Beschreibung
Zusammenfassung:	To provide a binder for an electrochemical device capable of improving life characteristics of the electrochemical device by following a volume change of an electrode structure due to discharge and charge.SOLUTION: The binder for an electrochemical device is a binder for a secondary battery containing a polymer having at least one cyclic host group in a molecule. The host group exists as a side chain of the polymer. A main chain of the polymer penetrates at least a part of the cyclic host group.SELECTED DRAWING: None 【課題】放充電に伴う電極構造の体積変化に追従し、電気化学デバイスの寿命特性を改善することができる電気化学デバイス用結着剤を提供する。【解決手段】分子中に少なくとも１の環状のホスト基を有する高分子を含有する二次電池用結着剤であって、前記ホスト基は、高分子の側鎖として存在するものであり、少なくとも一部の環状のホスト基中を、前記高分子の主鎖が貫通していることを特徴とする電気化学デバイス用結着剤。【選択図】なし
