钠离子电池电极材料资源丰富，价格低廉. 然而，现阶段钠离子电池电极材料的性能还不理想，开发合适的电极材料是实现髙容量、长循环寿命钠离子电池的关键. 本文将以作者近期的研究工作为主，着重讨论几种微/纳米材料作为钠离子电池电极的性能及作用机理，并展望其今后的发展趋势.

Sodium has similar physics and chemical properties to lithium, alternatively, sodium (Na)-ion batteries have again aroused a great deal of interest recently, particularly for large-scale stationary energy storage applications due to the practically infinite sodium resources and low cost. However, the technics and materials for Na-ion batteries are immature. Therefore, development of advanced anode and cathode materials for Na-ion batteries is urgently desired but remains a great challenge. This paper briefly reviews some recent progresses in this field, addressing the morphology effects, as well as functions of carbon composite materials toward Na-ion batteries. Several electrode materials with micro/nano-structures based on the work of the authors are highlighted for illustration.
