Dab tsi yog capacitive zog cia thiab hom mechanisms yog dab tsi?

Capacitive zog ciayog hais txog cov cuab yeej ntawm kev khaws cov hluav taws xob hluav taws xob uas siv cov capacitors. Capacitive zog cia tau dav siv nyob rau hauv hluav taws xob tsheb, cua thiabphotovoltaic zog cia, lub zog hluav taws xob hluav taws xob kev tswj hwm zoo, cov khoom siv hluav taws xob mem tes, thiab lwm yam.

Raws li qhov sib txawv ntawm lub zog cia mechanisms, capacitive zog cia yuav muab faib ua ob hom hauv qab no:

1. Fais Ob Chav Txheej Capacitance:Hluav taws xob ob txheej txheej capacitance yog ua tiav los ntawm kev taw qhia ntawm cov khoom siv hluav taws xob lossis ions ntawm electrode / kev daws teeb meem, uas ua rau muaj kev sib cav ntawm cov nqi. Rau lub tshuab electrode / kev daws teeb meem, ob txheej txheej yog tsim los ntawm kev sib tshuam ntawm cov khoom siv hluav taws xob thiab cov tshuaj ion-conducting electrolyte. Thaum lub tshuab hluav taws xob tau siv rau ob lub electrodes, anions thiab cations hauv cov tshuaj tsiv mus rau qhov zoo thiab tsis zoo electrodes, feem, tsim ob txheej ntawm electrode nto; Tom qab lub tshuab hluav taws xob raug tshem tawm, qhov zoo thiab qhov tsis zoo ntawm cov electrodes yog nyiam los ntawm cov nqi sib txawv ntawm cov ions hauv cov tshuaj, stabilizing ob txheej txheej thiab tsim kom muaj qhov sib txawv ntawm qhov zoo thiab qhov tsis zoo.

2. Pseudocapacitance:Nws tshwm sim ntawm qhov chaw electrode thiab nyob ze ntawm qhov chaw los yog nyob rau hauv cov theem ntawm ob sab los yog quasi-ob-dimensional qhov chaw, qhov twg cov ntaub ntawv electroactive undergo underpotential deposition, heev reversible tshuaj adsorption-desorption, thiab redox cov tshuaj tiv thaiv, uas ua rau muaj feem xyuam rau capacitance. mus rau electrode charging peev xwm. Rau pseudocapacitance, cov txheej txheem ntawm kev khaws cia tsis yog tsuas yog suav nrog kev khaws cia ntawm ob txheej tab sis kuj suav nrog cov tshuaj tiv thaiv redox ntawm electrolyte ions thiab cov khoom siv electrode.

Daim ntawv tseem ceeb ntawm lub zog cia yog supercapacitor lub zog cia. Ib qho khoom siv hluav taws xob supercapacitor feem ntau muaj xws li supercapacitor array, bidirectional DC / DC converter, thiab cov khoom sib txuas. Cov thev naus laus zis tseem ceeb nyob hauv qhov ntsuas hluav taws xob ntsuas hluav taws xob thiab tswj lub tswv yim nyob rau hauv lub supercapacitor array, nrog rau cov topology thiab tswj lub tswv yim ntawm bidirectional DC / DC converter.

Supercapacitor yog ib hom tshiab ntawm cov khoom siv hluav taws xob hluav taws xob uas nyob nruab nrab ntawm cov khoom siv hluav taws xob thiab cov roj teeb. Piv rau cov kev ua yeeb yam zoo, lawv muaj lub zog ua kom muaj zog dua, nrog cov khoom siv capacitations nce mus txog ntau txhiab tus kaum ntawm ntau txhiab tus farads; piv rau cov roj teeb, lawv muaj lub zog ntau dua thiab lub neej voj voog ntev heev, yog li sib txuas cov txiaj ntsig ntawm ob qho tib si capacitors thiab roj teeb, ua rau lawv muaj tshuaj lom neeg lub zog nrog rau kev thov dav dav.

Supercapacitors tsuas yog siv cov nqi thiab lub zog cia ua tiav los ntawm ob txheej txheej tsim ntawm electrode / electrolyte interface them nyiaj sib cais lossis los ntawm cov tshuaj tiv thaiv redox sai ntawm cov electrode nto thiab hauv cov electrode uas ua rau Faradaic "pseudocapacitance." Yog li ntawd, supercapacitors muaj cov yam ntxwv xws li kev them nyiaj ceev ceev, kev ua haujlwm zoo tam sim no, lub neej ntev ntev, thiab kev ua haujlwm kub ntau. Lub supercapacitor lub zog cia ntaus ntawv feem ntau muaj xws li supercapacitor array, ib tug bidirectional DC / DC converter, thiab coj mus muag circuits.
