HIGHLY ELASTIC PHYSICALLY CORSS-LINKED BINDER INDUCED BY REVERSIBLE ACID-BASE INTERACTION FOR HIGH PERFORMANCE SILICON ANODE

摘要

The present invention relates to a polymer binder for a silicon negative electrode, physically cross-linked with a cross-linking agent through reversible acid-base interaction and, more specifically, to a polymer binder for a silicon negative electrode, physically cross-linked with a cross-linking agent through reversible acid-base interaction, having excellent strength and elasticity. Accordingly, the polymer binder for a silicon negative electrode, physically cross-linked with a cross-linking agent through reversible acid-base interaction comprises: a binder for a silicon negative electrode; and a cross-linking agent physically coupled to the binder for a silicon negative electrode through the reversible acid-base interaction.
