Abstract
This work obtained gel polymer electrolytes (GPEs) via in situ polymerization of methyl methacrylate (MMA) in the environment of lithium bis(trifluoromethane sulfonyl)imide (LiTFSI) and N-methyl-N-propylpyrrolidinium bis(trifluoromethane sulfonyl)amide (Py13TFSI). The thermogravimetric analysis (TGA) and the differential scanning calorimeter (DSC) determined the non-isothermal decomposition of Py13TFSI/LiTFSI/PMMA polymer electrolyte for Li-ion battery. TGA, DSC, and the infrared graph analyzed thermodynamic properties, and the results showed the addition of Py13TFSI significantly improved the thermostability of electrolytes. Flynn-Wall-Ozawa (Ozawa), Kissinger-Akahira-Sunose (KAS), and Friedman methods applied for kinetics characteristics to activation energy (Ea) and pre-exponential factor (A). The Ea value from Ozawa and KAS methods was 208.478 kJ mol−1 and 207.423 kJ mol−1, respectively.
