Abstract
The present invention provides an electrode plate of battery. An active material in viscous liquid state is applied to an electricity collecting plate of a matel material, followed by drying, press rolling, and cutting, and an adhesive substance such as polyvinyl alcohol is applied for preventing separation of the active material from the side face of the edge of each electrode plate where the bonding power is weak relatively because of cutting. Thereby the active material applied to the electrode plate is precluded from separation.
Description
The present invention relates to the battery lead plate and the manufacture method thereof of battery, and be particularly related to the battery electrode plate that an adhesive layer comes off with the active material that prevents to apply in the end of battery lead plate, and manufacture method.
By a cylindrical tube 1, be contained in the charge member in the tube 1 with reference to 1, one typical battery of figure, and the lid 3 of sealed cylinder 1 is formed.Charge member 2 comprises a positive plate 2a who is covered with anode active material, a minus plate 2c who is covered with cathode active material, and between negative electrode 2c who is inserted in anode 2a, make the insulation board 2b of their mutually insulateds.Positive plate 2a, insulation board 2b and minus plate 2c stack togather in proper order, are wound up to put into tube 1.Then, lid 3 is sealed an openend of tube 1, and with its sealing.Anode and minus plate 2a and 2c (after this being referred to as battery lead plate) are the assembly of battery, make with different active materials by applying on metallics.
As shown in Figure 2, Chang Gui battery lead plate 10 is made up of metallics collector plate of making 11 and the active material layer 12 that applies on collector plate 11.In the manufacture process of the battery lead plate 10 with this structure, the metal collector plate 11 of porous immerses in the battery paste, forms this active material layer 12.Battery lead plate 10 with desired standard is by drying, rolling and the manufacturing of shear treatment operation.The active material that applies on collector plate 11 comprises battery charge or discharge active material, and it mixes with adhesive to increase the viscosity between the active material.When in order to the mixed proportion specific viscosity mixture of the active material of charge or discharge when high, charge efficiency just improves.The mixed proportion of active material determines in a scope, promptly applies when active material on collector plate 11 is treated as thin slice by rolling can not come off from collector plate 11.But when shearing battery lead plate 10 according to the size of bobbin, on the edge of shearing or on every side the position comes off or other position relatively easily, the bonding force at these positions may be relatively a little less than.The movable material layer 12 that is applied on it when positive plate 2a and minus plate 2c (see figure 1) is sheared and inserts insulating trip 2b between two pole plates 10, when being wound into scroll, the movable material layer 12 that is applied on the battery lead plate 10 is subjected to the shearing force that produced by the pressure between adjacent insulating trip and the battery lead plate, and, on the side at the edge of battery lead plate 10, this shearing force is big especially.Therefore, active material may come off from the side cut of two battery lead plates 10, and the active material that comes off can cause short circuit between two battery lead plates 10.And then short circuit reduces charge efficiency, reduces the life-span of battery.
In order to overcome the problems referred to above, the purpose of this invention is to provide a kind of battery lead plate and manufacture method thereof of battery, can prevent that the active material that applies on side, battery lead plate edge from coming off, therefore, can prevent short circuit, improve charge efficiency and extending battery life.
In order to achieve the above object, provide a cell electrode plate, it comprises: the collector plate of being made by the porous metals material; Apply the active material layer on collector plate; And be used to the adhesive layer that prevents that active material from coming off, and this adhesive layer applies on active material layer, and this active material layer applies on the lateral edge surface of collector plate.
In addition,, provide a kind of method of making battery electrode plate, comprise the steps: battery paste is applied on the collector plate of being made by the porous metals material, form an active layer for achieving the above object; Dry this active material makes it to be fixed on the collector plate; Rolling is covered with the collector plate of active material to predetermined thickness; Shearing collector plate is preset width and length; Apply adhesion substance, come off to prevent to apply at the lip-deep active material of the lateral edge of the battery lead plate that is sheared; And with the battery lead plate coiling, to make a charge member.
By being described in detail most preferred embodiment of the present invention with reference to the accompanying drawings, above-mentioned purpose of the present invention and advantage will be more apparent, wherein:
Fig. 1 is the element schematic exploded perspective view of a representative cells;
Fig. 2 cuts perspective view for a part, and simple table illustrates the conventional electrodes plate that battery adopts among Fig. 1; And,
Fig. 3 cuts perspective view for a part, and simple table illustrates the battery lead plate according to a most preferred embodiment of the present invention.
With reference to Fig. 3, the collector plate 21 that battery lead plate 20 according to the present invention is made by the porous metals material applies the active material layer 22 on collector plate 21, and the adhesive layer 23 of apposition on the active material layer 22 of side, collector plate 21 edge formed.Adopt apposition adhesive layer 23 can prevent to apply and come off, and should have strong adhesive power at the lip-deep active material of the lateral edge of collector plate 21.In the present embodiment, polyvinyl alcohol (PVA) is applied on active material layer 22, to increase the bonding force of active material.
When manufacturing has the battery lead plate 20 of this structure,,, make the collector plate of making by the porous metals material 21 as nickel-hydrogen cell or nickel-metal halide battery according to the pattern of battery.Next step applies pasty state and the moist active material of maintenance on collector plate 21, makes active material layer 22.
Then, the collector plate 21 that will be covered with active material falls the water evaporates in the active material 22 by a drying device.So the suction that is caused by evaporation can make active material be fixed on the collector plate 21.Next step, battery lead plate 20 is arrived predetermined thickness by pressure rolling, and considers charging capacity, and it is cut into a specific dimensions.
Then, these battery lead plates 20 through shearing are happened frequently abreast to be come, and for example the adhesive layer 23 of polyvinyl alcohol (PVA) applies on the lateral edge surface of this battery lead plate 20.This adhesive layer 23 is adhered to and applies on the lip-deep active material layer 22 of the lateral edge of battery lead plate 20, thereby the bonding force of active material increases.
After this, positive plate 2a, minus plate 2c (see figure 1) and the insulation board 2b that is clipped in the middle of their are wound up.Here, although shearing force concentrates on the lateral edge surface of battery lead plate 20, owing to active material layer 22 keeps by applying at the lip-deep adhesive layer 23 of the lateral edge of battery lead plate 20, so can prevent that active material from coming off.The charge member that winds up preferably can occupy the capacity of battery tube inner about 95%.
As mentioned above,, can avoid applying in the active material on the battery lead plate is being made the winding process of battery lead plate and come off, therefore, can prevent the short circuit of battery according to the present invention.Like this, improved battery charge efficient and prolonged life-span of battery.
