With the recent media activity surrounding Elon Musk's announcement of the new Tesla tabless battery technology, I thought I'd speculate on what they are going to be doing.
I made this video before seeing their current tech (pleated copper foil at the negative end).
The potential for this is cheaper cells that have a higher current capability and better heat dissipation.
If they manage to make a solid core with schoopage contacts then it opens up the possibility of cells that resemble resin dipped metallised film capacitors.
Here's a very interesting page on Wikipedia that shows the capacitor version of the technology:-
https://en.wikipedia.org/wiki/Film_capacitor
Other possibilities might be a mesh or patterned schoopage to allow penetration and flow of electrolyte.

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.

OxidAtion occurs at the Anode,
ReduCtion occurs at the Cathode.
That is the easy way to tell them apart.
I think that wikipedia page was the start of one heck of a rabbit hole to dive into… I wonder if anybody is using that "stacked" design for batteries rather than the "rolled" approach that you describe?
I'm just curious cuz why couldn't you just make this like a Transformer of sorts just saying in style of construction but since it's got to be an integral part of the chassis of course you would have to Custom Design its shape but I'm not a battery engineer and I don't know if that would be even possible do… you making a one large battery cell might not produce the same kind of power as multiple battery cells I'm just curious because if it was one large cell like that it would be easier to maintain separation between layers or I would assume could be wrong
Should you have an ( ancient 1960's ) torch that uses a Number 8 ( 3 Volt ) battery ( no longer made ? ) , then a 18650 Li Ion cell will fit just nicely in the 8's plastic outer, stretch the spring a tad and hey presto a working torch ! Also 18650 cells do not leak ( unlike !@**@ nasty horrid alkaline types, which cause all manner of corrosion and caustic slime on your fingers ) QED
I wonder if he will coin the term "Hyper-Schoopage"? I hope so because here's the proof I did it first!
As far as I can tell old Elon's game plan seems to be: Look for an idea from 50-150 years ago, pretend he invented it, and hype the daylights out of it.
Sometimes the hype-train (ah-ha!) comes direct from his 'mind', in which case it's always unworkable fan-bait nonsense. Sometimes the hype-train comes from something one of his engineers dug up, in which case there may be a fighting chance of it not being complete nonsense. Maybe..?
I do find it odd that these cells are made as a roll of separate layers. In my fevered imagination I picture an electrolyte film with a different film deposited on each side. Thinking this through I suppose it would work for a flat layered pack but an additional insulation film would be needed for rolling.
It's not just battery chemists who use that convention. That's the way any chemistry that involves electrons and salt bridges is taught. Confused the h-e-double hockey sticks out of me in high school.
Batteries can short when too much longitudinal pressure is applied… I know lets put them in fast moving vehicles that rarely crash!
Why not just put a capacitor at the positive end of the battery before the cap picking up the voltage and releasing it as needed a through a resistor?
Honestly I think Elon Musk and company came out strong doing something no other corporation was willing to do but I think those times are a changing very quickly. I think Tesla may be a thing of the past sooner then you might think. Something to be said about solid state battery technology that is a couple of years away but very promising. Lithium is very good but better is coming in order to get off the fossil fuel bandwagon. I love gasoline or petrol as some like to call it as much as anyone but there was a need to move past vacuum tubes to solid state and with battery tech moving somewhat fast there will be other techs emerging. Tesla could have been the battery innovator but I have this feeling they are actually falling behind. Let us talk the "Hyper loop" let's not. SpaceX, maybe something but not enough; privatization of space travel might happen in the future but it really takes the peoples money spent wisely to do space travel correctly now and probably well into the future. Valiant effort although. I have been working up some ideas on warp drive on my white board, I will share them soon … 😉 …
Thanks for the "schoop" on how that works!! 😉
now we know the answer is foldage
Could you do a video about Aluminium-Air Battery please
