Properties and performance evaluation of hydrocarbon-based membrane for redox flow battery |
| 초록 |
Recently, redox flow battery (RFB) in energy storage system with high-capacity has been actively reseaching and developing. Economical hydrocarbon membranes alternative to fluorinated membranes for RFB membrane are receiving attention. In this study, characteristics of brominated and sulfonated poly(phenylene oxide) (bsPPO) were compared with expensive fluorinated membrane at VRFB (Vanadium Redox Flow Battery) unit cell operation condition. Permeability of vanadium ion through membrane, ion exchange capacity (IEC), change of OCV, swelling, charge-discharge curves and energy efficiency were measured. bsPPO membrane showed lower permeability of vanadium ion, higher IEC and then higher energy efficiency compared with Nafion 212 membranes. |
