摘要：
A lithium secondary battery includes: a first electrode having a first current collector, and first active material patterns formed on the first current collector such that the first active material patterns are symmetrically disposed with a first center non-coated portion formed therebetween; a second electrode having a second current collector, and second active material patterns formed on the second current collector such that the second active material patterns are symmetrically disposed with a second center non-coated portion formed therebetween; a first electrode tab connected to the first center non-coated portion; and a second electrode tab connected to the second center non-coated portion.
