Current Li-ion batteries offer good ionic conductivity but have safety issues due to the flammability of their electrolytes. Two of the ways to improve the capabilities of Li-ion batteries is to improve safety or use Li-metal anode, which may require solid electrolytes. In this work, solid polymer electrolytes (SPEs) are prepared by crosslinking poly(ethylene glycol) diacrylate with poly(ethylene glycol) methyl ether acrylate to form an interpenetrating network with poly(propylene carbonate) using LiClO4 as salt. The prepared SPEs were characterized using FTIR spectroscopy to determine ion interactions between polymers and LiClO4. The glass-transition temperatures, mechanical stabilities, and electrochemical properties of the SPEs were determined in terms of PPC and LiClO4 content. SPEs showed two glass-transition temperatures corresponding to an XLPEO+LiClO4 phase and PPC+LiClO4 phase and no crystallization/melting. The Young's modulus of the SPEs at 5 wt% LiClO4 increased from 3 MPa at 5 wt% PPC to 37 MPa at 20 wt% PPC. The toughness and tensile strength of the SPEs also showed significant improvement upon the addition of PPC. The ionic conductivity of the SPEs decreased with increasing PPC or LiClO4 content and the ion transport mechanisms were examined through the Arrhenius, Vogel-Tammann-Fulcher (VTF), and Maxwell equations. The SPEs do not follow the Arrhenius model which confirms that ion transport is not via the hopping mechanism. Additionally, the SPEs support the Maxwell model confirming that there is ion conduction in the two phases observed from the thermal analysis.","**To request an accessible version of the file(s) associated with this item, contact library@buffalo.edu.
