Amorphous NiMo3S13/nickel foam integrated anode for lithium-ion batteries

Although crystalline anode materials with long-range ordered lattice structure are in favor of facilitating the electron transfer, their structures are easily disrupted during long-term cycling due to the continuous embedding/de-embedding of lithium ions. In contrast, the amorphous materials have abundant defects and lithium ion storage sites, reflecting a superior reaction kinetics and long-term cycling stability. Here, we synthesize an integrated hybrid anode by in-situ loading amorphous NiMo3S13 nanosheets on nickel foam substrate. Benefiting from the introduction of Ni2+ that amorphizes the molybdenum-sulfur clusters, the assembled lithium ion battery based on the integrated NiMo3S13/nickel foam anode delivers a specific capacity up to 1659 mA center dot h center dot g(-1) at a current density of 0.6 A center dot g(-1) and exhibits superior rate/cycling performance.
