Abstract
The invention discloses a method for processing lugs of a polymer soft-packaging lithium battery. The polymer soft-packaging lithium battery comprises a positive plate, a negative plate and a diagram arranged between the positive plate and the negative plate, wherein the positive plate and the negative plate contain current collectors and electrode substances. The processing method comprises the following steps of: fully mixing active substances, a conductive agent and a binding agent in proportion and then preparing mixed size, coating the mixed size onto the current collectors in a roll coating way, a blade coating way or a spray coating way, the positive plate, the negative plate and the diagram are wound into a battery cell fixed by fixed adhesive tapes, placing the battery bell welded with the lugs into a packaging case, and carrying out encapsulating, vacuum drying, filling, sealing, formation, capacity grading and inspection to obtain the polymer soft-packaging lithium battery. The method is characterized in that a copper sheet is directly welded on the positive lug in an ultrasonic welding way before the positive plate, the diagram and the negative plate are wound into the battery cell or the copper sheet is welded onto the positive lug in the ultrasonic welding way during overlying after the positive plate, the diagram and the negative plate are wound into the battery cell. By adopting the method disclosed by the invention, investment on lug conversion equipment and human input are reduced for enterprises, product quality is improved, dependence on proficiency of personnel is reduced, and the dilemma that the current enterprise is difficult to recruit workers can be alleviated in a certain degree.
Description
Technical field
The present invention relates to the polyalcohol flexible packing lithium battery, belong to field of batteries, particularly relate to a kind of lug processing method of polyalcohol flexible packing battery.
Background technology
At present, the lug of polyalcohol flexible packing lithium battery conversion mainly contains two kinds of technologies: ultrasonic wave changes nickel technology and laser welding process, and two kinds of technologies are all on the finished product battery welds, in case scrap then this battery is scrapped.
Ultrasonic welding process is will cut through the polyalcohol flexible packing lithium battery anode ear that operations such as film-making, coiling, encapsulation are made earlier, stay 3.5-4.0mm, the nickel strap that will cut in advance carries out ultra-sonic welded with that part of anode ear that stays then, weld the back and pruned corner angle, beating electronic pastes in the contact position of pad and battery then fixes, re-use U.S. line gummed paper and fix, this method had 5 steps, needed the labour to be no less than 6; The fragility more that simultaneously anodal aluminium pole ears becomes through ultra-sonic welded, weld very easily ruptures; Beat in addition in the electronic pastes process, it is dirty that glue causes battery surface to be stained with easily; When using U.S. line gummed paper fixedly, because paste position is narrow and small only about 4.5mm, workman's task difficulty height requires very high to workman's proficiency.
Laser welding process is earlier will be through film-making, reel, the polyalcohol flexible packing lithium battery anode ear that operations such as encapsulation are made is cut, stay 3.5-4.0mm, the nickel strap that will cut in advance carries out laser welding with that part of anode ear that stays then, re-using U.S. line gummed paper fixes, this method is to the equipment requirements height, the disposable input of laser welding apparatus is bigger, and daily use consumes also expensive, when using U.S. line gummed paper fixedly simultaneously, also because paste position is narrow and small only about 4.5mm, workman's task difficulty height is very high to workman's proficiency requirement, bigger to employee's harmfulness in the laser welding apparatus use in addition.
Summary of the invention
The technical problem to be solved in the present invention is, defective at present polyalcohol flexible packing lithium battery pole ear conversion process, a kind of lug processing method of polyalcohol flexible packing lithium battery is provided, the lug conversion that this method is carried out reduces business equipment input, human input, improve the quality of products, minimizing is to a certain degree alleviated the difficult predicament of present enterprise's recruitment to the dependence of employee's proficiency.
The technical solution adopted for the present invention to solve the technical problems is: the polyalcohol flexible packing lithium battery comprises positive plate, negative plate and the barrier film that places therebetween, just, negative plate comprises collector and electrode substance, pole piece is by with active material and conductive agent, binding agent is made mixed slurry after fully mixing in proportion, pass through roller coat, blade coating or spray coating are to collector, positive plate, barrier film and negative plate are wound into electric core and fix with fixation adhesive tape, the electric core of the lug of burn-oning is put into pack case, encapsulate, vacuumize, fluid injection, seal, change into, partial volume, check, obtain battery, it is characterized in that: positive plate, barrier film and negative plate are wound into directly copper sheet to be ultrasonically welded within before the electric core on the positive pole ear and reel; When perhaps positive plate, barrier film and negative plate are wound into behind the electric core stack copper sheet is ultrasonically welded within on the positive pole ear.
Lug processing method of the present invention is directly to weld on lug, scrap even have by chance in ultra-sonic welded, but the enterprises' loss minimizing is a lot, because an anode ear is worth about 1 yuan, electric core is worth about 35 yuan about 5Ah.
Embodiment
Describe in detail below in conjunction with specific embodiment.
Embodiment 1: the polyalcohol flexible packing lithium battery comprises positive plate, negative plate and the barrier film that places therebetween, just, negative plate comprises collector and electrode substance, pole piece is by with active material and conductive agent, binding agent is made mixed slurry after fully mixing in proportion, pass through roller coat, blade coating or spray coating are to collector, directly copper sheet is ultrasonically welded within on the positive pole ear, positive plate, barrier film and negative plate are wound into electric core again and fix with fixation adhesive tape, the electric core of lug of burn-oning is put into pack case, encapsulate, vacuumize, fluid injection, seal, change into, partial volume, check obtains battery.
Embodiment 2: the polyalcohol flexible packing lithium battery comprises positive plate, negative plate and the barrier film that places therebetween, just, negative plate comprises collector and electrode substance, pole piece is by with active material and conductive agent, binding agent is made mixed slurry after fully mixing in proportion, pass through roller coat, blade coating or spray coating are to collector, positive plate, barrier film and negative plate are wound into electric core and fix with fixation adhesive tape, when being wound into behind the electric core stack copper sheet is ultrasonically welded within on the positive pole ear, the electric core of lug of burn-oning is put into pack case, encapsulate, vacuumize, fluid injection, seal, change into, partial volume, check obtains battery.
With the 9068130-5Ah model is comparison other, 10,000 electric cores of the daily output are calculated, and the comparative example 2 of embodiments of the invention 1,2 and the comparative example 1 of former ultra-sonic welded technology, former laser welding process is compared, and specifically sees Table one, an anode ear is worth about 1 yuan, and electric core is worth about 35 yuan about 5Ah.
Table 1
Remarks: mean values in the production process that above data are all got.
As shown in Table 1, directly lug is changed before making battery owing to adopt, reduce business equipment input, human input, improve the quality of products, minimizing is to a certain degree alleviated the difficult predicament of present enterprise's recruitment to the dependence of employee's proficiency, has reduced the internal resistance that anode ear causes because of welding simultaneously, more help discharging and recharging of battery, reduce battery self from power consumption.
