摘　　要：水系锂离子电池是以水溶液为电解质的二次电池,它克服了传统有机体系电池电解液昂贵、有毒、易燃、离子电导率低、制作成本高等缺点,成为继风能、太阳能后最具发展潜力的绿色能源之一。本文归纳了近年来国内外水系锂离子电池正负极材料的研究进展,介绍了各种电极材料存在的主要问题(如电极材料在电解液中的溶解、电解液中质子活性大导致电极材料发生副反应等)以及改性方法,并提出对电极材料进行修饰是水系锂离子电池未来的发展趋势。Aqueous lithium-ion batteries as secondary batteries use aqueous solutions as electrolytes. Such batteries have a great potential for effective use of renewable energy such as wind and solar power because of advantages of low production costs, low toxicity, non-flammability and high ionic conductivity. This paper summarises recent progress in electrode materials （anode and cathode electrodes） for aqueous lithium-ion batteries. Key issues associate with dissolution of electrode materials in electrolytes and side reactions due to active protons in the electrolytes are highlighted and methods of modifying electrode materials are discussed. Future research questions are also outlined.
