Composite gel polymer electrolytes containing core-shell structured SiO _2(Li ~+) particles for lithium-ion polymer batteries

摘要

In this work, we report novel composite gel polymer electrolyte for lithium-ion polymer batteries. As the lithium ion sources of single ion conductor, the core-shell structured SiO _2(Li ~+) particles with uniform spherical shape are synthesized and used as functional fillers in composite gel polymer electrolytes. We show that our material, based on the incorporation of core-shell structured SiO _2(Li ~+) particles into a gel polymer matrix, acts as a very effective polymer electrolyte for lithium-ion polymer batteries.
