Energy storage battery membrane equipment manufacturing

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.

What are the advantages of a battery membrane?

The membranes significantly surpass the limit performance of most of existing membrane materials, which enables efficient and highly stable battery performances and long-duration storage up to 14 h.

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.

Can sulfonated poly (ether ether ketone) membranes be used in flow batteries?

Here, we report the pilot-scale synthesis and roll-to-roll manufacturing of sulfonated poly (ether ether ketone) (SPEEK) membranes and demonstrate their high hydroxide conductivity and chemical stability in kW-scale alkaline-based flow batteries.

Can a hydrocarbon ion exchange membrane upscale a next-generation alkaline-based flow battery?

In summary, we have demonstrated the upscaling of next-generation alkaline-based flow batteries using a low-cost hydrocarbon ion exchange membrane with excellent alkaline stability and achieved superior performance from lab-scale to kW-scale stacks.

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).
