Abstract
We demonstrate a facile approach to improve the cycling stability of spinel LiNi0.5Mn1.5O4 materials by their surface modification. The cross-linked composite polymer electrolyte layer was formed on the surface of LiNi0.5Mn1.5O4 by radical polymerization between diethylene glycol diacrylate and SiO2 nanoparticles with reactive vinyl groups. The protective composite polymer layer formed on the LiNi0.5Mn1.5O4 materials suppressed the irreversible decomposition of the electrolyte at high voltages and reduced the dissolution of transition metals from the charged LiNi0.5Mn1.5O4 electrode into the electrolyte at elevated temperature, which resulted in more stable cycling characteristics than the pristine LiNi0.5Mn1.5O4 electrode.
