Secondary battery including retainer for electrode assembly

摘要

A secondary battery includes an electrode assembly includes first and second electrode non-coating portions exposed from respective sides of an electrode assembly, first and second collecting plates in contact with and fixed to the respective first and second electrode non-coating portions, a retainer including first and second fixing slits that accommodate the first and second collecting plates connected to the electrode assembly, respectively, and a case that accommodates the retainer accommodating the electrode assembly and the first collecting plate. The retainer includes a first side part including the first fixing slit, a second side part facing the first side part and including the second fixing slit, and a bottom part connecting the first and second side parts to each other.

主权项

1. A secondary battery, comprising:
an electrode assembly including a first electrode plate including a first electrode non-coating portion, a second electrode plate including a second electrode non-coating portion, and a separator disposed between the first and second electrode plates, the first electrode non-coating portion and the second electrode non-coating portion being exposed from sides of the electrode assembly, respectively; a first collecting plate and a second collecting plate that are in contact with and fixed to the first electrode non-coating portion and the second electrode non-coating portion, respectively; a retainer including a first fixing slit and a second fixing slit that accommodate the first and second collecting plates connected to the electrode assembly, respectively, the retainer having a first side part that includes the first fixing slit, having a second side part that faces the first side part and includes the second fixing slit, and having a bottom part that connects the first and second side parts to each other; a case that accommodates the retainer accommodating the electrode assembly and the first collecting plate, the case having an upper opening; and a cap plate closing the upper opening of the case accommodating the electrode assembly, the first and second collecting plates, and the retainer.
