A unique interfacial conversion concept is proposed to establish robust cathode electrolyte interphase for stabilizing fluorinated polyanionic cathodes in aqueous electrolytes. In a typical case, the conformal Al2O3 sacrificial layer is predeposited on high‐voltage sodium vanadium oxy‐fluorophosphates cathode, which can progressively react with trace ...

Nano‐Oil‐Barrier‐Based Fluttering Triboelectric Nanogenerator
This work proposes a wind‐driven nano‐oil‐barrier‐based fluttering triboelectric nanogenerator (NF‐TENG). A nano‐oil barrier is a simple and innovative strategy to maintain a thin lubricant layer for long‐term cycling based on commercial oil‐absorbing sheets and oil‐infusion steps, which can improve both mechanical and electrical stability of TENGs ...

A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...
