Document Type and Number:
WIPO Patent Application WO/2018/181772
Kind Code:
A1
Abstract:
The main purpose of the present invention is to provide a binder for electrodes, which has excellent flexibility and binding properties, and which enables an electricity storage device such as a lithium ion secondary battery and an electrochemical capacitor to have a lower internal resistance at an SOC of 50%. Another purpose of the present invention is to provide: an electrode which is obtained using this electrode binder; and an electricity storage device which is provided with this electrode. A binder for electrodes, which contains a polymer (A) that has a constituent unit derived from a (meth)acrylic acid ester and a constituent unit derived from a polyfunctional (meth)acrylate and a non-crosslinked polymer (B) that has a constituent unit derived from an alkoxyalkyl (meth)acrylate and a constituent unit derived from a (meth)acrylic acid; an electrode which is obtained using this binder for electrodes; and an electricity storage device which is provided with this electrode.
