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!

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.
@joansparky44392 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.

As we see more of the insides of the 4680 cell, I think people are beginning to realize that Tesla has advanced the state of engineering of cylindrical cells. They have reduced the path length of the electrons by a factor of 20 compared to a single tab design and thereby reduced the internal resistance as well. With lower internal resistance comes greater ability to discharge or charge at high rates with much less waste heat generation. I think this is why BMW has switched to 4680 form factor cells for their new EV designs. An engineer finally did the analysis and convinced the management chain that it was a much better design.

Not sure why they wouldn't go with Tesla's design but it kind of shows they did not co-develop it.

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.

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.

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.

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.

Switching gears a bit....any thoughts on doing a performance assessment against other cells? Like a cell showdown of sorts. Cyber cell off :)
@rogerstarkey53902 жыл бұрын
I count (at least) 7 new processes to be perfected in this cell. Not even the "tradition manufacturers" have used them (they possibly still don't use them all?) When they *do* get this right it's going to be transformative . As for the comparison, we already know the previous stripdown used a "lower grade" cathode material (Below the 2170 standard) The jist I got from this is that it's upgraded. Sandy already said they were "surprised" by the performance of this iteration, it was better than expected. . Now consider they gave an indication of the composition, but it isn't absolute cutting edge(?) . That indicates there's a lot more scope for improvement.

I am so fricken impressed by the sheer volume of awesome, innovative genius of Elon Musk's Tesla. Not just the 4680, it's FSD, the GigaPress, the Dojo Super Computer, GigaFactorys, octovalves, and on and on. It's breathtaking to such a degree, I feel fortunate to be alive, as a Computer Scientist, to see all this unfold in real time. Amazing. Inspiring. Historic. Even more so, that it's in a critical, bread-n-butter industry that actually fights innovation.

4680s are not really impressive thus far. Only when they make true to promises other than can size, will it count. Remember the 2170 hype? I do. And I've seen how they followed up. What's different this time? Jus that there is less Panasonic involvement? Energy density is basically the same as Nevada or LG 2170 cells. But Model Y is not seeing benefit from the "structural" design supposed to save weight or bring "54% more range". Not even 1%.

@@Cloxxki I agree but if they can scale up production, the 4680s may become more cost effective as a 21700 could probably be. And that's what it's all about in my opinion.

Looks pretty similar to the one from the Limiting Factor, which indicates that measurements by UCSD could be correct for now. It would be interesting to see if Munro found liquid electrolyte and if the cathode was still made with wet process.

Interestingly, (If I understand the topology you show), that brittle cathode material with a fracture will generally not cause a cell failure since it has the continuous tab construction. So a vertical break doesn't prevent conduction to the edge. A horizontal break would potentially take part of the capacity out but only over the area of the horizontal breakage of the material! So this seems intrinsically more fault tolerant than the tabbed design where a vertical break in the cathode material could open up the conduction path of nearly the entire cell creating a failure (due to the conduction path being mostly horizontal in the jelly roll and only one conduction point out.
