摘要:

钠离子电池由于其资源丰富、价格低廉等因素常被用作锂离子电池的替代品。但由于钠的原子半径相对较大、动力学性能相对迟缓等问题,限制了钠离子电池的商业化发展进程。本文基于目前最新的研究,系统总结了普鲁士蓝类、层状过渡金属氧化物类、聚阴离子类中的磁性金属元素在钠离子电池正极材料中的应用,通过掺杂磁性元素来提高电化学性能及循环稳定性。普鲁士蓝类在实际应用中普遍存在容量利用率低、效率低、倍率差和循环不稳定等缺点,然而通过磁性金属元素的掺杂降低Na+通过SEI膜的扩散电阻,加速离子扩散过程,增加活性位点。层状过渡金属氧化物类、聚阴离子类正极材料利用磁性金属元素,增强了钠离子电池的电化学性能。对比锂离子电池负极材料,通过设计含有磁性元素的新型钠离子电池负极材料实现快速储钠,在碳基材料中负载磁性金属元素,加速Na+扩散。本文对最新的进展情况进行分析并综述。

Abstract:

Sodium ion batteries (SIBs) are often used as substitutes for lithium ion batteries due to their abundant resources and low prices. However, due to the relatively large atomic radius of sodium and the relatively slow kinetic performance, the commercialization of sodium ion batteries has been limited. Based on the latest research, this article systematically summarizes the application of magnetic metal elements in Prussian blue, layered transition metal oxides, and polyanions in the cathode materials of sodium ion batteries, and improves electrochemical performance and cycle stability by doping magnetic elements. In practical applications, Prussian blues generally have shortcomings such as low capacity utilization, low efficiency, poor magnification, and unstable circulation. However, doping with magnetic metal elements reduces the diffusion resistance of Na+ ions through SEI films, accelerates the ion diffusion process, and increases active sites. Layered transition metal oxide and polyanion cathode materials utilize magnetic metal elements to enhance the electrochemical performance of sodium ion batteries. Compared to lithium ion battery anode materials, a new type of sodium ion battery anode material containing magnetic elements was designed to achieve rapid sodium storage. Magnetic metal elements were loaded into carbon based materials to accelerate the diffusion of Na+ ions. This article analyzes, summarizes, and summarizes the latest developments.
