Flexible batteries can be easily adapted from emerging novel wearable electronics to electrical vehicles and advanced solar panels. Solid-state batteries can greatly reduce the risk of fire or leaking hazardous materials due to puncture. For the development of solid-state flexible lithium based batteries polymer-ceramic composites are attractive electrolyte candidates because of their combined properties, such as electrical, thermal and mechanical properties, that not only overcome limitations from the base materials but may also render some enhanced performances resulting from the interaction among the components. In this study polymer-ceramic composite electrolytes consisting of polyethylene oxide (PEO), Li1.4Al0.4Ge1.6(PO4)3 (LAGP) and two lithium salts (LiTFSI and LiBF4) are studied. Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC), and Dynamic Mechanical Analysis (DMA) are used to characterize their thermal and mechanical characteristics. The glass transition temperature, onset of melting, the decomposition temperature, the characteristics of the stiffness and strength as a function of temperature are determined and analyzed. It is aimed to determine how the lithium salts and LAGP ceramic impact the thermal and mechanical properties of the electrolytes. 2020 English text Wright State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=wright1609971094548742 http://rave.ohiolink.edu/etdc/view?acc_num=wright1609971094548742 unrestricted This thesis or dissertation is protected by copyright: some rights reserved.
