There is a positive electrode (cathode) that is usually made up of a metal oxide. There is a negative electrode (anode) that is typically a form of carbon graphite material. Between the electrodes is a liquid organic solvent electrolyte that allows the transfer of ions, and an ion-permeable plastic separator.
When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place. As current flows, electrons from the circuit and cations from the electrolytic solution in the device move towards the cathode.
