Description
Technical field
The present invention relates to technical field of lithium ion more particularly to a kind of lithium ion cell polar ear shaping, rubberizing sides
Method.
Background technology
Stack type lithium ion battery mainly has Z-shaped lamination and takeup type lamination, Z-shaped lamination mainly first will just at present
Cathode pole piece respectively by cutting, stamp, form the monolithic pole piece with false lug, diaphragm is in Z-shaped lap wound, positive and negative anodes pole
Piece intersects successively to be stacked, and centre is separated by diaphragm.Positive and negative anodes vacation lug and positive and negative anodes lug are whole by welding after lamination
It is combined, while headspace being made to increase, inside battery space availability ratio reduces.
Invention content
It is an object of the invention to overcome above-mentioned shortcoming in the prior art and provide it is a kind of simple in structure, it is practical
Lithium ion cell polar ear shaping, sticking method.
The present invention realizes in the following way：
A kind of lithium ion cell polar ear shaping, sticking method, it is characterised in that：It is specific as follows：In battery roll core ontology
The left and right sides is sticked respectively side glue；The battery roll core body bottom portion is connected with bottom glue；The battery roll core ontology
Top is connected with anode ear and negative electrode lug, is connected with positive false lug by ultrasonic welding on the anode ear and negative electrode lug and bears
Extremely false lug；The anode vacation lug and cathode vacation lug form welding position with the junction of anode ear and negative electrode lug respectively；
The welding position and battery roll core body upper part are touched using lug rubberizing cladding, then by anode ear and negative electrode lug carry out to
Upper 90 degree of folds, make anode ear and negative electrode lug and battery roll core ontology in vertical state, again by welding position together with anode ear
It carries out upward 90 degree of folds again with negative electrode lug, welding position is made to be located at the top of battery roll core ontology.
Further, the side glue is three.
The beneficial effects of the present invention are：Wherein welding position is reserved size and can be adjusted according to core thickness, ensures
The firmness of tab welding makes the metal burr that welding, shearing generate be isolated with diaphragm by carrying out rubberizing to welding position
It comes, prevent core top diaphragm from being punctured by metal burr, improve the security performance of battery；Welding position is turned down to core top
Portion can improve and utilize inside battery space, battery core energy density, and simple for process easy to operate with obvious effects, there is greater significance.

Specific implementation mode
Below by specific embodiment, and in conjunction with attached drawing, technical scheme of the present invention will be further explained in detail.It answers
Work as understanding, embodiments of the present invention are not limited to the following examples, the accommodation in any form done to the present invention
And/or changes and fall within the scope of the present invention.
Embodiment：
A kind of lithium ion cell polar ear shaping, sticking method, it is specific as follows as shown in Fig. 1-Fig. 7：In battery roll core ontology
3 left and right sides be sticked respectively there are three side glue 4；3 bottom of battery roll core ontology is connected with bottom glue 5；Battery roll core sheet
The top of body 3 is connected with anode ear 1 and negative electrode lug 2, and positive false pole is connected with by ultrasonic welding on anode ear 1 and negative electrode lug 2
Ear 7 and cathode vacation lug 8；Positive vacation lug 7 and cathode vacation lug 8 are formed with the junction of anode ear 1 and negative electrode lug 2 respectively to be welded
Socket part position 6, and redundance other than welding position 6 is cut；Welding position 6 and 3 top of battery roll core ontology use lug
The cladding of rubberizing 9 touch, and anode ear 1 and negative electrode lug 2 are then carried out upward 90 degree of folds, make anode ear 1 and negative electrode lug 2 and battery
Welding position 6 in vertical state, is carried out upward 90 degree of folds by core ontology 3 again together with anode ear 1 and negative electrode lug 2 again,
Welding position 6 is set to be located at the top of battery roll core ontology 3.
Welding position 6 in the present embodiment is reserved size and can be adjusted according to the thickness of battery roll core ontology 3, ensures just
The firmness that lug 1 and negative electrode lug 2 weld, by carrying out rubberizing to welding position 6, the metal kernel for making welding, shearing generate
Thorn keeps apart with diaphragm, prevents the diaphragm at 3 top of battery roll core ontology from being punctured by metal burr, improves the safety of battery
Energy；By the fold of welding position 6 to 3 top of battery roll core ontology, can improve using inside battery space, battery core energy density, and
It is simple for process easy to operate with obvious effects, there is greater significance.
Example the above is only the implementation of the present invention is not intended to limit the scope of the invention, every to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
