Source sentences:
text: Due to their self-healing properties (the non-solid electrolyte can deliver oxygen to form new oxide layer in weak areas of the dielectric), the dielectric thickness can be formed with much lower safety margins and consequently with much thinner dielectric than for solid types, resulting in a higher CV value per volume unit.
text: Otherwise, the electrolyte has to deliver the oxygen for self-healing processes, and water is the best chemical substance to do that.
text: One problem of the forming or self-healing processes in non-solid aluminum electrolytics is that of corrosion, the electrolyte having to deliver enough oxygen to generate the oxide layer, with water, corrosive of aluminum, being the most efficient way.
text: This leakage current in solid electrolyte capacitors cannot be reduced by "healing" in the sense of generating new oxide because under normal conditions solid electrolytes are unable to deliver oxygen for forming processes.
text: However, liquid electrolyte can flow to the faulty spot and can deliver oxygen to build up new dielectric oxide.
text: Advantage of this construction is that the liquid electrolyte in operation delivers the oxygen which is necessary for self-healing of the dielectric layer in the presence of any small defects.
