Synoptical membrane structure with multiple energy storage

What are 2D membranes based on?

In this review, we concentrate on the recent progress of 2D membrane and introduce 2D membranes based on graphene oxide (GO), MXenes, 2D MOFs, 2D COFs, and 2D zeolite nanosheets, which are applied in membrane separation (H2 collection and biofuel purification) and battery separators (vanadium flow battery, Li–S battery, and fuel cell).

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.

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.

What is a smart polycage membrane?

A Smart Polycage Membrane with Responsive Osmotic Energy Conversion Based on Synchronously Switchable Microporosity and Chargeability Membranes with specific pore sizes are widely used in molecular separation, ion transport, and energy conversion.

Are nanofluidic membranes good for osmotic energy conversion?

Provided by the Springer Nature SharedIt content-sharing initiative Nanofluidic membranes offer exceptional promise for osmotic energy conversion, but the challenge of balancing ionic selectivity and permeability persists.

Can 2D MOF membranes be used for osmotic energy conversion?

Leveraging both the in-plane pores and interlayer transport pathways, these 2D MOF membranes have demonstrated considerable promise in gas and molecular separation 18, 19, 20, 21. However, the utilization of 2D MOF membrane in osmotic energy conversion applications remains notably scarce.
