摘要
随着人们对新能源和环境的重视,锂离子电池的应用逐渐扩展到电动汽车和储能领域,这势必增加了锂资源的使用和消耗。在锂资源日益紧缺的形势下,锂离子电池原材料成本必然难以降低,使其在大规模储能中的应用受到限制。而室温钠离子电池由于其资源丰富、成本低、能量转换效率高、循环寿命长、维护费用低等诸多优势已成为目前研究的热点。本文对室温钠离子电池材料选择和原材料成本进行了分析,并与当前常用的锂离子电池体系进行对比,从电池经济性角度表明室温钠离子电池是大规模储能领域的优秀备选电池。
With the emphasis on new energy and environment, the application of rechargeable lithium-ion batteries is gradually expanding in the field of electric vehicles and energy storage, which is bound to enhance lithium resource consumption. Under the current situation of the increasingly scarce lithium resources, it is inevitably so difficult to reduce the raw materials cost of lithium-ion batteries, which probably limits their large-scale application in energy storage. Nowadays, room-temperature sodium-ion batteries for large-scale energy storage have become a research hot topic due to a great deal of advantages such as abundant resources, low price, high energy conversion efficiency, long cycle life and low maintenance cost. In this work, analyses are carried on the electrode material selection and raw materials cost for room-temperature sodium-ion batteries in comparison with common lithium-ion battery systems. The results indicate that room-temperature sodium-ion batteries are promising alternatives in the field of large-scale energy storage from the viewpoint of battery economic perspective.
