Secondary battery electrode additive

Abstract

Provided is a secondary battery electrode additive with which an active material can be coated without heat treatment that is performed at a high temperature for a long period of time, an alkaline component can be neutralized, and the decomposition of an electrolytic solution can be suppressed. For example, provided is a secondary battery electrode additive comprising a boronic acid derivative represented by formula (5). (In the formula, R1-R5 each independently represent a hydrogen atom, an alkyl group, an ester group, a glycol chain, an alkoxy group, or a hydroxy group, and R6 represents a hydrogen atom, a methyl group, or an ethyl group.)

Dependencies are inferred from the claim text.
