Overview

Experimental study demonstrates durable pilot-scale mixed-matrix membranes in flow batteries and water electrolyzers, highlighting viable pathways for industrial energy storage.

Key Points

To develop scalable, alkaline-stable porous membranes for commercial-scale energy storage and conversion cell stacks.
Fabricated porous poly(ether sulfone) (PES)/ZrO2 mixed-matrix membranes at a pilot scale.
Evaluated chemical stability in a 30 wt % KOH solution at 80 °C over 500 hours.
Tested performance in alkaline zinc-iron flow battery single cells, 500 W-scale cell stacks, and lab-scale zero-gap alkaline water electrolyzer stacks.
The membrane exhibited 0.218% mass degradation after 500 h of exposure to 30 wt % KOH at 80 °C.
Membranes maintained stable and efficient operation across 500 W-scale alkaline zinc-iron flow battery stacks and alkaline water electrolyzer stacks.
