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

Abstract

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.
