Two Binding post/studs are through Soft Roll poly-bag, and the upper end open end of described Soft Roll poly-bag arranges one block of viscose glue, and viscose glue seals the opening of Soft Roll poly-bag, and one piece of upper hush panel is placed at the top of viscose glue；
Two Binding post/studs, through viscose glue and the upper end of the supreme hush panel of upper hush panel, two Binding post/studs stretched out are set with a nut, and nut engages with Binding post/stud, and upper hush panel is compressed by the lower end of nut with viscose glue.
As preferred technical scheme, form an irregular gap between described Soft Roll poly-bag, viscose glue and soft-package battery, fill up in this irregular gap and fill fire-resistant fluid.
As preferred technical scheme, the middle, upper end of described soft-package battery arranges a waterproof vent valve, and waterproof vent valve is through lower sealing plate, viscose glue and the upper surface of the supreme hush panel of upper hush panel.
As preferred technical scheme, described viscose glue uses elastic silica gel material to make.
The beneficial effects of the utility model are: 1) simple, and realizability is high；
2) function is realized by the physicochemical characteristics of PACK, it is not necessary to extra complication system；
3) present invention is by isolation air and two mechanism of dilute electrolyte, and then reaches the purpose of " preventing " fire.
