Muva nje, ithimba labacwaningi likaLongwei Yin laseNyuvesi yaseShandong lishicilele isihloko esithi I-Energy & Environmental Science, isihloko nge-Alkali-induced 3D crinkled porous Ti3C2 MXene architectures ehlanganiswe ne-NiCoP bimetallic phosphide nanoparticles njengama-anode amabhethri e-sodium-ion asebenza kakhulu.
Ukuze kuthuthukiswe ukuqina kwesakhiwo futhi kuthuthukiswe ukungasebenzi kahle kwe-electrochemical kinetics ye-anode yamabhethri e-sodium ion (SIBs), bakha isu elisha lokubhangqa ama-NiCoP bimetallic phosphide nanoparticles ane-alkali-induced 3D exhumene exhumene ne-Ti3C2 MXenes eqinile njenge-anode yama-SIB asebenza kahle kakhulu. .
Izakhiwo ezixhumene ze-3D Ti3C2 ezigoqekile zingasungula inethiwekhi ye-3D conductive, izimbotshana eziningi ezivulekile nendawo enkulu, ehlinzeka ngothelawayeka onguthelawayeka we-3D namashaneli avuliwe enqubo yokudlulisa ukushaja okusheshayo kanye nokugcinwa kwe-electrolyte, futhi yenza ukuxhumana okuseduze ngokugcwele phakathi kwe-electrode kanye i-electrolyte.Isakhiwo esiyingqayizivele se-MXene singabekezelela ngokuphumelelayo ukunwetshwa kwevolumu futhi kuvimbele ukuhlanganisa kanye nokukhishwa kwe-NiCoP nanoparticles phakathi nezinqubo zokufaka / zokukhipha i-Na+.I-NiCoP bimetallic phosphide inezindawo zokusabela ezicebile ze-redox, ukuqhutshwa kogesi okuphakeme kanye ne-impedance yokudlulisa imali ephansi.Umthelela we-synergistic phakathi kwezingxenye ze-NiCoP ne-MXene Ti3C2 ezinokuzinza okuphezulu kwesakhiwo nomsebenzi we-electrochemical uholela ekusebenzeni okuhle kakhulu kwe-electrochemical, egcina umthamo othize ongu-261.7 mA hg.-1ekumineni kwamanje kwe-1 A g-1imijikelezo engu-2000.Isu lamanje le-endaweniUmzila we-phosphization kanye nama-phosphide ahlanganisayo ane-3D Ti3C2 eshwabene anganwetshwa kwamanye ama-electrode anoveli kumadivayisi okugcina amandla asebenza kahle kakhulu.
