摘要
与锂元素比较,钾元素资源丰富,价格低廉,且物理化学性质与锂元素和钠元素相似,因此钾离子电池已成为取代成本相对较高的锂离子电池的最佳选项之一,近年来受到了广泛的关注。普鲁士蓝及其类似物(PBAs)具有开放的框架结构,给半径较大的钾离子提供了便捷的扩散通道,这一特点使普鲁士蓝及其类似物成为了钾离子电池正极材料的理想候选者。本文系统介绍了近年来国内外关于普鲁士蓝材料做为钾离子电池正极材料方面的研究进展,包括在有机系钾离子电池和水系钾离子电池中的应用情况,并对这类材料在钾离子电池正极材料中的发展前景、存在的问题及挑战做了分析和展望。
Potassium ions batteries(PIBs)have attracted great attention recently,due to the abundant resources,and the similar physicochemical properties of potassium to lithium and sodium.Prussian blue and its analogues(PBAs)has open-framework structure,which makes the intercalaltion/deintercalation of potassium ion with larger radius than lithium ions feasible.Actually,PBAs has been recognized as one of the most promising cathode materials for PIBs.In this paper,we introduce the progress on the researches for PBAs as cathode of PIBs systematically,including in non-aqueous batteries and aqueous batteries.Furthermore,we also analyze the problems and challenges existed for the application of PBAs materials in PIBs and prospect the future of PBAs in potassium-ion batteries.
