Abstract

Composite polymer electrolytes (CPE) based on triethylene glycol diacetate-2-propenoic acid butyl ester (TEGDA-BA) incorporating Al₂O₃ nanoparticles have been fabricated via in situ polymerization. The CPE have exhibited highly uniform morphology, excellent mechanical property (maximum stress up to ~1.3MPa), high ionic conductivity up to 3.92×10^-3Scm^-1 at 25°C, coupled with very high electrochemical stability (>5.0V vs. Li/Li⁺). The Li^|CPE|Li[Li_1/6Ni_1/4Mn_7/12]O_7/4F_1/4 cells have demonstrated remarkably stable charge/discharge performance and great capacity retention in the potential range of 2.0-4.8V. The unexpected growth of interface resistance has been retarded with the presence of Al₂O₃, indicating the enhancement of the interface stability. The results suggest that the CPE have demonstrated tremendous application potential in high-voltage lithium ion batteries.
