Abstract
Four sides of a rectangular bag-like separator 10 are composed of two adjacent separator thermo-bonding sides 10a and 10c where thermo-bonding portions are formed and of two adjacent insertion opening sides 10b and 10d forming one insertion opening 11 into which an electrode 30 can be inserted. A thermo-bonding section is formed in a portion of at least one of the insertion opening sides 10b and 10d.
Claims7
A rectangular bag-like separator produced in the form of a bag by thermo-bonding of peripheral portions of a resin film, wherein the rectangular bag-like separator defines four separator sides including two adjacent first and second bonding sides each including a bonding section therein, and two adjacent first and second insertion opening sides defining an insertion opening through which an electrode is allowed to be inserted,
- wherein said first insertion opening side has a bonding section therein, and said first insertion opening side is adjacent to said first bonding side, and
- wherein said second bonding side has first and second bonding sections spaced from each other therein.
