表面改性纳米SiO2复合聚合物电解质的制备及性能
Preparation and Characterization of Composite Polymer Electrolytes Containing Surface-modified Nano Silica
摘要
Abstract
Nano silica with carbonate groups were synthesized by the esterification reaction and ihe structure of the modified nano silica were characterized by FTIR and TGA methods. The composite polymer electrolytes (CPEs) were prepared by introducing the modified nano silica. The thermal and electrochemical performances of the CPEs were studied by DSC and AC impedance. The results show that the addition of modified nano silica enhance the thermal properties and ionic conductivities of CPEs, and meanwhile the lithium ion transference number of CPEs increase up to 0. 49. AC impedance results reveal that modified nano silica can also improve the interfacial stability between CPEs and lithium metal electrode.关键词
