Abstract
The utility model belongs to the technical field of nickel-metal hydride batteries, and provides a nickel-metal hydride high-capacity cylindrical battery, comprising a shell, and an anode piece, a cathode piece, a diaphragm and electrolyte which are arranged in the shell, wherein one tail end of the anode piece takes the shape of a wedge with an inclined surface. According to the nickel-metal hydride battery, as the shape of the tail end of the anode has certain inclination, when in winding, the wedge-shaped surface faces downwards, so as to just fill an empty space at the tail end, thus improving the space utilization rate; and simultaneously, a battery cell has better degree of circularity, the steel shell has less deformation after entering the shell, and subsequent working procedures of slotting and sealing have higher finished product ratio.
Description
Technical field
The utility model relates to Ni-MH battery, relates in particular to a kind of ni-mh high-capacity battery.
Background technology
Ni-MH battery is used in people's daily life widely at present, to the higher portable electrical appliance that consumes energy, the battery volume capacity has been proposed higher requirement, therefore how to improve the volume and capacity ratio of cylinder-type nickel-metal hydride battery, prolong the task of top priority that be the exploitation of ni-mh high-capacity battery the service time of charging once as far as possible.
Ni-MH battery is made up of positive pole, negative pole, barrier film, and nickel electrode comprises that nickel foam sheet and coating are filled in the active material in the nickel foam, after roll squeezer is rolling, directly cuts into the cuboid pole piece with wafer separator.In the ni-mh high-capacity battery, be one of main task in unit volume, filling more active material.The 2-2.5 that general positive plate thickness is negative pole thickness doubly, between anodal about 0.70-0.75mm, about the about 0.30mm of negative pole thickness, after reeling thus, at the terminal about 1.0mm neutral gear that produces of reeling, pole piece is round, and tighter, and the requirement of high-capacity battery box hat wall is thinner, oval phenomenon appears in the back box hat that occurs easily reeling, the coiling short circuit ratio is higher, to back operation jet-bedding, seals rate of finished products and produces considerable influence.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, improves the back pole piece circularity of reeling, and makes the terminal barrier film of reeling bear pressure and reduces, and improves the ni-mh high power capacity cylindrical battery of the yields of battery winding short circuit ratio and sealing process.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of ni-mh high power capacity cylindrical battery comprises shell and is arranged on wherein positive/negative plate, barrier film and electrolyte that an end of described positive plate is the wedge that an inclined-plane is arranged.
Described inclined-plane and bottom surface angle are the 30-60 degree.
Positive plate of the present utility model is to carry out edging and handle and to form by cutting pole piece.
The beneficial effects of the utility model: because of anodal terminal end shape has certain gradient, during coiling, wedge faces down, just fill terminal neutral gear, improve space availability ratio, electric core circularity is better simultaneously, after going into shell, box hat distortion is less, back operation jet-bedding and to seal rate of finished products higher.
Description of drawings
Fig. 1 is the cross-sectional view according to the positive plate of the Ni-MH battery of the utility model preferred embodiment.
Fig. 2 is the positive plate front view according to the Ni-MH battery of the utility model preferred embodiment.
Embodiment
Referring to Fig. 1-2, a kind of ni-mh high power capacity cylindrical battery comprises shell and is arranged on wherein positive plate, negative plate, barrier film and electrolyte.Positive plate 10 main parts are rectangular shapes, and one is terminal for having the wedge on an inclined-plane.The angle α of inclined-plane and bottom surface is the 30-60 degree, is determined by the thickness of positive plate and the volume of garden core.
Battery when assembling, because of anodal terminal end shape to certain gradient, during coiling, wedge faces down, and just fills terminal neutral gear, improves space availability ratio, electric core circularity is better simultaneously, go into shell after, the box hat distortion is less, back operation jet-bedding and to seal rate of finished products higher.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, do not breaking away under the prerequisite of the utility model design, make concrete change or change and all belong to protection range of the present utility model.
Claims (2)
1. ni-mh high power capacity cylindrical battery comprises shell and is arranged on wherein positive/negative plate, barrier film and electrolyte that it is characterized in that: an end of described positive plate is the wedge that an inclined-plane is arranged.
2. ni-mh high power capacity cylindrical battery according to claim 1 is characterized in that: described inclined-plane and bottom surface angle are the 30-60 degree.
