Abstract
The utility model discloses a primary battery and secondary battery head suitable for aluminum-plastic encapsulation. The primary battery and secondary battery head is realized through the following technical proposal: the head is composed of an upper head and a lower head; one of the upper head and the lower head is elliptical or round, the other one of the upper head and the lower head is a plane, a semi-elliptical shape or a hemicycle. With the primary battery and secondary battery head structure, encapsulation is conducted from the vertex of two heads to two sides to realize line-plane encapsulation, thereby effectively discharging bubbles produced during encapsulation and liquid bubbles formed by sprayed electrolyte during encapsulation, preventing the non-encapsulation problem caused by the uneven plane head, ensuring good encapsulation effect, effectively ensuring the required encapsulation width, and effectively preventing air blowing and electrolyte leakage of batteries.
Description
Technical field
The utility model relates to polymer/soft-package battery field, more particularly, relate to a kind of be suitable for the plastic-aluminum envelope once with the end socket of secondary cell.
Background technology
At present, along with people to the approval of the various performances of polymer/soft-package battery and certainly, polymer/flexible-packed battery has obtained extensive utilization in growing field, as bluetooth earphone, MP3, MP4, mobile phone, GPS, mobile DVD, even apple is applying to them on the notebook computer in recent years, because characteristics such as light weight, fail safe are good, energy density height have obtained great success.But, for this battery by plastic-aluminum encapsulation bag encapsulated moulding, encapsulation technology is very crucial, air-blowing and leakage are difficult problems that is perplexing many batteries producer always, because the bad example of battery air-blowing and leakage that causes of encapsulation is too numerous to mention, even cause a lot of major accidents that battery is recalled that rise.The analysis showed that, crossing encapsulation when short circuit when shell shake, closedtop encapsulation, side seal except that plastic-aluminum encapsulation bag during towards shell causes battery air-blowing and the leakage, weak encapsulation or encapsulation sternly are not the key factors that causes battery air-blowing and leakage, and these all are because conventional package uses plane end socket encapsulation to cause mostly.When using the end socket encapsulation of this plane, the end socket surface smoothness is difficult to guarantee, easily forms the encapsulation bubble, or, form the encapsulation vacuole because electrolyte is too much, can't guarantee to seal fully when serious at all, form not encapsulation region of ribbon, exist very big encapsulation hidden danger.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provide a kind of be suitable for the plastic-aluminum envelope once with the end socket of secondary cell.
The utility model is a kind of be suitable for the plastic-aluminum envelope once with the end socket of secondary cell, be achieved by following technical proposals, described end socket is made up of upper cover and bottom head, at least one is oval or circular in upper cover and the bottom head, and another is plane, half elliptic or semicircle.
Half elliptic described in the utility model or its radian of semicircle end socket are identical or different with diameter.
The utility model is different with general end socket, and this end socket can two end socket surfaces all be oval or circular, also can be that one of them end socket surface is oval or circular, and another end socket surface is the plane.Have this structure, when encapsulation is used, the encapsulation meeting is encapsulated to face by line toward both sides from the summit of two end sockets, bubble in the time of can effectively discharging encapsulation, the vacuole that the electrolyte ejection forms in the time of also can discharging encapsulation more can prevent because the problem of the not packaging belt that plane end socket out-of-flatness forms guarantees good packaging effect, can also effectively guarantee simultaneously the package width that requires effectively to prevent battery air-blowing and leakage.

Embodiment
Below in conjunction with accompanying drawing part embodiment of the present utility model is elaborated.
As shown in Figure 1, in the present embodiment, on/surface of bottom head is ellipse or circular.Wherein 1 and 4 is end socket, and 2 and 3 is the surface of end socket, and their radian or diameter can be identical, also can be different.End socket 1 and 4 width can be 1-20mm, and length can be 10-1000mm.
As shown in Figure 2, in the present embodiment, the surface of upper cover is oval or circular, and the bottom head surface is the plane.Wherein 1 and 4 is end socket, and 2 and 3 is the surface of end socket, and the radian on end socket 2 surfaces or diameter can be arbitrarily. End socket 1 and 4 width can be 1-20mm, and length can be 10-1000mm.
As shown in Figure 2, in the present embodiment, the upper cover surface is the plane, and the surface of bottom head is oval or circular.Wherein 1 and 4 is end socket, and 2 and 3 is the surface of end socket, and the radian on end socket 2 surfaces or diameter can be arbitrarily. End socket 1 and 4 width can be 1-20mm, and length can be 10-1000mm.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection range of the present utility model.
