摘要
锂离子电池是目前便携式电子设备中最流行的一种可充电电池。随着锂储量的消耗,锂离子电池的成本也在不断上升。钠离子电池可以作为一种替代技术,取代昂贵的锂离子电池。钠的来源非常丰富,因此钠离子电池可以比锂离子电池更便宜。许多用于锂离子电池的正极材料也作为钠离子电池的正极材料进行了测试。本研究以磷酸钴钠为阴极材料制备钠离子电池为研究对象。阴极材料采用氧化钴(II)和磷酸钠之间的简单固相反应制备。用粉末XRD对制备的材料进行了表征。采用充放电循环、循环伏安法分析、阻抗曲线匹配获得等效电路等方法对制备的阴极在电池中的性能进行了分析。阴极的放电容量为9.58 mA h g-1。循环伏安曲线表明,电池循环过程中存在氧化还原过程,但电池循环过程并非完全可逆。关键词:可充电电池,氧化钴钠,循环伏安法,充放电循环。
Development of Sodium-Ion Rechargeable Battery Using Sodium Cobalt Phosphate Cathode
Lithium-ion batteries are the most popular kind of rechargeable batteries accommodate in portable electronic devices up to date. As the Lithium deposits are depleting the cost of Lithium-ion batteries is increasing. Sodium- ion batteries can be introduced as an alternative technology which can replace expensive Lithium-ion batteries. Sodium sources are highly abundant and therefore Sodium-ion batteries could be made cheaper than Lithium-ion batteries. A number of cathode materials which were accommodated in Lithium-ion batteries have also been tested as cathode materials for Sodium-ion batteries. This research was based on a Sodium-ion battery which cathode was prepared using Sodium cobalt phosphate. The cathode material was prepared using a simple solid-state reaction between Cobalt (II) oxide and Sodium phosphate. The prepared material was characterized using powder XRD. Chargedischarge cycles, cyclic voltammetry analyzing, impedance curve matching to obtain equivalent circuit was used in order to analyze the performance of the prepared cathode in the battery. The discharge capacity of the cathode was calculated as 9.58 mA h g-1. The cyclic voltammetry curve has shown that an oxidation and reduction processes involved in the battery cycle but the battery cycle was not completely reversible.
