Patent ID: 7771891

Claim:
An ionic conductor comprising at least a polymer of carbon clusters having the formula (1): where R 1 includes a hydrocarbon group or a derivative thereof; A 1 and A 2 is selected from the group consisting of an element including any one of nitrogen, phosphorus, oxygen, and sulfur, and functional groups containing one or more of the elements wherein at least one of A 1 and A 2 are contained in the polymer; Q includes a residue of carbon cluster; R 2 includes a hydrocarbon group or a derivative thereof; Z y− q M x+ p includes an ion-dissociating group where x, y, p, and q are natural numbers such that px=qy; M x+ includes a cation with a valence value of x; m represents the number of the ion-dissociating groups introduced into each of the carbon cluster residues; and n represents the degree of polymerization, wherein the carbon cluster polymer includes at least one functional group selected from the group consisting of bis-sulfonylimide group (—SO 2 —NH—SO 2 —), bis-sulfonylmethylene group (—SO 2 —CH 2 —SO 2 —), biscarbonylimide group (—CO—NH—CO—), and sulfonylcarbonyl-imide group (—CO—NH—SO 2 —).
