Abstract

In this paper, ZrO₂ is deposited on a polyethylene-based separator via electron beam evaporation method. The analyses reveal that the application of the ceramic-based coating enhances the electrolyte uptake capability from 79 to 135% and the ionic conductivity from 7.1 × 10⁻⁴ to 7.5 × 10⁻⁴ S/cm. Linear sweep voltammetry tests show the superior electrochemical stability in the coated separator up to 5.5 V. This study shows that with the thin ZrO₂ coating, the separator maintains its structure plus the existence of ZrO₂ has an essential impact on electrolyte decomposition, SEI layer formation, and safety of the separator.
