For example, in a typical Lithium ion cobalt oxide battery, graphite is the – electrode and LCO is the + electrode at all times. When discharging a battery, the cathode is the positive electrode, at which electrochemical reduction takes place.
Customer ServiceThe cathode is the positive electrode, where reduction (gain of electrons) occurs, while the anode is the negative electrode, where oxidation (loss of electrons) takes place. During the charging process in a battery, electrons flow from the cathode to the anode, storing energy that can later be used to power devices
