Ibhetri yeGraphite feltIdlala indima ebalulekileyo kubuchwepheshe bebhetri yanamhlanje, ingakumbi kwiibhetri ezihambayo kunye neeseli zepetroli. Njengento esebenzayo nehlala ixesha elide, i-graphite felt inika ukuhanjiswa kombane okugqwesileyo kunye nokuzinza kobushushu, ngelixa ikwanegalelo ekuphuculweni kokusebenza kwebhetri, ixesha elide lokuphila, kunye nokhuseleko oluphuculweyo. Ekusetyenzisweni kweebhetri ezihambayo kunye neeseli zepetroli, iimpawu ezikhethekileyo ze-graphite felt yebhetri zenza ukuba ibe yinxalenye ebalulekileyo kwezi nkqubo zokugcina amandla ezisebenzayo.
Ukusetyenziswa kweGraphite Battery Felt kwiibhetri zeFlow
Iibhetri zeflow, ngakumbi iibhetri zevanadium redox flow (VRFB) kunye neebhetri zeflow ze-zinc-bromine, ziphandwa kakhulu kwaye zisetyenziswa kubuchwepheshe bokugcina amandla. Zigcina kwaye zikhuphe amandla ngezinto ezisebenzayo ezinyibilikiswe kwi-electrolyte, nto leyo ezinika ubomi obude kunye namandla amakhulu okugcina amandla xa kuthelekiswa neebhetri zemveli. Kuyilo lwezi bhetri, i-graphite battery felt isetyenziswa rhoqo kwiindawo ze-electrode, ingakumbi apho i-electrolyte ehambayo idibana nezinto ze-electrode.
Ukuqhuba okuphezulu kwe-graphite felt yeyona nzuzo iphambili ekusebenziseni kwayo kwiibhetri zokuhamba. Kwiibhetri zokuhamba, i-electrochemical reaction yenzeka phakathi kwe-electrolyte kunye nee-electrodes, ngoko ke ukuqhuba kwe-electrodes kubaluleke kakhulu ekusebenzeni kwebhetri. Njengesixhobo se-electrode, i-graphite felt inokukhuthaza ngokufanelekileyo intshukumo yee-ions kwi-electrolyte kwaye iqinisekise ukudluliselwa kwe-electron ngokufanelekileyo, nto leyo ephucula ukusebenza kakuhle kwebhetri ngokutshaja kunye nokukhupha.
Ukongeza, i-graphite felt idlala indima ebalulekileyo ekulawuleni ubushushu ngaphakathi kweebhetri zokuhamba. Ngexesha lokusebenza kweebhetri zokuhamba, ubushushu bangaphakathi buyaveliswa. Ukuqhuba kakuhle kobushushu be-graphite felt kunceda ukuphelisa obu bushushu, kuthintele ibhetri ekutshiseni kakhulu kwaye kuqinisekise ukuba isebenza ngaphakathi komgangatho wobushushu ofanelekileyo. Olu buchule bokulawula ubushushu abuncedi nje kuphela ekwandiseni ubomi bebhetri kodwa bukwaphucula ukhuseleko lwayo, bunciphisa umngcipheko wokungasebenzi kwebhetri ngenxa yobushushu obugqithisileyo.
Ukusetyenziswa kweGraphite Battery Felt kwiiseli zeFuel
Iiseli zepetroli zizixhobo eziguqula ngokuthe ngqo amandla eekhemikhali abe ngamandla ombane ngokusebenzisa ii-electrochemical reactions, ezisetyenziswa kakhulu kwizithuthi zombane, izixhobo zamandla ezixhasayo, kunye neenkqubo zamandla avuselelekayo. Ukusetyenziswa kwebhetri yegrafiti evezwa kwiiseli zepetroli ngokuyintloko kuxhomekeke kwindima yayo njengomaleko wokusasazwa kwegesi (i-GDL) kunye nezinto ze-electrode. Ukubaluleka kwayo kubonakala ngakumbi kwiiseli zepetroli ze-proton exchange membrane (i-PEMFC).
Kwiiseli zepetroli, i-graphite felt isebenza njengomaleko wokusasazwa kwegesi (GDL), enoxanduva lokusasaza ngokulinganayo iigesi ezisabelayo ezifana ne-hydrogen kunye ne-oxygen kwiindawo ze-electrode, ngelixa isebenza njengendawo yokuhambisa umbane. Ngenxa yokuqhuba kwayo kakuhle, i-graphite felt inokudlulisa ngokufanelekileyo ii-electron ezenziwe ngaphakathi kwiseli ukuya kwisekethe yangaphandle, ivumela ukuphuma kwamandla ombane. Ulwakhiwo lwayo olunemingxuma lukwanceda ukusasazeka kwegesi kunye nokuhanjiswa kwe-electrolyte, ukuqinisekisa ukuba iimpendulo ze-electrochemical kwiiseli zepetroli ziqhubeka ngokufanelekileyo.
I-graphite evalwayo kwiiseli zepetroli ayifuni nje kuphela ukubonelela ngombane oqhuba kakuhle, kodwa kufuneka ikwabe nokumelana nokugqwala okugqwesileyo kunye nokusebenza kakuhle kobushushu obuphezulu. Ekubeni iiseli zepetroli zisebenza kwiindawo ezinobushushu obuphezulu kunye nezonakalayo, ukuzinza kweekhemikhali kunye nokuzinza kobushushu be-graphite felt kwenza kube lukhetho olufanelekileyo. Ingasebenza ngokuzinzileyo kwiimeko ezinzima kangangexesha elide, iphephe ukuwohloka kokusebenza ngenxa yokuguga kwezinto okanye ukugqwala.
Ngaphezu koko, i-graphite evalwayo kwiiseli zamafutha ikwanceda ukuphucula ukusebenza kakuhle kwempendulo ngokusebenzisa ulwakhiwo lwayo oluyilwe kakuhle. Ukulungelelaniswa kunye nokubekwa kweefayibha ze-graphite akupheleli nje ekuphuculeni amandla ayo oomatshini kodwa kukwaphucula nokusebenza kakuhle kokuhamba kwegesi. Ngokulungisa ngokuchanekileyo i-porosity kunye nohlobo lwesakhiwo se-graphite felt, amandla okukhupha kunye nokusebenza kweeseli zamafutha kunokuphuculwa ngakumbi.
Uphuhliso lwexesha elizayo lweGraphite Battery Felt
Njengoko ubuchwepheshe bebhetri yokuhamba kunye neeseli zepetroli buqhubeka nokukhula, amathuba okusetyenziswa kwefeliti yebhetri yegraphite ayanda. Abaphandi baphonononga iindlela zokuphucula ngakumbi ukusebenza kwefeliti yebhetri yegraphite ngokusebenzisa ii-graphite composites, iindlela zokusebenzisa idoping, kunye nonyango lomphezulu. Umzekelo, ukuphucula uyilo lwesakhiwo sefeliti yebhetri yegraphite kunokunyusa ukuhanjiswa kwayo, kuphucule ukumelana kwayo nokugqwala, kwaye kuphucule amandla olawulo lobushushu. Olu phuculo luya kuphucula ngakumbi ukusetyenziswa kweebhetri zokuhamba kunye neeseli zepetroli kwiindawo zokugcina amandla kunye nokuguqula amandla ezisebenza kakhulu.
Ukuqukumbela, ukusetyenziswa kwebhetri yegrafiti evalwayo kwiibhetri zokuhamba kunye neeseli zepetroli, kunye nokuqhuba kwayo okugqwesileyo, amandla okulawula ubushushu, kunye nokuzinza kwesakhiwo, kuye kwaba yinto ephambili kwezi nkqubo zokugcina amandla eziphambili kunye nokuguqula. Njengoko ubuchwepheshe bamandla buqhubeka buphuhla, ibhetri yegrafiti evalwayo iya kudlala indima ebaluleke ngakumbi ekuqhubeni ubuchule beteknoloji yebhetri, ukuphucula ukusebenza kakuhle kwamandla, kunye nokuqhubela phambili uphuhliso oluzinzileyo.
