Background technology
At present, along with the enforcement that national new forms of energy are planned, Prospect of EVS Powered with Batteries receives much concern, and known lithium-ion-power cell need meet the requirements such as heavy-current discharge, high rate cyclic and longer useful life, thus has special requirement to the bus-bar of battery.
In the battery of existing electrokinetic cell producer, bus-bar adopts bolt to pass cell substrates and nut connected mode mostly.After battery loading operation a period of time, the vibrations because of vehicle probably cause loosening and coming off of clamp nut, cause potential safety hazard, and because of bolt, between nut and battery pole plates three, contact-making surface is little, dispel the heat uneven, the useful life of serious curtailment battery.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of lithium-ion-power cell and processing method thereof, its bus-bar connects more firm, uses stability and safety more, good heat dissipation effect, long service life.
The present invention is achieved by the following measures:
A kind of lithium-ion-power cell of the present invention, comprises the housing of upper end open, bus-bar and core,
The two ends, left and right of described core lead to pole plate, and described bus-bar comprises vertical draw-in groove, and a side of draw-in groove is extended with welded plate downwards, and described pole plate top embeds in draw-in groove and together with pressing with draw-in groove, the bottom supersonic welding of pole plate is connected on welded plate.
Above-mentioned draw-in groove top is provided with the transitional slope of 45 degree.
The length of above-mentioned draw-in groove is 45 ~ 50mm, and the width of draw-in groove is 2 ~ 3mm, and the length of welded plate is
18~23mm。
The processing method of lithium-ion-power cell of the present invention, comprises the following steps:
A. be rolled into core and draw pole plate at two ends, left and right, pole plate being shaped to vertical bar shape;
B. make the rectangle housing of bus-bar, cover plate and upper end open, the structure of bus-bar comprises vertical draw-in groove, and a side of draw-in groove is extended with welded plate downwards;
C. bus-bar is arranged on core two ends, the top of pole plate to be embedded in draw-in groove and to press together, adopts ultrasonic bonding by pole plate lower weld on welded plate;
D. core is loaded in housing together with bus-bar, clamp-on between bus-bar and housing sidewall insulation every
Plate, and fix.
The invention has the beneficial effects as follows:
Past and the point cantact of battery pole plates are connected and becomes face and contact, be connected with ultrasonic bonding twice by riveting, effectively make that bus-bar and battery pole plates are firm to be connected, ensure that stability and fail safe; Simultaneously because contact-making surface increases, the even heat that battery is produced when discharging distributes, and improves useful life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of bus-bar of the present invention.
Wherein: 1 core, 2 pole plates, 3 welded plates, 4 draw-in grooves, 5 transitional slopes.
