| 摘要 |
The present invention relates to an electrode assembly (10, 50, 60) comprising a first electrode (11, 51, 61), a second electrode (12, 52, 62), and a separator (13, 53, 63) disposed between the first electrode (11, 51, 61) and the second electrode (12, 52, 62), wherein a side portion (13a, 53a, 63a) of the separator (13, 53, 63) extends farther to the first side of the electrode assembly (10, 50, 60) along a first axis than a side portion of an uncoated region (12c, 52b, 62b) of the second electrode (12, 52, 62) at a temperature range of 20° to 60° C, wherein the first axis extends parallel to the main surfaces of the electrodes (11, 51, 61, 12, 52, 62) and perpendicular to edges of the electrodes (11, 51, 61, 12, 52, 62) located at the first side of the electrode assembly (10, 50, 60). |
