Patent ID: 8765309

Claim:
An electrochemical device comprising a pair of electrodes and provided therebetween, a gelled nonaqueous electrolyte composition containing an electrolyte and a gelling agent having two or more amide groups in the chemical structure, wherein the gelling agent is a compound represented by formula (A), (B) or (C): wherein plural R 1 s independently represent a straight chained alkoxy group having a carbon atom number of from 1 to 12 a substituted or unsubstituted alkyl group having a carbon atom number of from 1 to 18, an aralkyl group having a carbon atom number of from 7 to 21 or a substituted or unsubstituted aryl group having a carbon atom number of from 6 to 20; and R 2 represents an amino acid derivative segment represented by the following formula (D), wherein n1 represents an integer of from 1 to 15, and plural R 5 s independently represent a substituted or unsubstituted alkyl group having a carbon atom number of from 1 to 22; R 3 and R 4 represent the same as those denoted above in any of R 1 s and R 2 ; x1 represents an integer of from 0 to 500; and y1 represents an integer of from 0 to 400, provided that when y1 is 0, at least one of R 3 and R 4 represents the amino acid derivative segment represented by formula (D) above, wherein plural R 6 s independently represent a substituted or unsubstituted alkyl group having a carbon atom number of from 1 to 22; x2 represents an integer of from 1 to 500; and n2 represents an integer of from 1 to 15, wherein plural R 7 s independently represent a straight chained alkoxy group having a carbon atom number of from 1 to 22 a substituted or unsubstituted alkyl group having a carbon atom number of from 1 to 18, an aralkyl group having a carbon atom number of from 7 to 21 or a substituted or unsubstituted aryl group having a carbon atom number of from 6 to 20; and x3 represents an integer of from 0 to 500.
