Common failure modes of aluminum electrolytic capacitors are due to chemical reactions between electrodes and electrolyte. From capacitance and weight change data and electron micrographs it is proposed that the attack of anode foil is primarily dissolution of oxide dielectric; that of cathode foil involves metal dissolution with hydrogen evolution.
