What are ion-conductive membranes used for?

Membranes with fast and selective ion transport are widely used for water purification and devices for energy conversion and storage including fuel cells, redox flow batteries and electrochemical reactors. However, it remains challenging to design cost-effective, easily processed ion-conductive membranes with well-defined pore architectures.

Can low-cost hydrocarbon membranes be used for grid energy storage?

This work illustrates a potential pathway for manufacturing and upscaling of next-generation cost-effective flow batteries based on low-cost hydrocarbon membranes developed in the past decades to translate to large-scale applications for grid energy storage.

Why do we need a membrane for energy storage & conversion?

The current energy crisis has prompted the development of new energy sources and energy storage/conversion devices. Membranes, as the key component, not only provide enormous separation potential for energy purification but also guarantee stable and high-efficiency operation for rechargeable batteries and fuel cells.

Can hydrocarbon membranes be used in terawatt-scale flow batteries?

Future terawatt-scale deployment of flow batteries will require substantial capital cost reduction, particularly low-cost electrolytes and hydrocarbon ion exchange membranes. However, integration of hydrocarbon membranes with novel flow battery chemistries in commercial-scale stacks is yet to be demonstrated.

How efficient is the Speek membrane?

To further demonstrate the performance of the SPEEK membrane, we scaled up the flow battery cell stacks ranging from 300 to 4,000 W with membrane areas scaled up from 4,375 cm 2 to 3 m 2, and the energy efficiency of the stack remained nearly unchanged (Figure 5 B).

Are 2D material separation membranes a good choice for energy field applications?

Remarkably, two-dimensional (2D) material separation membranes have attracted intense attention on their excellent performance in energy field applications, owing to high mechanical/chemical stability, low mass transport resistance, strict size-exclusion, and abundant modifiable functional groups.
