Asymmetrically-channeled two-dimensional membrane for stable, selective lithium-ion transport

Key Points

• To develop a stable and selective membrane for lithium-ion transport using an asymmetric-channel design.
• Proposed an asymmetric-channel concept for membrane design
• Fabricated a GO-TiO2 membrane
• Evaluated selectivity for Li+/Mg2+ ions
• Achieved high selectivity for lithium ions over magnesium ions
• Demonstrated stable ion transport performance
• Enhanced efficiency for various separation applications
