    • An object of the present invention is to provide a binder resin composition which exhibits excellent adhesion to the negative electrode current collector and an excellent resistance to liquid electrolyte-induced swelling, and which provides an electrode having excellent flexibility and plasticity. Additional objects of the present invention are to provide, through the use of this binder resin composition, an electrode for nonaqueous electrolyte energy devices and a nonaqueous electrolyte energy device, which exhibit a high capacity as well as a smaller capacity fading during charge-discharge cycling. A binder resin composition for a nonaqueous electrolyte energy device electrode comprises a copolymer that contains a repeat unit derived from a nitrile group-containing monomer; a repeat unit derived from a monomer represented by Formula (I) (wherein R1 is H or CH3; R2 is H or monovalent hydrocarbonyl group; and n is an integer from 1 to 50) and/or a repeat unit derived from a monomer represented by Formula (II) (wherein R3 is H or CH3 and R4 is hydrogen or C4-100 alkyl); and optionally a repeat unit derived from a carboxyl group-containing monomer.
    • 本发明的目的是提供一种粘合剂树脂组合物,其对负极集电体具有优异的粘附性,并且具有优异的耐液体电解质溶胀性,并且提供了具有优异的柔韧性和可塑性的电极。 本发明的另外的目的是通过使用这种粘合剂树脂组合物,提供非水电解质能装置用电极和非水电解质能装置,其在充放电循环中表现出高容量以及较小的容量衰减 。 非水电解质能装置用电极用粘合剂树脂组合物含有含有含腈基单体的重复单元的共聚物, 衍生自由式(I)表示的单体(其中R 1是H或CH 3)的单体的重复单元; R 2是H或单价 烃基; n为1至50的整数)和/或衍生自由式(II)表示的单体(其中R 3为H或CH 3)的重复单元, 并且R 4是氢或C 4〜C 1-4烷基); 和任选的衍生自含羧基单体的重复单元。
