Abstract
The present disclosure relates to an electrode having improved safety and a secondary battery including the same. It is possible to prevent or significantly reduce an internal short-circuit between a positive electrode current collector and a negative electrode current collector and an internal short-circuit between a positive electrode current collector and a negative electrode active material layer, caused by nail penetration, by controlling the elongation of a positive electrode to 0.6-1.5%.
