Abstract
A lithium ion battery with a three-dimensional nickel chip aims to solve the problem that hidden dangers of false welding are caused by a plurality times of welding and more materials are wasted in the prior art, and is characterized by comprising a battery cell and a protective board, wherein the battery cell is provided with the three-dimensional nickel chip and a battery cell negative pole; the three-dimensional nickel chip is provided with a convex first long nickel chip; the protective board is provide with an positive pole contact chip and a negative pole contact chip; the positive pole contact chip is provided with a convex second long nickel chip; the first nickel chip and the second long nickel chip are in spot welding connection; the battery cell negative pole is welded on the negative pole contact chip in a spot welding manner through a leading nickel chip. According to the utility model, the three-dimensional nickel chip is welded with the head part of the battery cell, so that the risk of false welding of the plurality times of welding is effectively lowered, the probability of decreasing failure in charging and discharging of an end battery can be effectively guaranteed, and the cost in the battery processing process is obviously reduced.
Description
Technical field
The utility model relates to the preparation field of square lithium ion battery in the chemical power source preparation, more specifically relates to a kind of lithium ion battery with the three-dimensional nickel sheet.
Background technology
Existing lithium ion battery generally adopts at battery cephalosome laser welding or plane aluminum-nickel compound piece of ultrasonic bonding; the battery assembling is advanced to go and is turned the nickel welding; welding nickel sheet lead-in wire on the plane aluminum-nickel compound piece welded at battery cephalosome, and then assembling on baffle by nickel sheet wire bonds.Existing technique is generally will be through three process battery cephalosome welding plane aluminum-nickel compound piece → turn nickel welding nickel sheet → nickel sheet wire bonds to the technique on baffle.
Existing technique is because having three butt weldings and being the welding of different materials, therefore can exist multiple welding to bring the hidden danger of rosin joint and need the more material of waste.
Summary of the invention
The purpose of this utility model is: a kind of lithium ion battery with the three-dimensional nickel sheet is provided, to solve prior art, exists multiple welding to bring the hidden danger of rosin joint and the problem that needs to waste more material.
Reach the purpose of this utility model; the technical scheme adopted is: a kind of lithium ion battery with the three-dimensional nickel sheet; it is characterized in that: comprise battery core and baffle; described battery core is provided with three-dimensional nickel sheet and battery core negative pole; the three-dimensional nickel sheet is provided with the first long nickel sheet of protrusion; described baffle is provided with anodal contact chip and negative pole contact chip; anodal contact chip is provided with the second long nickel sheet of protrusion; the described first long nickel sheet is connected by spot welding with the second long nickel sheet, and the battery core negative pole connects nickel sheet point and is welded in the negative pole contact chip by drawing.
The beneficial effect that the utility model reaches is: adopt battery core head welding three-dimensional nickel sheet of the present utility model can effectively reduce the risk of multiple welding rosin joint, the probability that makes end cell discharge and recharge inefficacy obtains effectively reducing and guaranteeing, and for cell processing course, obvious cost savings is arranged.
The accompanying drawing explanation
Fig. 1: core strueture schematic diagram of the present utility model.
Fig. 2: baffle structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, architectural feature of the present utility model more at large is described.
A kind of lithium ion battery with the three-dimensional nickel sheet; it is characterized in that: comprise battery core 1 and baffle 2; described battery core 1 is provided with three-dimensional nickel sheet 3 and battery core negative pole 4; three-dimensional nickel sheet 3 is provided with the first long nickel sheet 5 of protrusion; described baffle 2 is provided with anodal contact chip 6 and negative pole contact chip 7; anodal contact chip 6 is provided with the second long nickel sheet 8 of protrusion, and the described first long nickel sheet 5 is connected by spot welding with the second long nickel sheet 8, and battery core negative pole 4 connects nickel sheet point and is welded in negative pole contact chip 7 by drawing.
Adopt the utility model battery core 1 head welding three-dimensional nickel sheet 3 to replace existing header planes aluminum-nickel compound piece; exempt the processing welding in when assembling processing and turn nickel and draw and connect nickel sheet lead-in wire to realize battery core; be that battery core is used the three-dimensional nickel sheet when the later stage, battery core processing was assembled; the the first long nickel sheet protruded on three-dimensional nickel sheet 3 directly is welded on the second long nickel sheet 8 on processing assembling baffle 2; exempt battery core 1 with this and use the plane aluminum-nickel compound piece need to turn nickel processing welding nickel sheet lead-in wire when processing is assembled, reduce manufacturing procedure, weld the rosin joint risk and save the nickel sheet material.
