Composition for electrode formation and additive

Abstract

The present invention provides, as a composition for electrode formation having improved storage stability and higher solid content concentration, while suppressing thickening and gelation by a simple method, a composition for electrode formation, the composition containing a stabilization component, a positive electrode active material, a binder and a solvent, wherein the stabilization component contains: (first component) a heterocycle-containing compound which has a reactive group and a nitrogen-containing five-membered ring without containing an oxygen atom in the nitrogen-containing five-membered ring, and (second component) a compound which is chemically reactive with the heterocycle-containing compound; the first component, the second component, and a reaction product that is obtained by having the first component and the second component react with each other; or the reaction product that is obtained by having the first component and the second component react with each other.
