Transition‐metal sulfides have been regarded as perspective anode candidates for high‐energy Na‐ion batteries. Their application, however, is precluded severely by either low charge storage or huge volumetric change along with sluggish reaction kinetics. Herein, an effective synergetic Sn incorporation‐Zn substitution strategy is proposed based on copper‐based sulfides. First, Na‐ion storage capability...
Magnesium‐ion batteries (MIBs) are emerging as potential next‐generation energy storage systems due to high security and high theoretical energy density. Nevertheless, the development of MIBs is limited by the lack of cathode materials with high specific capacity and cyclic stability. Currently, transition metal sulfides are considered as a promising class of cathode materials for advanced MIBs. Herein,...
Polycrystalline perovskite films fabricated on flexible and textured substrates often are highly defective, leading to poor performance of perovskite devices. Finding substrate‐tolerant perovskite fabrication strategies is therefore paramount. Herein, this study shows that adding a small amount of Cadmium Acetate (CdAc2) in the PbI2 precursor solution results in nano‐hole array films and improves...
