An all-vanadium redox battery possesses many advantages over conventional storage batteries. This paper takes the graphite felt(GF) as raw material,by using H2O2 as the oxidising agent,which aims to research the effect of temperature and time on water bath heating in a fixed dimensional graphite felt condition. Performance index of SEM, IR and electrochemical properties of graphite felt,modified by SnO2, were investigated by cyclic voltammetry method. The results showed that,when using graphite felt electrode that oxided by H2O2, the electrochemical performances would be the best and the conditions were as follows,the water bath temperature was 95¡æ£¬the water bath heating time was 4h. The analysis of SEM ,IR and electrochemical properties showed that ,electrochemical performance improved when graphite felt electrode modified by SnO2 |
