摘要： 双极板作为液流电池的关键材料之一,起到连接电池内部不同单电池的正极和负极,导通电池内电路,阻隔双极板两侧电解液相互渗透的重要作用.根据双极板材料的不同,可以分为金属板,石墨板与复合材料板.复合材料板克服了金属板,石墨板的缺点,耐腐蚀性强,机械强度好,能够满足液流电池的需要.碳纤维具有良好的导电性,力学性能和化学稳定性,通过加入碳纤维来改善双极板的性能,成为了研究人员常用的方法.本文综述了近年来国内外主要的碳纤维增强型复合材料双极板的研究成果,对不同的方法进行了比较,并指出了碳纤维增强型复合材料双极板的发展趋势.

Abstract: Bipolar plates served as one of the key components for flow batteries plays an important role in connecting the positive and negative electrodes and physically separated the electrolyte in the neighboring chambers. The types of bipolar plates reported before included metal plates, graphite plates and composite plates. Composite plates meet the demands of the flow batteries and meanwhile they overcome some shortcomings of metal plates and graphite plates. Carbon fiber has various advantages including good conductivity, mechanical strength and chemical stability. And herein the method of adding carbon fiber into bipolar plates is attracting more and more researchers to improve the performance of the bipolar plates. This paper reviews the recent major research results of employing carbon fiber to reinforce the performance of composite bipolar plates. Moreover, various methods are compared and proposed to the development tendency of reinforcing the properties of composite bipolar plates with carbon fiber.

Key words: flow battery, bipolar plate, composite materials, carbon fiber
