Abstract

The utility model discloses a flexible packaging lithium cell edging structure including a flexible packaging finished lithium cell and folded edges of sealing edges on two sides, which is characterized in that the folded edges of sealing edges on two sides are outwardly overturned. The utility model has the advantages that the lithium cell with the thickness less than 5.0mm after being folded conforms to standard requirements due to the outwardly-overturned folded edges; the special utilization of the lithium cell can be improved through utilizing the outwardly-overturned sealing edges on two sides, the lithium cell with high power capacity can be designed and ultrathin batteries can be manufactured due to the outwardly-overturned folded edges.

Description

A kind of flanging structure of flexible package lithium cell

[technical field]

The utility model relates to a kind of flexible package lithium cell, particularly relates to a kind of novel flanging structure of flexible package lithium cell.

[background technology]

At present, in all kinds lithium battery, flexible package lithium cell is with high-energy-density, and is in light weight, form make by oneself advantage, be used in widely in the mobile digital series products.The external packing of flexible-packed battery is a kind of soft composite package film, in packaging process, comprises that a technology is; Flexible package finished product lithium cell fold method is that both sides are sealed the limit and inwardly turned down.As shown in Figure 1: the flanging limit that seal flexible package lithium cell 1 both sides inwardly turns down, if electric core 1 thickness is during less than 5.0mm, the thickness behind the electric core flanging exceeds standard-required easily, and electric core flanging operation easier is bigger.

[summary of the invention]

The utility model is to overcome the deficiency that prior art exists, and a kind of flanging structure of turning up is provided, and guarantees ultra-thin electric core, improves electric core space utilization, can design higher capacity electricity core.

To achieve these goals, the flanging structure of a kind of flexible package lithium cell of the utility model comprises flexible package finished product lithium cell, and both sides seal the edge break limit, and it is characterized in that: the flanging that seal both sides outwards turns down.

Advantage of the present utility model is:

1. because outside flanging, thus guarantee thickness less than the electric core of 5.0mm through conformance with standard requirement behind the flanging.

2. because outside flanging can seal the limit by utilizing outside turnover both sides, improve, can design higher capacity electricity core, and produce ultra-thin battery electric core space utilization.

[description of drawings]

Fig. 1 is the flanging structure of prior art flexible package lithium cell.

Fig. 2 is the structure principle chart of the flanging structure of a kind of flexible package lithium cell of the utility model.

[embodiment]

As shown in Figure 2: the flanging structure that the utility model product discloses a kind of flexible package lithium cell comprises flexible package finished product lithium cell 2, and both sides seal edge break limit 21, and the flanging that seal described both sides outwards turns down.

Advantage of the present utility model is:

1. because outside flanging, thus guarantee thickness less than the electric core of 5.0mm through conformance with standard requirement behind the flanging.

2. because outside flanging can seal the limit by utilizing outside turnover both sides, improve, can design higher capacity electricity core, and produce ultra-thin battery electric core space utilization.

The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.

Claims (1)

1, a kind of flanging structure of flexible package lithium cell comprises flexible package finished product lithium cell, and both sides seal the edge break limit, and it is characterized in that: the flanging that seal both sides outwards turns down.
