Unfortunately this is ambiguous. They don't specify conventional current, or real current.

Then he is defining current as the conventional, or opposite of the electron current. In that case the the ecurrent flows into the positive electrode of the CS cell so it is the anode, and the negative electrode is the cathode. I did not realize the definitions switched on a battery depending on if it is charging or discharging. Learn something new every day.
