Description
Technical field
The present invention relates to field of batteries, be specially a kind of ultra-low volume Ni-MH battery and preparation method thereof.
Background technology
The execution that issues owing to the environmental protection instruction; A lot of producers of low-cost cadmium nickel and lead-acid battery that use need Ni-H cell, do not have big variation but precondition is cost and volume, if because change in volume; Product mold and supporting component need design again; Can increase very big cost to battery user, therefore, the Ni-H cell of our production low capacity under the volume of former ickel-cadmium cell of this specification requirement.
There is following shortcoming in constancy of volume, the capacity low Ni-H cell of ickel-cadmium cell that compares again, and fail safe is unstable, and the material cost saving is not got off, battery performance instability etc.
Summary of the invention
In order to overcome above deficiency, the present invention mainly is used as the guarantee that is reduced to this and increases fail safe with big or small box hat cover.
Technical scheme of the present invention is: the ultra-low volume Ni-MH battery; It comprises the standard cell box hat; It is characterized in that: be with the interior firm shell adaptive in the standard cell box hat with it; Positive pole on positive pole on the standard cell box hat and the interior box hat links to each other through the anodal stator that is connected, and it is continuous that the negative pole on the standard cell box hat and negative pole on the interior box hat are connected stator through negative pole; In described box hat be placed in the standard box hat and with its welding.
Special spot-welding equipment is adopted in described welding, and this spot-welding equipment is used for the welding of big or small box hat, and an electrode of equipment is fixing ordinary copper capillary; Another electrode is square copper electrode; This electrode can be on the slideway of bottom move left and right so that when it is removed, little box hat inner bottom surface is aligned with the brazing pin; Then square copper electrode is moved to big box hat below, aligned position is carried out spot welding.
The preparation method of ultra-low volume Ni-MH battery, it may further comprise the steps:
(1) customization is fit to the interior box hat of capacity;
(2) produce battery, both positive and negative polarity and barrier film are assemblied in the little box hat, and fluid injection is sealed;
(3) using spot-welding equipment that little box hat is enclosed within the big box hat welds.
Special spot-welding equipment is adopted in described welding, and this spot-welding equipment is used for the welding of big or small box hat, and an electrode of equipment is fixing ordinary copper capillary; Another electrode is square copper electrode; This electrode can be on the slideway of bottom move left and right so that when it is removed, little box hat inner bottom surface is aligned with the brazing pin; Then square copper electrode is moved to big box hat below, aligned position is carried out spot welding.
Beneficial effect of the present invention is: outward appearance satisfies client's dimensional requirement, the inner raw material of saving, and battery performance is stable, and fail safe is good.
Description of drawings
Fig. 1 is embodiment 1 a battery structure sketch map;
Fig. 2 is embodiment 1 a battery capacity curve chart;
Fig. 3 is embodiment 1 a spot welding machine structure chart;
Wherein 1, the standard cell box hat, 2, interior box hat, 3, the anodal stator that connects, 4, negative pole connects stator.
Embodiment
With Ni-MH AA500 battery is example, and the AA Standard box hat is of a size of φ 13.9 * φ 13.5 * 49.0mm, and best inner both positive and negative polarity fitted position is:
Anodal: long 80 ~ 90 * wide 38.94mm;
Negative pole: long 115 ~ 125 * wide 38.94 ~ 40.71mm;
Battery capacity is 3 ~ 3.6 times of 500mAh at 1500 ~ 1800mAh.
If shorten the both positive and negative polarity size, battery utmost point group is loose especially in box hat, has strengthened contact resistance, and battery performance descends; If the both positive and negative polarity narrowed width, battery utmost point group jumps up and down in box hat, has a strong impact on the fail safe of battery.Therefore, the special sized of the present invention is that the interior box hat 2 of φ 10.12 * φ 9.8 * 47.5mm is applied mechanically and is welded in the AA Standard box hat 1, makes battery apparent size standard, and both positive and negative polarity is of a size of:
Anodal: long 35 ~ 40 * wide 35.0mm;
Negative pole: long 48 ~ 55 * wide 35.4mm;
Both positive and negative polarity and barrier film are assemblied in the little box hat, and fluid injection is sealed.
For strengthening being connected of little box hat and big box hat, the present invention transforms spot-welding equipment to reach the welding purpose, and it is following to transform spot-welding equipment: special spot-welding equipment is adopted in described welding; This spot-welding equipment is used for the welding of big or small box hat; An electrode of equipment is fixing ordinary copper capillary, and another electrode is square copper electrode, this electrode can be on the slideway of bottom move left and right; So that when it is removed; Little box hat inner bottom surface is aligned with the brazing pin, then square copper electrode is moved to big box hat below, aligned position is carried out spot welding.
Because of little box hat and big box hat firm welding good conductivity, battery performance can not be affected.
The internal resistance of cell≤25m the Ω of the present invention preparation, six months self discharge≤25%, its capacity curve are as shown in Figure 2.
