    A post today raised a question about a possible error in the section discussing battery chemistry.

    The actual section in question is this:

    Perhaps the first sentence should be:

    And the second sentence would become:

    What are your thoughts?

    My head hurts. If electrons flow into an electrode, would it not become negative, as in a surplus of electrons? If electrons flow out of an electrode ditto for positive, as in a deficit?

    Sure, electron flow into a positive electrode would make it less positive, not negative, and visa verse (ignoring the completed circuit through the electrolyte). Why would electrons flow into a negative electrode? In order to avoid that confusion, I think "by convention" solves the dilemma. John
