Provided is a polyurethane gel composition containing A and B below. Here, A represents a polyurethane obtained by reaction of (a) a hydrogenated polybutadiene having isocyanate groups at the terminals and (b) a glycol represented by HO—R.sub.3—OH (wherein R.sub.3 represents a linear or branched C2 to C6 alkylene group optionally having an ether bond), or A represents a polyurethane obtained by reaction of (c) a hydrogenated polybutadiene having hydroxyl groups at the terminals, (d) a diisocyanate compound, and the (b) glycol represented by HO—R.sub.3—OH (wherein R.sub.3 represents a linear or branched C2 to C6 alkylene group optionally having an ether bond), and B represents an oil agent. The polyurethane gel composition of the present invention is particularly useful as a raw material for cosmetics since a film of an oil-soluble gel obtained using the polyurethane gel composition is exceptionally excellent in any point of transparency, high gloss, elasticity, and resilience.

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.
