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.

Solar Energy Storage Using a Cu O-TiO Photocathode in a Lithium Battery.

A Cu O-TiO photoelectrode is pr+oposed for simultaneous solar light energy harvesting and storing of electrochemical energy in an adapted lithium coin cell. The p-type Cu O semiconductor layer is the light harvester component of the photoelectrode and the TiO film performs as the capacitive layer. The rationale of the energy scheme shows that the photocharges generated in the Cu O semiconductor induce lithiation/delithiation processes in the TiO film as a function of the applied bias voltage and light power.
