Long-Range Uniform Deposition of Ag Nanoseed on Cu Current Collector for High-Performance Lithium Metal Batteries.

Uniform lithium deposition is essential to hinder dendritic growth. Achieving this demands even seed material distribution across the electrode, posing challenges in correlating the electrode's surface structure with the uniformity of seed material distribution. In this study, the effect of periodic surface and facet orientation on seed distribution is investigated using a model system consisting of a wrinkled copper (Cu)/graphene structure with a [100] facet orientation.

Synergistic Effect of Cu O Mesh Pattern on High-Facet Cu Surface for Selective CO Electroreduction to Ethanol.

Although the electroconversion of carbon dioxide (CO ) into ethanol is considered to be one of the most promising ways of using CO , the ethanol selectivity is less than 50% because of difficulties in designing an optimal catalyst that arise from the complicated pathways for the electroreduction of CO to ethanol. Several approaches including the fabrication of oxide-derived structures, atomic surface control, and the Cu /Cu interfaces have been primarily used to produce ethanol from CO . Here, a combined structure with Cu and high-facets as electrocatalysts is constructed by creating high-facets of wrinkled Cu surrounded by Cu O mesh patterns.
