The positive electrode is typically a metal oxide the positive electrode is sometimes called the cathode as it acts as a cathode during discharge. This negative electrode is sometimes called the anode as it acts as an anode during discharge. The negative electrode of a conventional lithium-ion cell is typically graphite, a form of carbon.
