dc.description.abstract | Lithium-oxygen batteries (LOBs) are considered as next-generation energy storage systems owing to their high energy densities. In order to achieve high-performance LOBs, it is necessary to develop efficient electrocatalysts that exhibit reversible formation and decomposition of discharge products on the oxygen-electrode side. In this study, single-crystalline NiS2 nanosheets (NiS2-NSs) are fabricated as an efficient electrocatalyst in an oxygen-electrode for high-performance LOBs. Ni(OH)(2)-NSs are prepared through a hydrothermal reaction and subsequently reacted with sulfur by a solid/gas phase reaction process to form NiS2-NSs. As an electrocatalyst in an oxygen-electrode, the single-crystalline NiS2-NSs can reversibly form and decompose the discharge products during the discharging and charging processes, respectively. In particular, the NiS2-NSs more effectively decompose the discharge products compared to the Ni(OH)(2)-NSs owing to its high affinity to oxygenated species. In addition, the NiS2-NSs exhibit a long-term cyclability over 300 cycles at a current density of 1000 mA g(-1) with a cut-off capacity of 1000 mA h g(-1). Moreover, NiS2-NSs without conducting agent exhibit an electrocatalytic activity and its LOB performance can be further maximized through addition of a redox mediator. | - |
