Summary:To reduce the internal resistance of a non-aqueous electrolyte secondary battery compared to before.SOLUTION: A battery binder includes a copolymer represented by the following general formula (1). (In the formula, R1 is a component represented by the general formula (2). R2 is a component represented by either general formula (3) or (4). R3 is a component containing at least a thiocarbonylthio group, and R4 is a component containing at least one of a nitrile group, an aromatic ring and a carbonyl group.)SELECTED DRAWING: Figure 2 【課題】非水電解質二次電池の内部抵抗を従来よりも低減する。【解決手段】以下の一般式（化１）によって表される共重合体を含む電池用バインダーとした。【化１】TIFF2023064584000037.tif10168（式中、Ｒ１は一般式（化２）によって表される構成要素である。Ｒ２は一般式（化３）及び（化４）のいずれかによって表される構成要素である。Ｒ３は少なくともチオカルボニルチオ基を含む構成要素である。Ｒ４はニトリル基、芳香環及びカルボニル基のうち少なくとも１つを含む構成要素である。）【選択図】図２
