| Abstract: | Molybdenum disulfide (MoS2) was loaded on biocarbon using waste camellia dregs (CDs) as the carbon source, which was further coated with dopamine hydrochloride to construct biocarbon/MoS2 electrode composites. The electrochemical lithium storage performance of the composites with different MoS2 contents was investigated. SEM results demonstrated that the composite had a three-dimensional foam-like structure with MoS2 as the interlayer. XRD and HRTEM tests revealed that MoS2 interlayer spacing in the composite was expanded. XPS analysis showed that new Mo—N bonds were formed in the active material. The electrochemical tests showed that the composite with a MoS2 content of 63% had a high initial specific capacity of 1434 mA·h/g at a current density of 100 mA/g. After a long cycle at a high current, it also showed good cycling stability and the capacity retention was nearly 100%. In addition, it had good lithium ion deintercalation ability in the electrochemical kinetics test. |
