Advanced Materials, EarlyView.This study explores iodine substitution in solid electrolytes to overcome sluggish redox kinetics and poor charge transport in all‐solid‐state Li‐S batteries. The resulting iodine‐rich, amorphous phase and superionic, nanocrystalline domains enable effective redox mediation and provide a robust ionic percolation network.

Advanced Materials, EarlyView.This work unveils the multifunctional roles of Prussian blue analogs (PBAs) within the LPSCl matrix, where they act as effective moisture scavengers and enable partial recovery of electrochemical performance. In addition, owing to their relatively soft nature, PBAs help mitigate interfacial stress and thereby enhance electrochemical stability and ...

A Solid State Zwitterionic Plastic Crystal With High Static Dielectric Constant
Advanced Materials, EarlyView.Developing solid high dielectric constant materials has been a research focus in the energy storage field. In this research, we discovered a zwitterion with a plastic crystal phase. Due to the short‐range degree of freedom of the dipole moment for this zwitterion, a relatively high static dielectric constant has been achieved in its solid state ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes
Advanced Materials, EarlyView.Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of
