碳纤维织物基MoS2柔性电极的制备及其电化学性能
Preparation and electrochemical performance of a flexible MoS2 electrode based on carbon fiber fabric
摘要
Abstract
In order to expand the smaller interlayer spacing of molybdenum disulfide(MoS2)and enhance its storage performance as a cathode material in aqueous zinc ion batteries,a high-conductivity carbon fiber fabric was used as a flexible loading substrate for MoS2.By employing ammonium bicarbonate and sodium bicarbonate as two phase-regulating agents in the synthesis process of MoS2,different interlayer embedded structures of MoS2 materials(MoS2-NH4+and MoS2-Na+)were obtained.The study investigated the influence of embedded ion types on the interlayer structure and zinc ion storage characteristics.Test results indicate that the NH4 ions released by ammonium bicarbonate during the reaction(expanding the layer size by 0.39 nm)exhibit better interlayer expansion effects compared to the Na1 ions released by sodium bicarbonate(expanding the layer size by 0.12 nm).Under a current density of 500 mA·g-1,the MoS2-NH4+electrode maintains a capacity retention rate of up to 97.39％after 300 cycles and demonstrates excellent operational characteristics in subsequent flexible fiber-shaped battery applications.The proposed method for preparing high-performance MoS2-based flexible electrode materials in this study opens up new avenues for the structural optimization design of flexible electrode materials for zinc ion batteries.关键词
