I-Supercapacitor Ayesabi Izinga Lokushisa Eliphansi

Ngenxa yesivinini sokushaja esisheshayo kanye nokusebenza kahle kwamandla okuguqulwa,ama-super capacitorszingagaywa kabusha izikhathi ezingamakhulu ezinkulungwane futhi zibe namahora amade okusebenza, manje sezifakwe emabhasini anamandla amasha.Izimoto zamandla amasha ezisebenzisa ama-supercapacitor njengamandla okushaja zingaqala ukushaja lapho abagibeli bengena futhi behla ebhasini.Umzuzu owodwa wokushaja ungavumela izimoto ezisebenza ngamandla ukuthi zihambe amakhilomitha ayi-10-15.Ama-supercapacitor anjalo angcono kakhulu kunamabhethri.Isivinini sokushaja samabhethri sihamba kancane kunesama-super capacitor.Kuthatha isigamu sehora kuphela ukushaja ku-70% -80% wamandla. Kodwa-ke, ezindaweni zokushisa eziphansi, ukusebenza kwama-supercapacitor kuyancipha kakhulu.Lokhu kungenxa yokuthi ukusakazeka kwama-ion e-electrolyte kuyavinjelwa emazingeni okushisa aphansi, futhi ukusebenza kwe-electrochemical yamathuluzi okugcina amandla njengama-supercapacitor kuzoncishiswa ngokushesha, okuzophumela ekwehleni kakhulu ukusebenza kahle kwama-supercapacitor ezindaweni ezishisayo.Ngakho-ke ingabe ikhona indlela yokwenza i-supercapacitor igcine ukusebenza kahle okufanayo endaweni yokushisa ephansi? Yebo, ama-supercapacitor athuthukisiwe e-photothermal, ama-supercapacitor acwaningwa yiqembu le-Wang Zhenyang Research Institute, i-Institute of Solid State Research, i-Hefei Research Institute, i-Chinese Academy of Sciences.Endaweni yokushisa ephansi, ukusebenza kwe-electrochemical kwama-supercapacitor kuncishiswa kakhulu, futhi ukusetshenziswa kwezinto ze-electrode ezinezakhiwo ze-photothermal kungafinyelela izinga lokushisa elisheshayo ledivayisi ngomphumela we-solar photothermal, okulindeleke ukuthi kuthuthukiswe ukusebenza okuphansi kwezinga lokushisa kwama-supercapacitors. i-supercapacitor ayesabi izinga lokushisa eliphansi Abacwaningi basebenzise ubuchwepheshe be-laser ukuze balungiselele ifilimu yekristalu ye-graphene enesakhiwo esinezimbotshana ezinezinhlangothi ezintathu, kanye ne-polypyrrole edidiyelwe kanye ne-graphene ngobuchwepheshe be-electrodeposition obugayiwe ukuze bakhe i-graphene/polypyrrole composite electrode.I-electrode enjalo inomthamo othize ophezulu futhi isebenzisa amandla elanga.Umphumela we-photothermal uqaphela ukunyuka okusheshayo kwezinga lokushisa le-electrode nezinye izici.Ngalesi sisekelo, abacwaningi baqhubeka nokwakha uhlobo olusha lwe-supercapacitor ethuthukisiwe nge-photothermally, engakwazi ukuveza izinto ze-electrode ekukhanyeni kwelanga, kodwa futhi ivikele ngempumelelo i-electrolyte eqinile.Endaweni yokushisa ephansi engu -30 °C, ukusebenza kwe-electrochemical kwama-supercapacitor anokonakala okukhulu kungathuthukiswa ngokushesha kube izinga lokushisa legumbi ngaphansi kwemisebe yelanga.Ezingeni lokushisa legumbi (15°C), izinga lokushisa elingaphezulu le-supercapacitor lenyuka ngo-45°C ngaphansi kokukhanya kwelanga.Ngemva kokukhuphuka kwezinga lokushisa, ukwakheka kwembobo ye-electrode kanye nezinga lokusabalalisa i-electrolyte likhuphuka kakhulu, okuthuthukisa kakhulu umthamo wokugcina ugesi we-capacitor.Ukwengeza, njengoba i-electrolyte eqinile ivikelwe kahle, izinga lokugcinwa kwe-capacitance le-capacitor lisephezulu njenge-85.8% ngemva kwezindleko ezingu-10,000 nokukhishwa. I-supercapacitor ayesabi izinga lokushisa eliphansi 2 Imiphumela yocwaningo yethimba labacwaningi lika-Wang Zhenyang e-Hefei Research Institute of the Chinese Academy of Sciences idonse ukunaka futhi iye yasekelwa amaphrojekthi asekhaya abalulekile e-R&D kanye ne-Natural Science Foundation.Ngethemba ukuthi singabona futhi sisebenzise ama-supercapacitor athuthukisiwe nge-photothermally maduze nje.
