Below in conjunction with the drawings and specific embodiments, the utility model flexible-packed battery and useful technique effect thereof are elaborated, wherein:
Fig. 1 is the structural representation of the utility model flexible-packed battery first execution mode.
Fig. 2 is the structural representation of the utility model flexible-packed battery second execution mode.
Fig. 3 is the side-looking enlarged diagram of the A of circle portion among Fig. 2.
Fig. 4 is the structural representation of the utility model flexible-packed battery the 3rd execution mode.
Fig. 5 is the structural representation of the utility model flexible-packed battery the 4th execution mode.
Embodiment
See also shown in Figure 1ly, be the structural representation of first execution mode of the utility model flexible-packed battery 10, it comprises that packaging film 20 and sealing are contained in the battery 30 in the packaging film 20.
During packing, at first packaging film 20 is launched, battery 30 is put into depressed part; Secondly, packaging film 20 being fitted on the battery 30, aligns respectively in the lug limit 202 of packaging film 20, flanging 206 and encapsulation limit 204, and the positive terminal 302 of battery 30 and negative terminal 304 extend the lug limit 202 of packaging film 20 from the homonymy of battery 30; At last, on lug limit 202, flanging 206 and encapsulation 204 places, limit apply certain pressure and heating, make the polymer fusion on the packaging film 20 and form to be tightly connected.
Different with existing flexible-packed battery is, in first execution mode of the utility model flexible-packed battery 10, encapsulation limit 204 is provided with a Ministry of State Security 208, Ministry of State Security 208 is the weak part of whole packaging film 20, when the gas pressure in the flexible-packed battery 10 surpasses scheduled pressure value, packaging film 20 can split at Ministry of State Security 208 places, thereby discharges and derive gases at high pressure, avoids gases at high pressure directly to spray to the positive terminal 302 and/or the negative terminal 304 of high temperature and ignites.In illustrated embodiment, the thickness direction extension that encapsulates limit 204 is run through in Ministry of State Security 208, and is arranged at the edge on encapsulation limit 204, becomes nick shaped.Be understandable that the shape and size of Ministry of State Security 208 can be determined according to the explosion-proof pressure of reality.
Need to prove, in diagram first execution mode, only show at 204 places, encapsulation limit of flexible-packed battery 10 and offer a Ministry of State Security 208, but, other execution modes according to the utility model flexible-packed battery 10, encapsulation also can be offered a plurality of Ministries of State Security 208 on the limit 204, and is spaced apart between each Ministry of State Security 208.In addition, though in illustrated embodiment, Ministry of State Security 208 is shaped as rectangle, but, other execution modes according to the utility model flexible-packed battery 10, Ministry of State Security 208 also can be arranged to other shapes as required, as circular, trapezoidal or triangle etc., as long as can guarantee that packaging film 20 can break at Ministry of State Security 208 places when the force value of inside battery surpasses predetermined value.
Fig. 2 and second execution mode that Figure 3 shows that the utility model flexible-packed battery 10, different with first execution mode is, in second execution mode of the utility model flexible-packed battery 10,204 extensions of encapsulation limit are not run through in Ministry of State Security 208, but are the non-setting that runs through along the thickness direction on encapsulation limit 204.Please consult shown in Figure 3ly especially, in illustrated embodiment, upper strata packaging film 211 has only been run through in Ministry of State Security 208, does not extend to lower floor's packaging film 210.
Figure 4 shows that the structural representation of the utility model flexible-packed battery 10 the 3rd execution mode, different with first execution mode is, in the 3rd execution mode of the utility model flexible-packed battery 10, Ministry of State Security 208 is arranged at the inside on encapsulation limit 204, can be to run through the through hole that encapsulates limit 204, also can be not run through the groove that encapsulates limit 204.
Figure 5 shows that the structural representation of the 4th execution mode of the utility model flexible-packed battery 10, different with first execution mode is, in the 4th execution mode of the utility model flexible-packed battery 10, the positive terminal 302 of battery 30 and negative terminal 304 are not the homonymies that is positioned at battery 30, but extend from the two opposite sides of packaging film 20 respectively.
The structure of second to the 4th execution mode of the utility model flexible-packed battery 10 is identical with first execution mode with action principle, does not repeat them here.
In conjunction with the detailed description of each top embodiment as can be seen: when the gas pressure in the utility model flexible-packed battery 10 surpasses scheduled pressure value, packaging film 20 can break in the weakest Ministry of State Security 208, with the gases at high pressure in timely release and the guiding battery, avoid inflammable gases at high pressure to contact and ignite with positive terminal 302 and/or negative terminal 304, therefore can effectively prevent battery burning or blast, improve the security performance of flexible-packed battery.
The announcement of book and instruction according to the above description, the utility model those skilled in the art can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the embodiment that discloses and describe above the utility model is not limited to also should fall in the protection range of claim of the present utility model modifications and changes more of the present utility model.In addition, although used some specific terms in this specification, these terms do not constitute any restriction to the utility model just for convenience of description.
