Abstract
The utility mode relates to a lithium ion battery anode tab belongs to lithium ion battery and makes technical field. The utility model provides a lithium ion battery anode tab, utmost point ear body is the aluminium strip, characterized by, a middle part side indent of utmost point ear body, the bottom of indent are equipped with the hole, the lower thickness of the indent of utmost point ear body be 0.5 of ear thickness extremely 0.6 doubly, the both sides in hole part width and be 0.4 of ear body width extremely 0.5 doubly. The utility model discloses an advantage does: through the partial thickness that reduces lithium ion battery anode tab to reducing the sectional area of this part, reducing the fusing temperature of utmost point ear, when lithium ion battery short circuit or discharge current were too big, the quick -break caused lithium ion battery to open circuit, improves lithium ion battery's security performance.
Description
Technical field
This utility model belongs to technical field of lithium-ion battery, is specially a kind of new type lithium ion battery positive pole ear.
Technical background
In recent years, along with developing rapidly of microelectric technique, the device requirement amount of miniaturization is increasing, and the requirement to battery is more and more higher.Lithium ion battery, as the important component part of field of batteries, with advantages such as its voltage height, energy density height, little, the memory-less effects of self discharge, is widely used in the aspects such as digital camera, mobile phone, notebook.But the safety problem that in recent years, lithium ion battery caused is increasing.The security performance the most effectively improving lithium ion battery becomes the important research direction of present stage.
Summary of the invention
The purpose of this utility model is to provide a kind of lithium ionic cell positive pole ear, improves lithium battery safety in the case of short circuit or discharge current are excessive.
For achieving the above object, the technical solution adopted in the utility model is:
Lithium ionic cell positive pole ear, lug body is aluminium strip, it is characterized in that, the middle part one side indent of described lug body, the bottom of indent is provided with hole, 0.5-0.6 times that indent lowest part thickness is lug thickness of lug body, the two side portions width in hole and be 0.4-0.5 times of lug body width.
As preferably, the concave shaped camber concave surface of described this body side surface of lug.
As the most preferably, the hole bottom described indent is square shape hole, and the dual-side in square shape hole is parallel with lug body side.
As further preferred, the two side portions width in described square shape hole and be 0.5 times of lug body width.
As preferably, the hole bottom described indent is circular hole, and Circularhole diameter is 0.5 times of lug body width.
Advantage of the present utility model is: by reducing the segment thickness of lithium ionic cell positive pole ear, and reduce the sectional area of this part, reduce the fusing-off temperature of lug, when lithium ion battery short circuit or discharge current are excessive, fusing rapidly, cause lithium ion battery open circuit, improve the security performance of lithium ion battery.

Detailed description of the invention
This utility model is as shown in the figure:
Lithium ionic cell positive pole ear, lug body 1 is aluminium strip, and the middle part one side indent 2 of described lug body 1, the bottom of indent is provided with hole 3.
Embodiment 1
The indent 2 of lug body 1 side forms arc-shaped concave, and the hole 3 bottom indent is square shape hole, and the dual-side in square shape hole is parallel with lug body 1 side.0.5-0.6 times that indent lowest part thickness is lug thickness of lug body, the two side portions width in square shape hole and be 0.5 times of lug body width.
Embodiment 2
The indent 2 of ear body 1 side forms arc-shaped concave, 0.5-0.6 times that indent lowest part thickness is lug thickness of lug body, and the hole 3 bottom described indent is circular hole, and Circularhole diameter is 0.5 times of lug body 1 width.
By reducing the segment thickness of lithium ionic cell positive pole ear, and reduce the sectional area of this part, reduce the fusing-off temperature of lug, when lithium ion battery short circuit or discharge current are excessive, fusing rapidly, causes lithium ion battery open circuit, improves the security performance of lithium ion battery.
