Abstract
The invention provides a method for connecting a high-capacity metal shell battery pole and a top cover, which comprises the steps of punching a through hole for connection on the top cover, injecting an insulating layer in the through hole and around a port, manufacturing the pole with a bottom plate and bending the pole into 90 DEG C0The pole lug connecting sheet is matched with corresponding connecting holes, and finally, the pole bottom plate and the pole lug connecting sheet are firmly connected by metal rivets on the front surface and the back surface of the top cover respectively. The method is used for assembling the high-capacity lithium ion electrode posts, the posts cannot be twisted due to the action of external force, the airtight insulation property of the battery shell can be enhanced, and the safety and reliability of the battery are improved.
Description
Technical field
The present invention relates to big capacity metal-back battery electrode column and the top cover method of attachment more than 50Ah of a kind of assembly method of high-capacity lithium battery metal-back, particularly capacity.
Background technology
Research to big capacity metal-back battery at present still is in the starting stage; Existing small-capacity cells method for designing is all used in the design of common metal housing battery; Pole adopts circular port with being connected of top cover, and the inner method of liner polypropylene or polytetrafluoroethylplastic plastic that adopts in hole is carried out insulation processing.Because the cooperation of circular port makes pole under the situation that receives the external force twisting, rotate easily, thereby the structure of battery electrode column part is changed, be easy to cause the deformation of liner, the result makes battery gas leakage.More serious result is, when battery after repeatedly twisting, pole partly causes loosening, the pole piece of inside battery possibly misplace, thereby causes that internal short-circuit of battery brings potential safety hazard.
Summary of the invention
The object of the present invention is to provide the airtight insulating properties of a kind of enhancing battery container, improve the useful life of battery and the big capacity metal-back battery electrode column and the top cover method of attachment of reliability.
The objective of the invention is to realize through following technical scheme: (1) is the center with the pole position on battery cap, around it, stamps out 2～4 Φ 3～25mm through holes;
(2) the thick insulating barrier of injection moulding 0.3～3mm around the inwall of through hole and port;
(3) make the pole that the lower end has base plate, and joining through hole respective connecting on work and the top cover on the base plate;
(4) making is bent into 90
0The lug brace, the negative electrode lug brace is used red copper, positive ear connecting sheet is used fine aluminium, joining respectively on the brace do with pole base plate and utmost point crowd lug on the connecting hole respective connecting;
(5) front and back at top cover is connected firmly pole base plate and lug brace respectively with metal rivet.
The present invention prevents battery electrode column transfer under external force, is aided with integrated injection moulding insulation spacer simultaneously, has increased the airtight insulating properties of battery, has improved the fail safe and the reliability of high-capacity lithium battery greatly, has improved the serviceability of lithium battery.
Embodiment
Embodiment operates as follows:
1, on battery cap, is the center, around it, stamps out 4 Φ 4.5mm through holes with the pole position;
2, integrated through injection molding teflon insulation layer around through-hole wall and port, thickness 0.8mm;
3, make the lower end and have the pole of base plate, and on base plate, join through hole respective connecting in work and the step 1;
4, making is bent into 90
0The lug brace of thick 1mm, wherein the both positive and negative polarity brace is used fine aluminium and red copper respectively, joining on the brace do with pole base plate and utmost point crowd lug on the connecting hole respective connecting;
5, the front and back at top cover is connected firmly pole base plate and lug brace respectively with metal rivet.
