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

To save everyone the hassle of filling out the "get the report" form:

FWIW I found the report's summary (a few days ago when this was also discussed) essential for clarifying for me what the linked "article" was talking about regarding "anode overhang" and "edge alignment".

To summarize it myself, the battery is cylindrically wrapped sheets of anode/cathode material, and you want the top edge to have a straight line consistently having the anode layers (|) sticking out beyond the cathode layers ()

edit: Welp, the unicode I illustrated with got stripped out; so trying again with pipes

    anode
     cathode
      a a
       c c

The pics with red and blue dots didn't immediately make this obvious to me, but made sense once I understood the "overhang" meaning.
