Highly elastic physically cross-linked binder induced by reversible acid-base interaction for high performance silicon anode

摘要

Provided is a highly elastic physically cross-linked binder induced by reversible acid-base interaction for high performance silicon anode, and more particularly to a highly elastic physically cross-linked binder induced by reversible acid-base interaction for high performance silicon anode, in which the binder has excellent stiffness and elasticity. To this end, the polymer binder that is physically crosslinked with a crosslinking agent by acid-base interaction may include a crosslinking agent that is physically bound with the binder for silicon anode by reversible acid-base interaction with the binder for silicon anode.
