Patent ID: 7902299

Claim:
A method of making a single-ion conductor comprising: grafting a salt compound on to a polymer containing double bonds, wherein the polymer comprises a comb-branch polymer, wherein the comb-branch polymer has the following structure: wherein R 4 comprises —(CH 2 CH 2 O)—, —(CH 2 CH 2 CH 2 O)—, —(CH 2 CH 2 CH 2 CH 2 O)—, —(CH 2 CHR 5 O)—, where R 5 is CH 3 —, CH 3 O— or CH 3 OCH 2 CH 2 O—, where R 6 is —CH 2 , O, or NH, n is an integer from about 2 to about 20, and x and y are chosen such that the ratio x/y is from 1 to 30.
