Title:
REDOX FLOW BATTERY, REDOX FLOW BATTERY ELECTRODE, AND ELECTRODE CHARACTERISTIC EVALUATION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/119110
Kind Code:
A1
Abstract:
Provided are: a redox flow battery having a low internal resistance; an electrode used in the redox flow battery; and an electrode characteristic evaluation method such that the electrode characteristics can be evaluated simply and accurately. The redox flow battery comprises, layered therein, one or more sets of an electrode set containing a positive pole electrode and a negative pole electrode carrying out a battery reaction by being supplied with an electrolytic solution. In the redox flow battery, the electrode total surface area is 40,000 cm2 or greater and the attachment rate is 1% or greater, the attachment rate being a value obtained by placing in a horizontal state a predetermined size sample collected from an arbitrary location in the layered electrode, dripping a predetermined amount of pure water from above the sample, erecting vertically the sample whereon the pure water has been dripped, measuring the mass of this sample, removing from this measurement value the mass of the sample prior to dripping, and dividing this quantity by the mass of the pure water.
