been. It gets interesting when they can make one of these for the price of 3x 2170, I guess. Apparently it can handle the energy demand cycles for a Model Y. I wonder whether it's ready to do the same for the Plaid. However, from the looks of things, it's NOT ready to bring Plaid and Roadster, even Semi and Cyber, the capacity they need, by lack of energy density.

I personally don't like amp hours because it implies that all voltage are the same. While many are, I don't like the premise that leads to the use of amp hours. YMMV.

@@tesla_tap Tesla (Maxwell) dry process is for electrode manufacturing (no solvent to evaporate). Cells still have electrolyte that ions travel through. They only add enough to saturate the separator, no extra to slosh. A solid electrolyte cell would be totally dry.
