CT scans of 1k lithium-ion batteries show quality risks in inexpensive cells

I wonder if ultrasound techniques might provide an alternative. If it takes 10+ hours to do a CT inspection, as someone pointed out elsewhere (if I understood correctly), then that's a lot of DSP time.

For that matter, jeez, how long does it take to just whip out a Dremel tool and take the battery apart for inspection? I must have misunderstood that comment.

Scan time depends on material composition in the object you're scanning and your requirements for resolution. You can scan a dense steel object overnight to capture micron-level detail, or you can scan a plastic object in a few seconds to search for a known issue like a crack.

Battery scans are very fast; the scans in the report took less than a second. Total cycle time on a Triton CT scanner is under 5 seconds when you account for part handling.
