Description
Technical field
The anode ear technical field of structures of battery is the utility model is related to, is specially a kind of cathode of polymer battery
Ear structure.
Background technology
Lug is as polymer battery important component, including anode ear and negative electrode lug, and it acts as in connection battery core
Positive/negative plate, and with outside electric loading or the electric transmission of equipment.Wherein negative electrode lug is generally by nickel strap or copper strips and gel
(CPP glue) is composed by certain size, and anode ear is made of aluminium strip welding ends aluminium strip and exposed junction nickel strap, and exposed junction passes through
Laser welding transfers aluminium strip together, is composed with gel (CPP glue) by certain size.Positive and negative lug is divided into outer
Reveal end, gel position, pole piece welding ends three parts.Anode ear aluminium strip material self character is relatively soft, and easy brittle failure,
Its tab welding end is fixed on positive plate with pole piece through ultrasonic bonding in cell fabrication processes, but lug exposed junction is then easy
There is phenomena such as crooked and bending, such as with being be easy to cause just in the case of the multiple crooked, bending of nickel strap change-over terminal same position
Lug aluminium strip is broken, and positive and negative anodes short circuit is then easy to cause in the case that battery is powered after charging when battery.
For this reason, it is necessary to be improved from extreme ear structure, both can reach fix anode ear be less prone to it is crooked, bending
Effect, and do not influence production efficiency, also do not increase any fund input.
Utility model content
The purpose of this utility model is to provide a kind of cathode ear structure of polymer battery, to solve outside existing lug
Then easily there is phenomena such as crooked and bending in dew end, such as in the case of with the multiple crooked, bending of nickel strap change-over terminal same position
The fracture of anode ear aluminium strip is be easy to cause, asking for positive and negative anodes short circuit is then easy to cause in the case that battery is powered after charging when battery
Topic.
To achieve the above object, the utility model provides a kind of anode ear knot of following polymer battery of technical solution
Structure, including gel, pole piece welding ends, turn nickel gap, PACK welding ends, aluminium-to-nickel lug and gel and overlap position with turning nickel,
The aluminium-to-nickel lug left end is provided with PACK welding ends, and is connected on the right side of PACK welding ends with turning nickel gap, described to turn nickel
It is connected with pole piece welding ends on the right side of gap, and pole piece welding ends and upper and lower both sides are provided with gel between turning nickel gap, institute
State and be provided with gel on the right side of PACK welding ends between gel and overlap position with turning nickel.
Preferably, the gel is both provided with CPP glue in both sides up and down.
Preferably, the pole piece welding ends and turn nickel gap material and be disposed as aluminium strip.
Preferably, the PACK welding ends material is arranged to nickel strap.
Preferably, the gel is 0.7-1.3mm with turning nickel to overlap bit width scope, and gel overlaps position with turning nickel
Position be arranged on and turn nickel gap and PACK welding ends overlappings.
Compared with prior art, the beneficial effects of the utility model are：The cathode ear structure of the polymer battery provides
A kind of new gel glue sealing structure, in anode ear material, turns the immovable situation of nickel structure, gel is by upper and lower two layers
CPP glue coated metals band overlap it is encapsulated together, by aluminium strip and turn in encapsulation together with nickel strap part and gel seal
As an entirety, fixation is played, since nickel strap material is harder, crooked, bending is less prone to, effectively avoids causing
Fracture, short circuit phenomenon.
