Supercapacitor Osawopa Kutentha Kwambiri

Chifukwa cha kuthamanga kwachangu komanso kusinthika kwakukulu kwamphamvu,super capacitorsamatha kubwezeretsedwanso kambirimbiri ndipo amakhala ndi nthawi yayitali yogwira ntchito, tsopano agwiritsidwa ntchito pamabasi amagetsi atsopano.Magalimoto amphamvu atsopano omwe amagwiritsa ntchito ma supercapacitor monga mphamvu zolipirira amatha kuyamba kuyitanitsa okwera akakwera ndi kutsika basi.Kulipiritsa kwa mphindi imodzi kumatha kuloleza magalimoto amphamvu atsopano kuyenda mtunda wa makilomita 10-15.Ma supercapacitor oterowo ndi abwino kwambiri kuposa mabatire.Kuthamanga kwa mabatire ndikocheperako kuposa ma super capacitor.Zimangotenga theka la ola kuti mupereke 70% -80% ya mphamvu. Komabe, m'malo otsika kutentha, ntchito ya supercapacitors imachepetsedwa kwambiri.Izi zili choncho chifukwa kufalikira kwa ma ion a electrolyte kumalepheretsa kutentha pang'ono, ndipo magwiridwe antchito a electrochemical a zida zosungira magetsi monga ma supercapacitor adzachepetsedwa mwachangu, zomwe zimapangitsa kuti ma supercapacitor achepetse kwambiri m'malo otentha kwambiri.Ndiye kodi pali njira iliyonse yopangira kuti supercapacitor ikhalebe yogwira ntchito bwino m'malo otentha otsika? Inde, ma photothermal-enhanced supercapacitors, supercapacitors ofufuza ndi gulu la Wang Zhenyang Research Institute, Institute of Solid State Research, Hefei Research Institute, Chinese Academy of Sciences.M'malo otentha kwambiri, mphamvu ya electrochemical ya supercapacitor imachepetsedwa kwambiri, ndipo kugwiritsa ntchito zinthu za electrode zomwe zili ndi photothermal zimatha kupititsa patsogolo kutentha kwa chipangizochi kudzera mu mphamvu ya dzuwa ya photothermal, yomwe ikuyembekezeka kupititsa patsogolo kutentha kwapamwamba kwa supercapacitors. Ofufuzawa adagwiritsa ntchito ukadaulo wa laser pokonzekera filimu ya graphene crystal yokhala ndi mawonekedwe amitundu itatu, ndi polypyrrole yophatikizika ndi graphene kudzera muukadaulo wa pulsed electrodeposition kuti apange graphene/polypyrrole composite electrode.Electrode yotereyi imakhala ndi mphamvu zapadera ndipo imagwiritsa ntchito mphamvu za dzuwa.Mphamvu ya photothermal imazindikira kukwera mofulumira kwa kutentha kwa electrode ndi makhalidwe ena.Pazifukwa izi, ofufuzawo adapanganso mtundu watsopano wa supercapacitor wopangidwa ndi photothermally, womwe sungathe kungowonetsa zinthu za elekitirodi ku dzuwa, komanso kuteteza bwino electrolyte yolimba.M'malo otentha otsika -30 ° C, magwiridwe antchito a electrochemical a supercapacitor omwe amawola kwambiri amatha kusintha mwachangu mpaka kutentha kwachipinda pansi pakuwala kwa dzuwa.M'malo otentha (15 ° C), kutentha kwapamwamba kwa supercapacitor kumawonjezeka ndi 45 ° C pansi pa dzuwa.Kutentha kukakwera, mawonekedwe a pore a electrode ndi kuchuluka kwa ma electrolyte amachulukirachulukira, zomwe zimathandizira kwambiri kusungirako magetsi kwa capacitor.Kuonjezera apo, popeza electrolyte yolimba imatetezedwa bwino, mphamvu yosungira mphamvu ya capacitor idakalipo mpaka 85,8% pambuyo pa milandu 10,000 ndi kutulutsa. Zotsatira za kafukufuku wa gulu la kafukufuku wa Wang Zhenyang ku Hefei Research Institute of the Chinese Academy of Sciences zakopa chidwi ndipo zathandizidwa ndi ntchito zofunika zapakhomo za R&D ndi Natural Science Foundation.Tikukhulupirira titha kuwona ndikugwiritsa ntchito ma supercapacitor opangidwa ndi Photothermally posachedwa.
