全钒氧化还原液流电池石墨棒电极的性能研究
Study on graphite rod electrode for all vanadium redox flow battery
摘要
Abstract
In this report, the different brands of wasted battery's graphite rod electrodes were used as working electrodes to study the electrochemistry performance with the circulation voltammetry method. The effects of the scanning velocity and times were investigated to examine the electrode's tolerance of voltage and electric current and the electric discharge performance. The results show that the 5#D graphite rod electrode has a tolerance of 1.65 V. In the same scanning potential range, the charge/discharge performance of large current was studied at different scanning speeds. The experiment proves that the 5'D graphite rod electrode still shows good electrochemical properties. In order to inspect the cyclic properties, the 5#D graphite rod electrode was tested with the circulation voltammetry method. After 100 times of scanning, the current conservation rate of the 5#D graphite electrode was still as high as 95%. The experiment results show that the 5'D graphite rod electrode has a relatively better electrochemistry performance which is suitable for the VO2+NC2+electrode's positive electrode material.关键词
