Problems solved by technology

In this way, since the top of the short pole group is much lower than the opening end of the steel shell, the positive tab will be too long, which will easily cause the positive tab to bend, contact with the steel shell, and cause the battery to short-circuit, burn out, scrap the battery, or even explode.

Embodiment Construction

[0018] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 1 It is a structural sectional view of the battery steel case in an embodiment. The battery steel case is used for accommodating the low electrode group of the battery, including the case 100 . The housing 100 is cylindrical with one end open and has an inner cavity, and the other end is a bottom cover. A holder 110 is disposed inside the housing 100 . The supporting member 110 protrudes from the inner wall of the casing 100 and is used to support the low electrode group of the battery, so as to reduce the distance between the top of the short electrode group and the open end of the steel case, thereby reducing the length of the positive electrode tab.

[0020] In this embodiment, the holding member 110 is 1 to 100 mm away from the bottom cover of the housing 100 to effectively support the short pole group, adju...

Abstract

The invention relates to a battery and a steel shell of the battery. The steel shell of the battery is used for containing a plurality of short pole groups of the battery. The steel shell of the battery comprises a shell body, wherein the shell body is in a cylinder shape with an opened end and is provided with an inner cavity, the other end of the shell body is provided with a bottom cover, the shell body is internally provided with a supporting and holding piece, and the supporting and holding piece bulges out of the inner wall of the shell body for supporting and holding the short pole groups of the battery. As the supporting and holding piece which bulges out of the inner wall is arranged in the middle of the shell body, the short pole groups can be clamped on the supporting and holding piece rather than being contacted with the bottom end of the shell body when the short pole groups are assembled, so that the distance from the top of the supporting and holding piece to the openedend of the steel shell can be shortened, the length of a positive pole lug can be diminished so as to be hard to bend, the short circuit of the battery can be avoided, the battery is prevented from being burnt, the battery can be prevented from being scrapped, the battery is ensured not to be exploded and thus the risks caused by battery explosion are avoided.

Description

【Technical field】 [0001] The invention relates to a battery device, in particular to a battery steel case and a battery. 【Background technique】 [0002] At present, with the expansion of the application of low-capacity Ni-MH batteries, the demand for low-capacity Ni-MH batteries is gradually increasing. [0003] In the process of producing low-capacity Ni-MH batteries, in order to reduce the cost of batteries, it is usually produced by directly assembling short poles into steel shells. In this way, since the top of the short pole group is much lower than the opening end of the steel shell, the positive tab will be too long, which will easily cause the positive tab to bend, contact with the steel shell, and cause the battery to short-circuit, burn out, scrap the battery, or even explode. . 【Content of invention】 [0004] In view of this, it is necessary to provide a battery steel case that prevents the battery from being scrapped. [0005] In addition, it is also necessa...
