NiSnO3 nanoparticles/reduced graphene oxide composite with enhanced performance as a lithium-ion battery anode material

NiSnO3 nanoparticles (NPs) were loaded on reduced graphene oxide (RGO) by a facile hydrothermal technique as a anode material for lithium ion batteries (LIBs). It was found that the NiSnO3/RGO anode exhibits improved LIBs performance compared to bare NiSnO3 or RGO. The NiSnO3/RGO anode can maintain a reversible capacity of 792 mA h g(-1), tested at 1200 mA g(-1) after 60 cycles. When the current density was lowered in a test of rate capacity, the charge capacity was completely restored after high rate cycling at 6000 mA g(-1) and maintained 889 mA h g(-1) at 200 mA g(-1) after 115 cycles. The enhanced LIBs performance of the NiSnO3/RGO nanocomposites can be attributed to the synergistic effects between a highly loaded NiSnO3 NPs and graphene network.
