It's electrolytic corrosion, from stray current in the presence of an electrolyte - eliquid vapor condensed on the metal surfaces, then current passing thru it. Loads of different metals accelerates it, add in some aluminum somewhere (a horrible metal, to be avoided at all costs*) and bingo! Ya got dead electrons.
Well, I spent years in marine engineering where we had plenty of electrolytic corrosion like this, and nobody ever came up with such a great name for that gunk. It's oxides of the various metals plus residues from the liquid of course, but what the hell, dead electrons sounds way cooler. I like it.
What the ecig really needs is a zinc anode fitted in there somewhere, a 2 kilo one should fix it.
* Find an aluminum ladder that's not anodised, put your hands on it. They come off black with filth even though the metal is bright and looks clean. Ali corrodes like hell and melts away in the sun. Don't take it anywhere near the sea - or even sea air. In fact don't take it anywhere. Give me 70-30 cupronickel or 316 stainless any day
