钠离子电池负极材料的研究与发展

Research and Development of Sodium Ion Batteries

钠与锂是同属第一主族的两种元素,二者化学性能相似,因钠相对锂在成本和储存需要方面都有明显优势,使得钠离子电池是极具潜力的锂离子电池替代品.为获得更为优异的电化学性能,钠离子电池负极储能材料的选用则显得尤为关键.随着钠离子电池研究的逐步推进,用于钠离子电池的负极储能材料也取得突破性进展,基于研究现状对金属化合物、碳基材料、合金材料、非金属单质四类常见负极材料研究进展进行了综述.

The two elements sodium and lithium belong to the same group,and their chemical properties are similar.Moreover,sodium has obvious advantages over lithium in terms of cost and storage requirements,which makes sodium ion battery a potential lithium ion battery complementary product.In order to obtain more excellent electrochemical performance,the selection of sodium ion battery anode energy storage material is particularly critical.With the progressive advancement of the research on sodium ion batteries,a breakthrough has been made in the anode energy storage materials for sodium ion batteries.Based on the current research status,the research progress of four common anode materials,namely metal compounds,carbon-based materials,alloy materials and non-metallic elemental materials,is reviewed.
