The existing lithium ion battery that is built in the panel computer is a monoblock or several macrocells that are connected together or battery pack, and relatively flexible screen belongs to the steel body structure, can not be crooked, therefore can't satisfy actual operation requirements.Although take the mode of a plurality of battery series-parallel connections can solve aforementioned technical problem, but, series-parallel package assembly between a plurality of batteries needs numerous peripheral device structure, causes the waste of space structure, causes energy content of battery density not satisfy the actual demand of electrical appliance.
In view of this, but necessaryly provide a kind of bending lithium ion battery, to solve the problems of the technologies described above.
The utility model content
The purpose of this utility model is: provide a kind of simple in structure, convenient for production, but and can overcome the bending lithium ion battery that has battery defect now.
In order to realize the foregoing invention purpose, but the utility model provides a kind of bending lithium ion battery, it comprises encapsulation paper tinsel, several battery cores, flexible connecting line, and the electrolyte of can in the encapsulation paper tinsel, be provided with several grooves in the encapsulation paper tinsel, contain battery core in the groove, flexible connecting line be connected to each battery core positive and negative lug and to encapsulation just always drawing outside the paper tinsel, total negative pole end.
But as a kind of improvement of the utility model bending lithium ion battery, the battery core in the described encapsulation paper tinsel is connected and/or is connected in parallel.
But as a kind of improvement of the utility model bending lithium ion battery, the groove that is provided with in the described encapsulation paper tinsel is matrix and arranges.
But a kind of improvement as the utility model bending lithium ion battery is provided with the interval between the described groove, and groove is arranged by horizontal and vertical order.
But as a kind of improvement of the utility model bending lithium ion battery, described battery core is naked battery core, and being reeled by yin, yang pole piece and barrier film forms, and described positive and negative lug is arranged on homonymy or the heteropleural of battery core.
But as a kind of improvement of the utility model bending lithium ion battery, independently do not shut between the described naked battery core, described electrolyte is free between the naked battery core.
But as a kind of improvement of the utility model bending lithium ion battery, described encapsulation paper tinsel is to take normal process encapsulation, the interval region between the groove to take the interval encapsulation and form the periphery of package foil.
Compared with prior art, but the utility model bending lithium ion battery because self design feature can realize that it carries out bending to a certain extent, even can doubling, to adapt to the specific demand of the electronic products such as flexible screen.
Description of drawings
Below in conjunction with the drawings and specific embodiments, but the utility model bending lithium ion battery and its useful technique effect are elaborated, wherein:
But Fig. 1 is the structural representation of the utility model bending lithium ion battery.
Fig. 2 is but that the utility model bending lithium ion battery is towards the schematic diagram of a direction bending.
Embodiment
Goal of the invention of the present utility model, technical scheme and useful technique effect are more clear to be understood in order to make, and below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.Should be understood that the embodiment of describing in this specification only is in order to explain the utility model, is not in order to limit the utility model.
See also shown in Fig. 1,2, but the utility model provides a kind of bending lithium ion battery 100, it comprises encapsulation aluminium foil 10, several battery cores (1-1,1-2,1-3,1-15), flexible connecting line 20, and the electrolyte (not shown) of can in encapsulation aluminium foil 10.Encapsulation is provided with several grooves (not shown) in the aluminium foil 10, and correspondence contains battery core in the groove, flexible connecting line 20 be connected to the positive and negative lug of each battery core and outside the encapsulation aluminium foil, just always drawing, total negative pole end (30,40).
Below, be grooves that matrix arranges as example to offer several at encapsulation aluminium foil 10, but introduce the manufacturing process of the utility model bending lithium ion battery, wherein, matrix is chosen as the 5*3 matrix, i.e. 5 row, 3 row.
At first, go out 5 row, 3 row by certain specification at the encapsulation aluminium foil and be the groove that matrix is arranged, again naked battery core is put into groove by the diagramatic way correspondence, in the process of placing, the positive and negative lug interval of battery core is put, face mutually the anode ear of battery core to guarantee that negative electrode lug is aimed at.
Subsequently, flexible connecting line 20 is welded on the positive and negative lug of each naked battery core by order illustrated.Specifically, "-" of naked battery core 1-1 is connected with flexible connecting line with naked battery core 1-2 "+", "-" of naked battery core 1-2 and "+" of naked battery core 1-3 use flexible connecting line, are linked in sequence down successively, and the trend graph of flexible connecting line 20 is shown in dotted line.
At last, the above-mentioned aluminium foil of having placed battery core and having connected flexible connecting line 20 is encapsulated by normal mode, and guarantee that the interval region between battery core and the battery core encapsulates by the mode of interval encapsulation, forms seal district 50.In encapsulation process, guarantee independently not shut between each battery core, so that the electrolyte of can in the encapsulation aluminium foil is free between the naked battery core.
