Abstract
(EN)
The present invention provides an electrode forming material which is easy to increase the content ratio of an active material, while being easily prepared, and which is not likely to cause problems of odor or stability. An electrode forming material according to the present invention is composed of at least one active material (A) and a viscous electrolyte composition; the viscous electrolyte composition contains at least one ionic substance (S) and an organic composition (P-O) that contains at least one polymer (P) and a low molecular weight organic compound (O) having a molecular weight of less than 10,000; the content ratio of the polymer (P) in the organic composition (P-O) is 50% by mass or less; and the ratio of the compounds having a volatilization ratio that is not less than the volatilization ratio of N-methyl pyrrolidone in the low molecular weight organic compound (O) is from 0% by mass to 20% by mass (inclusive).
