Preparation of cation exchange membrane as a separator for the all-vanadium redox flow battery

Polymer electrolyte based on chemically stable and highly conductive alkali-doped polyoxadiazole for direct borohydride fuel cell

“…The area resistance of membranes was measured following the method in the previous report [8]: a conductivity cell was separated into two compartments filled with 3 M NaOH solution. The effective area of the cell (S) was 1 cm 2 .…”

Development of Pore-filled Ion-exchange Membranes for Efficient All Vanadium Redox Flow Batteries

“…Especially, redox flow battery (RFB) is known as one of very promising largescale energy storage batteries. [1][2][3] The main feature of this system is the use of active electrode materials dissolved in a solution, and therefore it can offer several advantages such as very fast electrode reaction, unlimited system design for high power and capacity, instant and fast recharging by replacing the spent electrolytes and so on. [1][2][3] There are a variety of redox couples which can be used in flow batteries, and, for example, all-vanadium redox flow battery (VRB), which is the most widely used, is a type of rechargeable flow battery that employs vanadium ions in different oxidation states as the active electrode materials.…”
