| 摘要 |
An electrode assembly and a lithium secondary battery with the electrode assembly improve reliability and stability of the lithium secondary battery by protecting the lithium secondary battery from external impact applied thereto when a user drops the lithium secondary battery onto the ground. The electrode assembly includes a first electrode plate, a second electrode plate, and a separator interposed between the first and second electrodes so as to insulate the first electrode plate from the second electrode plate. A protruding width of an upper section of the separator, which protrudes upward from the first and second electrodes, is greater than a protruding width of a lower section of the separator, which protrudes downward from the first and second electrodes.
