Embodiment
Below in conjunction with embodiment and contrast accompanying drawing the utility model is described in further details.
Embodiment one
As shown in Figure 2, be the structural representation of the battery battery core of present embodiment.Battery battery core 1 is rolled into the vortex shape cylindrical electrical core by positive pole 7 for preparing in advance and negative pole 8 therebetween with barrier film 9, pastes insulation spacer 3 by binding agent in the bottom of cylindrical electrical core then and is prepared from.Wherein, insulation spacer 3 is that thickness is 0.10-0.50mm, and diameter is the disk shape structure of the perforate of 13.8 ± 0.05mm, perforate be shaped as circle.The shape of perforate also can be square, pentagon, hexagon or other arbitrary shapes.Insulation spacer also can be the filled circles laminated structure.The material of insulation spacer 3 consists of polyvinyl chloride (Polyvinylchloride is called for short PVC).Its material is formed also can be for polypropylene, cling to a kind of material in the insulating material such as paper, paperboard and barrier film class material or multiple soon.
Because battery battery core 1 bottom is pasted with insulation spacer 3 by binding agent in the present embodiment; can play the effect of protection battery battery core 1; prevent that barrier film from giving a discount or the negative pole matrix produced by the extruding of box hat body wall cracked, make pack into the process of battery steel shell of battery battery core 1 simple to operation.On the other hand, after battery battery core 1 formed battery, battery battery core 1 may occur that the negative pole powder agglomates drops, the phenomenon of both positive and negative polarity bottom dry linting.When the bottom of negative pole powder agglomates or both positive and negative polarity dry linting is slipped to battery bottom, on the binding agent that sticks on insulation spacer 3 that the powder agglomates of landing or dry linting will be firm, can between battery battery core and insulation spacer, not take place laterally to move, making powder agglomates or dry linting touch anodal probability with negative pole simultaneously reduces significantly, thereby reduce the probability that the battery of making becomes zero battery, improve the performance of the battery of making.
Embodiment two
As shown in Figure 3, be the structural representation of column type Ni-MH battery in the present embodiment.The column type Ni-MH battery is that nominal capacity is the AA column type Ni-MH battery of 2200mAh, directly putting into internal diameter by the battery battery core in the execution mode one 1 is in the cylindrical steel 2 of 13.8 ± 0.05mm, seals after placing dough sheet 4, notes electrolyte, covering the block 5 of being furnished with sealing ring 6 and makes.Battery battery core 1 in the present embodiment, is directly to paste insulation spacer 3 backs to form after anodal and negative pole folder are rolled into the vortex shape cylindrical electrical core with barrier film.
For the column type Ni-MH battery in the comparison present embodiment and the performance of existing column type Ni-MH battery, comparative example is set.The column type Ni-MH battery also is the AA column type Ni-MH battery of 2200mAh for nominal capacity in the comparative example, and the difference of itself and present embodiment is that insulation spacer is not pasted in the bottom of its battery battery core.Comparative result sees the following form.
Data shown in the table are comparisons of the statistics of the Ni-MH battery that battery battery core prepares in Ni-MH battery and the prior art of battery battery core preparation in the present embodiment.The quality product rate of AA2200 high-capacity nickel-hydrogen battery has improved 0.44% in the present embodiment, and zero electric rate reduces by 0.201%, and the low pressure rate reduces by 0.132%.As seen because the battery battery core that the column type Ni-MH battery in the present embodiment adopts bottom is pasted with insulation spacer, so the fraction defective of the battery of making descends to some extent.This reduction to battery defective products rate can reduce battery cost to a certain extent, and improves the performance of battery, has also reduced the waste to efficient resource simultaneously.
Embodiment three
The difference of present embodiment and execution mode two is: the battery battery core 1 in the present embodiment is earlier insulation spacer 3 to be pressed into cylindrical steel 2, after the cylindrical steel 2 of then the vortex shape cylindrical electrical core that is rolled into being packed into, vortex shape cylindrical electrical core and insulation spacer 3 are pasted formed.
As shown in Figure 4, the column type Ni-MH battery is that nominal capacity is the AA column type Ni-MH battery of 2200mAh, internal diameter is the battery battery core of placing in the cylindrical steel 2 of 13.8 ± 0.05mm in the execution mode one 1, and the battery battery core positive terminal is placed dough sheet 4, and cap seal has the block 5 of being furnished with sealing ring 6 on it.
Column type making nickel hydrogen battery mode in the present embodiment is: at first, positive pole 7 and negative pole 8 therebetween that prepare in advance are rolled into the vortex shape cylindrical electrical core with barrier film 9; Then, insulation spacer 3 is packed into evenly coat the skim binding agent on its surface before the cylindrical steel 2; Then, will pack in the cylindrical steel 2 that this insulation spacer 3 is housed by the vortex shape cylindrical electrical core that anodal 7, negative pole 8 and barrier film 9 are rolled into.After packing into, vortex shape cylindrical electrical core and insulation spacer 3 firmly are pasted together the battery battery core 1 that forms in the execution mode one.Afterwards, seal after slot rolling, notes electrolyte, lid have been furnished with the block 5 of sealing ring 6, making nominal capacity is the AA column type Ni-MH battery of 2200mAh again.
Column type Ni-MH battery in the present embodiment; its battery battery core 1 bottom is pasted with insulation spacer 3; can play the effect of protection battery battery core 1; can paste simultaneously powder agglomates and both positive and negative polarity bottom dry linting that battery battery core drops; thereby the column type Ni-MH battery of making becomes the probability of zero battery and reduces, and the performance of battery improves.
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, make some substituting or obvious modification under the prerequisite of the utility model design not breaking away from, and performance or purposes are identical, all should be considered as belonging to protection range of the present utility model.
