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).
1 . An electrode to be used 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. 2 . The electrode according to claim 1 , which is used for a redox flow battery. 3 . The electrode according to claim 1 , wherein a non-through-hole having a depth of more than 400 μm is disposed on one surface or both surfaces of the electrode. 4 . The electrode according to claim 1 , wherein broken fiber is not observed in a peripheral edge portion of the through-hole or the non-through-hole in plan view. 5 . The electrode according to claim 1 , wherein an opening diameter of the through-hole or the non-through-hole is 50 μm to 10 mm. 6 . The electrode according to claim 1 , wherein an area ratio (opening area/total area) of the through-hole or the non-through-hole is 5 to 50% in plan view. 7 . The electrode according to claim 1 , which has a thickness of more than 0.60 mm. 8 . The electrode according to claim 2 , which is used for a flow-through type redox flow battery. 9 . The electrode according to claim 2 , which is used for a flow-by type redox flow battery. 10 . A redox flow battery comprising a cell formed using the electrode according to claim 2 . 11 . A redox flow battery comprising a flow-through type cell formed using the electrode according to claim 8 . 12 . A redox flow battery comprising a flow-by type cell formed using the electrode according to claim 9 . 13 . The electrode according to claim 2 , wherein a non-through-hole having a depth of more than 400 μm is disposed on one surface or both surfaces of the electrode. 14 . The electrode according to claim 2 , wherein broken fiber is not observed in a peripheral edge portion of the through-hole or the non-through-hole in plan view. 15 . The electrode according to claim 3 , wherein broken fiber is not observed in a peripheral edge portion of the through-hole or the non-through-hole in plan view. 16 . The electrode according to claim 2 , wherein an opening diameter of the through-hole or the non-through-hole is 50 μm to 10 mm. 17 . The electrode according to claim 3 , wherein an opening diameter of the through-hole or the non-through-hole is 50 μm to 10 mm. 18 . The electrode according to claim 4 , wherein an opening diameter of the through-hole or the non-through-hole is 50 μm to 10 mm. 19 . The electrode according to claim 2 , wherein an area ratio (opening area/total area) of the through-hole or the non-through-hole is 5 to 50% in plan view. 20 . The electrode according to claim 3 , wherein an area ratio (opening area/total area) of the through-hole or the non-through-hole is 5 to 50% in plan view.
