摘要
Transition-metal selenides(M_xSe_y,M = Fe,Co,Ni)and their composites exhibit good storage capacities for sodium and lithium ions and occupy a unique position in research on sodium-ion and lithium-ion batteries.MxSey and their composites are used as active materials to improve catalytic activity.However,low electrical conductivity,poor cycle stability,and low rate performance severely limit their applications.This review provides a comprehensive introduction to and understanding of the current research progress of M_xSe_y and their composites.Moreover,this review proposes a broader research platform for these materials,including various bioelectrocatalytic performance tests,lithium-sulfur batteries,and fuel cells.The synthesis method and related mechanisms of M_xSe_y and their composites are reviewed,and the effects of material morphologies on their electrochemical performance are discussed.The advantages and disadvantages of M_xSe_y and their composites as well as possible strategies for improving the storage and conversion of electrochemical energy are also summarized.
