A realistic battery prototype lab bench. Centered is a clear electrochemical cell with blue copper solution, two wires, and a thin copper-coated tray that looks patchy. A tablet beside it shows short readable text: “Copper recovery test”, “0.50 A”, “900 s”, “thin deposit”. A sticky note says: “coulombs, not vibes”.

Thin plating

I’m helping Nina in the battery lab. A copper recovery test was supposed to plate neatly, but the tray came out thin and patchy. The tablet has one annoyed sticky note: coulombs, not vibes.
