摘要： A battery can include an electrode assembly having a first electrode, a second electrode and a separator. The first electrode can include a first active material region coated with an active material layer along a winding direction and a first uncoated region not coated with the active material layer, and at least part of the first uncoated region used as an electrode tab. The battery can further include a first current collector coupled to at least part of the first uncoated region on the electrode assembly, a battery housing to accommodate the electrode assembly and the first current collector, and an insulator between an inner surface of the battery housing facing the first uncoated region or the first current collector and the first uncoated region or the first current collector to block the electrical connection between the first uncoated region and the battery housing.

摘要： A separator for an electrochemical device. The separator includes a porous coating layer formed from an acid, which is crosslinkable. As a result, the separator has increased heat resistance, safety and physical strength, shows improved peel strength between the porous substrate and the porous coating layer, and prevents separation of the inorganic particles from the porous coating layer. In addition, the separator shows an improved crosslinking degree so that the added amount of a crosslinkable binder resin may be reduced. Thus, it is possible to increase the added amount of a non-crosslinkable resin, inorganic particles, or both. Even when using a small amount of a crosslinkable binder resin, it is possible to provide both an effect of improving heat resistance and an effect of improving adhesion.
