Abstract
An electrode assembly according to the present disclosure includes an electrode stack part formed by stacking at least one radical unit having a four-layered structure of a first electrode, a separator, a second electrode and a separator, and an electrode fixing part for wrapping and fixing the electrode stack part. The electrode assembly according to the present disclosure may be fabricated by means of a stacking process other than a folding process, and may accomplish accurate alignment and stable fixing.
Claims13
An electrode assembly comprising:
- an electrode stack part obtained by stacking at least one radical unit including a four-layered structure of a first electrode, a first separator, a second electrode, and a second separator;
- and an electrode fixing part for wrapping and fixing the electrode stack part,
- wherein the radical unit is formed by attaching the electrodes and the separators to each other,
- wherein each of the electrodes includes an electrode current collector and an electrode active material coated on the electrode current collector,
- wherein a first surface of the first separator is coated with a coating material having adhesiveness to allow the coating material of the first surface of the first separator to be adhered to the electrode active material of the first electrode,
- wherein the coating material is a mixture of inorganic particles and a binder polymer, and
- wherein a second surface of the first separator is uncoated with the coating material having adhesiveness to permit direct pressurization onto the second surface.
