As lithium ion sources of a single ion conductor, core–shell structured SiO2(Li+) nanoparticles with uniform spherical shape are synthesized and used as functional fillers in composite polymer electrolytes. As reported on page 1019 by Woo Young Yoon, Dong-Won Kim, and co-workers, the composite polymer electrolytes prepared with SiO2(Li+) particles exhibit high ionic conductivity and good mechanical strength and are used to prepare thin films for high performance lithium powder polymer batteries.
