Abstract

Disclosed are a method and apparatus for analyzing an electrolyte of a redox flow battery. The method includes passing a first electrolyte solution or a second electrolyte solution through each of a first auxiliary cell and a second auxiliary cell connected to a main cell and a storage tank, closing at least one of the first auxiliary cell and the second auxiliary cell, applying current to the first auxiliary cell and the second auxiliary cell; creating data by measuring a voltage between the first auxiliary cell and the second auxiliary cell, and analyzing an electrolyte contained in the electrolyte solution in the first auxiliary cell or the second auxiliary cell based on variation in the voltage between the first auxiliary cell and the second auxiliary cell according to time. According to the present invention, information on an electrolyte can be obtained more efficiently and easily.

Description

technical field [0001] The present invention relates to a method and apparatus for analyzing an electrolyte of a redox flow battery, and more particularly, to a method and apparatus for analyzing the amount and oxidation number of an electrolyte contained in an electrolyte solution of a redox flow battery . Background technique [0002] A typical secondary battery converts input electrical energy into chemical energy, stores the converted chemical energy through charging, converts the stored chemical energy into electrical energy, and outputs the converted electrical energy through discharging. [0003] Like a typical secondary battery, a redox flow battery converts input electrical energy into chemical energy, stores the converted chemical energy by charging, converts the stored chemical energy into electrical energy, and outputs the converted electrical energy by discharging. However, since a redox flow battery is different from a typical secondary battery in that an elec...
