Ion-selective membranes are key components for sustainable energy devices, including osmotic power generators, electrolyzers, fuel cells, and batteries. These membranes facilitate the flow of desired ions (permeability) while efficiently blocking unwanted ions (selectivity), which forms the basis for energy conversion and storage technologies. To improve the performance of energy devices, the pursuit of high-quality membranes has garnered substantial interest, which has led to the exploration of numerous candidates, such as polymeric membranes (e.g., polyamide and polyelectrolyte), laminar membranes (e.g., transition metal carbide (MXene) and graphene oxide (GO)) and nanoporous 2D membranes (e.g., single-layer MoS₂ and porous graphene). Despite impressive progress, the trade-off effect between ion permeability and selectivity remains a major scientific and technological challenge for these membranes, impeding the efficiency and stability of the resulting energy devices.

用于可持续能源设备的二维聚合物膜的水面合成

离子选择性膜是可持续能源设备的关键组件，包括渗透发电机、电解槽、燃料电池和蓄电池。这些膜促进所需离子的流动（渗透性），同时有效阻挡不需要的离子（选择性），这构成了能量转换和存储技术的基础。为了提高能源设备的性能，对高质量膜的追求引起了人们的极大兴趣，这导致了对众多候选膜的探索，例如聚合物膜（例如聚酰胺和聚电解质）、层状膜（例如过渡金属碳化物）（MXene）和氧化石墨烯（GO））和纳米多孔2D膜（例如，单层MoS ₂和多孔石墨烯）。尽管取得了令人印象深刻的进展，但离子渗透性和选择性之间的权衡效应仍然是这些膜的主要科学和技术挑战，阻碍了由此产生的能源设备的效率和稳定性。
