A secondary battery is disclosed. In one embodiment, the secondary battery includes i) a first electrode plate having two opposing surfaces, wherein the first electrode plate comprises a first electrode collector and a first electrode coating portion disposed on at least one of the two surfaces of the first electrode collector and ii) a second electrode plate having two opposing surfaces, wherein the second electrode plate comprises a second electrode collector and a second electrode coating portion disposed on at least one of the two surfaces of the second electrode collector. The secondary battery may further include a separator disposed between the first and second electrode plates and electrically insulating the first and second electrode plates from each other. The first electrode plate may further include a first electrode tab that extends from a first side surface of the first electrode collector, wherein the first side surface connects the two opposing surfaces of the first electrode collector, and wherein the first electrode coating portion extends to an extension region of the first electrode tab. The second electrode plate may further include a second electrode tab that extends from a second side surface of the second electrode collector, where in the second side surface connects the two opposing surfaces of the second electrode collector, and wherein the second electrode coating portion extends to an extension region of the second electrode tab.
