Abstract
The utility model relates to an anodal utmost point ear of cylindrical lithium -ion battery belongs to lithium cell spare part. The utility model provides a anodal utmost point ear of cylindrical lithium -ion battery, utmost point ear body are the aluminium strip, aluminium strip one end is connected on the mass flow body, and the aluminium strip other end is the fusible end of middle fretwork and both sides fretwork, and the fretwork of both sides is symmetrical at fusible end relief form, and middle fretwork is the same with the length of both sides fretwork. The utility model has the advantages of: for current utmost point ear, the anodal utmost point ear fusing temperature of this reality is low. When the outside short circuit of lithium cell or big multiplying power are discharged, adopt the utility model discloses an utmost point ear of lithium cell can fuse fast to improve the security performance of lithium cell. Through the cross -sectional area who reduces utmost point ear, reduce the fusing temperature of utmost point ear, when the outside short circuit of lithium cell or big multiplying power were discharged, extremely the ear can fuse fast to improve the security performance of lithium cell.
Description
Technical field
This utility model relates to a kind of cylindrical lithium ion battery positive pole ear, belongs to lithium battery parts。
Background technology
Having entered since 21st century, the requirement of the energy is increased severely day by day, there is pollution problem in the use of traditional resource, and how built environment is friendly and energy conservation type society is current subject matter。At energy field, the energy density of lithium battery Yin Qigao, self discharge are low, voltage advantages of higher, are widely used in the fields such as digital product, electric bicycle, space flight at present。But in this year, the unsafe incidents that lithium battery causes increases day by day, and the security performance how improving lithium battery is increasingly paid attention to。
Summary of the invention
This utility model relates to a kind of cylindrical lithium ion battery positive pole ear, the internal inflammable safety high that heats up when solving lithium battery external short circuit or big multiplying power discharging。
For achieving the above object, the technical solution adopted in the utility model is: cylindrical lithium ion battery positive pole ear, lug body is aluminium strip, described aluminium strip one end is connected on collector, the aluminium strip other end is the meltable end of middle hollow out and both sides hollow out, the hollow out of both sides is at meltable end symmetrical shape, and middle hollow out is identical with the length of both sides hollow out。
As preferably, the described meltable end two connector length between middle hollow out and both sides hollow out outboard end and lug body are 4-6mm, and two connector width sums are 0.5-0.7 times of lug body width。
As preferably, described connector length is 5mm, and two connector width sums are 0.6 times of lug body width。
The utility model has the advantage of: relative to existing lug, this reality positive pole ear fusing-off temperature is low。When lithium battery external short circuit or big multiplying power discharging, adopt lithium battery of the present utility model lug can quick fuse, thus improving the security performance of lithium battery。By reducing the cross-sectional area of lug, reduce the fusing-off temperature of lug, when lithium battery external short circuit or big multiplying power discharging, lug can quick fuse, thus improving the security performance of lithium battery。
