제목 Highly Stable Composite Separator for Lithium Ion Battery via Electron Beam Irradiation Technology
초록 Interfaces between organic and inorganic are important to maximize the synergy of hybridization. Polyethylene separator coated with inorganic film is a presentative technology for manufacturing a variety of secondary batteries with high safety. Unfortunately, organic/inorganic hybrid separators have the disadvantage of non-ideal interfaces, so they have poor thermal/dimensional stability. Here, we report a simple way to solve the shortcomings of the non-ideal interface between polyethylene separators and SiO2 deposited to produce highly stable separators through the strong chemical connection (Si-O-C or Si-CH3) by direct electron beam irradiation. Simple treatment with dose-optimized electron beams can create thermally stable polymer separators to improve battery safety at high temperatures, with enhanced ion transport between the cathode and the anode inducing better charge/discharge behavior.
