At present, the function of removable electronic products such as mobile phone, panel computer, notebook computer is more and more abundanter, size is done more and more thinlyyer, also requires the power work time to prolong as far as possible when constantly satisfying higher portability requirement, and this requirement to the energy density of power supply is also more and more higher.Along with further developing of facilitation, the screen of some electronic product such as panel computer can be realized bending fold, therefore not only require built-in power supply to have high energy density, also will meet corresponding structure design simultaneously, can under the situation of screen-bending, normally use.
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 flexible relatively screen belongs to the steel body structure, can not be crooked, therefore can't satisfy actual instructions for use.Though take the series-parallel mode of a plurality of batteries 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.
Summary of the invention
The objective of the invention is to: 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 invention provides a kind of bending lithium ion battery, it comprises encapsulation paper tinsel, several electric cores, line is flexible coupling, and the electrolyte of can in the encapsulation paper tinsel, be provided with several grooves in the encapsulation paper tinsel, contain electric core in the groove, the line that is flexible coupling be connected to each electric 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 present invention's bending lithium ion battery, the electric core in the described encapsulation paper tinsel is connected and/or is connected in parallel.
But as a kind of improvement of the present invention's bending lithium ion battery, the groove that is provided with in the described encapsulation paper tinsel is arranged.
But as a kind of improvement of the present invention's bending lithium ion battery, be provided with between the described groove at interval, groove is arranged by horizontal and vertical order.
But as a kind of improvement of the present invention's bending lithium ion battery, described electric core is naked electric core, and being reeled by yin, yang pole piece and barrier film forms, and described positive and negative lug is arranged on the homonymy or the heteropleural of electric core.
But as a kind of improvement of the present invention's bending lithium ion battery, independently do not shut between the described naked electric core, described electrolyte is free between the naked electric core.
But as a kind of improvement of the present invention's bending lithium ion battery, described encapsulation paper tinsel is to take normal process encapsulation, the interval region between the groove to take encapsulation at interval and form the periphery of package foil.
Compared with prior art, but the present invention's 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 electronic products such as flexible screen.
Description of drawings
Below in conjunction with the drawings and specific embodiments, but the present invention's bending lithium ion battery and its useful technique effect are elaborated, wherein:
But Fig. 1 is the structural representation of the present invention's bending lithium ion battery.
But Fig. 2 is the schematic diagram of the present invention's bending lithium ion battery towards a direction bending.
Embodiment
Goal of the invention of the present invention, 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 present invention is further elaborated.Should be understood that the embodiment of describing in this specification only is in order to explain the present invention, is not in order to limit the present invention.
See also shown in Fig. 1,2, but the invention provides a kind of bending lithium ion battery 100, it comprises encapsulation aluminium foil 10, several electric cores (1-1,1-2,1-3,1-15), the line 20 that is flexible coupling, 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 electric core in the groove, the line 20 that is flexible coupling be connected to the positive and negative lug of each electric core and outside the encapsulation aluminium foil, just always drawing, total negative pole end (30,40).
Below, be example on encapsulation aluminium foil 10, to offer several grooves that are arranged, but introduce the manufacturing process of the present invention's bending lithium ion battery that wherein, matrix is chosen as the 5*3 matrix, i.e. 5 row, 3 row.
At first, on the encapsulation aluminium foil, go out the groove that 5 row, 3 row are arranged by certain specification, again naked electric core is put into groove by the diagramatic way correspondence, in the process of placing, the positive and negative lug of electric core is put at interval, aim at the anode ear that faces electric core mutually to guarantee negative electrode lug.
Subsequently, the line 20 that will be flexible coupling is welded on the positive and negative lug of each naked electric core by order illustrated.Specifically, "-" of naked electric core 1-1 is connected with the line that is flexible coupling with naked electric core 1-2 "+", "-" of naked electric core 1-2 and naked electric core 1-3 "+" is linked in sequence down successively with the line that is flexible coupling, and the trend graph of the line 20 that is flexible coupling is shown in dotted line.
At last, the above-mentioned aluminium foil of having placed electric core and having connected the line 20 that is flexible coupling is encapsulated by normal mode, and guarantee that the interval region between electric core and the electric core encapsulates by the mode of encapsulation at interval, forms seal district 50.In encapsulation process, guarantee independently not shut between each electric core, so that the electrolyte of can in the encapsulation aluminium foil is free between the naked electric core.
Need to prove that though in the illustrated embodiment, each electric core is cascaded,, in actual production process, also can carry out parallel connection to the requirement of cell voltage and capacity, perhaps the mode of string and series-parallel connection according to the client.In addition, electric core is naked electric core, and being reeled by yin, yang pole piece and barrier film forms, and positive and negative lug can be arranged on the homonymy or the heteropleural of electric core.
With respect to prior art, but the present invention's bending lithium ion battery has the following advantages: owing to being provided with between the groove that is arranged at interval, cooperate the line bendable folding endurance flexibly that is flexible coupling again, therefore, packaged lithium ion battery can carry out bending to a certain extent, even can realize being expert at and row between, fold between row and the row.Be to be assembled in after battery completes on the panel computer that has flexible screen, it is crooked or folding on X and the Y direction to coexist with screen one.
According to above-mentioned principle, the present invention can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the present invention is not limited to also should fall in the protection range of claim of the present invention modifications and changes more of the present invention.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the present invention just for convenience of description.
