    摘要： The present invention relates to an electrolyte storage unit applicable to redox flow batteries and a vanadium redox flow battery including the same. The electrolyte storage unit for redox flow batteries of the present invention can be useful in minimizing a contact area of an electrolyte with the air to improve a self-discharge phenomenon of a battery and solving a problem such as an imbalance between a concentration and a volume of the electrolyte, which is caused during battery driving. Accordingly, a cycle of a process of regenerating an electrolyte can be delayed, and capacity and lifespan characteristics of the battery can be improved. Also, the electrolyte storage unit of the present invention can be easily handled and installed because electrolytes may not be easily mixed even by external impact.

    摘要： The present invention relates to a bipolar plate with fibrous conductive materials inserted into the flow path and a redox flow battery including the bipolar plate.It is possible to realize the redox flow battery having an excellent energy efficiency while improving the charging/discharging capacity and efficiency regardless of the flow rate of the electrolyte solution, by increasing the retention time of the electrolyte solution in the flow path by the fibrous conductive materials to increase the chance of reaction with the electrode layer.
