Kev kawm tsis ntev los no ntawm sodium ion roj teeb kev tshawb fawb ntawm Qingdao University, Suav
Cov kws tshawb fawb ntawm Qingdao University hauv Suav teb tau tsim cov kev ua haujlwm siab titanium dioxide raws li cov ntaub ntawv anode nrog kev ruaj ntseg zoo.
Anatase titanium dioxide (TiO2) yog cov khoom cog lus anode rau sodium-ion roj teeb vim nws cov nqi qis, tsis muaj tshuaj lom thiab muaj ntau, raws li cov kws tshawb fawb ntawm Qingdao University.
Ib pab neeg tshawb fawb los ntawm Lub Tsev Kawm Ntawv ntawm Cov Khoom Siv Science thiab Engineering ntawm Qingdao University hauv Suav teb tau qhia txog kev sib txuas ntawm nanoparticles nrog lub plhaub carbon raws li cov khoom tseem ceeb rau kev siv cov khoom siv sodium ion roj teeb anode.
Thaum cov synthetic anatase tau sim nyob rau hauv ib nrab-cell, hom cell qhia ib tug reversible lub peev xwm ntawm 228 mA ntawm ib tug tam sim no ceev ntawm 0.05 A g-1, uas tseem 100 feem pua tom qab 2000 cycles ntawm 1a g-1, raws li Qingdao University cov kws tshawb fawb.
Nyob rau hauv situ X-ray diffraction thiab Raman spectroscopy tshwm sim qhia tau hais tias anatase muaj zero strain thaum lub sij hawm them thiab tawm. Cov txiaj ntsig ntawm situ kis tau tus mob electron microscopy, nyob rau hauv situ X-ray photoelectron spectroscopy thiab scanning electron microscopy qhia tau hais tias lub Natidized tio2 theem tau tsim los ntawm ib tug irreversible natriuretic activation txheej txheem thaum pib tawm.
Cov kev tshawb fawb tau qhia tias KEV SIV NTAWM IONS, thaum nrog los ntawm kev daws teeb meem hauv lub lattice, hu ua "co-interCALation". Txog tam sim no, lub tswv yim tau txwv rau qhov tsis zoo kawg ntawm sodium-ion roj teeb.
Cov kws tshawb fawb pom tau hais tias los ntawm kev ua qhov ntsuas operando ntawm HZB X-ray Core Laboratory ntawm LIMAX 160, cov kws tshawb fawb tuaj yeem soj ntsuam cov kev hloov pauv ntawm cov khoom thaum nws them thiab tawm. Qhov no pab lawv faib cov co-insertion mechanism hauv lub roj teeb. Thiab lawv tuaj yeem tsim cov roj teeb zoo dua.
Cov kws tshaj lij hais tias cov txheej txheem sib koom ua ke tuaj yeem txhim kho cov roj teeb ua haujlwm tau zoo los ntawm kev ua tiav qhov kev ua haujlwm kub qis dua. Nws tuaj yeem siv los txhim kho lossis hloov lub tswvyim roj teeb.
