Polymer binders for silicon or silicon-graphite composite electrodes, and their use in electrochemical cells

摘要

Described are polymers, polymer binders, hydrogel polymer binders, hydrogel polymer binder compositions containing them, electrode materials containing them, their production methods and their use in electrochemical cells such as silicon-based electrochemical cells. Will be done. The hydrogel binder can act as a strong interaction or physical cross-linking point, whereby it can be formed primarily through the H-bond between the water-soluble polymer binder and the polyphenol, which forms a 3D complex.
