Abstract
A secondary battery includes a first electrode plate, a second electrode plate and a separator. The first electrode plate has a plurality of first active material coating portions formed by intermittently coating a first active material on a base material, and a first non-coating portion at which the first active material is not coated on the base material. The second electrode plate has a second active material coating portion formed by coating a second active material on a base material, and a second non-coating portion at which the second active material is not coated on the base material. The separator is interposed between the first and second electrode plates.

A secondary battery, comprising:
- a first electrode plate having a plurality of first active material coating portions formed by intermittently coating a first active material on a base material, and a first non-coating portion at which the first active material is not coated on the base material;
- a second electrode plate having a second active material coating portion formed by coating a second active material on a base material, and a second non-coating portion at which the second active material is not coated on the base material;
- and
- a separator interposed between the first and second electrode plates,
- wherein the first non-coating portion includes a first internal non-coating portion provided between the first active material coating portions adjacent to each other,
- wherein a first electrode tab and an insulating member provided to cover the first electrode tab are provided to the first internal non-coating portion,
- wherein the first electrode tab is protruded outward from the first internal non-coating portion so as to face a first direction, and the insulating member is provided to have an area wider than that of the first internal non-coating portion,
- wherein the insulating member is protruded outward from the first internal non-coating portion by a first length in the first direction, and is protruded outward from the first internal non-coating portion by a second length in a second direction opposite to the first direction, and
- wherein the first length is formed longer than the second length.
