Abstract
The utility model discloses a positive pole steel shell of a button cell and the button cell. According tothe technical scheme, a convex point at the middle part of the circular bottom surface of the positive pole steel shell of the button cell is pressed towards the interior of the positive pole steel shell. The button cell comprises the positive pole steel shell, and the convex point at the middle part of the circular bottom surface of the positive pole steel shell is pressed towards the interior of the positive pole steel shell. The positive pole steel shell disclosed by the utility model can freely separate out and immerse an electrolyte in the cell during charge and discharge processes, improve the utilization rate of nickel hydroxide and achieve the effects of reducing cost and saving resources by changing the positive pole steel shell of a button type hydrogen-nickel cell to the structure with the convex point.
Description
Technical field
The utility model belongs to the button cell technical field, is specifically related to a kind of Snap-type cell positive box hat and button cell.
Background technology
the bottom of conventional button Ni-H cell positive pole steel shell is planar structure, during assembling, positive plate and positive pole steel shell bottom is plane-plane contact, after adding electrolyte, electrolyte is difficult to infiltrate into whole positive plate, cause in positive plate the utilance of nickel hydroxide low, in addition, deviation due to utmost point group thickness, part battery assembling elasticity is less, cause the individual cell internal resistance larger, also cause simultaneously the individual cell charging/discharging voltage unstable, concrete manifestation is the charging and discharging curve indentation of battery, affected the stable output of battery electric current and voltage when reality is used, cause electrical appliance the erroneous judgement of battery performance to be affected the use of electrical equipment.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of Snap-type cell positive box hat, use this Snap-type cell positive box hat as electrolyte the infiltration of positive plate with the condition that provides is provided, also improved the consistency of button cell internal resistance simultaneously.
Another technical problem that the utility model solves has been to provide a kind of button cell, and the electrolyte of this button cell is freely separated out in charge and discharge process and immerses, and makes nickel hydroxide have higher interest rate, has reduced production cost and has also saved the energy.
The technical solution of the utility model is: a kind of Snap-type cell positive box hat is characterized in that: the middle part of described positive pole steel shell rounded bottom surface is pressed with salient point to the inside of positive pole steel shell.
A kind of button cell described in the utility model comprises positive pole steel shell, it is characterized in that: the middle part of described positive pole steel shell rounded bottom surface is pressed with salient point to the inside of positive pole steel shell.
The utility model is by making button Ni-H cell positive pole steel shell into the structure with salient point, can make the electrolyte in battery freely separate out in charge and discharge process and immerse, improved the utilance of nickel hydroxide, reached the effect that reduces costs, economizes on resources, simultaneously make again positive plate tightr with contacting of positive pole steel shell, solved the poor and unsettled problem of charging/discharging voltage of consistency of internal resistance of battery, moreover freely the infiltrating and flow and improved other performance of battery of electrolyte, as the raising of high rate during charging-discharging and the raising of discharge voltage plateau etc.
Description of drawings
Fig. 1 is the structural representation of present Snap-type cell positive box hat; Fig. 2 is the structural representation of the utility model Snap-type cell positive box hat; Fig. 3 is the structural representation of button cell of the present utility model.
Drawing explanation: 1, negative cover, 2, tapered coil spring, 3, punching pad or burr pad, 4, cushion rubber, 5, negative plate, 6, barrier film, 7, positive plate, 8, positive pole steel shell, 9, the pole plate group, 10, salient point.
Embodiment
Describe by reference to the accompanying drawings embodiment in detail.The MH-Ni buckle type battery is combined by pole plate group 9, tapered coil spring 2, negative cover 1, cushion rubber 4 and positive pole steel shell 8, this pole plate group 9 by nickel positive electrode plate 7, the hydrogen storage alloy negative plate 5 of brace structure or single chip architecture and be arranged on positive plate and negative plate between barrier film 6 form.Concrete compound mode is: (1), first with flange negative cover 1 and and band clasp cushion rubber 4 combine; (2), tapered coil spring 2 great circles are put into combination cushion rubber 4 towards negative cover 1 direction, then punching pad or burr pad 3 be placed on tapered coil spring 2 (whether put the punching pad or the burr pad depends on the battery cathode basis material); (3), negative plate 5, barrier film 6 and positive plate 7 cross foldings are become pole plate group 9 put in the assembly of first two steps formation; (4), filling electrolyte; (5), will be buckled in the positive pole steel shell 8 of salient point 10 structures on the combinations thereof body that added electrolyte; (6), sealing is the moulding battery.Because the middle part of the rounded bottom surface of positive pole steel shell 8 is pressed with salient point 10 to the inside of positive pole steel shell 8, make the electrolyte in battery can freely separate out and immerse in charge and discharge process, improved the utilance of nickel hydroxide in positive plate 7, gram volume improves 8%, weight saving is more than 10%, the charging voltage platform is lower, eliminated the unsettled problem of individual cell charging/discharging voltage, make the battery charging and discharging curve more level and smooth, internal resistance is more even, reduced the percent defective of battery, therefore battery cycle life also promotes more than 15%.
Claims (2)
