Polymeric binder has turned out to be very critical for stable operation of high capacity battery electrodes including silicon (Si) anodes, as the binder could stabilize the electrode films even during the large volume change of active materials. In this talk, I will present novel binder designs focusing on supramolecular chemistries targeting high capacity battery materials represented by silicon. Such binder designs include 1) the use of mussel-inspired catechol functional group, 2) multi-dimensional cross-linkable hydrogen bonding network, 3) self-healing polymer network, 4) host-guest interaction network, and finally 5) elastic binder network incorporating molecular machines. The series of these investigations suggest the usefulness of noncovalent polymer interactions and the future role of supramolecular chemistry in the binder development.
