摘要: The rational design of improved electrode-electrolyte interfaces (EEI) for energy storage is critically dependent on a molecular-level understanding ionic interactions and nanoscale phenomena. presence non-redox active species at EEI has been shown to strongly influence Faradaic efficiency long-term operational stability during processes. Herein, we achieve substantially higher performance prepared with highly dispersed discrete redox-active cluster anions (50 ng pure ∼0.75 nm size molybdenum polyoxometalate (POM) 25 μg (∼0.2 wt%) carbon nanotube (CNT) electrodes) by complete elimination coordinating through ion soft landing (SL). Electron microscopy provides atomically resolved images uniform distribution individual POM landed directly complex technologically relevant CNT electrodes. In this context, SL established as versatile approach the controlled novel surfaces both fundamental applied research in storage.
