Abstract
The utility model discloses a negative pole cover of a hydrogen-nickel button cell and the hydrogen-nickel button cell. According to the technical scheme, the edge of the negative pole cover of the hydrogen-nickel button cell is of a turned-over edge structure. The hydrogen-nickel button cell comprises a negative pole cover, and the edge of the negative pole cover is of a turned-over edge structure. The negative pole cover disclosed by the utility model can increase the section of a seal of the hydrogen-nickel button cell, further increase the pressure of the seal by increasing the sealing section, improve the sealing property of the cell and reduce the possibility of leakage and alkaline climbing of the cell by designing the edge of the negative pole cover of the hydrogen-nickel button cell into the turned-over edge structure.
Description
Technical field
The utility model belongs to the button cell technical field, is specifically related to a kind of MH-Ni buckle type battery cathode lid and MH-Ni buckle type battery.
Background technology
The MH-Ni buckle type battery is because its volume is little, and its sealing can not be adopted the slot rolling enclosuring structure as cylindrical battery, can only realize by battery case cap the sealing of battery to the trace compression of sealing ring.The enclosuring structure of MH-Ni buckle type battery belongs to the line style sealing at present, adds that sealing pressure is again less, and the alkali phenomenon of leakage easily appears climbing in battery.The just current enclosuring structure of necessary change of alkali problem is climbed in the leakage that therefore, solve the MH-Ni buckle type battery.The negative cover that has at present turnup structure is only used in the enclosuring structure of disposable button cell, and uses the negative cover with turnup structure also there is no research and the report of related fields at home and abroad on the MH-Ni buckle type battery.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of MH-Ni buckle type battery cathode lid, the sealing cross section of using this negative cover can increase battery in Ni-H cell, and the increasing of sealed section has increased sealing pressure, has improved the sealing of battery.
Another technical problem that the utility model solves is to provide can a kind of MH-Ni buckle type battery, and this button cell has sealing preferably, can effectively prevent the leakage of electrolyte.
The technical solution of the utility model is: a kind of MH-Ni buckle type battery cathode lid is characterized in that: the edge of described MH-Ni buckle type battery cathode lid is turnup structure.
A kind of MH-Ni buckle type battery described in the utility model comprises negative cover, it is characterized in that: the edge of described negative cover is turnup structure.
The utility model has increased the sealing cross section of MH-Ni buckle type battery by being turnup structure to MH-Ni buckle type battery cathode lid edge designs, the increasing of sealed section has increased sealing pressure, has improved the sealing of battery, has reduced the possibility that battery leakage is climbed alkali.
Description of drawings
Fig. 1 is the structural representation of present MH-Ni buckle type battery cathode lid; Fig. 2 is the structural representation of the utility model button cell cathode cover; Fig. 3 is the structural representation of button cell of the present utility model.
Drawing explanation: 1, negative cover, 2, flange, 3, tapered coil spring, 4, punching pad or burr pad, 5, cushion rubber, 6, negative plate, 7, barrier film, 8, positive plate, 9, positive pole steel shell, 10, the pole plate group.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.A kind of MH-Ni buckle type battery cathode lid, the edge of described MH-Ni buckle type battery cathode lid 1 is flange 2 structures.MH-Ni buckle type battery described in the utility model comprises negative cover 1, and the edge of described negative cover 1 is flange 2 structures.The MH-Ni buckle type battery is combined by pole plate group 10, tapered coil spring 3, negative cover 1, cushion rubber 5 and positive pole steel shell 9, this pole plate group 10 by nickel positive electrode plate 8, the hydrogen storage alloy negative plate 6 of brace structure or single chip architecture and be arranged on positive plate and negative plate between barrier film 7 form.Concrete compound mode is: (1), first will combine with negative cover 1 and the band clasp cushion rubber 5 of flange 2 structures; (2), tapered coil spring 3 great circles are put into combination cushion rubber 5 towards negative cover 1 direction, then punching pad or burr pad 4 be placed on tapered coil spring 3 (whether put the punching pad or the burr pad depends on the battery cathode basis material); (3), negative plate 6, barrier film 7 and positive plate 8 cross foldings are become pole plate group 10 put in the assembly of first two steps formation; (4), filling electrolyte; (5), positive pole steel shell 9 is buckled on the combinations thereof body that added electrolyte; (6), sealing is moulding MH-Ni buckle type battery.The utility model makes the edge of negative cover 1 into flange 2 structures, making the draw-in groove of the flange 2 of negative cover 1 and cushion rubber 5 become face contacts, so just increased sealing pressure, improved the sealing of battery, solved simultaneously the leakage that often occurs due to MH-Ni buckle type battery cathode lid 1 distinctive structure and climbed the alkali problem.The MH-Ni buckle type battery that uses flange 2 structure negative cover 1 is being carried out limit test 1C when overcharging, the phenomenon of leakage did not appear in 90 minutes in the 1C charging, carrying out 45 ℃ of high temperature and shelving for a long time the alkali phenomenon not occurring climbing in the time of half a year, the problem that leakage often occurred and climb alkali during high temperature is shelved summer with regard to having solved the MH-Ni buckle type battery like this.
Claims (2)
1. a MH-Ni buckle type battery cathode is covered, and it is characterized in that: the edge of described MH-Ni buckle type battery cathode lid is turnup structure.
