Description
Technical field
The invention belongs to field of battery production, specifically a kind of production method of polymer battery.
Background technology
Along with the technical development of lithium ion battery, and lithium ion battery is extensively universal, make more and more to come into one's own to the security performance of lithium ion battery, but common lithium ion aluminum hull and box hat battery core still have the explosion potential of minimum probability, because the shortcoming of itself structure can not be solved, the lighium polymer battery core making security performance higher more and more receives publicity, 18650 lithium batteries are through years development, form standard model more ripe in industry, manufacturing process is comparative maturity also, application also widely, we know that lithium ion battery (as to overcharge in extreme circumstances, high temperature etc.), violent chemical reaction can be there is in inside, produce a large amount of gas, because 18650 batteries use metal shell, there is certain intensity, when air pressure inside reaches certain time, box hat can break blast, there is terrified security incident, and just there are not the problems referred to above in polymer battery, even if when extreme equally, because packaging film intensity is lower, as long as will break when air pressure is slightly high, blast can not be produced, worst situation is burnt exactly, so carry out said polymer battery from safety perspective to be better than 18650 batteries, in conjunction with the extensive versatility of 18650 standard models and the flexibility of assembling, overcome the potential safety hazard of 18650 box hat encapsulation simultaneously, Shi Ge company makes great efforts the problem of research always.
Summary of the invention
The object of the invention is to: the security advantages of lighium polymer battery core is combined with the extensive versatility of 18650 battery cores, produces the production method of the novel battery integrating two kinds of battery advantages.
Technical scheme of the present invention: the production method of polymer battery comprises the following steps:
(1), shaping processing is carried out to raw material cylindrical polymeric battery core;
(2), at cylindrical polymeric battery core anode ear welding positive pole five metals contact;
(3), at cylindrical polymeric battery core negative pole lug welding negative pole five metals contact;
(4) the fill gaps insulation cushion, between positive and negative electrode five metals contact and polymer battery core;
(5), the battery semi-finished product of completing steps 4 are inserted in injection mold, by injection molding machine to the confined space encapsulating between injection molding die and battery semi-finished product;
(6), after cooling device cooling, forming battery is obtained;
(7), to the battery after shaping carry out Shape correction, and apparent size etc. is checked;
(8), battery table surface cover heat-shrink tube carry out pyrocondensation process after Shape correction; Making internal structure is cylindrical polymeric battery core battery.
Injection mold described in described step 5, injection molding machine is low temperature injection mold, injection molding machine
The invention has the beneficial effects as follows:
1. positive and negative electrode five metals contact is first distinguished spot welding (Laser Welding) in the positive and negative lug of the cylindrical polymer battery of correspondence owing to have employed by the present invention, simultaneously to insulating between positive and negative electrode five metals contact and battery core and locating, again by the method for the confined space encapsulating between injection mold and battery semi-finished product, make to form insulating barrier between cylindrical polymer battery core and positive and negative electrode five metals contact, five metals contact is separated completely with battery core body, ensure that battery does not injure the body of cylindrical battery when assembling processing spot welding and being stressed.
2. the present invention is owing to have employed direct the injection forming process, the maximized dimensional space that make use of 18650 battery cores, the battery core effective volume achieving packaged battery maximizes, and effectively improves battery capacity volume ratio, effectively ensure that the outward appearance of battery and the consistency of size.
3. the present invention has packaging technology simply, with low cost, the advantage that production efficiency is high, and for production clamp tool, the less demanding advantage of cell package plant equipment.
4. the present invention produces the cylinder steel shell lithium battery of most digital class 18650 dimensions on the replaceable market of product, can replace use by slitless connection, can use, being suitable for widely without the need to revising product structure.
5. the present invention is owing to adopting cylindrical polymer battery encapsulation, completely avoid the problem that 18650 box hat batteries exist hidden peril of explosion, is particularly suitable for toy for children, in the handheld device that the security requirements such as camera are high.
Embodiment
A kind of cylindrical polymer battery low-pressure injection molding method, comprises the steps:
(1) cylindrical polymeric battery core is carried out shaping processing, make its interface rules;
(2) cylindrical polymeric battery core anode ear is welded in the five metals contact of blocking a shot similar with 18650 anodes, by five metals contact can realize battery core externally discharge and realize battery flexible assembling welding;
(3) by cylindrical polymeric battery core negative pole lug welding in the five metals contact similar with 18650 battery cathode contacts, by five metals contact can realize battery core externally discharge and realize battery flexible assembling welding;
(4) the fill gaps insulation cushion between positive and negative electrode five metals contact and battery core, insulation cushion double-sided belt glue, plays five metals contact and battery core keeps certain space, the effect directly do not contacted; Play the effect that five metals contact is positioned simultaneously.
(5) semi-finished product battery core shaping completed is inserted in special low temperature injection mold, by low temperature injection molding machine to the confined space encapsulating between injection molding die and battery semi-finished product;
(6) after cooling device cooling, forming battery is obtained;
(7) Shape correction is carried out to the battery after shaping, and apparent size etc. is checked;
(8) overlap at semi-finished product cell pool surface the heat-shrink tube that heat-shrinkable thickness is 0.1mm, battery and common 18650 batteries indistinction after pyrocondensation, but internal structure is cylindrical polymer battery, greatly improves the fail safe of 18650 cylindrical batteries.
