Synergistic Effects of Solid Electrolyte Mild Sintering and Lithium Surface Passivation for Enhanced Lithium Metal Cycling in All‐Solid‐State Batteries

open access: yesAdvanced Science, EarlyView.
This study proposes a synergistic strategy combining mild sintering of solid electrolyte pellets with lithium metal surface passivation, effectively suppressing dendrite growth, and enhancing interfacial stability. This approach doubles the critical current density of symmetric cells (1.1 to 2.2 mA cm−2) and extends full cells cycle life at 1 mA cm−2 ...

A Functionality‐Graded Cathode Electrolyte Interphase Enables Ultra‐Long Cycling Stability in Aqueous Zn–Mn Batteries

open access: yesAdvanced Science, EarlyView.
Through the interfacial reaction of KH2PO4, a functionally graded CEI with hydrated, organic, and inorganic layers is constructed. This suppresses interfacial water corrosion, mitigates volume stress, and promotes charge carrier transport, achieving superior battery stability.

Ultra‐Thin Hybrid Ion Exchange Interlayer for High Performance Aqueous Zn Metal Batteries

open access: yesAdvanced Science, EarlyView.
An ultra‐thin SPEEK/FCD ion‐exchange interlayer modulates the Zn2+ solvation environment (–SO3−), provides ion‐exchange pathways that homoginized the Zn2+ flux, and via F‐rich chemistry forms in situ ZnF2 that suppresses parasitics and stabilizes the interface; its integrity relieves interfacial stress.
