The electrolyte volatilizes and condenses in the aperture in anode, then partly hydrolyzes and dewater, then the stress are produced by expansion in this process. The expansion stress is the dominant cause of the graphite anode damage, and the oxidation of the active graphite particles on the anode surface is subsidiary for the anode damage. The measures of prolonging the anode service life are to enhance the quality of the anode such as increasing the forming pressure in the preparation and surface treatment before application.

认为石墨阳极的破损主要是由于石墨阳极中有比较多的孔隙，其中挥发进入石墨阳极表面孔隙的电解质吸水水解、脱水等过程发生膨胀，使周围的石墨颗粒应力不平衡而发生破损；其次是由于石墨阳极孔隙中活性高的石墨颗粒氧化。
