Gelation of sulfolane-based highly concentrated electrolytes using a partially fluorinated polymer enhances the Li-ion transference number of the electrolytes because acidic protons surrounded by fluorine atoms in the polymer network trap anions, and the high Li+ transference number is effective in suppressing the concentration polarization in Li batteries.

We demonstrate that tetra-arm poly(ethylene glycol) gels containing highly concentrated sulfolane-based electrolytes exhibit high Li+ transference numbers. The low polymer concentration and homogeneous polymer network in the gel electrolyte are useful in achieving both mechanical reliability and high Li+ transport ability.
