Abstract:
The present disclosure relates to porous electrodes, membrane-electrode assemblies, electrode assemblies and electrochemical cells and liquid flow batteries produced therefrom. The disclosure further provides methods of making porous electrodes, membrane-electrode assemblies and electrode assemblies. The porous electrodes include a porous electrode material comprising a non-electrically conductive, polymer particulate; and an electrically conductive carbon particulate; wherein the electrically conductive carbon particulate is at least one of carbon nanotubes and branched carbon nanotubes. The electrically conductive carbon particulate is adhered directly to the surface of the non-electrically conductive, polymer particulate and at least a portion of the non-electrically conductive polymer particulate surface is fused to form a unitary, porous electrode material.
Abstract:
The present disclosure relates to porous electrodes and electrochemical cells and liquid flow batteries produced therefrom. The disclosure further provides methods of making electrodes. The porous electrodes include polymer, e.g. non-electrically conductive polymer particulate fiber, and an electrically conductive carbon particulate. The non-electrically conductive, polymer particulate fibers may be in the form of a first porous substrate, wherein the first porous substrate is at least one of a woven or nonwoven paper, felt, mat and cloth. The porous electrode may have an electrical resistivity of less than about 100000 μOhm·m. The porous electrode may have a thickness from about 10 microns to about 1000 microns. Electrochemical cells and liquid flow batteries may be produced from the porous electrodes of the present disclosure.
