Description

For making the casing of battery

Technical field

The utility model is sleeve technology field more particularly to a kind of for making the casing of battery.

Background technique

With the continuous development of battery technology, more requirements of the people for the performance proposition of battery.Battery it is ultra-thin Change is one important developing direction of battery.The realization important aspect of slimline battery is to rely on the gold overlayed on anode Belong to net.Existing mode is to apply to be covered with after bonded adhesives layer on positive electrode to cover upper metal mesh again, and this mode process is larger, And bonding is uneven, and firmness is not high.

Utility model content

In consideration of it, it is necessary to provide a kind of for making the casing of battery, when in use, preferably metal mesh can be covered On positive electrode.

The utility model provides a kind of for making the casing of battery, and described sleeve pipe is formed by multiply yarn woven, In, it include using first made of PET and using second made of conductive metal per one described wire rod.

Further, the conductive metal includes at least one of following: gold, silver, copper, aluminium, aluminium zircaloy.

Further, described sleeve pipe is the casing after flattening.

Further, including 12 strands of wire rods.

Compared to the prior art, the utility model is using PET and wire as one wire rod, then together by multiply wire rod Braiding, PET one one metal wires of correspondence, when reusing, PET equably covers on the metal filament after heating, and enables wire It is highly uniform steadily to overlay on positive electrode.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

The following detailed description will be further explained with reference to the above drawings the utility model.

Specific embodiment

In addition, term " first ", " second ", " third " are used for descriptive purposes only and cannot be understood as indicating or suggesting relative importance.

Provided by the utility model a kind of for making the casing 100 of battery, described sleeve pipe 100 passes through multiply wire rod 10 It weaves, wherein include using first 11 made of PET and using conductive metal system per one described wire rod 10 At second 12.

The conductive metal includes at least one of following: gold, silver, copper, aluminium, aluminium zircaloy.Especially, it should be noted that Using aluminium zircaloy as conductive metal, cost can be not only saved, but also corrosion resistance and mechanical performance can be improved, it is conductive It has excellent performance.

Described sleeve pipe 100 is the casing after flattening, since each strand material includes wire, in knitting forming Afterwards, casing can be flattened by press, obtains flat casing, be conducive to the subsequent use of casing, in use, can Form double-deck metal net layer.

The utility model includes 12 strands of wire rods, and ten twine materials are woven into described sleeve pipe.

The utility model weaves PET and wire as one wire rod, then by multiply wire rod together, PET correspondences One one metal wire equably covers on the metal filament after PET hot melt when in use, and after PET hot melt, second becomes metal net shaped Structure enables netted wire is highly uniform steadily to overlay on positive electrode.

In the description and claims of this application, word "comprises/comprising" and word " have/including " and its become Shape, for the presence of specified stated feature, numerical value, step or component, but do not preclude the presence or addition of it is one or more its His feature, numerical value, step, component or their combination.

Some features of the utility model, it is clear to illustrate, it describes in various embodiments respectively, however, these are special Sign, which can also be incorporated into single embodiment, to be described.On the contrary, some features of the utility model, for simplicity, only single It is described in embodiment, however, these features can also be independent or be described in different embodiments in any suitable combination.
