Novel solid polymer electrolytes based on succinonitrile (SN) plastic crystal electrolyte (SN-PCE) and polymerized ionic liquid (PIL) has been successfully synthesized via an in-situ method. The fabricated electrolyte (PIL-SN-PCE) is uniformly inlayed into the supporting matrix of polyimide, which effectively ameliorates the mechanical properties of the electrolyte. PIL can effectively enhance the thermal stability of electrolytes up to 300 °C and mitigate the parasitic reactions between the electrolytes and the electrodes. PIL-SN-PCE exhibits a remarkable oxidation ability up to 5.4 V vs Li/Li+ and a high room temperature ionic conductivity of 6.54 × 10-4 S cm-1. Furthermore, in-situ formed interface in PIL-SN-PCE guarantee an excellent compatibility with different electrodes, which can effectively improve the cycle stability and rate performances of both half-cells and full cells. Finally, PIL-SN-PCE is considered as a promising electrolyte for high energy density lithium-ion batteries.
