| description | To provide an electrode binder that exhibits excellent cycle characteristics when used in an electricity storage device.SOLUTION: In the elastic term E' and the viscous term E" in which a film (thickness: 1.0 to 2.0 mm) obtained by swelling an electrode binder in a solvent used for the electrolyte are measured under conditions of an indentation of 1 μm, a measurement temperature of 25°C, and a frequency of 1 Hz using a dynamic viscoelasticity measuring device, the requirements of either (1) Elastic term E' is ≥4.5×106(Pa) or (2) Viscosity term E" is ≥0.9×106(Pa) are satisfied.SELECTED DRAWING: None
【課題】本発明は、蓄電デバイスに用いた際には、サイクル特性に優れる、電極用バインダーを提供することを目的とする。【解決手段】電極用バインダーを電解液に用いられる溶媒に膨潤させ得られるフィルム（厚み１．０～２．０ｍｍ）を、動的粘弾性測定装置を用いて、押込み量１μｍ、測定温度２５℃、周波数１Ｈｚの条件で測定される弾性項Ｅ'と粘性項Ｅ"において、（１）弾性項Ｅ'が≧４．５×１０６（Ｐａ）（２）粘性項Ｅ"が≧０．９×１０６（Ｐａ）（１）、（２）のいずれかの要件を満たす電極用バインダーであることが課題を解決することを見出した。【選択図】なし |
