Abstract

Polymeric gel electrolytes (GPE) based on PMMA and PVDF-HFP were prepared using the binary mixtures of γ-butyrolactone (GBL) and ethylene carbonate (EC) as plasticizers. The ionic transport properties and electrochemical stability were studied. The room temperature conductivity reached 1.2 mS·cm~(-1), electrochemical stability window exceeded 4.5V. The interfacial stability between GPE and lithium electrode was also investigated. The lithium metal polymer battery (LMPB) prepared with the GPE showed better charge and discharge life cycle when the the lithium metal electrode was treated with 1,4-dioxane.
