Abstract
An object of the present invention is to provide an electrode which is used for a liquid flow-through device and in which liquid flow-through resistance is reduced and the utilization efficiency of the surface 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 to be used for a liquid flow-through device, the electrode including a plurality of sheets of carbon fiber nonwoven fabric each having irregularities on a surface of the sheet of carbon fiber nonwoven fabric being stacked or each having a through-hole on the carbon fiber sheet being stacked, and having inside of the electrode a plurality of gaps which is formed by recesses of the irregularities or the through-hole and is not opened in a thickness direction.
