Abstract
The invention discloses a tab which can be mounted and welded omnidirectionally and improves a production yield of a battery. The tab is characterized by being made of an aluminium metal. The tab comprises a tab A end and a tab B end, wherein the tab A end is arranged outside the battery C, and the tab B end is arranged in the battery C and is connected to an electrode material D in the battery C.
Description
Technical field
The present invention relates to a kind of battery pole ear, be specifically related to a kind of lithium battery pole ear.
Background technology
Lithium battery is a class is negative material, the battery using non-aqueous electrolytic solution by lithium metal or lithium alloy.The lithium battery occurred the earliest comes from great inventor Edison, uses following reaction: this reaction of Li+MnO2=LiMnO2 is redox reaction, electric discharge.Because the chemical characteristic of lithium metal is very active, make the processing of lithium metal, preservation, use, very high to environmental requirement.So lithium battery is not applied for a long time.Present lithium battery becomes main flow.
At present, in all kinds lithium battery, flexible package lithium cell, with high-energy, the advantage such as lightweight, form is made by oneself, obtains and uses widely.The lug that existing flexible package lithium cell adopts or the lug of original technique, this lug not only will consider its soldering angle in design uses, and in welding process, difficulty is also higher, and secondly, earphone very easily fractures and causes scrapping of whole battery aborning.
Summary of the invention
The present invention can full angle erection welding in order to provide one, improves the lug of battery production rate of finished products.
The technical solution adopted in the present invention is: a kind of flexible package lithium cell lug, it is characterized in that: described ear pole material is metallic aluminium, described lug is divided into lug A to hold and lug B holds, it is outside that described lug A end is arranged on battery C, described lug B end is arranged in battery C, and described lug B end is connected with battery C inner electrode D.Wherein, described lug A holds shape to be cylindrical, and diameter is 0.1-80mm, and described lug B holds as sheet metal, and thickness is 0.02-5mm.
As preferably, described lug A end surfaces is coated with metal copper film or metal nickel film.
As preferably, described lug A end is formed as elliptical cylinder-shape, and oval half is 0.1-90mm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, a kind of flexible package lithium cell lug, it is characterized in that: described ear pole material is metallic aluminium, described lug is divided into lug A to hold and lug B holds, it is outside that described lug A end is arranged on battery C, described lug B end is arranged in battery C, and described lug B end is connected with battery C inner electrode D.Wherein, described lug A holds shape to be cylindrical, and diameter is 0.1-80mm, and described lug B holds as sheet metal, and thickness is 0.02-5mm.
As preferably, described lug A end surfaces is coated with metal copper film or metal nickel film.
As preferably, described lug A end is formed as elliptical cylinder-shape, and oval half is 0.1-90mm.
