Research Progress on the Modification Strategies of MoO3 Electrode Materials
Numerous new materials have been researched to replace the conventional electrode materials for energy storage systems in order to satisfy the expanding demands of the electronics market.MoO3 is an electrode material with a higher theoretical capacity than graphene,which is widely used in metal-ion batteries and supercapacitors.However,the poor intrinsic lithium ion/electron conductivity and the severe bulk effect during the conversion reaction of MoO3 severely limit the practical application of MoO3.The electrochemical performance of MoO3 electrode materials can be improved by optimisation strategies such as designing nanostructures,compositing with highly conductive substances,forming oxygen vacancy defects,intercalation composites and doping.The main preparation methods of MoO3 electrode materials are reviewed,the optimisation methods of MoO3 electrode materials are summarised,and the future research work on MoO3 electrode materials is prospected.
