Abstract
Compositing inorganic ceramics and polymer materials to form all-solid-state electrolytes has been recognized as
a feasible approach for the development of all-solid-state batteries. However, polymer-based electrolytes such as
+
polyethylene oxide can electrochemically decompose above 3.9 V (vs. Li /Li), which results in undesirable battery
performance. Moreover, dendrite growth can occur on the anode side and further lead to battery short-circuit. This
work designs and successfully fabricates stable electrode/electrolyte interfaces on both the composite cathode
and anode sides after employing alucone coating layers made through atomic layer deposition. Due to the
protection capability of such coating layers, the electrochemical degradation between the composite solid-state
