Abstract：

Advanced　electrode　design　is　critical　for　the　rapid　development　of　flexible　energy　storage　devices　(ESD)　in　the　emerging　field　of　flexible　electronics.　Metal-organic　frameworks　((MOFs)　for　lithium　storage　have　attracted　considerable　attention.　However,　one　of　the　main　obstacles　is　their　poor　electronic　conductivity,　which　restricts　their　cycling　stability　under　redox　conditions.　Herein,　we　report　a　facile　synthesis　route　to　fabricate　Ni(BDC-NH2)/reduced　graphene　oxide　(rGO)　composites　employing　the　solvothermal　method.　Ni(BDC-NH2)　MOFs　exhibited　a　unique　laminar　and　porous　morphology,　which　helps　with　Li-ion　diffusion,　and　thus　enables　faster　electrode　activation　and　capacitive　controlled　electrochemical　activity.　When　freestanding　Ni(BDC-NH2)/reduced　graphene　oxide　(rGO)　composite　electrode　was　prepared　via　simple　vacuum　filtration.　As　anode　material　for　lithium-ion　batteries.　It　delivered　a　reversible　capacity　of　813　mAh　g−1　at　a　current　density　of　200　mA　g−1　after　100　cycles.　More　importantly,　it　also　shows　an　excellent　rate　of　performance　compared　to　Ni(BDC)/rGO　MOFs.　The　better　electrochemical　performance　of　Ni(BDC-NH2)/rGO　is　attributed　to　the　unique　chain　network　formed　by　the　synergistic　eect　of　multi-coordination　of　carboxylic　oxygen　and　amino　nitrogen　with　high　theoretical　capacities　and　rGO　with　high　electrical　conductivity.　©　2022
