Embodiment
The utility model is provided for the thick steel shell of cylindrical shape difference of battery, and it can increase battery cylindrical shape box hat internal diameter under not influence of battery seal situation, thereby improves the loading of battery plus-negative plate active material, makes the discharge capacity of battery improve about 5%.Its feature is: battery cylindrical shape differential thickness steel casing adopts steel band punching out drawing and forming, the cylindrical shell position thickness of box hat is than other position thin 28% after the cylindrical shape punching out, can be reached for 0.18 ± 0.02mm, just cylindrical shell position thickness is than the thin thickness of steel band, and being of uniform thickness of anodal and negative pole and steel band, the size of straight shape connecting portion housing 6 is than the now widely used battery cylindrical shape plain edition box hat 0.6～1.3mm that extends.
The thick steel shell of cylindrical shape difference of the present utility model can be used for No. 1 battery, No. 2 batteries, No. 5 batteries, No. 7 batteries.
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.The experimental technique of unreceipted actual conditions in the following example, usually according to normal condition, or the condition of advising according to manufacturer.
Embodiment:
Cylindrical shell body housing 1 described in the utility model is meant the housing parts between anodal partial shell 3 and negative pole junction housing 4.
Referring to Fig. 1, battery container, it comprises the cylindrical shell body housing 1 that holds cell active materials part 2, be positioned at the anodal partial shell 3 of cylindrical shell body housing 1 upper end, be positioned at the negative pole junction housing 4 of described cylindrical shell body housing 1 lower end, negative pole junction housing 4 comprises convex connecting portion housing 5 and straight shape connecting portion housing 6, and the thickness of anodal partial shell 3 and negative pole junction housing 4 adopts this area routine techniques, for example adopt the box hat of steel band punching out, thickness of strips is about 0.25mm.The cross section of cylindrical shell of the present utility model can be a cylindrical shape, also can be oval or square.
In the utility model, the thickness after cylindrical shell body housing 1 punching out between anodal partial shell 3 and the negative pole junction housing 4 is 0.18mm (can between 0.18 ± 0.02mm).Compare with the battery of prior art, because the cylindrical shell thickness at this position is generally 0.25mm in the battery of prior art, therefore dischargeable capacity increases about 3～5% in the housing of the present utility model, thereby improves the loading of battery plus-negative plate active material, reduces the consumption of steel band simultaneously.
Anodal partial shell 3 is the same with original thickness of strips after the punching out, guarantees intensity herein, solves the yielding problem of battery production process, referring to Fig. 3 A and 3B.
Negative pole junction housing 4 was the same with original thickness of strips after the punching out, had guaranteed the intensity of sealing behind the battery crimping, referring to Fig. 1.
