Description

A kind of high capacity low cost mangaic acid lithium ion battery cell
Technical field
The utility model relates to field of lithium ion battery, specifically a kind of high capacity low cost mangaic acid lithium ion battery cell.
Background technology
Along with the application of LiMn2O4 ion battery is more and more extensive, the battery requirements amount of big current, high power capacity increases day by day.Tradition LiMn2O4 ion battery is all be made up of single mangaic acid lithium ion battery cell, for high-capacity battery, because thickness is large, wayward elasticity during electric core winding, winding difficulty is large, and after battery core assembling, because battery core is thick, turning is large, and the useful space of battery utilizes on the low side; In addition, the thick battery core of single high power capacity, in follow-up charge and discharge process, easily produces accumulative deformation, thus causes battery appearance deformation, uneven thickness etc.; Adopt the mode of lamination, can solve the problem of above-mentioned thick battery core, but lamination rolling step is loaded down with trivial details, be unfavorable for large batch of production, and equipment requirement is high, cost is large.
Utility model content
The purpose of this utility model is to provide a kind of high capacity low cost mangaic acid lithium ion battery cell, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of high capacity low cost mangaic acid lithium ion battery cell, comprise the planar unit mangaic acid lithium ion battery cell that three tile heights are identical, width is identical, the stacked setting of described three pieces of monomer mangaic acid lithium ion battery cells, described every block monomer mangaic acid lithium ion battery cell is formed by barrier film, positive plate and anode ear thereof, negative plate and negative electrode lug thereof, described barrier film is between positive plate and negative plate, described positive plate, negative plate and barrier film successively reel to same direction, described anode ear and positive plate electrical contact, described negative electrode lug and negative plate electrical contact.
As further program of the utility model: the anode ear of described three pieces of monomer mangaic acid lithium ion battery cells is connected together by the series welding of positive pole bonding pad and the last item is drawn by an aluminium nickel strap.
As the utility model further scheme: the negative electrode lug of described three pieces of monomer mangaic acid lithium ion battery cells is connected together by the series welding of negative pole bonding pad and the last item is drawn by an aluminium nickel strap.
Compared with prior art, the beneficial effects of the utility model are: the single lithium battery battery core little by some thickness is formed, and it is little that the battery produced adds up deformation, flat appearance; Because single lithium battery battery core thickness is little, its winding difficulty is little, and compact conformation is easy to make, reduces cost; And owing to being composed in series by multiple monomer battery core, because this reducing the risk of short circuit, improve fail safe, being conducive to the LiMn2O4 ion battery producing high power capacity, big current.
Accompanying drawing explanation
Fig. 1 is the structural representation of high capacity low cost mangaic acid lithium ion battery cell.
Fig. 2 is the structural representation of the monomer mangaic acid lithium ion battery cell of high capacity low cost mangaic acid lithium ion battery cell.
In figure: 1-monomer mangaic acid lithium ion battery cell, 2-aluminium nickel strap, 3-aluminium nickel strap, 4-positive pole bonding pad, 5-negative pole bonding pad, 11-anode ear, 12-negative electrode lug, 13-positive plate, 14-barrier film, 15-negative plate.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-2, a kind of high capacity low cost mangaic acid lithium ion battery cell, comprise three tile heights identical, the planar unit mangaic acid lithium ion battery cell 1 that width is identical, the stacked setting of described three pieces of monomer mangaic acid lithium ion battery cells 1, the anode ear 11 of described three pieces of monomer mangaic acid lithium ion battery cells 1 is connected together by positive pole bonding pad 4 series welding and the last item is drawn by an aluminium nickel strap 2, the negative electrode lug 12 of described three pieces of monomer mangaic acid lithium ion battery cells 1 is connected together by negative pole bonding pad 5 series welding and the last item is drawn by an aluminium nickel strap 3, described every block monomer mangaic acid lithium ion battery cell 1 is formed by barrier film 14, positive plate 13 and anode ear 11 thereof, negative plate 15 and negative electrode lug 12 thereof, described barrier film 14 is between positive plate 13 and negative plate 15, described positive plate 13, negative plate 15 and barrier film 14 successively reel to same direction, described anode ear 11 and positive plate 13 electrical contact, described negative electrode lug 12 and negative plate 15 electrical contact.
Operation principle of the present utility model is: the single lithium battery battery core little by some thickness is formed, and it is little that the battery produced adds up deformation, flat appearance; Because single lithium battery battery core thickness is little, its winding difficulty is little, and compact conformation is easy to make, reduces cost; And owing to being composed in series by multiple monomer battery core, because this reducing the risk of short circuit, improve fail safe, being conducive to the LiMn2O4 ion battery producing high power capacity, big current.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned execution mode, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
