摘要
钠和锂具有相似的物化性质,由于钠在地壳中资源丰富且成本低廉,成为非常有发展潜力的电池体系,近年来得到了国内外研究人员的广泛关注。首先在分析钠离子电池工作原理的基础上,可知钠离子可以提高电极的反应动力学速率,表现出较小的电荷转移阻抗,较锂离子电池具有电化学反应过程中反应动力学较快的优势。然后,从原材料成本、矿产储量和电芯成本3个方面分析了钠离子电池用于电网储能的成本优势。最后,重点分析了钠离子电池应用于电网储能面临的障碍,并对未来的研究和发展方向进行展望。
Sodium has similar physical and chemical properties to lithium,and is rich in resources in the earth's crust with low cost.It has become a potential battery system,and has been widely concerned by researchers at home and abroad in recent years.Firstly,based on the analysis of the working principle of sodium⁃ion battery,it was concluded that sodium ion can improve the re⁃action kinetics rate of electrode,showing a smaller charge transfer impedance and faster reaction kinetics than lithium battery.Then,the cost advantage of sodium ion battery for grid side energy storage was analyzed from three aspects of raw material cost,mineral reserves and cell cost.Finally,the obstacles faced by the application of sodium⁃ion battery in grid side energy storage were analyzed,and the future research and development direction were prospected.
