Kwinqaku elingaphambili sigxile kwenye yeendlela ezimbini ezahlukeneyo zokuziphilisa kwi-capacitors zefilimu ezenziwe ngesinyithi: ukuziphilisa ngokukhupha, okwaziwa ngokuba yi-high-voltage self-healing. Kweli nqaku siza kujonga olunye uhlobo lokuziphilisa, i-electrochemical self-healing, ekwabizwa ngokuba yi-low-voltage self-healing.

Ukuziphilisa nge-Electrochemical

Ukuziphilisa okunjalo kudla ngokuvela kwii-capacitors zefilimu ezenziwe nge-aluminium metalised kwi-voltage ephantsi. Indlela yokusebenza kokuziphilisa yile ilandelayo: ukuba kukho isiphene kwifilimu ye-dielectric ye-capacitor yefilimu eyenziwe nge-metalised, emva kokuba i-voltage yongezwe kwi-capacitor (nokuba i-voltage iphantsi kakhulu), kuya kubakho umsinga omkhulu wokuvuza ngesiphene, obonakaliswa njengoko ukumelana nobushushu be-capacitor kuphantsi kakhulu kunexabiso elichazwe kwiimeko zobugcisa. Ngokucacileyo, kukho imisinga ye-ionic kwaye mhlawumbi imisinga ye-elektroniki kwi-leakage current. Ngenxa yokuba zonke iintlobo zeefilimu ze-organic zinezinga elithile lokufunxwa kwamanzi (0.01% ukuya kwi-0.4%) kwaye ngenxa yokuba ii-capacitors zinokuba phantsi komswakama ngexesha lokwenziwa kwazo, ukugcinwa nokusetyenziswa kwazo, inxalenye ebalulekileyo yomsinga we-ionic iya kuba yimisinga ye-O2- kunye ne-H-ion ebangelwa ngamanzi asetyenziswa nge-electrolys. Emva kokuba i-O2-ion ifikelele kwi-AL metalised anode, idibana ne-AL ukwenza i-AL2O3, ethi kancinci kancinci yenze umaleko wokufaka i-AL2O3 ngokuhamba kwexesha ukuze igqume kwaye ihlukanise isiphene, ngaloo ndlela inyusa ukumelana kokufaka i-insulation kwe-capacitor kwaye ifikelele ekuzinyangeni.

Kuyacaca ukuba kufuneka amandla athile ukuze kugqitywe ukuziphilisa kwe-capacitor yefilimu ye-metalised organic. Kukho imithombo emibini yamandla, enye ivela kumbane kwaye enye ivela kwi-oxidation kunye ne-nitriding exothermic reaction yesinyithi kwicandelo le-blem, amandla afunekayo ukuze azinyange adla ngokubizwa ngokuba ngamandla okuziphilisa.

 
Ukuziphilisa lolona phawu lubalulekileyo lwee-capacitors zefilimu ezenziwe ngesinyithi kwaye iingenelo ezizisayo zinkulu. Nangona kunjalo, kukho ezinye iingxaki, njengokuncipha kancinci kancinci kwamandla e-capacitor esetyenzisiweyo. Ukuba amandla asebenza ngokuziphilisa kakhulu, kuya kukhokelela ekunciphiseni okukhulu kwamandla ayo kunye nokumelana nobushushu, ukwanda okukhulu kwe-angle yokulahleka kunye nokusilela ngokukhawuleza kwe-capacitor.

Ukuba unolwazi ngezinye iinkalo zeempawu zokuziphilisa zee-capacitors zefilimu ezenziwe ngesinyithi, nceda uxoxe ngazo nathi.
