Abstract
The utility model relates to a cylindrical nickel -hydrogen battery, including box hat (9), electric core, in the box hat electrolyte electric core coil by the order of positive plate (2), diaphragm (3), negative pole piece (1) from inside to outside and form, go up with box hat (9) wall contact side negative pole piece (1) does not have the hydrogen of storage alloy powder. Cost is reduced it is extravagant to reduce raw and other materials. Simultaneously, because the space that nothing storage hydrogen alloy powder was vacateed can be used for positive pole and negative pole front end to pack the volume ratio capacity that more powders improve the battery again. In addition, scrape the direct and box hat inner wall contact of base member steel band behind the powder, reduced the inside impedance of battery.
Description
Technical field
This utility model relates to Ni-MH battery field, particularly to a kind of cylinder-type nickel-metal hydride battery.
Background technology
Cylinder-type nickel-metal hydride battery is a kind of Ni-MH battery being widely used, and has high-energy, long-life, the feature such as pollution-free, thus is widely used.
Existing cylinder-type nickel-metal hydride battery structure is generally the monolayer battery case of nickel plating steel or stainless steel, nickel plating steel or stainless steel monolayer battery cap, battery core be from inside to outside positive plate, barrier film, negative plate sequential volume around forming.Particularly in negative plate wet process technique, wet method pulling-on piece is to be evenly coated with hydrogen storing alloy powder slurry on the two sides of steel band, makes powder be uniformly distributed matrix both sides and makes negative plate.Separating with barrier film in the middle of negative plate and positive plate, one cylinder of rolled rear formation, cylindrical outmost turns is negative pole, direct and box hat contact internal walls.Negative pole participates in the electrochemical reaction of electrode hardly with this part hydrogen bearing alloy powder in the one side of box hat contact internal walls, do not play the effect of the power supply capacity of electric current, cause the waste of this part powder, and result also in the waste on this segment space, be unfavorable for the raising of Ni-MH battery capacity.
Because, it is necessary to for the deficiency of existing conventional art, optimize existing cylinder-type nickel-metal hydride battery further, to reduce waste of material, reduce manufacturing cost, the inner space of Appropriate application battery, improve the volume and capacity ratio of battery.
Utility model content
One of technical problem to be solved in the utility model is the electrochemical reaction that the hydrogen bearing alloy powder that existing cylinder-type nickel-metal hydride battery negative plate contacts on side with box hat wall participates in electrode hardly, causes waste and the space waste of this part powder；Another problem is that existing battery can not work in extreme temperature conditions.
In order to solve the problems referred to above, the following technical scheme of the bright offer of this law:
. a kind of cylinder-type nickel-metal hydride battery, including box hat, battery core, the electrolyte in box hat, described battery core from inside to outside by positive plate, barrier film, negative plate sequential volume around forming, it is characterized in that, described negative plate contacts on side without hydrogen bearing alloy powder with box hat wall.
Further, described negative plate is the steel strip substrate of the hydrogen bearing alloy powder on a face after striking off wet method pulling-on piece.
Compared with prior art, the beneficial effects of the utility model are: negative plate contacts without hydrogen bearing alloy powder on side with box hat wall, reduce cost and reduce waste of raw materials.And, scrape the matrix steel band after powder directly and box hat contact internal walls, reduce internal battery impedance.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is cylinder-type nickel-metal hydride battery structure sectional view.
Detailed description of the invention
In order to clearly disclose technical solutions of the utility model, it is described further below in conjunction with the accompanying drawings.It should be appreciated that in the following description, " on ", D score, " interior ", the term such as " outward " be only used for representing the most indicated direction.
As it is shown in figure 1, include box hat 9, it being arranged on the electrolyte in box hat 9, negative plate 1, positive plate 2, barrier film 3) negative plate 1 and positive plate 2 isolated by barrier film, Intermediate gasket 4, steam vent 5, block 6, sealing ring 7, lug 8.The hydrogen bearing alloy powder that negative plate 1 contacts on side with box hat 9 wall is stripped off.Scrape the matrix steel band after powder directly and box hat contact internal walls, reduce internal battery impedance.
Above-described is only principle of the present utility model and preferred embodiment.Should be understood that, although disclosing preferred embodiment of the present utility model and accompanying drawing for explanation the purpose of this utility model, but person skilled in the art, without departing from this utility model and appended spirit and scope by the claims, can make various replacement, change and retouch.Therefore on the basis of this utility model principle, other modification some made, also should be regarded as protection domain of the present utility model.
Claims (3)
1. a cylinder-type nickel-metal hydride battery, including box hat (9), battery core, the electrolyte in box hat, described battery core from inside to outside by positive plate (2), barrier film (3), negative plate (1) sequential volume around forming, it is characterized in that, described negative plate (1) contacts on side without hydrogen bearing alloy powder with box hat (9) wall.
