dc.description.abstract | For advanced high-performance lithium-ion batteries (LIBs), a novel anode material with a high capacity needs to be developed. In particular, molybdenum disulfide (MoS2) with a layered structure consisting of S-Mo-S formed by van der Waals force exhibits a high theoretical capacity (1280 mAh g(-1)). In this study, MoS2-TiN electrodes were fabricated using a radio frequency (RF) magnetron sputtering deposition method by which MoS2 and TiN sputtering targets could be individually controlled. As the RF power of the TiN target increased (20, 40, 60 W), the ratio of Ti in the electrodes increased and the ratio of Mo in the electrodes decreased. In particular, compared to pure MoS2, the MoS2-TiN with an optimum amount of TiN exhibited a high discharge capacity for 300 cycles and an improved high-rate cycling performance, i.e. an initial discharge capacity of 789.2 mAh g(-1) with the maintained capacity of similar to 700 mAh g(-1) for 300 cycles. This demonstrates that TiN in the MoS2-TiN could reduce the volumetric variation caused by the conversion reaction of MoS2 and assist in the improvement of the electrodes. (C) 2018 Elsevier B.V.
