摘要: 钠离子电池具有钠资源存储丰富、价格低廉等优点,是一种极具发展前景的储能装置,因此成为当下研究热点。钠离子电池的电化学性能主要取决于正负极材料。但是,钠离子较大的半径使其在电极材料中可逆地嵌入/脱出更为困难。而金属化合物材料作为储钠负极材料时,遵循转化反应机制,并表现出较高的理论比容量,因而受到研究人员的广泛关注。本文综述了金属氧化物、金属硫化物、金属磷化物等几种金属化合物负极材料的储钠机制和研究进展,探讨了金属化合物材料的储钠性能,阐明了金属化合物作为理想的储钠负极材料的优势,最后对金属化合物材料的研究前景进行了展望。

Abstract: Sodium-ion batteries have attracted much attention as a type of promising energy storage system due to the abundant resources and low-cost of sodium. However, the larger radius of Na+ leads to a more difficult reversible intercalation/deintercalation of Na+ in electrode materials. Recently, metal compounds have been intensively investigated as anode materials for sodium-ion batteries with high theoretical capacities due to their conversion reaction mechanism of sodium storage. This paper summarizes the sodium-storage mechanism and research progress of metal compounds including oxides, sulfides and phosphides, investigates the sodium-storage performance, reveals the advantages of metal compounds as promising anode of sodium-ion batteries, and prospects the development of metal compound anodes for sodium storage.

Key words: sodium-ion battery, anode materials, metal oxides, metal sulfides, metal phosphides
