I-capacitor ene-double-layer capacitor inokwandisa ubomi bebhetri yesithuthi sombane

Umbhali : Iflowpower - UMboneleli weSikhululo saMandla esiphathwayo

Ukuze kuphuhliswe isizukulwana esitsha sezithuthi zombane, iinkqubo zelanga kunye nezinye iteknoloji zamandla okucoca, abaphandi kufuneka babe nendlela efanelekileyo yokugcina amandla. Kukho isixhobo esibalulekileyo sokugcina amandla kwezi zicelo kunye nezinye izicelo, eziyi-supercapacitors, eyaziwa ngokuba yi-electro-layer capacitors (ElectricDouble-layercapacitor). I-nanophore ekhethekileyo ye-dimensional-dimensional array in the zeolite mine mold carbon, eyenza ukuba isetyenziswe njenge-electrode ukulungiselela i-supercapacitors ephezulu yokusebenza, i-capacitors enjalo inomthamo ophezulu kunye nexesha lokutshaja ngokukhawuleza.

Kuhlolisiso lwakutshanje, izazinzulu ziye zahlola umbandela onokusetyenziswa. Esi sixhobo sibizwa ngokuba yi-zeolite-TemplatedCarbon, enokusetyenziswa njenge-electrode yolu hlobo lwe-capacitor, bafumanisa ukuba oku I-aperture ekhethekileyo yezinto eziphathekayo kwandisa kakhulu ukusebenza ngokubanzi kwe-capacitor. I-Hiroyukiitoi, i-Western Hirotomonishihara, i-Taijikogure, i-Jinggang (i-Takashikyotani) esuka e-Sendai, kwiYunivesithi yaseNortheastern, kunye neziphumo ezipapashiweyo kukufunda umbane osebenza kakhulu.

I-Lamine capacitor, epapashwe kwi-US Chemistry Magazine yakutshanje (Journalsociety). Ukuze kugcinwe amandla, i-electric double layer capacitor ihlawulisa ukusebenzisa ii-ion, ezisuka kwi-bulksolution ukuya kwii-electrodes, apho zithengiswa khona. Ezi ion kufuneka zidlule kwi-nanopores encinci ngaphambi kokufikelela kumphezulu we-electrode, kwaye kuyimfuneko ukuba isebenze ngokufanelekileyo nangokufanelekileyo.

Ngokusisiseko, ngokukhawuleza i-ion idlula kwezi ndlela, ngokukhawuleza ukutshaja kwe-capacitor, kwaye kuya kuzisa ukusebenza kwesantya esiphezulu. Ukongezelela, ubukhulu be-adsorption ion density ye-electrode, inkulu intlawulo enokuthi igcinwe yi-capacitor, kunye ne-capacitance ephezulu. Kutshanje, izazinzulu bezivavanya izixhobo, zineendidi ezahlukeneyo zobukhulu kunye nolwakhiwo, kwaye zizame ukufezekisa ukuhanjiswa kwe-ion okukhawulezayo, kunye noxinzelelo oluphezulu lwe-adsorption ion.

Kodwa ezi mfuno zimbini ziyaphikisana kuba i-ion idlula kwi-nanopores enkulu, kodwa i-nanohole enkulu iya kuthoba ukuxinana kwe-electrode, ngaloo ndlela inciphisa ingxinano ye-adsorption ion. Kulo msebenzi, sicebise ngempumelelo ukuba kunokwenzeka ukuhlangabezana nezi mfuno zimbini ezibonakala ziphikisana, okukuhlangabezana noxinzelelo lwamandla aphezulu kunye nomthamo ophezulu, usebenzisa i-zeolite mine model board charcoal, kunye nesixeko sePhysicologists. Le zeolite mine mold carbon iqulethe i-1.

I-2 nanometers, ngaphantsi kwezinto ezininzi ze-electrode, kwaye inesakhiwo esicwangcisiweyo kakhulu, kunye neminye imingxuma inokuthi iphazamiseke kwaye ihlelwe. Ubungakanani obuncinci bale nanopore benza i-ion ye-adsorbed density, kwaye esi sakhiwo esicwangcisiweyo sichazwa njengesakhelo sedayimane, ukwenzela ukuba i-ion ikwazi ukudlula ngokukhawuleza kwi-nanopores. Kwizifundo zangaphambili, abaphandi bafumanisa ukuba i-nanohums ngaphezulu kwe-zeolite mine carbon yayingaphantsi kwe-1.

Ii-nanometers ze-2, ezingenakukwazi ukufezekisa ukuhanjiswa kwe-ion ngokukhawuleza, ebonisa ukuba esi silinganisi sinokubonelela ngebhalansi engcono kakhulu, eyona ibhalansi yokusebenza kwesantya esiphezulu kunye ne-capacitance capacitance. Kuvavanyo, ukusebenza kwe-zeolite mineral carbon idlula ezinye izinto, ebonisa ukuba ingasetyenziselwa njenge-electrode yokusebenza okuphezulu kombane ophindwe kabini. Ngoku sizama ukwandisa ubuninzi bamandla e-zeolite mine carbon carbon, ukuze ifikelele kwinqanaba elifanayo nebhetri yokutshaja, eNtshona.

Ukuba i-capacitor yombane ephindwe kabini yombane iphuhlisiwe, isetyenziselwa kuphela izixhobo eziphathwayo ezifana neefowuni eziphathwayo, kwaye ixesha lokutshaja linokufinyezwa kwimizuzu embalwa kuphela. Kukho elinye ithemba elibalulekileyo lesicelo, oko kukuthi, i-capacitor ephindwe kabini yombane inokuxhasa ibhetri yokutshaja yezithuthi zombane, ukwandisa ubomi bebhetri. Kananjalo ngenxa yale njongo, ukufezekisa ukuxinana kwamandla aphezulu ngumba ophambili.
