| description | To provide an electrode for a nonaqueous electrolyte secondary battery, which has a large weight and a high adhesion and which achieves excellent input and output characteristics and high durability.SOLUTION: An electrode for a nonaqueous secondary battery comprises: a current collector; and an electrode active material layer on the current collector, which contains an active material containing carbon particles capable of occluding and desorbing at least a lithium ion, and a binder. The binder contains a polymer compound having a weight-average molecular weight of 50-2000000 and having an acidic functional group and a polyvinylidene fluoride skeleton as a main chain. The content of the binder in the electrode active material layer is 2-8 mass%.SELECTED DRAWING: None
【課題】高目付で高い密着性を有し、優れた入出力特性及び高耐久性を与える非水系電解質二次電池用電極を提供する。【解決手段】集電体上に、少なくともリチウムイオンを吸蔵・脱離可能な炭素粒子を含む活物質と、バインダーとを含有する電極活物質層を備えた電極において、前記バインダーが、酸性官能基と主鎖としてポリフッ化ビニリデン骨格とを有する重量平均分子量５０〜２００万の高分子化合物を含み、かつ、電極活物質層中のバインダーの含有率が２〜８質量％であることを特徴とする、非水系二次電池用電極。【選択図】なし |
