钠离子电池硫化物负极材料的研究进展
Recent research progress of metal sulfides as anode materials for sodium-ion batteries
摘要
Abstract
The application of metallic sulfide in sodium-ion battery is reviewed. Sodium and lithium are of the same group, and sodium ion battery is expected to be a promising energy storage device like lithium-ion battery. Therefore, its electrode materials is the current research hotspot. The current problems of these materials are introduced. The large radius of sodium ions leads to difficult intercalation/deintercalation of Na+ for in the electrode materials, and volume expansion etc. In view of good sodium-intercalation platforms of layered metal sulfides, they have attracted extensive attention from researchers. Summarized the electrochemical properties of the molybdenum disulfide, tungsten disulfide, tin disulfide, vanadium disulfide, titanium disulfide several layered transition metal disulfide and nickel sulfide, zinc sulfide, copper sulfide, several kinds of non-disulfide anode materials in sodium-ion batteries, including the capacity and cycle performance etc, Volume expansion、slow diffusion of Na+、low efficiency of charge and discharge、polysulfide dissolving-shuttling of the main problems faced by these materials at present are analyzed. It is pointed out that the methods to alleviate the volume expansion of sulfides are carbon composite, nano-materials, morphology control etc. For l①aye red transition metal disulfides. the electr ochemical performance can be improved by enlarging theinterlayer spacing and adjusting the cut-off voltage. Finally, the research prospect of transition metal sulfide anode materials is viewed.关键词
