Advancing Li-ion storage performance with hybrid vertical carbon/Ni3S2-based electrodes
文献摘要：
Conversion-reaction induced charge storage mechanisms of transition metal sulphides have received considerable interest in designing high-capacity electrodes for electrochemical energy storage devices.However,their low conductivity and structural degradation during cycling limit their applications as energy storage devices.A combination of different nickel sulphide phases tailored with carbon nanostruc-tures is suggested to address these limitations.Herein,a facile,two-step approach is demonstrated for fabricating a hybrid electrode,consisting of trinickel disulphide(Ni3S2)formed on a metallic Ni nanopar-ticle supported by vertical carbon nanotubes(VCN)backbone in the form Ni3S2/Ni@VCN.Ni3S2/Ni@VCN electrodes were tested as anode for lithium-ion batteries,and the electrode featured outstanding lithium-storage capabilities with a high reversible capacity(1113 mAh g-1 after 100 cycles at 100 mA g-1),excel-lent long-term cycling stability(770 mAh g-1 after 500 cycles at 200 mA g-1),and good rate capability.The resulting electrode performance is one of the best Li-ion storage capabilities in the Ni3S2-type anode materials described.A unique"broccoli-like"structure of polycrystalline Ni3S2 capped on conductive VCN backbone helps the interface storage process and boosts lithium storage performance.
