Evaluation of triphenylene-based MOF ultrathin films for lithium batteries.

Metal-organic frameworks (MOFs) are attractive candidates to meet the requirement of next-generation batteries, as functional materials with a high surface area, well-defined metal centers, and organic linkers through coordination bonds. Due to their great tunability, MOFs have been investigated as electrodes or electrolytes in lithium batteries and more recently as protective layers in anode-less batteries. Here, we synthesize a Ni(HHTP) MOF directly at the air-liquid interface of a Langmuir trough and grow the electrode on a conductive substrate by the transference process.
