Description
Technical field
The present invention relates to a kind of square polymer battery, and in particular to a kind of square polymer battery length direction series connection
Method.
Background technology
Lithium ion battery is a kind of battery of novel high-performance of high speed development nearly ten years, its small volume, it is in light weight,
Energy density is big, is widely used in the electronic apparatus such as mobile communication, video camera, notebook computer, and progressively to it is electronic from
Driving, electric automobile, global position system and national defence are expanded, and lithium ion battery is the most promising and market space
High-energy battery of new generation.
Conventional square polymer battery is one kind of lithium ion battery, and positive and negative lug thereon is in same one end of battery, together
When in the presence of a battery closedtop position, the shortcomings that substantially thinner than battery body, the series connection of this battery length direction be present in this position
Assembling of getting up is typically all that could be completed by connection mode, but series-connected cell is more, it is necessary to which the line of connection is more, and operation is non-
It is often cumbersome, production is not utilized, and efficiency substantially reduces.
The content of the invention
The present invention is directed to the deficiency of above-mentioned technology, there is provided a kind of method of square polymer battery length direction series connection,
This method does not need loaded down with trivial details line to operate, and battery 2 is easy to operate when going here and there and going here and there more, quickly, attractive in appearance, and passes through such a method
Improve the energy density of unit volume battery.
The present invention is achieved like this, a kind of method of square polymer battery length direction series connection, it is characterised in that
Method and step is as follows：
（1）When battery makes winding process, allowing a lug, another lug is placed down upward, two lugs point
Not on the both sides of core body, while two lugs are not placed in the centre of core width, respectively in the both sides of core, carry out electricity
The sealing side flanging of pond two；
（2）Single battery final finished folds up battery closedtop position, and then battery top and bottom are coffee-like
High temperature gummed tape is fixed, the side bag high tempreture tape of battery two；
（3）Battery plus-negative plate is end to end, the positive pole of a upper battery（Or negative pole）With the negative pole of next battery（Or just
Pole）Direct spot welding or the connection of upper tin, it is not necessary to loaded down with trivial details line operation.
（1）In machine winding process, allow battery a lug upward, another lug is placed down, so makes volume
Around core lug out respectively in the both sides of core；
（2）Machine rolls around when be wound using flat core, pole piece is inserted into bottom when inserted sheet, lug edge with
It is concordant to roll up pin inside edge, negative pole inserts positive pole after winding one layer, makes two lugs not placed in the middle, respectively in the both sides of the edge of core；
（3）Shell is rushed to be designed to, by there are 2 top margins, four side structures of 2 sides, use the packaging technology of 2 films altogether；
（4）Core is put into the aluminum plastic film for having cut top margin, 2 closedtops is carried out with simple closedtop machine, then uses side
Seal machine and carry out side seal；
（5）First 2 side sealings are folded up after single battery partial volume, while 2 closedtop positions of battery are also folded up, so
Battery top and bottom are fixed with coffee-like high temperature gummed tape afterwards, the side bag high tempreture tape of battery two；
（6）During battery assembled in series, upset battery makes battery plus-negative plate end to end, the positive pole of a upper battery（It is or negative
Pole）With the negative pole of next battery（Or positive pole）Direct spot welding or the connection of upper tin, do not need so loaded down with trivial details line to operate.
（7）The excessively blue thermoplastic film of the final appearance of series-connected cell finished product.
It is an advantage of the invention that：（1）, can one anode of the above because battery pole ear is respectively on the two sides of battery body
（Or negative pole）With next GND（Or positive pole）Direct spot welding or the connection of upper tin, it is not necessary to loaded down with trivial details line operation, electricity
Pond 2 go here and there and go here and there more it is easy to operate, it is quickly, attractive in appearance；（2）Because two closedtop positions of battery are folded up, thus it is not present
One obvious closedtop position thinner than battery body, improve the energy density of unit volume battery；（3）For being gathered using square
The digital equipment of compound series connection, the final positive pole pole of this assembled in series method battery of use of device power supply (DPS) both positive and negative polarity heterodoxy is not required to
Line is wanted, battery plus-negative plate directly can be welded in above the power positive cathode of digital equipment, human-saving and electric wire cost.
