摘要
报道了一种新型移动式钠离子电池储能系统,其核心储能器件为钠离子电池,采用自制的NaNi_(1/3)Fe_(1/3)Mn_(1/3)O_2为正极材料,负极材料为硬碳。采用XRD、DSC等对正极材料的结构和热稳定性进行分析表征。设计制作了1 A·h软包型钠离子电池,对其电化学性能与安全性进行测试。在此基础上设计了钠离子电池包以及基于钠离子电池的0.1 kW·h新型移动式储能系统。该系统在家用储能、军事电源、低速电动车上有良好的应用前景。
A new portable energy storage device based on sodium-ion battery (SIB) has been designed and assembled. Layered oxide NaNix/3FeI/3Mn1/302 was used as cathode and hard carbon was used as anode. The structure and thermal stability of the prepared material were measured by using XRD and DSC techniques. Soft pack battery with 1 A.h capacity has been designed and the electrochemistry and safety performance were tested. SIB packs of 0.1 kW.h were fabricated for the new portable energy storage device. This sodium ion energy storage device has a promising perspective on household electrical energy storage, military power supply, smart grid, low-speed electric vehicle, etc.
