Abstract
An electrode for a flow battery and a method for producing the electrode enable the electrode to be placed in contact with an electrolytic solution of the flow battery. The electrode includes a first portion consisting of particles of electrically conductive material having nanometric dimensions. The first portion is mesoporous with a porosity that increases the quantity of redox reactions per time unit in a flow of the electrolytic solution of the battery.
Claims18
An electrode for a flow battery, comprising:
- a first portion that can be placed in contact with an electrolytic solution of said battery (B), wherein said first portion is mesoporous and consists of particles of electrically conductive material having nanometric dimensions;
- and
- a second portion that supports said first portion and includes a plurality of carbon filaments, wherein said first portion coats, at least partly, at least one of said filaments with a layer of said particles,
- wherein the layer of said particles has a thickness that varies along a depth and/or a length of said electrode, and/or the first portion has a porosity that varies along a depth and/or a length of said electrode.
