Research progress in structural regulation of molybdenite electrode materials
摘要
Abstract
The commercial application of molybdenite in Li-ion battery was severely hindered by its low electronic conductivity and large volume change.Crystal regulation,size control and composite with carbon-based materials were used to solve the issues.Crystal regulation was converting the 2H phase of molybdenite to a 1T phase with metallic properties or expanding layer spacing to reduce the ion shuttle barrier.Size control reduced molybdenite's lateral and longitudinal dimensions by less layering treatment,increased reactive sites and shortened ion shuttle distances.The composite with carbon-based materials increased the electrical conductivity and reduced the volume expansion effect by using carbon materials'high conductivity and certain flexibility.The effects of crystal structure,morphology regulation and compound modification on the electrochemical performance of molybdenite were summarized,the development prospects in Li-ion battery were discussed.关键词
