Inzuzo enkulu ye-organometallic film capacitors kukuba i-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-self-capacitors, eyenza ukuba enye yee-capacitors ezikhula ngokukhawuleza namhlanje.

Kukho iindlela ezimbini ezahlukeneyo zokuziphilisa kwe-capacitors yefilimu enesinyithi: enye ikhupha ukuziphilisa;enye i-electrochemical self- healing.Eyangaphambili yenzeke kumbane ophezulu, ngoko ikwabizwa ngokuba yi-high-voltage self-self-healing;kuba le yamva iyenzeka kumbane ophantsi kakhulu, ihlala ibizwa ngokuba yi-low-voltage self-healing.

Ukukhupha Ukuziphilisa

Ukubonisa indlela yokukhupha ukuziphilisa, cinga ukuba kukho isiphene kwifilimu yezinto eziphilayo phakathi kwee-electrode ezimbini ze-metalized kunye nokumelana no-R. Ngokuxhomekeke kwimeko yesiphako, ingaba yintsimbi, i-semiconductor okanye kakubi. i-insulated defect.Ngokucacileyo, xa isiphene singomnye wangaphambili, i-capacitor iya kube izikhuphile kumbane ophantsi.Kuphela kwimeko yokugqibela into ebizwa ngokuba yi-high voltage discharge iziphilise ngokwayo.

Inkqubo yokukhupha ukuziphilisa kukuba ngokukhawuleza emva kokufaka i-voltage V kwi-capacitor yefilimu enesinyithi, i-ohmic yangoku I = V / R idlula kwisiphene.Ngoko ke, uxinaniso lwangoku J=V/Rπr2 luhamba nge-electrode enesinyithi, oko kukuthi, indawo ekufutshane nesiphene (incinci i-r) kwaye ukuphakama kwayo kwangoku kungaphakathi kwe-electrode ye-metalized.Ngenxa yokushisa kwe-Joule okubangelwa ukusetyenziswa kwamandla e-defect W = (V2 / R) r, ukuchasana kwe-R ye-semiconductor okanye i-insulating defect iyancipha ngokukhawuleza.Ngoko ke, i-I yangoku kunye nokusetyenziswa kwamandla W kwanda ngokukhawuleza, ngenxa yoko, ukuxinwa kwangoku J1 = J = V / πr12 kuphakama ngokukhawuleza kummandla apho i-electrode yensimbi isondele kakhulu kwisiphene, kwaye ukushisa kwayo kwe-Joule kunokunyibilikisa i-metalized. umaleko kummandla, obangela ukuba i-arc phakathi kwee-electrode ibhabhe apha.I-arc ikhawuleza iphuphe kwaye ilahle isinyithi esinyibilikisiweyo, yenze indawo yodwa ekhuselweyo engenamaleko esinyithi.I-arc icinyiwe kwaye ukuziphilisa kufezekiswa.

Ngenxa yobushushu be-Joule kunye ne-arc eveliswe kwinkqubo yokuziphilisa, i-dielectric ejikeleze isiphene kunye nommandla wokuzihlukanisa we-dielectric surface iyonakaliswa ngokuqinisekileyo ngumonakalo obushushu kunye nombane, kwaye ngoko ke ukubola kweekhemikhali, i-gasification kunye ne-carbonization, kunye nokuba. kwenzeka umonakalo oomatshini.

Ukusuka apha ngasentla, ukuze kuphunyezwe ukuziphilisa ngokugqibeleleyo, kuyafuneka ukuba kuqinisekiswe indawo efanelekileyo yendawo ejikeleze isiphene, ngoko uyilo lwecapacitor yefilim enyibilikisiweyo kufuneka iphuculwe ukuze kuphunyezwe indawo ephakathi ejikeleze umhlaba. isiphene, ubukhulu obufanelekileyo bomaleko owenziwe ngesinyithi, indawo engqongileyo ye-hermetic, kunye nombane ongundoqo ofanelekileyo kunye nomthamo.Okubizwa ngokuba yi-dicharge egqibeleleyo yokuziphilisa: ixesha lokuziphilisa lifutshane kakhulu, amandla okuziphilisa amancinci, ukuhlukaniswa okugqwesileyo kweziphene, akukho monakalo kwi-dielectric ejikelezayo.Ukuze kuphunyezwe ukuziphilisa kakuhle, iimolekyuli zefilimu ephilayo kufuneka ziqulathe umlinganiselo ophantsi wekhabhoni ukuya kwiathomu ye-hydrogen kunye nomlinganiselo ophakathi weoksijini, ukwenzela ukuba xa ukubola kweemolekyuli zefilimu kwenzeka ekuzikhupheni kokuziphilisa, hayi. ikhabhoni iveliswa kwaye akukho ukufakwa kwekhabhoni okwenzekayo ukuphepha ukubunjwa kweendlela ezintsha zokuqhuba, kodwa kunokuba i-CO2, i-CO, i-CH4, i-C2H2 kunye nezinye iigesi ziveliswa ukucima i-arc ngokunyuka okubukhali kwegesi.
Ukuze kuqinisekiswe ukuba i-media ejikeleze isiphene ayibonakalisi xa uziphilisa, amandla okuziphilisa akufanele abe mkhulu kakhulu, kodwa angabi ncinane kakhulu, ukwenzela ukususa i-metallization layer ejikeleze isiphene, ukubunjwa kwe-insulation. (ukuchasana okuphezulu) indawo, isiphene siya kuba sodwa, ukufezekisa ukuziphilisa.Ngokucacileyo, amandla okuziphilisa afunekayo anxulumene ngokusondeleyo nentsimbi yomaleko we-metallization, ubukhulu, kunye nokusingqongileyo.Ngoko ke, ukuze kuncitshiswe amandla okuziphilisa kunye nokufezekisa ukuziphilisa okulungileyo, i-metallization yefilimu eziphilayo kunye nentsimbi ephantsi yokunyibilika iyenziwa.Ukongezelela, i-metallization layer akufanele ilingane kwaye incinci, ngakumbi ukuphepha imikrwelo, kungenjalo. , indawo yokwahlukaniswa kwe-insulation iya kuba njengesebe kwaye iyasilela ukufezekisa ukuziphilisa okulungileyo.I-CRE capacitors zonke zisebenzisa iifilimu eziqhelekileyo, kwaye kwangaxeshanye ulawulo olungqongqo lokuhlola izinto ezingenayo, luvalela iifilimu ezineziphene emnyango, ukwenzela ukuba umgangatho weefilimu ze-capacitor uqinisekiswe ngokupheleleyo.

Ukongeza ekuzikhupheni ukuziphilisa, kukho enye, eyi-electrochemical self-healing.Makhe sixoxe ngale ndlela kwinqaku elilandelayo.
