Ionic liquid N-methyl-N-propyl-pyrrolidinium bis(fluorosulfonyl)imide (Pyr.sub.13FSI) was introduced into a hybrid network to obtain a series of gel polymer electrolytes (GPEs). Mechanical and electrochemical properties of the GPEs were tuned through controlling the network structure and ionic liquid contents, and ionic conductivity higher than 1 mS cm.sup.?1 at room temperature was achieved. The newly developed GPEs are flame-retardant and show excellent thermal and electrochemical stability as well as ultra-stability with lithium metal anode. Symmetrical lithium cells with the GPEs exhibit a stable cycling over 6800 h at a current density of 0.1 mA cm.sup.?2 and stable lithium stripping-plating at 1 mA cm.sup.?2, the highest current density reported for ionic liquid-based GPEs. Moreover, Li/LiFePO.sub.4 batteries with the obtained GPEs exhibit desirable cycling stability and rate performance over a wide temperature range from 0? C. to 90? C.
