Abstract
The utility model provides a cell shell and a secondary cell that uses the cell shell, of the cell shell comprises a shell body, a cell cover, and an anode and cathode polarized loop eliciting hole is arranged on the shell body, wherein the cell cover is a piston which is hermetically arranged in an inner cavity of the shell body. The cell shell can prevent the explosion caused by the over high air pressure and the dent caused by the over low air pressure inside the cell shell. The secondary cell that uses the cell shell has a lower requirement of the material and thickness of the shell body on the condition that the safety of the cell is guaranteed.
Description
[technical field]
The utility model relates to a kind of battery, especially a kind of secondary cell that prevents the battery case that cell safety hidden danger takes place and use this battery case.
[background technology]
At present, the battery case of existing secondary cell comprises housing and battery cover, housing is a housing with opaque materials such as aluminum hull, box hat and PE-PP composite membranes mainly, sealing is affixed between battery cover and the housing, the both positive and negative polarity electricity sheet and the electrolyte of battery are arranged at the battery case inner chamber, and the both positive and negative polarity lug of battery is electrically connected with both positive and negative polarity electricity sheet respectively.Because secondary cell is when charging process, the housing electrolyte inside can produce gas.When air pressure surpasses the withstand voltage limit of shell material, battery case will be blasted, and when air pressure is lower than the atmospheric pressure in the housing external world, battery case will cave in.The problem that secondary cell at first will be considered when producing is exactly to avoid the blast of battery case or depression to take place.
In addition, because the housing of the battery case of existing secondary cell is a transparent materials, the researcher is unfavorable for the reaction that inside battery takes place is directly observed, the gas volume number that more can't quantitative analysis electrolyte produces particularly can't be described intuitively to the loss of electrolyte in the distribution situation of inside battery electrolyte and the initial charge process, the process that produces gas.
[utility model content]
One of the technical problems to be solved in the utility model provides a kind of battery case that can avoid case fragmentation or depression.
The utility model comprises housing and battery cover, is provided with positive and negative electrode lug fairlead on housing, and wherein, battery cover is a piston, is arranged in the housing inner chamber this piston seal.
On described housing, be provided with the transparent window that to observe its internal piston.This housing can be observed the situation of change of enclosure interior piston intuitively.
On the position corresponding to transparent window on the described housing, be provided with the volume graduation mark.The researcher can observe piston base horizontal tangent correspondence and different volume graduation marks.
Described positive and negative lug fairlead is arranged on housing bottom.
Two of problem to be solved in the utility model just provides a kind of secondary cell that uses the utility model battery case.
Described secondary cell comprises housing and battery cover, is provided with both positive and negative polarity lug fairlead on housing, and wherein, battery cover is a piston, is arranged in the housing inner chamber this piston seal.
On the housing of secondary cell, be provided with the transparent window that to observe its internal piston.This secondary cell can be observed the situation occurred of battery case inner chamber electrolyte and the situation of change of piston very intuitively.
On the position corresponding to transparent window on the housing of secondary cell, be provided with the volume graduation mark.The researcher can observe its base horizontal tangent correspondence intuitively by moving of piston and different volume graduation marks, thus the concrete volume number of the quantitative gas of judging the electrolyte generation.
The space of secondary cell positive and negative electrode lug fairlead is sealed by sealed material.
Compared with prior art, this battery case can prevent to explode because of the battery case air pressure inside is too high or air pressure is crossed low the depression.Use the secondary cell of this battery case guaranteeing under the situation of cell safety, also lower to the shell material and the thickness of shell requirement of its battery case.The transparent window that is provided with on the housing of secondary cell can be observed the situation occurred of battery case inner chamber electrolyte and the situation of change of piston very intuitively, and the volume graduation mark that is provided with on housing can analyze the gas volume number that the housing electrolyte inside produces quantitatively.
[description of drawings]
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model secondary cell.
[embodiment]
Fig. 1 shows the secondary battery construction schematic diagram, and this secondary cell comprises battery case 10, electrolyte 4, electrode slice (8,9) and electrode lug (6,7).This battery case 10 comprises cylindrical housings 2 and piston 1, on housing 2, be provided with the transparent window 11 that to observe its internal piston, on the position corresponding to transparent window 11 on the housing 2, be provided with volume graduation mark 3, be provided with positive pole ear fairlead and negative lug fairlead in housing 2 bottoms, secondary battery positive plate 8 and negative plate 9 are arranged on the inner chamber of housing 2 with being staggered, separate by insulation material 5 between positive plate 8 and the negative plate 9, the positive pole ear 6 of secondary cell and negative lug 7 are electrically connected with the positive plate 8 and the negative plate 9 of battery respectively, positive pole ear 6 is drawn by the positive pole ear fairlead of housing 2 bottoms, negative lug 7 is drawn by the negative lug fairlead of housing 2 bottoms, the space that stays behind the electrode lug fairlead extraction electrode lug (6,7) is by epoxy sealing.Piston 1 is arranged in the inner chamber of housing 2 hermetically, and electrolyte 4 injects battery case 10 internal cavities by injection device, and the liquid level of electrolyte 4 exceeds the upper surface of electrode slice (8,9), is extracted out the air of battery case 10 internal cavities simultaneously by withdrawing device.
Secondary cell in use, piston 1 move can slowly-releasing battery case 10 internal cavities air pressure, avoid case fragmentation or depression to take place, prolong the useful life of battery case; Piston 1 is moved under the effect of the gas that housing 2 electrolyte inside 4 produce, after piston 1 moves to the diverse location of the transparent window 11 on the housing 2, its base horizontal tangent will be corresponding to the different graduation marks of the volume graduation mark 3 on the housing 2, and the researcher just can judge the gas volume number that electrolyte 4 produces intuitively, quantitatively like this.
Use the secondary cell of the utility model battery case to be not limited to above-mentioned execution mode; anyly be familiar with this operator; in not breaking away from spirit and scope of the present utility model; all should drop within the protection range of the present utility model; for example: housing 2 can also be that one side is explained out, the casing that closes of three side sealing at least, and this casing has an inner chamber at least, is provided with transparent window with the corresponding casing of inner chamber; and the position of corresponding transparent window is marked with the volume scale on the casing, and piston 1 adapts with housing 2.
