摘要
钒电池作为一种清洁、高效的储能装置,发展潜力巨大,其中电堆、电解液是钒电池最重要的组成部分,直接关系到钒电池直流侧能量转化效率.但是目前市场上的钒电池电堆、电解液种类多、差异化大,造成部分钒电池储能项目能量转化效率性能不理想.通过对市场上成熟的电堆、电解液产品进行适配性测试,在额定恒功率模式、80％额定恒功率模式、140 mA/cm2电流密度恒电流模式、170 mA/cm2电流密度恒电流模式四种充放电测试模式下进行分析,匹配出最佳的钒电池电堆、电解液组合,为电池电堆与电解液适配性研究提供参考.
Abstract
Vanadium batteries,as a clean and efficient energy storage device,have great potential for development.Among them,the stack and electrolyte are the most important components of vanadium batteries,which directly affect the energy conversion efficiency of the DC side of vanadium batteries.However,the wide variety and differentiation of vanadium battery stacks and electrolytes in the current market have resulted in unsatisfactory energy conversion efficiency performance for some vanadium battery energy storage projects.By conducting compatibility tests on mature stack and electrolyte products in the market,analysis was conducted in four charging and discharging test modes:rated constant power mode,80％rated constant power mode,140 mA/cm2 current density constant current mode,and 170 mA/cm2 current density constant current mode.The optimal combination of vanadium battery stack and electrolyte was matched to provide reference for the research on the compatibility of battery stack and electrolyte.
