General solid polymer electrolytes (SPEs) for lithium-ion batteries have good advantages, such as flexibility and less flammability. However, SPEs have lower ionic conductivities than conventional liquid electrolytes. In our work, we prepared poly(lithium acrylate) (PLA)-based composite polymer electrolytes (CPEs) using inorganic nanoparticles and cellulose fillers acting as the cross-linkers and reinforcing agents, respectively. The combination of the inorganic nanoparticles and cellulose fillers can synergistically increase the ionic conductivity as well as the mechanical properties of CPE. We systematically investigated the effect of filler content on ionic conductivity and mechanical properties of PLA-based CPE using DSC, XRD, FE-SEM, FTIR, rheometer, and EIS. These CPEs containing inorganic nanoparticles and cellulose fillers can provide prospective and efficient insights into the design of energy storage devices such as lithium-ion batteries and supercapacitors. |
