Abstract
As a method for improving the service life of a Li-ion battery, a supramolecular structure of acrylic acid which is a polymer formed by aggregating m number (an aggregation degree of m) of single chains each including n number (a polymerization degree of n) of acrylic acid monomers connected to each other, and has a constricted (narrowing) channel structure in which the single chains are arranged in a circle on the xy plane, a main chain is oriented along the direction of a central axis in the z direction, and a carboxyl group in a side chain is oriented along a direction perpendicular to the central axis in the z direction is used. As a result of an interaction between this constricted channel structure and an organic solvent molecule, the organic solvent molecule is captured inside the constricted channel structure, and the diffusion of the organic solvent molecule is inhibited.
