Title:

REDOX FLOW BATTERY ELECTRODE, REDOX FLOW BATTERY CELL, AND REDOX FLOW BATTERY SYSTEM

Document Type and Number:

WIPO Patent Application WO/2024/075439

Kind Code:

A1

Abstract:

This redox flow battery electrode comprises a fiber assembly including carbon fibers, wherein the carbon fibers each include: a plurality of groove portions that are provided along the length of the carbon fiber; a ridge portion that is between the groove portions and relatively protrudes beyond the groove portions; and a cross-section in which the perimeter of the carbon fiber is larger than the perimeter of a virtual circle. The cross-section is a section made by cutting the carbon fiber by a plane orthogonal to the length of the carbon fiber. The virtual circle is a true circle having an area equal to the area of the cross-section.
