Abstract
The utility model discloses a curved surface polymer lithium ion battery which comprises a battery shell body, a laminated cell and electrolyte, the current collector of the laminated cell extends out of the shell body to form the anode and cathode of the battery, the shell body is made of aluminum plastic composite film, and the aluminum plastic composite film and the laminated cell wrapped by the composite film are bent to form a curved surface with certain curvature radius. The curved surface polymer lithium ion battery can be jointed with spherical surface or arc surface and satisfies the requirements of electrical appliances on battery exterior.
Description
Technical field
The utility model relates to battery, relates in particular to a kind of curved surface shaped polymer Li-ion battery.
Background technology
Along with the development of modernized society, polymer Li-ion battery being applied on the various products more and more widely is as mobile phone, computer, digital camera, PDA or the like.Because the variation of electrical appliance is also more and more personalized to the external form requirement of battery product.Except traditional square, cylindrical, some users wish that the external form of battery also can follow one's bent.The external form great majority of current battery are circle, rectangle, trapezoidal, and the external form style is few, does not have the curved surface shaped battery.
The utility model content
The purpose of this utility model is to solve above-mentioned problems of the prior art, proposes a kind of curved surface shaped polymer Li-ion battery.
The technical solution adopted in the utility model is a kind of curved surface shaped polymer Li-ion battery of design, comprise: battery container, be sealed in lamination electricity core and electrolyte in the battery container, the collector of described lamination electricity core stretches out the both positive and negative polarity that housing forms battery, wherein: described housing adopts aluminum-plastic composite membrane, and the lamination electricity chip bending of this aluminum-plastic composite membrane and Qi Nei parcel becomes the curved surface of certain curvature radius.
In an embodiment of the present utility model, the length of described positive plate and described negative plate and width are 100 millimeters, described lamination electricity core comprise five positive plates, with positive plate interlock six stacked negative plates and be clipped in positive plate and negative plate between diaphragm paper, described positive plate is provided with the weld zone that is connected described collector with negative plate.The collector that described lamination electricity core both positive and negative polarity is drawn adopts aluminum strip and nickel bar respectively.
Compared with prior art, the curved surface shaped polymer Li-ion battery of the utility model design can adopt different curvature, and smooth certain spherome surface or the arc of fitting in satisfies the demand of various electrical appliances to the battery external form.
Description of drawings
Below in conjunction with drawings and Examples the utility model is done detailed explanation, wherein:
Fig. 1 is the schematic diagram of the utility model positive and negative plate;
Fig. 2 is the schematic diagram of the utility model lamination electricity core;
Fig. 3 is a schematic perspective view of the present utility model.
Embodiment
Fig. 1 is the positive plate schematic diagram in preferred embodiment of the utility model, and positive plate is provided with the weld zone 1 that connects collector.Negative plate is identical with the positive plate profile, weld zone 1 position opposite of collector.The length of positive plate, negative plate and width are 100 millimeters.Positive plate has 5 in the present embodiment, and negative plate has 6, and they are staggered stacked, accompany diaphragm paper between positive plate and negative plate, so is combined into lamination electricity core.The profile of lamination electricity core is please referring to Fig. 2, and the lamination electricity core after the combination has positive and negative two weld zones 1, and collector is welded into an integral body separately with positive plate and negative plate, and the electric current on the lamination electricity core is drawn outside the housing.The utility model middle shell adopts aluminum-plastic composite membrane, and positive and negative electrode is drawn collector and is respectively aluminum strip, nickel bar.
The utility model adds man-hour, and the polymer Li-ion battery positive/negative plate is cut into 100 * 100mm small pieces respectively, reserves the collector weld zone on the sheet, as shown in Figure 1; Then, with 5 positive plates and 6 negative plates and diaphragm paper combination, connect collector 1, promptly be combined as lamination electricity core, as shown in Figure 2 by supersonic welding in the lamination mode; The aluminum-plastic composite membrane shell of again lamination electricity core being packed into, mode with heat-sealing after the vacuumize seals, in the end inject electrolyte before one sealing process during this time, then by special hot pressing, the polymerization technique of colding pressing, make electric core be shaped to curved face type, change at last, bleed, shaping, finally make the battery finished product, as shown in Figure 3.
The utility model can adopt different curvature bendings, so that fit with different sphere or cambered surface.The battery parameter of present embodiment is: average working voltage 3.7V, and capacity 416mAh, internal resistance 84.2m Ω, 100 all circulation volume conservation rates are 98.17%.
Better embodiment of the present utility model has more than been described; but the those of skill in the art in the present technique field are to be understood that; these only illustrate; those skilled in the art can make numerous variations or variation to these execution modes, and these changes and variation should fall within the scope of the utility model protection.
