Abstract
This paper reports the study results on R and D of redox flow battery for photovoltaic power generation in fiscal 1994. (1) On the production method of electrolyte, silica reduction treatment was attempted to use ammonium metavanadate recovered from boiler as electrolyte of redox flow battery. Silica removal rates more than 90% were achieved by crystallizing V as polyvanadate while keeping molten silica. It was ascertained in minicell experiment that trivalent and quadrivalent V electrolytes produced from recovered V are applicable to continuous charge/discharge operation for one week. (2) On development of battery systems, the relation between battery characteristics and physicochemical properties of carbon fiber electrodes was studied to improve carbon fiber electrodes. The efficiency of 80% was achieved at current density of 160mA/cm{sup 2} by use of layered electrodes, resulting in considerable cost reduction. Performance evaluation operation of the 2kW battery prepared in the last fiscal year was also carried out. 4 figs.
