Abstract:
A negative electrode for a secondary battery, the negative electrode including: a current collector; an interlayer on the current collector and consisting of at least one first polymer selected from a cation-substituted polycarboxylic acid and a copolymer thereof; a negative electrode active material layer on the interlayer and which includes a negative electrode active material and a binder.
Abstract:
An electrode assembly includes an electrode stack structure including a first electrode assembly sheet having flexibility and a second electrode assembly sheet having flexibility, where and the first and second electrode assemblies are alternately disposed one on another, and a binding unit which binds a portion of the electrode stack structure. The first electrode assembly sheet includes first and second separator films disposed to face each other, a first electrode sheet which is disposed between the first and second separator films and includes a first electrode collector and a first active material layer, and a first confining unit which restricts a movement of the first electrode sheet with respect to the first and second separator films.
