ELECTRODE FOR REDOX FLOW BATTERY, FABRICATION METHOD THEREOF, APPARATUS AND METHOD FOR FABRICATING ELECTROLYTE FOR REDOX FLOW BATTERY, DEVICE AND METHOD FOR MEASURING SELECTED ION CONCENTRATION OF ELECTROLYTE, AND STAND-ALONE BATTERY SYSTEM
The present invention relates to a redox flow battery and a redox battery system, and more particularly, to an electrode constituting a redox flow battery, a method of fabricating the electrode, an apparatus and method for fabricating electrolyte for a redox flow battery, a device and method for measuring a selected ion concentration of electrolyte constituting a redox flow battery, and a stand-alone redox battery system. A stand-alone redox battery system according to the present invention includes a micro hydroelectric power generating device and a redox battery. The micro hydroelectric power generating device includes: a feathering paddle wheel that is rotated by water introduced through a conduit; and a direct current generator that generates direct current according to the rotation of the feathering paddle wheel. The redox battery includes: a stack-type electrode assembly having a stacked structure of unit electrodes; a first electrolyte tank and a second electrolyte tank, which store, respectively, active materials having different oxidation levels; and a first pump and a second pump, which are connected to the first electrolyte tank and the second electrolyte tank, respectively, to circulate the stored active materials through the stack-type electrode assembly, thereby performing charging and discharging operations.
