The past decade has witnessed a rapidly growing interest toward sodium ion battery (SIB) for large-scale energy storage in view of the abundance and easy accessibility of sodium resources. Key to addressing the remaining challenges and setbacks and to translate lab science into commercializable products is the development of high-performance anode materials. Anode materials featuring combined conversion and alloying mechanisms are one of the most attractive candidates, due to their high theoretical capacities and relatively low working voltages. The current understanding of sodium-storage mechanisms in conversion-alloying anode materials is presented here. The challenges faced by these materials in SIBs, and the corresponding improvement strategies, are comprehensively discussed in correlation with the resulting electrochemical behavior. Finally, with the guidance and perspectives, a roadmap toward the development of advanced conversion-alloying materials for commercializable SIBs is created.

Glasses are promising anode materials for Li-ion batteries (LIBs) owing to their unique open network structures and the absence of grain boundaries. Upon discharging/charging, both the capacity and cycle life of the glass anodes can be affected through their structural evolutions. This review article highlights the recent research advances in improving and understanding the electrochemical performances of various types of glass anodes. Both the SnO-and GeO 2 -based glass anodes suffer from the high initial capacity loss and short cycle life. The origin of the first-cycle irreversible capacity loss is discussed primarily from the structural evolution with cycles, that is, forming metallic Sn/Ge in the glass matrix. Recently, significant breakthroughs have been achieved in enhancing cycling stability and capacity of the anode materials by means of the disorder-order engineering with respect to the V 2 O 5 -TeO 2 glass systems. In addition, the most recent advances in the applications of dual-phase glass anodes in LiBs are reviewed. This article gives an overview of the applications of the glass anodes, as well as deals with the structural factors affecting their electrochemical performances. A deeper understanding of these factors will enable further steps toward improvement and application of the glass anodes for LIBs.
