Development of vanadium redox flow battery for photovoltaic generation system

Book ·
OSTI ID:208219
Photovoltaic power generation system (PV) requires a battery for night and rainy day. A redox flow battery has advantage over a lead acid one on this application for the capability of deep discharge and needlessness of equalized charge. The authors have developed the high performance vanadium redox flow battery for this purpose and inexpensive production technology of electrolyte which occupies the majority in the battery cost by chemical reduction from boiler plant by-product. The 2 kW (10 kWh) battery, the minimum unit for practical size battery (50 kW x 50 h), achieved 1.2 kW/cm{sup 2}-electrode area at the 100 mA/cm{sup 2} current density.
