▎ 摘　　要

NOVELTY - The method (10) for preparing carbon felt electrode with flow channel, involves providing (11) carving platform, and establishing a coordinate system in the space above the engraving platform. The porous fiber felt is fixed (12) on the carving platform. The engraving head is moved and rotated (13) in the coordinate system according to the preset speed and preset route. The flow channels are engraved on the surface of the porous fiber mat to obtain the carved porous fiber mat. The conductive solution is coated (14) in the flow channels of the sculpted porous fiber mat. The carved porous fiber mat is carbonized (15) to finally obtain a carbon felt electrode with flow channels after the solvent of the conductive solution is volatilized. USE - Method for preparing carbon felt electrode with flow channel used in liquid flow battery energy storage system. ADVANTAGE - The method is safe and reliable to prepare the electrode under the precondition of ensuring the conductivity. The problems of concentration polarization of flow batteries and poor conductivity of electrodes with flow channels are effectively solved, and the overall performance of batteries is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation system of carbon felt electrode.
