I see I'm not alone in downvoting you. Personally, this is because you're just being contrarian and not really adding to the discussion. Deflected electrodes, insufficient insulation tape, and high welding burrs are absolutely fine explanations for what happened here. As someone who works with batteries, that would tell me everything I wanted to know. In this case, the "root causes" are not terribly interesting. The cause for the high weld burrs is that the settings on the welding machines were set wrong. If they said "the settings on the welding machines were set wrong", or the root cause for that ("our battery technicians were incorrectly trained"), that would have been useless. In contrast, this is a fantastic explanation, presented in a very clear way. If I was running a battery fab, I'd be able to check for these problems in 20 minutes. Further in the favor of Samsung is that battery fabs are some of the most opaque places in the world. They never release any information of any value whatsoever to the outside, and there are only a handful in the world. For Samsung to release something like this so candidly is absolutely unprecedented in the world of batteries; I was shocked when I saw the post.
