Re: anode once refered to positive terminal not negative, of a battery?

This sounds like either a misunderstanding on your part or, just as likely, a 
slip on the part of someone posting an answer here.

The cathode is indeed the negative electrode, where reduction occurs, and the
anode the positive electrode, where oxidation takes place. If you (like me) 
have had "cation = positive" and "anion = negative" drummed into your head, 
you can remember this by remembering that the cathode is where cations go and
the anode is where anions go, and that opposite charges attract.
