Releasing Tesla battery video.

Schoopage sometimes referred to as endspray in the UK capacitor manufacturing sector. At our factory on the East coast in Great Yarmouth we spray Zinc wire on to the ends of the capacitor windings, sometimes tin zinc, the latter being better for solderability and less chance of latent heat damage to the dielectric materials. The metal wire is sprayed used an arc spray gun. Thin dielectric materials (e.g. 3µm thickness metallised polyprpylene capacitor films) are more challenging to spray, as the particle size of the metal being deposited is crucial, to small and the particles can penetrate too far into the winding and cause short circuits, too large and it folds the edge of the film over causing a high resistance connection, not ideal on the ends of the windings where the current densities are the greatest. To overcome this capacitor film metallisers can offer a wave cut edge to the film, rather than the traditional parallel edge. Such windings can be oil impregnated after spraying, but this involves use of vacuum impregnation equipment and hot oil to lower its viscosity.

I think if it creates a dialog on the subject it's a good thing.

Yes! I think you're right about the "how". Laser etching of a pattern of tabs to let it fold / interleave / smoosh down neatly is a technology we just didn't have not so long ago. Very simple, enabled only recently by new technologies with many devils in the details I bet, clear advantages, very easy to verify if a competitor steals the idea and uses it without permission... /Man/ what a good patent this must be!

I'm quite happy being independent. I get the feeling that Mr Musk is quite demanding to work for.

I just seen a picture of what they are calling teslas new tabless battery. I have to say you were very close to what they did. Your idea may even be better. It appeared to me that the plate was just extended out past the separator. then cut to allow it to lay somewhat flat after folding it down. One thing about your idea of using the spray on layer is you could possibly affix the contacts right in with it as it is applied.

Was it supposed to be posted in here? I don't see it. Never mind, I found it on the main page.

Jeff Larson

It is good speculation, perhaps you should have tried to patent it yourself first. Other tech sites are focusing on the tabless construction, lack of cobalt, and building the batteries into the fabric of the vehicle somehow.

AlfaGuy

Nothing wrong with it. Don't hesitate to release it.

Rocco Rizzo

Even as we discuss this, a helicopter has been fueled and is en route to Clive's house. Mr Musk will try to seduce you, please don't go !

Yes release it nothing wrong with not making a correct assumption. Good to show mistakes can be made then learnt from

At the very least, i learned how those capacitors are made.

Who knows... Someone may be working on this end termination technology already.

Big Clive

Right or wrong it's an interesting video and should get the attention of people following the announcements.

Matt Tester

Why is it so obvious you are wrong with that, what did I miss? And progress was never made by people not thinking and not asking ...
