Chalcogenides metal-based heterostructure anode materials toward Na^(+)-storage application

Sodium-ion batteries(SIBs)are promising candidates for future large-scale energy storage systems due to their low cost and high safety.However,the sluggish kinetics caused by the large radius of Na+impedes the practical application of SIBs.Heterostructure engineering has emerged as an attractive strategy to alleviate this critical issue due to its intriguing contributions to accelerating electrons/ions transfer kinetics,improving structural stability,and enhancing Na^(+)adsorption ability.From this perspective,in this review,we introduce the vital role of heterostructure on the performance of SIBs firstly.The commonly used approaches for synthesizing chalcogenides metal-based heterostructure anodes are then presented.Subsequently,we discuss the recent progress of various chalcogenides metal-based anodes in detail.Finally,we provide a concluding discussion on the current challenges and perspectives of future development of the heterostructure anode materials for high-performance SIBs.
