Secondary cell with improved electrode jelly-roll structure |
摘要 |
A secondary cell capable of ensuring thermal and mechanical stabilities required for a high-capacity cell with a simple structure is provided. The secondary cell includes: a can; and an electrode jelly-roll wound with two different electrodes and a separator interposed between the electrodes therein and accommodated in the can, the outer surface of the electrode jelly-roll being wound around one more turn with the separator. Only the separator is wound at the core of the electrode jelly-roll to form a rod-like stability member which is cured by absorbing heat generated from the cell. The separator wound at the core of the electrode jelly-roll is continuous from a portion of the separator which is stacked with the two different electrodes.
