Abstract
The utility model belongs to the technical field of ni-mh batteries, and provides a ni-mh high capacity battery anode plate, which comprises two cuboids with a certain width difference, wherein the heads and the tails of the two cuboids are connected. According to the ni-mh high capacity battery anode plate, an electrical core with small width is arranged on an outer layer after winding, the end of an anode is lower, a shell wall of a battery is not easy to contact and press down the anode after a rolling slot is sealed, thereby reducing the rate of short circuit during the use process of the battery, leading the safety of the battery to be greatly increased, and reducing the difficulty of operation demands for a winding worker.
Description
Technical field
The utility model relates to Ni-MH battery, relates in particular to a kind of ni-mh high-capacity battery positive plate.
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.Referring to Fig. 1, positive plate is the equally wide cuboids in front and back, and its length is L, and width is D.This pole piece requires tighter for the high-capacity battery coiling, employee's qualification is very high, and pole piece walks slightly and just easily causes electric core terminal anodal higher, seals back battery short circuit probability and increases, and also strict to the slot rolling tolerance, the battery short circuit probability that also easily causes bigger than normal increases.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of Ni-MH battery pole piece that the battery short circuit probability is little and the coiling difficulty is low that makes is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of ni-mh high-capacity battery positive plate constitutes by two cuboids with certain width difference are end to end.
Described stand out is 0.5～1.0mm.
The beneficial effects of the utility model: behind the electric core winding width little at skin, anodal end is shorter, slot rolling seals back battery shell wall and is difficult for bumping, overwhelming positive pole, thereby reduce the probability of short circuit in the battery use, make the very big raising of fail safe of battery, and require difficulty to reduce coiling worker operation.
Description of drawings
Fig. 1 is existing positive plate schematic diagram.
Fig. 2 is the positive plate schematic diagram according to the Ni-MH battery of the utility model preferred embodiment.
Embodiment
Referring to Fig. 2, a kind of positive plate for nickel-hydrogen cell 10 comprises inequality two sections of width, and the width of the leading portion 11 of broad is D, and the width of narrower rear 12 is d.Lug 20 is fixed on the leading portion 11.The difference of D and d is determined by concrete battery structure, is preferably 0.5-1.0mm.The length N of rear 12 is determined by the length of the outmost turns of electric core.
The different needed breach with rear 12 width of leading portion 11 can be formed by punching press in the utility model, can largely reduce high-capacity battery at the pole piece rear towards breach and seal box hat slot rolling place's bruising afterwards to anodal probability, anodal end is shorter behind the electric core winding, slot rolling seals back battery shell wall and is difficult for bumping, overwhelming positive pole, thereby reduce the probability of short circuit in the battery use, make the very big raising of fail safe of battery.And require difficulty to reduce to coiling worker operation.
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. a ni-mh high-capacity battery positive plate is characterized in that: constitute by two cuboids with certain width difference are end to end.
2. ni-mh high-capacity battery positive plate according to claim 1 is characterized in that: described stand out is 0.5～1.0mm.
