Pole plate group 3 is that be wound as swirling by up-coiler, then outermost adhesive tape is tamping, thus forms circinate pole plate group by the diaphragm clip that is made up of micro-porous films such as polyethylene between positive plate and negative plate.This pole plate group 3 is inserted in battery container 1.One end of negative wire is connected with negative plate, and the other end is connected with the bottom of battery container 1, and one end of positive wire 11 is connected with positive plate, and the other end is connected with the base plate 91 of the hush panel 9 of battery.After inject nonaqueous electrolytic solution in battery container 1, the opening of battery container 1 is sealed by hush panel 9 and liner 10.
As shown in Figure 1, forming hollow space at the central part of circinate pole plate group 3, in order to prevent hollow space from deforming in battery charge and discharge process, and guaranteeing gas outlet channels, among the hollow space that the central part of swirling pole plate group 3 is formed, insert and configure the stem stem 8 of hollow.
Here, stem stem 8 not necessarily, that is, also can not at the central part configuration stem stem 8 of swirling pole plate group 3.
Referring to Fig. 2, Fig. 3, insulation board 4 of the present utility model is described in detail.
Insulation board 4 is in the form of annular discs, covers the upper surface of pole plate group 3.Insulation board 3 is formed with through hole 5 and center covering part 6 etc.
