Vim lub ceev them ceev thiab siab conversion zog efficiency,super capacitorstuaj yeem siv tau ntau pua txhiab zaus thiab muaj sijhawm ua haujlwm ntev, tam sim no lawv tau siv rau cov tsheb npav tshiab.Lub zog tshiab tsheb uas siv supercapacitors raws li lub zog them tuaj yeem pib them thaum cov neeg caij tsheb nce thiab nqis tsheb npav.Ib feeb ntawm kev them nyiaj tuaj yeem tso cai rau lub zog tshiab tsheb mus rau 10-15 mais.Xws li supercapacitors zoo dua li cov roj teeb.Lub charger ceev ntawm cov roj teeb yog qeeb qeeb dua li ntawm super capacitors.Nws tsuas yog siv ib nrab teev kom them rau 70% -80% ntawm lub zog. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias ib puag ncig, kev ua haujlwm ntawm supercapacitors txo qis heev.Qhov no yog vim hais tias cov diffusion ntawm electrolyte ions yog hindered ntawm qhov kub thiab txias, thiab cov electrochemical kev ua tau zoo ntawm lub hwj chim cia li xws li supercapacitors yuav attenuated sai heev, uas ua rau ib tug heev txo ua hauj lwm efficiency ntawm supercapacitors nyob rau hauv qis kub ib puag ncig.Yog li puas muaj ib txoj hauv kev los ua kom lub supercapacitor tswj kev ua haujlwm zoo ib yam hauv qhov kub thiab txias? Yog lawm, photothermal-enhanced supercapacitors, supercapacitors tshawb fawb los ntawm pab pawg ntawm Wang Zhenyang tshawb fawb lub koom haum, lub koom haum ntawm Solid State tshawb fawb, Hefei tshawb fawb lub koom haum, Suav Academy ntawm Sciences.Nyob rau hauv qhov kub thiab txias ib puag ncig, electrochemical kev ua tau zoo ntawm supercapacitors yog heev attenuated, thiab siv cov khoom siv electrode nrog photothermal zog tuaj yeem ua tiav qhov kub siab ntawm cov cuab yeej los ntawm lub hnub ci photothermal nyhuv, uas yuav tsum tau txhim kho qhov kub tsis tshua muaj kev ua haujlwm ntawm supercapacitors. 
Cov kws tshawb fawb tau siv cov thev naus laus zis laser los npaj cov graphene siv lead ua zaj duab xis nrog cov qauv ntawm peb-dimensional ntxeem tau, thiab kev sib xyaw polypyrrole thiab graphene los ntawm cov tshuab hluav taws xob hluav taws xob los tsim cov graphene / polypyrrole cov electrode.Xws li cov electrode muaj lub peev xwm tshwj xeeb thiab siv lub hnub ci zog.Cov nyhuv photothermal paub qhov nce ceev ntawm electrode kub thiab lwm yam ntxwv.Rau lub hauv paus no, cov kws tshawb fawb tau tsim ib hom tshiab ntawm photothermally enhanced supercapacitor, uas tuaj yeem tsis tsuas yog nthuav tawm cov khoom siv hluav taws xob rau hnub ci, tab sis kuj tseem tiv thaiv cov khoom electrolyte.Nyob rau hauv ib cheeb tsam uas tsis muaj kub ntawm -30 ° C, electrochemical kev ua tau zoo ntawm supercapacitors nrog loj lwj tuaj yeem txhim kho sai rau hauv chav tsev kub nyob rau hauv tshav ntuj irradiation.Hauv chav tsev kub (15 ° C) ib puag ncig, qhov kub ntawm lub supercapacitor nce 45 ° C hauv qab hnub ci.Tom qab qhov kub thiab txias, lub electrode pore qauv thiab cov electrolyte diffusion tus nqi zoo heev, uas zoo heev txhim kho lub capacitor lub hwj chim cia muaj peev xwm.Tsis tas li ntawd, txij li cov khoom electrolyte muaj kev tiv thaiv zoo, lub peev xwm tuav tau ntawm lub capacitor tseem yog siab li 85.8% tom qab 10,000 tsub nqi thiab tawm. 
Cov txiaj ntsig kev tshawb fawb ntawm Wang Zhenyang pab pawg tshawb fawb ntawm Hefei Research Institute ntawm Suav Academy ntawm Sciences tau nyiam thiab tau txais kev txhawb nqa los ntawm cov haujlwm tseem ceeb hauv tsev R & D thiab Natural Science Foundation.Vam tias peb tuaj yeem pom thiab siv photothermally enhanced supercapacitors nyob rau yav tom ntej.
