Synthesis Of Zirconium Disulfides And Their Applications In Lithium Ion Battery

High performance lithium batteries are in great demands for consumer electronics,electric vehicles and grid scale stationary energy storage.It has been reported that layered transition metal sulfides exhibited much better cycling performance than other metal sulfides that are not based on the layered structure.Layered MoS₂ and ZrS₂ are structurally similar to graphite,which are considered as the first choice for next-generation lithium-ion battery electrode materials.In this work,ZrS₂,MoS₂/ZrS₂ and LiFePO₄/C have been synthesized via several different methods,the physical and electrochemical properties of the synthesized samples were characterized and tested by XRD,SEM,CV,EIS,EDS,and charge-discharge measurement,and the effect of structures and morphology on electrochemical properties have been analyzed.As-prepared ZrS₂ and MoS₂/ZrS₂ composites showed a excellent cycling performance and rate capability in the cut-off voltage 0.01-3.0 V.
