Description
Technical field：
The utility model is related to a kind of high efficiency lithium ion cell polar ears, belong to lithium ion battery production technical field.
Background technology：
In recent years, with the rapid development of microelectric technique, the device requirement amount of miniaturization is increasing, is wanted to battery
Ask higher and higher.Important component of the lithium ion battery as field of batteries, energy density height high with its voltage, self discharge
The advantages that small, memory-less effect, it is widely used in digital camera, mobile phone, notebook etc..But in recent years, lithium from
Safety problem is increasing caused by sub- battery, how effectively to improve the security performance of lithium ion battery as weight at this stage
Want research direction.
Currently, after battery production is wound by positive plate and negative plate by wound membrane, then anode and cathode are welded, mesh
After the problem of preceding welding is welding, welding print can be all left on copper foil and aluminium foil, be unfavorable for battery beauty, metal pole
Ear leakage is also easy to scratch aluminum plastic film, influences the performance battery of battery and is unfavorable for the production of battery.
Utility model content：
In view of the above-mentioned problems, the technical problem to be solved by the present invention is to provide a kind of high efficiency lithium ion cell electrodes
Ear.
A kind of high efficiency lithium ion cell polar ear of the utility model, it includes battery body, battery core positive and negative anodes and metal
Lug is provided with battery core positive and negative anodes on battery body, and battery core positive and negative anodes are L-type structure design with metal tabs, and battery core is positive and negative
Pole is docked with one end of metal tabs, and passes through ultrasonic welding.
The beneficial effects of the utility model：It is reasonable in design, make it is simple, it is easy to use, by by metal tabs
Be designed as L-type structure with battery core positive and negative anodes, and by ultrasonic welding, not only battery is aesthetic in appearance after having welded, and battery with
The contact position welding of lug prints, and metal tabs will not be caused to leak outside, not damaged to aluminum plastic film, foil can be by metal tabs
It surrounds completely, security performance is high.
Description of the drawings：
The utility model is described in detail by following specific implementations and attached drawing for ease of explanation,.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the overall structure diagram after the utility model welding.
1- battery bodies；2- battery core positive and negative anodes；3- metal tabs.
Specific implementation mode：
As Figure 1-Figure 2, present embodiment uses following technical scheme：It is positive and negative comprising battery body 1, battery core
Pole 2 and metal tabs 3 are provided with battery core positive and negative anodes 2 on battery body 1, and battery core positive and negative anodes 2 and metal tabs 3 are L-type structure
Design, battery core positive and negative anodes 2 are docked with one end of metal tabs 3, and pass through ultrasonic welding.
Present embodiment is reasonable in design, makes simply, easy to use, by the way that metal tabs and battery core are positive and negative
Pole is designed as L-type structure, and by ultrasonic welding, not only battery is aesthetic in appearance after having welded, but also contact of the battery with lug
Position welding print, will not cause metal tabs to leak outside, not damaged to aluminum plastic film, and foil can surround metal tabs completely,
Security performance is high.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
