A secondary battery includes: a main body accommodating an electrode assembly; a sealing part formed along an outer periphery of the main body and including an upwardly bent part; and a circuit board connected to an electrode lead extending outward from the main body and arranged between the main body and the bent part of the sealing part. The secondary battery is suitable for providing a compact structure.

Secondary battery

A secondary battery including a pouch having recessed portions inwardly recessed at at least one of opposite sides of the pouch, an electrode assembly including first electrode plates, second electrode plates and separators, the separators being disposed between the first electrode plates and second electrode plates, the electrode assembly being inside the pouch, and a lead tab coupled to the electrode assembly and exposed to the outside of the pouch. The separators protrude from the first electrode plates or the second electrode plates by different protruding lengths at different regions corresponding to the recessed portions of the pouch in a thickness direction of the electrode assembly.

Secondary battery and fabricating method thereof

A secondary battery includes: an electrode assembly; a case accommodating the electrode assembly; an electrode tab extending from the electrode assembly; a sealing part for insulating the electrode tab from the case; and an insulation film around the electrode tab and between the sealing part and the electrode assembly.
