I-Supercapacitor Ayiloyiki uBubushushu obuphantsi

Ngenxa yesantya sokutshaja ngokukhawuleza kunye nokusebenza kakuhle kwamandla okuguqula,ii-capacitors ezinkuluzinokuphinda zisetyenziswe ngamakhulu amawaka amaxesha kwaye zineeyure zokusebenza ezinde, ngoku zisetyenziswe kwiibhasi zamandla amatsha.Izithuthi zamandla amatsha ezisebenzisa ii-supercapacitors njengamandla okutshaja zinokuqala ukutshaja xa abakhweli bekhwela kwaye bephuma ebhasini.Umzuzu omnye wokutshaja unokuvumela iimoto zamandla amatsha ukuba zihambe i-10-15 yeekhilomitha.Ii-supercapacitors ezinjalo zingcono kakhulu kuneebhetri.Isantya sokutshaja iibhetri sicotha kakhulu kuneso se-super capacitors.Kuthatha isiqingatha seyure kuphela ukuhlawula ukuya kwi-70% -80% yamandla. Nangona kunjalo, kwiindawo eziphantsi kweqondo lokushisa, ukusebenza kwe-supercapacitors kuyancipha kakhulu.Oku kungenxa yokuba ukusasazwa kwee-ion ze-electrolyte kuthintelwa kumaqondo obushushu aphantsi, kwaye ukusebenza kwe-electrochemical yezixhobo zokugcina amandla ezinjenge-supercapacitors ziya kuthotywa ngokukhawuleza, okukhokelela ekunciphiseni kakhulu ukusebenza kakuhle kwee-supercapacitors kwindawo zobushushu obuphantsi.Ngaba kukho nayiphi na indlela yokwenza i-supercapacitor igcine ukusebenza kakuhle okufanayo kwindawo yokushisa ephantsi? Ewe, i-photothermal-enhanced supercapacitors, ii-supercapacitors eziphandwe liqela le-Wang Zhenyang Research Institute, i-Institute of Solid State Research, i-Hefei Research Institute, i-Chinese Academy of Sciences.Kwimeko yobushushu obuphantsi, ukusebenza kwe-electrochemical ye-supercapacitors kuncitshiswe kakhulu, kwaye ukusetyenziswa kwezixhobo ze-electrode ezineempawu ze-photothermal kunokufikelela ngokukhawuleza kweqondo lokushisa kwesixhobo ngokusebenzisa i-solar photothermal effect, ekulindeleke ukuba iphucule ukusebenza kobushushu obuphantsi be-supercapacitors. i-supercapacitor ayiloyiki ubushushu obuphantsi Abaphandi basebenzise itekhnoloji ye-laser ukulungisa ifilimu yekristale yegraphene ene-porous-dimensional structure, kunye nepolypyrrole edibeneyo kunye negraphene ngeteknoloji ye-pulsed electrodeposition ukwenza igraphene/polypyrrole composite electrode.I-electrode enjalo inamandla athile aphezulu kwaye isebenzisa amandla elanga.Impembelelo ye-photothermal iqonda ukunyuka ngokukhawuleza kweqondo lokushisa kwe-electrode kunye nezinye iimpawu.Ngesi siseko, abaphandi baqhubela phambili ukwakha uhlobo olutsha lwe-photothermally ephuculweyo ye-supercapacitor, engakwaziyo ukuveza izinto ze-electrode ekukhanyeni kwelanga, kodwa kunye nokukhusela ngokufanelekileyo i-electrolyte eqinile.Kwindawo yokushisa ephantsi kwe--30 ° C, ukusebenza kwe-electrochemical ye-supercapacitors ngokubola okukhulu kunokuphuculwa ngokukhawuleza kwinqanaba leqondo lokushisa phantsi kokukhanya kwelanga.Kwiqondo lokushisa legumbi (15 ° C), iqondo lokushisa elingaphezulu kwe-supercapacitor landa ngo-45 ° C phantsi kokukhanya kwelanga.Emva kokunyuka kweqondo lokushisa, i-electrode pore structure kunye ne-electrolyte diffusion rate inyuka kakhulu, nto leyo iphucula kakhulu amandla okugcina umbane we-capacitor.Ukongezelela, ekubeni i-electrolyte eqinile ikhuselwe kakuhle, izinga lokugcinwa kwe-capacitance ye-capacitor lisephezulu njenge-85.8% emva kweentlawulo ze-10,000 kunye nokukhutshwa. I-supercapacitor ayiloyiki ubushushu obuphantsi 2 Iziphumo zophando zeqela lophando likaWang Zhenyang kwiZiko loPhando leHefei leChinese Academy of Sciences litsale umdla kwaye lixhaswe ziiprojekthi ezibalulekileyo zasekhaya zeR&D kunye neSiseko seSayensi yeNdalo.Ngethemba siyakwazi ukubona kwaye sisebenzise ii-supercapacitors eziphuculweyo ezifotothermally kungekudala.
