Description

A kind of zinc-second time electroplating legal system of soaking is equipped with the method for nickel-plated aluminum lug
Technical field
The invention belongs to technical field of battery manufacture, relate to the preparation method of the nickel-plated aluminum lug of the lug of a kind of lithium cell and lithium ion battery, particularly polymer Li-ion battery, flexible packing lithium ion battery and the use of duricrust lithium ion battery.
Background technology
Aluminium and duraluminum have that density is little, ductility and good toughness, be easy to premium properties such as processing, extensively as the lug of lithium cell and lithium ion battery, particularly as the lug of polymer Li-ion battery, flexible packing lithium ion battery and duricrust lithium ion battery.Yet, the own corrosion-vulnerable of aluminium and duraluminum, big, the welding difficulty of not wear-resisting, contact resistance.And the nickel metallic surface can generate passive film as thin as a wafer rapidly, than aluminium pole ears better opposing corrosive power is arranged.Therefore, adopt modes such as riveted joint, ultrasonic spot welding or LBW more, on the aluminium pole ears that battery uses, connect nickel lug (promptly changeing nickel), the other end with the nickel lug is welded on the IC circuit card again.Like this, anode pole piece exists between the IC circuit card " aluminium-aluminium ", " aluminium-nickel ", " nickel-copper " several tie points (or solder joint).Because this tie point (or solder joint) belongs to a connection; The area of tie point (or solder joint) is little; Exist to connect that (or welding) is not firm, virtual connections (or rosin joint), tie point (or solder joint) contact resistance are big, tie point (or solder joint) is prone to problems such as oxidized when depositing, there are problems such as batch instability in the battery of preparation.When discharging, particularly during heavy-current discharge, possibly there are problems such as resistance is excessive, heating is excessive in tie point (or solder joint), the battery ability of externally doing work is obviously weakened, the insecurity that also causes battery to use.In when charging, possibly cause potential safety hazards such as heating that charging difficulty and charging cause, burning because of the sealing-off of tie point (or solder joint) and welding resistance are excessive.In addition, change the step that has increased cell preparation in the nickel process, increase battery cost.
In order to overcome above deficiency, the present invention provides the method for the nickel-plated aluminum lug of cutting on the large stretch of nickel plating aluminium flake of preparation.This nickel-plated aluminum lug can be extensively as the lug of lithium cell and lithium ion battery, particularly as the lug of polymer Li-ion battery, flexible packing lithium ion battery and duricrust lithium ion battery.During as the lug of lithium cell and lithium ion battery, anode pole piece has only between the IC circuit card with nickel-plated aluminum lug of the present invention " aluminium-aluminium ", " nickel-copper " two tie points.Point between original " aluminium-nickel " is connected face connection or the body connection of changing into " aluminium-nickel plating alloy ", obviously reduced contact resistance, improved the wearing quality of connecting zone, improved the consistence of different batches battery.The charge-discharge performance of battery, particularly high rate during charging-discharging have been improved.
Utility model patent ZL2008202125092 relates to a kind of lithium cell aluminium pole ears, comprises banded aluminum strip, at an end of aluminum strip chemical Ni-plating layer is arranged.But, this patent does not relate to the concrete preparation method of nickel-plated aluminum lug and complete structure formation.Though existing many papers and patent relate to the method for nickel plating on the aluminium; The method that relates to a kind of nickel plating on siliceous aluminum steel, sheet, rod like patent ZL 018091091; Patent relates to a kind of method of nickel plating on printed substrate; Patent ZL981149332 relate to a kind of on steel substrate the method for electroplating of low-stress nickel, patent CN101245480 relates to a kind of method at carbon, iron, copper electroplating nickel on surface.But, these patents all do not relate to a kind of method that is suitable as the nickel plating of battery aluminium pole ears.Since the nickel-plated aluminum lug that is used for lithium (ion) battery to the requirement of nickeling layer and common nickel plating aluminium flake to coating require different; Wherein, What want high spot review is factors such as contact resistance, resistance to bend(ing) ability, heat dispersion between nickeling layer and the aluminium flake in the nickel-plated aluminum lug, does not need to be concerned about for the luminance brightness of nickel plating aluminium flake.
