Abstract
A secondary battery is composed of positive and negative plate electrodes into which active substance is filled, isolating membrane and electrolyte. The production procedure of said plate electrode includes magnetizing orientation. Its advantages are consistent current direction, high charge and discharge effect and transform efficiency, and long service life.
Description
The present invention relates to a kind of production method of battery, relate in particular to a kind of production method of secondary cell.
Battery is made of positive active material, negative electrode active material, barrier film and electrolyte.Its electrochemical reaction is carrying out at the interface positive active material, negative electrode active material and electrolyte three.People to the requirement of battery are in actual use: the voltage in electromotive force height, when discharge reduces little over time, weight ratio volume or volume ratio volume and utilance is big, storage property and excellent in te pins of durability; For secondary cell, the voltage when also requiring charging rises little, and it is big that current efficiency is wanted.But, present commercially available battery, especially secondary cell, because therefore the problem of its production method all exists such-and-such shortcoming, for example lead accumulator and alkaline battery, though the discharging and recharging number of times and can reach 50～200 circulations of this class battery, but owing to the unit magnet of active material in the electrode is not arranged in manufacturing process, thereby the battery of producing can not reach perfect condition, causes easy damage and life-span very short.
Purpose of the present invention is exactly secondary cell and the manufacture method thereof that a kind of charge-discharge performance that adopts straightforward procedure can make secondary cell in process of production of providing for the shortcoming that solves existing secondary cell improves.
Solving technical scheme of the present invention is: a kind of secondary cell, constitute by positive and negative electrode pole plate, barrier film and the electrolyte of having filled active material, and it is characterized in that: described positive and negative electrode pole plate all passes through magnetization orientation.
The manufacture method of the pole plate of secondary cell of the present invention is: earlier with metallic conductor for example: nickel screen/make grid with nickel and stainless porousness thin plate/foaming nickel, on grid, apply again and contain the nickel/copper/iron/zinc/manganese/lithium/titanium/magnesium/cobalt/aluminium/hydrogen bearing alloy/graphite/carbon isoreactivity material that is soaked with adhesive and make substrate, deliver to drying process then, cutting again, installing electrodes lead-in wire are made.It is characterized in that: after the substrate that coating is contained the metal dust that is soaked with active material is orientated by the orientation device earlier, deliver to later process such as drying again.
Because the present invention has adopted above technical scheme, the therefore current direction unanimity of battery, especially its pole plate of producing of secondary cell, charge-discharge performance is good during big electric current, and battery is prolonged useful life.
For further understanding performance of the present invention, feature, now be described in detail as follows in conjunction with preferred embodiment and accompanying drawing thereof.
Accompanying drawing one is first kind of flow sheet of producing the embodiment of secondary cell pole plate of the present invention;
Accompanying drawing two is second kind of flow sheet of producing the embodiment of secondary cell pole plate of the present invention;
Accompanying drawing three is that cell active materials is passed through the material Pareto diagram when being orientated;
Accompanying drawing four is that cell active materials is through the material Pareto diagram after being orientated;
Charge and discharge curve chart when accompanying drawing five is 300mAh of the present invention.
Secondary cell of the present invention is made of the positive and negative electrode pole plate and the electrolyte of having filled active material, and described positive and negative electrode pole plate all passes through magnetization orientation.
Shown in Figure 1 is the manufacturing flow chart of the pole plate of first embodiment of the invention secondary cell, and this is a kind of wet method machinery production flow chart.Make grid 11 with nickel screen or with nickel and stainless porousness thin plate or the nickel that foams earlier, on cylinder 12, grid 11 is directed to process in the container of contain active material 14 by roller bearing 13 again, nickel coating/copper on grid 11/iron/zinc/manganese/lithium/magnesium/cobalt/aluminium/graphite/carbon isoreactivity material 14 is made substrate 15; Again the substrate 15 that contains active material is orientated by orientation device 16, allows water evaporates fall by preparation drying oven 17 then; Make the active material thermal decomposition by preparation firing furnace 18 again; Deliver to sintering in the sintering furnace at last,, and then cutting, add contact conductor and make pole plate again through cooling end 19 cooling.
Wet production battery pole plates of the present invention also can adopt the home built method: earlier active material is made substrate by manually being coated on the grid, the active material on substrate does not have to deliver in the orientation device before the drying and is orientated, and then drying is pressed into pole plate.
Accompanying drawing 2 is flow charts that the present invention makes second kind of manufacture method of secondary cell pole plate, and this is a kind of flow chart of dry production pole plate.Make earlier with nickel screen or with nickel and stainless porousness thin plate or the nickel that foams and make grid 21 on cylinder 22, to contain the metal dust that is soaked with active material again is covered on the grid 21 by automatic hopper 23 inputs, transmit grid and go up contained active material by conveyer belt 24 to orientation device 25, through being pressed into substrate 26 after the orientation device orientation, make pole plate to drier 27 then.
Orientation device of the present invention is a current field or the magnetic field that is made of a permanent magnet.The magnetic flux density of permanent magnet is about 100 Gausses～8000 Gausses; The magnetic flux density of current field is 5000 Gausses～50000 Gausses.The orientation time, under the certain situation of pole plate area width, orientation device magnetic flux density was big more with relevant through the area of the magnetic flux density of out-of-date this orientation device and pole plate in the orientation device, and the orientation time is short more.More than two embodiment be the Ni-MH battery that mobile phone is used, substrate when being 1000 Gausses' orientation device, needed for 30 seconds through magnetic induction intensity approximately in its positive and negative electrode pole plate manufacture process.If only need about 1 second during through 28000 Gausses' orientation device.
Material Pareto diagram when cell active materials is passed through orientation as shown in Figure 3.Since the present invention when making battery pole plates substrate after orientation device orientation, unit magnet in its active material is all by the direction sequence arrangement (as shown in Figure 4) of magnetic field intensity, therefore make its sense of current unanimity behind the battery, discharge and recharge effective, the conversion efficiency height, the charge-discharge performance during 300mAh sees also Fig. 5.Especially during heavy-current discharge, higher by 30% than general battery discharge current, satisfy the requirement of high-power electric appliance tool.
Adopt method of the present invention can make lithium nickel ion battery, lithium manganese ion battery, lithium ion battery, lithium polymer battery and NI-G.Batteries such as ni-mh, zinc-manganese, zinc-nickel, titanium.Battery life of the present invention is long, and after tested, discharging current still is 80% of normal capacity when discharging into 500 times.Can be widely used in occasions such as automatic office equipment, sound equipment image documentation equipment, communication apparatus, electric tool.
