Abstract

The accelerated lifetime test device for a redox flow battery according to the present invention includes a test cell including a separator configured to exchange ions contained in an electrolyte, first and second manifolds disposed on both side surfaces of the separator and having openings through which the electrolyte flows, a cathode disposed on an outer side surface of the first manifold, an anode disposed on an outer side surface of the second manifold, and first and second end plates respectively disposed on outer side surfaces of the cathode and the anode, a rotator configured to uniformly disperse the electrolyte included in the test cell by rotating the test cell and a tester connected to each of the cathode and the anode of the test cell and configured to test performance of the test cell.

First claim

What is claimed is:

1 . An accelerated lifetime test device for a redox flow battery, the test device comprising:
a test cell including a separator configured to exchange ions contained in an electrolyte, first and second manifolds disposed on both side surfaces of the separator and having openings through which the electrolyte flows, a cathode disposed on an outer side surface of the first manifold, an anode disposed on an outer side surface of the second manifold, and first and second end plates respectively disposed on outer side surfaces of the cathode and the anode; a rotator configured to uniformly disperse the electrolyte included in the test cell by rotating the test cell; and a tester connected to each of the cathode and the anode of the test cell and configured to test performance of the test cell.

2 . The test device claim 1 , wherein:
an active material of the cathode includes zinc ions; and an active material of the anode includes bromine ions.

3 . The test device claim 1 , wherein the rotator includes:
a rotating unit configured to uniformly disperse the electrolyte included in the test cell by rotating the test cell; a driving unit configured to drive the rotating unit; and a manipulating unit configured to control an operation of the driving unit.

4 . The test device claim 3 , wherein the rotating unit rotates the test cell at a speed of 1 to 10,000 rpm within a range from −180 to +180 degrees.

5 . The test device claim 4 , wherein the rotating unit rotatably moves the test cell 10 left or right at a predetermined angle.

6 . The test device claim 5 , wherein the rotating unit includes:
a supporter; a rotating shaft rotatably coupled to the supporter and rotated by the driving unit; and an accommodation unit fixedly coupled to the rotating shaft and configured to accommodate the test cell.
