Abstract
The utility model relates to a structure of a cylindrical secondary battery, relating to the structures of secondary batteries. The structure of the cylindrical secondary battery comprises a battery shell (1), a pole piece (2) arranged inside the inside space of the battery shell, and a pole cap (5) which is arranged at the outer end of the battery shell (1), wherein the battery shell (1) is straight-barrel-shaped. According to the utility model, the sealing structure of a ni-mh cylindrical secondary battery is fundamentally changed, thus the effective space inside the battery shell is improved by 5%.
Description
Technical field
The utility model relates to the structure of column secondary battery.
Background technology
The present method for packing of the general column secondary battery of ni-mh is with the battery case slot rolling, then is added with the top cover of insulated ring above slot rolling, bends at last the method sealed cell at battery case edge, slot rolling top by sealing, sees Fig. 3.The method makes the required battery space that takies the part in battery case of existing sealed cell body large, thus reduced battery pole piece the space of battery case internal capacity large not, affect the capacity of battery, be unfavorable for the production of high-capacity battery.
Summary of the invention
The purpose of this utility model is to provide the structure of the column secondary battery that increases the inner useful space of battery case under a kind of prerequisite not changing cell integrated apparent size.
The purpose of this utility model can realize like this, the structure of a kind of column secondary battery of design, comprise battery container, be arranged on the battery container inner space pole piece, be arranged on the polar cap of battery container outer end, battery container is straight tubbiness.
Further, battery container is straight tubbiness, and port arranges welding cap, by being welded and fixed sealing.
Further, battery container comprises two straight stavings, and two straight staving port docking are by being welded and fixed sealing.
The utility model has fundamentally changed the sealing process of ni-mh column secondary battery, and the inner useful space of the battery case of new technology encapsulation can improve 5% left and right.
Description of drawings
Fig. 1 is the schematic diagram of one of the utility model preferred embodiment;
Fig. 2 is two schematic diagram of the utility model preferred embodiment;
Fig. 3 is traditional cylindrical battery appearance schematic diagram.
Embodiment
The utility model will be further described below in conjunction with embodiment.
As shown in Figure 1 and Figure 2, a kind of structure of secondary cell, comprise battery container 1, be arranged on the battery container inner space pole piece 2, be arranged on barrier film 3 between pole piece 2, be separately positioned on two ends, battery container inner space insulation cushion 4, be arranged on the polar cap 5 of battery container outer end, fixedly polar cap 5 securing member 6 of being connected with sealing ring, the lug 8 that connects securing member 6 and battery pole piece one utmost point, battery container 1 is straight tubbiness.
In the present embodiment, securing member 6 is rivet.
The sealing means of battery container 1 has multiple.The utility model adopts welding manner that battery is sealed.The position of welding can be in the two ends of battery container or the optional position between two ends.Can be, battery container 1 be straight tubbiness, and port arranges welding cap 9, by being welded and fixed sealing, as shown in Figure 1 and Figure 2.Can be also, battery container 1 comprises two straight stavings, and two straight staving port docking are by being welded and fixed sealing.
Adopt the utility model, the useful space of inside battery can make the height of filling pole piece improve 1～5mm.Under the prerequisite of not changing cell integrated apparent size, effectively improve the capacity of battery.
The utility model adopts welding manner that battery is sealed.The position of welding can be in the two ends of battery container or the optional position between two ends.Can be, adopt welding cap sealed cell housing port, battery container be connected sealing with welding cap by the mode of welding.Can be also, battery container adopts two straight stavings, and two straight staving port docking are by the welding manner fixing seal.
The polar cap end is installed to be arranged on welding cap rivet 6.As shown in Figure 1, Ni-MH battery housing 1 is connected with the mode of welding cap 9 by welding.The through hole that diameter 1～10mm is arranged on welding cap 9.Sealing ring 7 pads pass through hole and rivet with welding cap 9 in rivet 6 outsides and together with rivet 6, and rivet 6 insulate by sealing ring 7 with welding cap 9.
The polar cap end is installed is arranged on the straight staving of battery case bottom.As shown in Figure 2, Ni-MH battery housing 1 is connected with the mode of welding cap 9 by welding.Battery container 1 has the through hole of diameter 1～10mm.Sealing ring 7 pads pass through hole and rivet with battery case 1 in rivet 6 outsides and together with rivet 6, and rivet 6 insulate by sealing ring 7 with battery container 1.
At outside batteries, by being welded to connect, at inside battery, rivet 6 is connected with a utmost point of battery by lug 8 rivet 6 with polar cap 5.
Safety valve is arranged in the optional position of rivet 6 or polar cap 5.
Polar cap 5 can be positive pole, also can be negative pole; The battery container 1 that matches with it can be negative pole, also can be positive pole.
The utility model has fundamentally changed the sealing process of ni-mh column secondary battery, has removed the space of slot rolling, has expanded the space proportion in battery case inside of battery pole piece, the battery of new technology encapsulation, and the inner useful space of shell can improve 5% left and right.
