可充镁离子电池研究发展现状

Research progress on rechargeable magnesium-ion batteries

摘要:

与锂离子电池相比，镁离子电池因具有能量密度高、价格低廉，使用及操作安全以及环境友好等性能而被广泛关注，使得可充镁电池在大负荷储能方面具有十分广泛的用途和良好的发展前景。但目前现镁离子电池的电解液与电极材料的相互兼容性还没有达到较为理想的状态；因此，开发高稳定正极材料和宽电压窗口及无钝化电解质是促进镁离子电池产业化应用的关键。本文对国内外可充镁电池的研究发展现状进行归纳分析，尤其是从目前两大研究热点正极材料和电解质予以系统综述，总结了研究存在的问题并对其发展方向做了展望。

Abstract:

Compared with lithium-ion batteries, magnesium-ion batteries have been widely concerned due to their good merits of high energy density, low price, highly safe usage and operation, and environmentally-friendly type. Rechargeable magnesium batteries are believed to be very promising in the application of large load energy storage. However, the compatibility between electrolyte and electrode material of magnesium-ion battery has not reached a relatively ideal state. Therefore, the development of high stable cathode materials, wide voltage window and non-passivating electrolytes are the keys to promoting the industrial application of magnesium-ion batteries. In this paper, the research status at home and abroad about rechargeable magnesium-ion batteries are reviewed systematically through the review-analysis of the published peer articles. The research progress on the battery system’s main components including cathode materials and electrolytes are elaborated in detail. This review paper also discusses the existing problems of rechargeable magnesium-ion batteries, and provides summary and prospective for their development direction.
