Isitini esivamile njenge-supercapacitor? Ngiyacela, nansi i-polymer eyenza isitolo sikagesi.
Ososayensi abavela eNyuvesi yaseWashington eSt. Louis udale igobolondo le-polymer elingakwazi ukuguqula isitini sibe idivayisi encane yokugcina amandla (i-supercapacitor). Konke sibonga i-iron oxide, udayi onikeza isitini umbala waso obomvu.
Isitini esondla i-diode? Ingabe i. Esikhathini esizayo? Ukunikezwa kwamandla kalambu, isitoreji samandla sasekhaya, ...
Abacwaningi abavela enyuvesi okukhulunywe ngayo ngenhla bazibekele umgomo wokusebenzisa izimpahla eziseduze kwethu, ezishibhile nezidumile. Phakathi kokunye, wawela phezu kokugqwala nezitini. Izitini zobumba ezivamile, eziphenduka zibebomvu ngenxa yokuba khona kwe-iron oxide. Ziye zaqashelwa ukuthi zinesakhiwo esinezimbotshana ezingasetshenziswa ekugcineni amandla.
Izakhiwo ezinama-porous nazo zisetshenziswa, isibonelo, kuma-electrode. Ngevolumu engaguquki, indawo enkulu ye-electrode, iyanda amandla eseli ekugcineni. Kodwa emuva ezitini.
> Iviki elisha nebhethri elisha: I-LeydenJar ine-silicon anode namabhethri angama-170%. isikhathi samanje
Ososayensi benze i-polymer (PEDOT) eyenziwe ngama-nanofibers elungele ukumboza izitini nokwandisa indawo yazo. Ama-nanofiber e-polymer asabela nge-iron oxides equkethwe ezintweni zokwakha izitini futhi ikuvumela ukuthi ugcine umthwalo othile kuwo. Lokhu kushaja kuzokwanela isikhathi esithile ukunika amandla i-diode:
Ukuvimbela amanzi, isitini singahlanganiswa ne-epoxy. Ngenxa yokusetshenziswa kwe-electrolyte yejeli ehlanganisa zonke izingqimba, isitini esinjalo singabamba amaphesenti angama-90 omthamo waso Izinkulungwane eziyi-10 (!) Imijikelezo yokusebenza. Idivayisi - ngoba isivele iyisisetshenziswa - ingasebenza ebangeni -20 kuya ku-60 degrees Celsius, okujwayelekile kumaseli e-lithium-ion. amandla 3,6 volts ingatholwa nge-serial uxhumano lwezixhumanisi ezintathu (izitini).
Yiqiniso, nakuba isitini siyinto eshibhile, into ye-polymer ene-nanofibers ayilona iqiniso ngokuphelele. Nokho, ucwaningo lubonisa amandla amakhulu: cabanga ukuthi olunye lwezindonga zendlu yethu luba indawo yokugcina amandla. Lokhu kungaba, isibonelo, ukwahlukanisa, okungahlala kubhidlizwa futhi kushintshwe lapho izitini zesixhumanisi sezigugile.
Waba yini umphumela? Iyunithi yesitoreji samandla exhunywe ophahleni lwendlu yokufakwa kwe-photovoltaic nokuzimela okuphelele kugridi yamandla yesisebenzisi... Lesi sinqumo sibaluleke kakhulu uma uzwa izindaba eziningi zokuthi abahlinzeki bamandla bavala ukufakwa bekude ngoba ngeke besakwazi ukumelana namandla angaphezu kwamandla akhiqizwayo.
Kuyafaneleka ukufunda: Amabhlogo okonga amandla wama-supercapacitor amile PEDOT
Lokhu kungase kube nentshisekelo kuwe:
