Abstract
The utility model provides a kind of Novel nickel-hydrogen battery, comprise positive plate, negative plate and barrier film, three is contour, positive plate, barrier film and negative plate sequentially arrange successively from inside to outside and are wound into battery core, and positive plate and barrier film and negative plate are all staggered and arrange, barrier film wrong 1mm ± 0.5mm more downward than positive plate, negative plate wrong 2mm ± 0.5mm more downward than barrier film, positive plate and negative plate are all welded with flow collection sheet.Because the utility model battery adopts Double End solder technology, electric current is collected by both positive and negative polarity flow collection sheet, reduce the range ability of electric current in pole plate, reduce the internal resistance of cell, improve the power-performance of battery, tradition pole Battery pack internal resistance is generally 5 to 10m Ω, and the internal resistance of the utility model battery is generally 3 to 6m Ω; During the group winding of end face welding pole, because dislocation winding does not have the impact of positive and negative electrode lug and tab welding point, group winding in pole is neat, and short circuit ratio decline 1-2%, battery security significantly improves.
Description
Technical field
The utility model belongs to Ni-MH battery field, particularly relates to a kind of Novel nickel-hydrogen battery.
Background technology
Nearly hundreds of family of producer of current domestic battery production.Be wherein many with Ni-MH battery and lithium ion battery, ickel-cadmium cell is restricted owing to polluting its production, its electrical property again comparatively Ni-MH battery and lithium ion battery have larger gap, so in a lot of field by Ni-MH battery and lithium ion battery replace; Although and lithium ion battery is widely used on mobile phone, ipad and small-sized electric appliance.But due to its deficiency in fail safe, power discharge performance and low temperature serviceability etc., combine particularly branched combinationally use time still have larger danger, therefore the application under the particular surroundingss such as colliery is still prohibited, within the quite a long time, and still cannot replacement nickel hydrogen battery.The application of Ni-MH battery on mining product especially has incomparable performance advantage.
The many employings of existing Ni-MH battery put lug of burn-oning on pole plate, and then encapsulate, this structure electric current range ability in pole plate is long, and internal resistance is large, how power of battery poor performance, design the problem that the good Novel nickel-hydrogen battery structure of a kind of power of battery performance becomes those skilled in the art's research.
Utility model content
First problem to be solved in the utility model is to provide a kind of Novel nickel-hydrogen battery.
For solving the problem, the technical solution adopted in the utility model: a kind of Novel nickel-hydrogen battery, comprise positive plate, negative plate and barrier film, described positive plate, described negative plate and described barrier film three contour, described positive plate, described barrier film and described negative plate sequentially arrange successively from inside to outside and are wound into battery core, and described positive plate and described barrier film and described negative plate are all staggered and arrange, described barrier film wrong 1mm ± 0.5mm more downward than described positive plate, described negative plate wrong 2mm ± 0.5mm more downward than described barrier film, described positive plate and described negative plate are all welded with flow collection sheet.
Described flow collection sheet is evenly provided with multiple flanging by dispersing to external radiation near circle centre position and welds air drain.
Described flanging is strip or zigzag.
Described barrier film wrong 1mm more downward than described positive plate, described negative plate wrong 2mm more downward than described barrier film.
Described flow collection sheet and corresponding pole plate are that spot welding connects.
Flow collection sheet on described positive plate by connecting band with block be connected, the flow collection sheet on described negative plate and box hat spot-welded together.
Upper end and the lower end of described negative plate of described positive plate are equipped with the electrodes conduct plain edge being connected flow collection sheet.
The advantage that the utility model has and good effect are: because the utility model battery adopts Double End solder technology, electric current is collected by both positive and negative polarity flow collection sheet, reduce the range ability of electric current in pole plate, reduce the internal resistance of cell, improve the power-performance of battery, tradition pole Battery pack internal resistance is generally 5 to 10m Ω, and the internal resistance of the utility model battery is generally 3 to 6m Ω; During the group winding of end face welding pole, because dislocation winding does not have the impact of positive and negative electrode lug and tab welding point, group winding in pole is neat, and short circuit ratio decline 1-2%, battery security significantly improves.

In figure: 1 positive plate 2 barrier film 3 negative plate 4 flow collection sheet 5 connecting band 6,7 box hats 41 of blocking a shot weld air drain.
Embodiment
Now with reference to the accompanying drawings comparatively detailed description is carried out to the utility model, as Figure 1-4, a kind of Novel nickel-hydrogen battery, comprise positive plate 1, negative plate 3 and barrier film 2, described positive plate 1, described negative plate 3 and described barrier film 2 three contour, described positive plate 1, described barrier film 2 and described negative plate 3 sequentially arrange successively from inside to outside and are wound into battery core, and described positive plate 1 is all staggered with described barrier film 2 and described negative plate 3 and arranges, described barrier film 2 wrong 1mm ± 0.5mm more downward than described positive plate 1, described negative plate 3 wrong 2mm ± 0.5mm more downward than described barrier film 2, described positive plate 1 and described negative plate 3 are all welded with flow collection sheet 4.Because the utility model battery adopts Double End solder technology, electric current is collected by both positive and negative polarity flow collection sheet 4, reduce the range ability of electric current in pole plate, reduce the internal resistance of cell, improve the power-performance of battery, tradition pole Battery pack internal resistance is generally 5 to 10m Ω, and the internal resistance of the utility model battery is generally 3 to 6m Ω.
Further, in order to improve security performance, described flow collection sheet 4 being evenly provided with multiple flanging by dispersing to external radiation near circle centre position and welding air drain 41.
Further, in order to improve the bonding strength of flow collection sheet 4 and pole plate, described flanging strip or zigzag.Facilitate spot welding.
