Published: March 3, 2025

Compositing inorganic ceramics and polymer materials to form all-solid-state electrolytes has been recognized as a feasible approach for the development of batteries. However, polymer-based such polyethylene oxide can electrochemically decompose above 3.9 V (vs . Li+/Li), which results in undesirable battery performance. Moreover, dendrite growth occur on anode side further lead short-circuit. This work designs successfully fabricates stable electrode/electrolyte interfaces both composite cathode sides after employing alucone coating layers made through atomic layer deposition. Due protection capability layers, electrochemical degradation between solid-state Li7La3Zr2O12/polyethylene oxide/lithium bis(trifluoromethane-sulfonyl) imide film nickel-rich high voltage (LiNi0.8Mn0.1Co0.1O2) obviously suppressed significantly improved anti-oxidation electrolyte. Simultaneously, function protective barrier lithium metal anode, remarkably suppressing dendrites. As result, obtained batteries with dual show capacity retention long cycle life, whereas contrasting without shows fast decay micro-shorting behavior. presents an effective strategy constructing more polymers-based batteries, also provides design rationale structure field energy storage conversion.
