LiNi0.8Co0.15Al0.05O2　(NCA)　has　become　one　of　the　research　focuses　due　to　its　advantages　including　low　cost　and　high　reversible　capacity.　However,　many　drawbacks　such　as　the　dissolution　of　the　cation　into　the　electrolyte　caused　by　hydrofluoric　acid　severely　limited　its　electrochemical　performance.　In　this　study,　Co3O4　derived　from　metal-organic　frameworks　(MOFs)　is　coated　on　the　surface　of　commercial　NCA　utilizing　in　situ　growth　followed　by　annealing.　The　structure　and　morphology　of　the　samples　are　characterized　by　X-ray　diffraction,　scanning　electron　microscope,　and　transmission　electron　microscope.　NCA@Co3O4　delivers　a　remarkable　capacity　retention　of　73.7%　and　84.4%　at　1C　and　2C　after　100cycles　at　each　rate,　respectively.　Meanwhile,　the　rate　performance　of　NCA@Co3O4　is　significantly　improved.　The　inhibition　of　the　side　reaction　between　cathode　materials　and　electrolyte,　and　the　reduced　charge-transfer　resistance　that　brought　by　Co3O4　coating　layer　are　the　main　reasons　for　the　excellent　electrochemical　performance.
