Vacancy‐Suppressed Garnet Electrolytes for Durable Solid‐State Batteries
Advanced Science, EarlyView.A Li/O‐rich sintering strategy effectively suppresses intrinsic lithium and oxygen vacancies in cubic garnet electrolytes, yielding a dense and stable microstructure. The vacancy‐controlled electrolyte exhibits enhanced interfacial and air stability, enabling long‐term solid‐state battery cycling and providing a general design principle for defect ...

Self‐Healing Starch‐Based Ionogels with Hydroneutral Dipole–Dipole Interactions
Advanced Science, EarlyView.This work introduces starch‐based, conductive, underwater‐healable, and transparent ionogels for soft electronics (SCUTEs). Starch macromolecules are partially substituted with cyanoethyl groups and incorporated with hydrophobic ionic liquid. The polar yet hydroneutral cyanoethyl groups facilitate strong dynamic dipole–dipole interactions that remain ...
