Rechargeable battery

A rechargeable battery that minimizes a current amount difference between a double-sided coated region and a single-sided coated region by increasing resistance of the single-sided coated region to be higher than that of the double-sided coated region in an electrode plate (e.g., a negative electrod...

Beschreibung
Zusammenfassung:	A rechargeable battery that minimizes a current amount difference between a double-sided coated region and a single-sided coated region by increasing resistance of the single-sided coated region to be higher than that of the double-sided coated region in an electrode plate (e.g., a negative electrode plate). A rechargeable battery including: an electrode assembly including an electrode plate at opposite sides of a separator and spirally winding the separator and the electrode plates; and a pouch to accommodate the electrode assembly therein and to draw out an electrode tab connected to the electrode plates to the outside thereof. The electrode plate includes: a double-sided coated region having an active material on opposite sides of a substrate and a single-sided coated region having an active material on a single surface of the substrate, wherein resistance of the single-sided coated region is higher than that of the double-sided coated region.
