Abstract
Official abstract text for this publication.
The purpose of the present invention is to provide an electrode which is used as a liquid flow-through device electrode and in which liquid flow-through resistance is reduced and the utilization efficiency of carbon fiber is enhanced. Another object of the present invention is to provide a redox flow battery having excellent charge-discharge performance by use of the electrode which is used for the liquid flow-through device. The present invention provides an electrode for a liquid flow-through device, the electrode essentially consisting of a carbon fiber nonwoven fabric, having a thickness of more than 0.40 mm, and having a through-hole disposed therein, or a non-through-hole disposed on one surface or both surfaces of the electrode.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrode, the electrode essentially consisting of a carbon fiber nonwoven fabric, having a thickness of more than 0.4 mm, and having a non-through-hole having a depth of more than 400 μm disposed on one surface or both surfaces of the electrode. 2. A redox flow battery comprising a cell form using the electrode according to claim 1 . 3. The electrode according to claim 1 , which has a thickness of more than 0.60 mm. 4. The redox flow battery according to claim 2 , wherein the redox flow battery is a flow-through type redox flow battery. 5. The redox flow battery according to claim 2 , wherein the redox flow battery is a flow-by type redox flow battery. 6. The redox flow battery according to claim 2 , wherein a non-through-hole having a depth of more than 400 μm is disposed on both surfaces of the electrode. 7. The redox flow battery according to claim 2 , wherein broken fiber is not observed in a peripheral edge portion of the non-through-hole in plan view. 8. The electrode according to claim 1 , wherein broken fiber is not observed in a peripheral edge portion of the non-through-hole in plan view. 9. The redox flow battery according to claim 2 , wherein an opening diameter of the non-through-hole is 50 μm to 10 mm. 10. The electrode according to claim 1 , wherein an opening diameter of the non-through-hole is 50 μm to 10 mm. 11. The redox flow battery according to claim 2 , wherein an area ratio (opening area/total area) of the non-through-hole is 5 to 50% in plan view. 12. The electrode according to claim 1 , wherein an area ratio (opening area/total area) of the non-through-hole is 5 to 50% in plan view.
