Abstract
The utility model relates to a flexibly-packaged elliptic battery, comprising a winding-formed battery core and a flexible shell wrapped on the periphery of the battery core, wherein the battery core is of an elliptic cylinder shape; and the flexible shell is of the elliptic cylinder shape as well and is wrapped on the periphery of the battery core which is of the elliptic cylinder shape. According to the flexibly-packaged elliptic battery, the battery core is wound into the elliptic cylinder shape, and the flexible shell which is of the elliptic cylinder shape is adopted for packaging, so that a whole elliptic battery is formed, therefore the elliptic battery can be applied to various types of cylindrical products; moreover, due to the adoption of an elliptic cylinder shape design, the whole battery cannot roll when being placed on the places, such as table surface, so that it is convenient to place.
Description
Technical field
The utility model relates to flexible-packed battery, more particularly, relates to a kind of flexible package ellipse battery.
Background technology
Present cylindrical battery generally is to adopt box hat, and the electric core behind the coiling of packing into is within it sealed up end cap again and encapsulated.Adopt the cylindrical battery of box hat encapsulation to exist production cost high, and when battery explosion takes place, can produce bigger damage, have certain danger.
And the square battery of some flexible packages has appearred in the market, comprises the electric core of coiling and molding and is wrapped in the peripheral square bladder of electric core.Yet this square battery can only be applied in the square electrical equipment groove, is difficult to adapt to for some columniform products (like electronics cigarette, talking pen etc.).
The utility model content
The technical problem that the utility model will solve is, a kind of flexible package ellipse battery applicable to cylindrical product is provided.
The utility model solves the technical scheme that its technical problem adopted: a kind of flexible package ellipse battery comprises the electric core of coiling and molding and is wrapped in the peripheral bladder of said electric core; Said electric core winding becomes oval column; Said bladder is similarly oval column, and the said electric core that is wrapped in said oval column is peripheral.
In the flexible package ellipse battery of the utility model, said electric core comprises positive plate, negative plate and the barrier film that is used to isolate said positive plate and negative plate; The two ends up and down of the said oval column electricity core behind the coiling are respectively equipped with anode ear and negative electrode lug; Said anode ear is connected with said positive plate spot welding; Said negative electrode lug is connected with said negative plate spot welding.
In the flexible package ellipse battery of the utility model, be respectively equipped with end cap at the two ends up and down of said oval column bladder; Be respectively equipped with the perforate that supplies said anode ear and negative electrode lug to stretch out on each said end cap; Between said anode ear and the said perforate, be equipped with lug glue between said negative electrode lug and the said perforate.
In the flexible package ellipse battery of the utility model, the outermost edge place of the electric core behind the said coiling is provided with the connection gummed paper of fixing said electric core shape.
In the flexible package ellipse battery of the utility model, the outermost layer of the electric core behind the said coiling is said positive plate, and the outer surface of outermost said positive plate is an aluminium foil layer.
In the flexible package ellipse battery of the utility model, said bladder is the aluminum plastic film shell.
Enforcement the utlity model has following beneficial effect: through electric core winding being become oval column, and utilize the bladder parcel of oval column, form whole ellipse battery, thereby can be to be used for various columniform products; And, because the design of oval column, make in the local time that entire cell being placed on desktop etc., be unlikely to roll convenient the placement.
Description of drawings
To combine accompanying drawing and embodiment that the utility model is described further below, in the accompanying drawing:
Fig. 1 is the schematic top plan view of electric core behind the coiling of the utility model flexible package ellipse battery;
Fig. 2 is the schematic perspective view of electric core behind the coiling of the utility model flexible package ellipse battery.
Embodiment
Like Fig. 1, shown in 2, be an embodiment of the flexible package ellipse battery of the utility model, can be used for some columniform products, like electronics cigarette, talking pen etc.This flexible package ellipse battery comprises the electric core of coiling and molding and is wrapped in the peripheral bladder 18 of electric core.
This electricity core comprises positive plate 11, negative plate 12 and the barrier film 13 that is used to isolate positive plate 11 and negative plate 12.The two ends up and down of the oval column electricity core behind the coiling are respectively equipped with anode ear 14 and negative electrode lug 15.Anode ear 14 is connected with positive plate 11 spot welding; Negative electrode lug 15 is connected with negative plate 12 spot welding, can avoid confusion identification more easily with negative electrode lug 15 through connect anode ear 14 at two ends.
In the present embodiment, the sticking connection gummed paper 16 that is provided with fixing electric core shape in the outermost edge place of the electric core behind the coiling, thus make electric core have comparatively fixed shape, and be unlikely to scatter, conveniently electric core is encased in the bladder 18.
This bladder 18 can aluminium plastic film shell, roughly is oval column, and two ends are respectively equipped with opening up and down, and seal opening through end cap is set.This end cap can select for use plastic cement or other materials to make, and each end cap is provided with perforate, from the end cap of correspondence, passes respectively with negative electrode lug 15 thereby be convenient to anode ear 14.
In order to seal the slit between lug and the end cap perforate; Between anode ear 14 perforate corresponding, be equipped with lug glue 17 between negative electrode lug 15 and its corresponding perforate with it; Thereby through heat-sealing during compound assembling, lug glue 17 can fusion, sealing and fixing anode ear 14 and negative electrode lug 15.
Further, when reeling, make that the outermost layer of electric core is a positive plate 11; And the outer surface of outermost positive plate 11 is an aluminium foil layer; The active material of for example removing positive plate 11 surfaces forms, contacts with bladder 18 through aluminium foil layer, thereby and form equipotential between the bladder 18; Avoid corrosion, improved the useful life of battery positive plate 11.
