摘要

The electrode treatment agent for alkali metal secondary batteries which can improve the lifetime of a battery by suppressing precipitation of a dendrite is provided. The following general formula (1) (Wherein, X is a hydrogen atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, and a CFX 1 X 2 group (provided that X 1 and X 2 are the same or different and are a hydrogen atom, a fluorine atom, or a chlorine atom) ), a cyano group, a linear or branched fluoroalkyl group having 1 to 21 carbon atoms, a substituted or unsubstituted benzyl group, a substituted or unsubstituted phenyl group, or a linear or branched alkyl group having 1 to 20 carbon atoms, Y is a hydrocarbon group having 1 to 10 carbon atoms which may have a direct bond, an oxygen atom or a sulfur atom, -CH 2 CH 2 N (R 1) SO 2 - group (where R 1 is an alkyl group having 1 to 4 carbon atoms. ), -CH 2 CH(OY 1 )CH 2 -group (provided that Y 1 is a hydrogen atom or an acetyl group), or -(CH 2 ) n SO 2 -group (n is 1 to 10), and Rf is It is a linear or branched alkyl group having 2 to 7 carbon atoms and a fluorinated alkyl group. Alkali metal electrode treatment agent.
