Tsis ntev los no, Longwei Yin pab neeg tshawb fawb los ntawm Shandong University tau luam tawm ib tsab xov xwm ntawm Energy & Environmental Science, lub npe yog Alkali-induced 3D crinkled ntxeem tau Ti3C2 MXene architectures ua ke nrog NiCoP bimetallic phosphide nanoparticles ua anodes rau high-kev ua tau zoo sodium-ion roj teeb.
Txhawm rau txhim kho cov qauv kev ruaj ntseg thiab txhim kho qhov tsis zoo electrochemical tshuaj tiv thaiv kinetics ntawm anodes rau sodium ion roj teeb (SIBs), lawv tsim cov tswv yim tshiab rau ob peb NiCoP bimetallic phosphide nanoparticles nrog alkali-induced 3D interconnected crinkled ntxeem tau Ti3C2 MXenes ua anodes rau high-performance. .
Cov kev sib txuas 3D Ti3C2 crinkled architectures tuaj yeem tsim kom muaj 3D conductive network, ntau qhib qhov hws thiab thaj chaw loj, uas muab 3D conductive txoj kev loj thiab unblocked raws rau tus txheej txheem hloov ceev ceev thiab rau electrolyte cia, thiab ua kom muaj kev sib raug zoo ntawm electrode thiab electrolyte.Cov qauv MXene tshwj xeeb tuaj yeem zam qhov ntim nthuav dav thiab tiv thaiv kev sib sau ua ke thiab pulverization ntawm NiCoP nanoparticles thaum lub sijhawm Na + ntxig / rho tawm cov txheej txheem.NiCoP bimetallic phosphide muaj cov tshuaj tiv thaiv redox ntau dua, muaj hluav taws xob ntau dua thiab tsis muaj nqi hloov pauv impedance.Lub synergistic nyhuv ntawm lub Cheebtsam ntawm NiCoP thiab MXene Ti3C2 nrog siab structural stability thiab electrochemical kev ua si ua rau zoo heev electrochemical kev ua tau zoo, tuav ib tug tshwj xeeb muaj peev xwm ntawm 261.7 mA hg-1ntawm qhov ceev tam sim no ntawm 1 A g-1rau 2000 cycles.Tam sim no lub tswv yim ntawm ibhauv qhovphosphization txoj kev thiab coupling phosphides nrog crinkled 3D Ti3C2 yuav txuas mus rau lwm yam tshiab electrodes rau high-kev ua tau zoo zog cia khoom.
