Qhov txiaj ntsig loj tshaj plaws ntawm cov capacitors zaj duab xis organometallic yog tias lawv kho tus kheej, uas ua rau cov capacitors no yog ib qho ntawm cov capacitors loj hlob sai tshaj plaws niaj hnub no.

Muaj ob txoj kev sib txawv rau kev kho tus kheej ntawm cov capacitors zaj duab xis hlau: ib qho yog kev tso tawm tus kheej kho; qhov thib ob yog electrochemical tus kheej kho. Tus thawj tshwm sim ntawm qhov hluav taws xob siab dua, yog li nws kuj raug xa mus rau qhov kev kho tus kheej siab-voltage; vim tias qhov kawg kuj tshwm sim ntawm qhov hluav taws xob qis heev, nws feem ntau raug xa mus rau qhov kev kho tus kheej qis-voltage.

Kev Kho Tus Kheej

Yuav piav qhia txog txoj kev kho tus kheej ntawm kev tso tawm, xav tias muaj qhov tsis zoo hauv zaj duab xis organic ntawm ob lub electrodes hlau nrog qhov tsis kam ntawm R. Nyob ntawm qhov xwm txheej ntawm qhov tsis zoo, nws yuav yog qhov tsis zoo ntawm hlau, semiconductor lossis qhov tsis zoo ntawm insulated. Nws yog qhov tseeb, thaum qhov tsis zoo yog ib qho ntawm cov thawj, lub capacitor yuav tau tso tawm nws tus kheej ntawm qhov hluav taws xob qis. Nws tsuas yog nyob rau hauv qhov xwm txheej tom kawg uas qhov hu ua kev tso tawm hluav taws xob siab kho nws tus kheej.

Cov txheej txheem ntawm kev tso tawm tus kheej kho yog tias tam sim ntawd tom qab siv lub zog V rau lub capacitor zaj duab xis hlau, lub zog ohmic I = V / R hla dhau qhov tsis zoo. Yog li ntawd, qhov ceev tam sim no J = V / Rπr2 ntws los ntawm lub electrode hlau, piv txwv li, qhov ze dua rau qhov tsis zoo (qhov me dua r yog) thiab qhov siab dua nws qhov ceev tam sim no nyob hauv lub electrode hlau. Vim yog Joule cua sov los ntawm qhov tsis zoo siv hluav taws xob W = (V2 / R) r, qhov tsis kam R ntawm lub semiconductor lossis insulating tsis zoo txo ​​​​​​qhov exponential. Yog li ntawd, tam sim no I thiab kev siv hluav taws xob W nce sai, yog li ntawd, qhov ceev tam sim no J1 = J = V / πr12 nce siab hauv thaj chaw uas lub electrode hlau nyob ze rau qhov tsis zoo, thiab nws cov cua sov Joule tuaj yeem yaj cov txheej hlau hauv thaj chaw, ua rau lub arc ntawm cov electrodes ya ntawm no. Lub arc sai sai evaporates thiab pov tseg cov hlau molten, tsim ib qho chaw cais tawm tsis muaj txheej hlau. Lub arc raug tua thiab kev kho tus kheej tau ua tiav.

Vim yog Joule cua sov thiab arc tsim tawm hauv cov txheej txheem tso tawm tus kheej kho, lub dielectric nyob ib puag ncig qhov tsis xws luag thiab thaj chaw cais tawm ntawm qhov chaw dielectric yog qhov tsis zoo los ntawm kev puas tsuaj thermal thiab hluav taws xob, thiab yog li ntawd cov tshuaj lom neeg decomposition, gasification thiab carbonization, thiab txawm tias kev puas tsuaj rau lub tshuab tshwm sim.

Los ntawm cov saum toj no, txhawm rau kom ua tiav qhov kev tso tawm zoo meej, nws yog qhov tsim nyog los xyuas kom meej tias muaj ib puag ncig hauv zos nyob ib puag ncig qhov tsis zoo, yog li tsim cov khoom siv hluav taws xob organic zaj duab xis capacitor yuav tsum tau ua kom zoo tshaj plaws kom ua tiav qhov nruab nrab tsim nyog nyob ib puag ncig qhov tsis zoo, qhov tuab ntawm cov txheej hlau, ib puag ncig hermetic, thiab lub zog hluav taws xob thiab lub peev xwm tsim nyog. Qhov hu ua kev tso tawm zoo meej tus kheej kho yog: lub sijhawm kho tus kheej luv heev, lub zog kho tus kheej me me, kev rho tawm zoo heev ntawm qhov tsis zoo, tsis muaj kev puas tsuaj rau cov dielectric nyob ib puag ncig. Txhawm rau kom ua tiav qhov kev kho tus kheej zoo, cov molecules ntawm cov zaj duab xis organic yuav tsum muaj qhov sib piv qis ntawm cov pa roj carbon rau hydrogen atoms thiab cov pa oxygen nruab nrab, yog li thaum lub sijhawm rhuav tshem cov zaj duab xis tshwm sim hauv qhov kev tso tawm tus kheej kho, tsis muaj carbon tsim thiab tsis muaj carbon deposition tshwm sim kom tsis txhob muaj cov kab ke tshiab, tab sis theej CO2, CO, CH4, C2H2 thiab lwm yam roj tau tsim los tua lub arc nrog kev nce siab hauv roj.
Yuav kom ntseeg tau tias cov xov xwm nyob ib puag ncig qhov tsis zoo tsis raug puas tsuaj thaum kho tus kheej, lub zog kho tus kheej yuav tsum tsis txhob loj dhau, tab sis kuj tsis txhob me dhau, txhawm rau tshem tawm cov txheej metallization nyob ib puag ncig qhov tsis zoo, tsim cov rwb thaiv tsev (siab tsis kam) thaj tsam, qhov tsis zoo yuav raug cais tawm, kom ua tiav kev kho tus kheej. Nws yog qhov tseeb, lub zog kho tus kheej xav tau yog ze rau cov hlau ntawm cov txheej metallization, tuab, thiab ib puag ncig. Yog li ntawd, txhawm rau kom txo qhov zog kho tus kheej thiab ua tiav kev kho tus kheej zoo, metallization ntawm cov yeeb yaj kiab organic nrog cov hlau melting qis yog ua tiav. Tsis tas li ntawd, cov txheej metallization yuav tsum tsis txhob tuab thiab nyias tsis sib xws, tshwj xeeb tshaj yog kom tsis txhob khawb, txwv tsis pub, thaj chaw cais rwb thaiv tsev yuav dhau los ua ceg thiab ua tsis tiav kev kho tus kheej zoo. CRE capacitors txhua tus siv cov yeeb yaj kiab tsis tu ncua, thiab tib lub sijhawm nruj tswj cov khoom siv tshuaj xyuas, thaiv cov yeeb yaj kiab tsis zoo ntawm lub qhov rooj, yog li qhov zoo ntawm cov yeeb yaj kiab capacitor tau lees paub tag nrho.

Ntxiv rau qhov kev kho tus kheej ntawm cov pa roj tawm, muaj lwm qhov, uas yog kev kho tus kheej ntawm cov hluav taws xob. Cia peb tham txog txoj hauv kev no hauv tsab xov xwm tom ntej.
