The Kansai Electric Power Co. and Sumitomo Electric have been jointly developing a Redox Flow battery,a type of storage battery used for load-leveling purposes. In 1989, a 60kW-class system using iron/chromium electrolyte was constructed and subsequently tested for about five years, achieving 1,819 charge/discharge cycles compared to the target of 1,500 cycles. Then a battery using vanadium electrolyte to provide a greater electromotive force than the conventional iron/chromium electrolyte was developed in order to achieve greater compactness and to reduce application costs. This battery was evaluated using a 20kW-class battery to perform 13,342 charge/discharge cycles, and satisfactory results were obtained. Last year a 450kW system as the basic unit for practical implementation was installed at the Kansai Electric Power Company's Tatsumi substation, where the system is currently being tested (241 charge/discharge cycles as of Setember 1997). This report covers the principles and configuration of the Redox Flow battery, the test results of the 20kW-class battery, and the 450kW system.
