Such a cool video! Can't wait to see the Cyber Truck in your shop!

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.

Is it just me or is Cory getting in better shape each episode?

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.

Could you put some of the cells into a cell tester, and run cycles, see how they perform and age?:)

Great stuff. CT scans were cool and really helpful to see how it's put together.

Thank you folks, wonderful insight. Seen a few 4680 cell breakdown/teardown videos so far, this one is the perfect blend of technical details and practical implications

This is where Munro (and Antonio) excel in their technical knowledge, presentation, and content. This matters to me, and I appreciate it.

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!

I was curious to see this video after you mentioned it at Fully Charged LIVE. Your description is very informative! I have to say that building these cells seems like a more complicated process than I had imagined.
