The electrode can be divided into positive electrode and negative electrode, the positive electrode refers to the end with higher potential, and the negative electrode refers to the end with lower potential. Generally, the positive electrode is the cathode and a reduction reaction occurs when the electrons are obtained, while the negative electrode is the anode and an oxidation reaction occurs when electrons are lost.
