摘要
在众多电化学储能技术中,室温钠离子电池除具有能量密度高、循环寿命长的特点外,还具有其他电池体系所不具有的资源丰富和成本低廉的优势,是一种较理想的规模储能电池体系.中国科学院物理研究所自2011年以来致力于低成本、安全环保的钠离子电池技术的研发,在正、负极材料和电解质材料开发中取得了多项原创性的研究成果,并研制出Ah级钠离子软包电池.例如,首次发现Cu^(2+)/Cu^(3+)氧化还原电对高度可逆并设计了Na-Cu-Fe-Mn-O基低成本层状氧化物正极材料;首次通过简单的一步碳化法制备出性价比高的无烟煤基负极材料;首次将一种新型的钠盐NaFSI应用于碳酸酯非水电解质以大幅度提升电极材料的性能等.本文综述了物理所在钠离子电池材料及器件研究中所取得的重要进展和突破,期待经过进一步不懈地努力为实现钠离子电池的产业化做出重要贡献.
Among various electrochemical energy storage technologies, room-temperature Na-ion batteries （NIBs） are regardedas ideal candidates in large-scale energy storage field due to advantages of abundant resources and low material cost in addition to their characteristics of high energy density and long cycle life. Since 2011, the Institute of Physics, Chinese Academy of Sciences （IOP-Chinese Academy of Sciences） has devoted to developing the cost-effective and environmental- safe NIBs, and attained many original achievements in the research of cathode, anode and electrolyte materials, and also developed Na-ion pouch cells with capacities of 〉 1 Ah. For instance, the highly reversible Cu2＋/Cu3＋ redox was discovered for the first time and the low cost Na-Cu-Fe-Mn-O layered oxide cathodes have been designed accordingly; the anthracite-derived carbon anodes have been exploited via a simple one-step carbonization process with a high performance-to-price ratio; a new type of NaFSI sodium salt was first used in the non-aqueous carbonate electrolyte to significantly improve the performance of electrode materials, etc. This review summarizes the important progress and breakthroughs achieved in IOP-Chinese Academy of Sciences for materials and devices of NIBs. We hope that these contributions conduce to realizing the industrialization of NIBs.
