@ManishEarth can Fe exist in +1 oxidation state?

@energy hmm, tough question. Usually my advice is to just post it and see if it gets closed (at which point we can try to improve from there)

In this case I suggest explaining the working of the battery and asking which parts of it are new tech. Bit localised, but it sounds interesting.

@user dunno. I don't know of any case where it does.

@Aesin we had a good laugh over that one in the TL. Until it got ugly.
