As a promising low‐cost and high‐safety energy storage candidate, zinc‐ion hybrid capacitors (ZIHCs) have received extensive attention. For maximizing the advantages of ZIHC with high energy density and high power density, the structural engineering of the porous carbon materials is the crucial and effective strategy. Herein, an oxygen‐enriched hierarchical porous carbon has been fabricated from the...
The construction of conductive scaffolds is demonstrated to be an ideal strategy to alleviate the volume expansion and dendrite growth of K metal anodes. Nevertheless, the heterogeneous top–bottom deposition behavior caused by incompatible electronic/ionic conductivity of three‐dimensional (3D) skeleton severely hinders its application. Here, a K2Se/Cu conducting layer is fabricated on the Cu foam...
As a favorable candidate for the next‐generation anode materials, metallic lithium is faced with two crucial problems: uncontrollable lithium plating/stripping process and huge volume expansion during cycling. Herein, a 3D lithiophilic skeleton modified with nanoscale Bi sheets (Ni@Bi Foam, i.e., NBF) through one‐step facile substitution reaction is constructed. Benefiting from the nanoscale modification,...
All‐Inorganic perovskite CsPbX3 (X = Cl, Br, I) quantum dots (QDs) have attracted tremendous attention in the past few years for their appealing performance in optoelectronic applications. Major properties of CsPbX3 QDs include the positive photoconductivity (PPC) and the defect tolerance of the in‐band trap states. Here it is reported that when hybridizing CsPbX3 QDs with indium tin oxide (ITO) nanocrystals...
