Beschreibung
Zusammenfassung:	To provide polymer binders for silicon or silicon-graphite composite electrodes, and the use thereof in electrochemical cells.SOLUTION: Described are polymers, polymer binders, hydrogel polymer binders, hydrogel polymer binder compositions comprising them, electrode materials comprising them, methods of producing them, and the use thereof in electrochemical cells, e.g., in silicon-based electrochemical cells. The hydrogel binders may be mainly formed through the H-bonding between a water-soluble polymeric binder and a polyphenol, which may act as strong interaction or physical cross-linking points, thereby forming a 3D complex.SELECTED DRAWING: None 【課題】ケイ素またはケイ素－グラファイト複合材電極のためのポリマー結合剤、および電気化学セルにおけるそれらの使用を提供すること。【解決手段】ポリマー、ポリマー結合剤、ヒドロゲルポリマー結合剤、これらを含むヒドロゲルポリマー結合剤組成物、これらを含む電極材料、それらの生成法および電気化学セル、例えば、ケイ素ベースの電気化学セルにおけるそれらの使用が記載される。上記ヒドロゲル結合剤は、強い相互作用または物理的架橋点として働き得、それによって、３Ｄ複合体を形成する、水溶性ポリマー結合剤とポリフェノールとの間のＨ結合を通じて主に形成され得る。【選択図】なし
