Description
Technical field
The utility model belongs to technical field of battery manufacture, relates to a kind of Z-shaped coating aluminium pole ears that is used for lithium battery and lithium ion battery, and this kind lug is specially adapted to the different lithium battery or the lithium ion batteries of structure of heavy-current discharge, and practicality is extensive.
Background technology
The fast development of mobile electronic equipment is had higher requirement to lithium battery and lithium ion battery.The lithium ion battery here comprises polymer Li-ion battery, flexible packing lithium ion battery, box hat lithium ion battery and plastic housing lithium ion battery.The structure of lithium battery and lithium ion battery mainly is divided into takeup type and stacked two big classes.When preparation lithium battery and lithium ion battery; At first process anode pole piece and cathode pole piece; Adopt modes such as riveted joint, ultrasonic spot welding or Laser Welding again; On anode pole piece, connect and be used for the aluminium pole ears of transmission current, at an end (i.e. " commentaries on classics nickel ") that connects the nickel lug on the aluminium pole ears with modes such as riveted joint, ultrasonic spot welding or Laser Welding, the other end with the nickel lug is connected on the IC circuit board at last then.Anode pole piece is to having " aluminium-aluminium ", " aluminium-nickel ", " nickel-copper " tie point or solder joint between the IC circuit board.Because these tie points or solder joint belong to a connection; The area of tie point or solder joint is little; Exist to connect or welding is not firm, virtual connections or rosin joint, tie point or solder joint get an electric shock indirectly that resistance is big, tie point or solder joint are easy to make the preparation battery have problems such as batch unstable properties problem such as depositing or use is oxidized.During battery discharge, particularly during heavy-current discharge, tie point or solder joint exist resistance excessive, inhomogeneous, cause problems such as caloric value is excessive, have obviously weakened the battery ability of externally doing work, and the insecurity that battery uses strengthens.In when charging, possibly exist the problems referred to above to cause the charging difficulty because of tie point or solder joint, cause the potential safety hazards such as heating, burning of battery.For this reason, in recent years, some researchers attempt nickel plating or other alloy on aluminium pole ears, to realize simplifying the preparation process and the purpose of improving the batch battery consistency of battery.
Utility model patent 200820009887.0 relate to a kind of aluminium strip base material one end surfaces be covered with nickel, copper, tin or other can be directly on the aluminium pole ears of metal of tin.Utility model patent ZL2008202125092 relates to a kind of lithium battery aluminium pole ears, comprises banded aluminum strip, at an end of aluminum strip chemical Ni-plating layer is arranged.The patent of invention of application number 200810143389X discloses a kind of lithium ionic cell positive pole ear and preparation method thereof.This patent uses the method for plating or electroless coating to form the firm non-aluminum metal layer of combination at the upper and lower surfaces of aluminum substrate layer one end, like nickel or tin-nickel alloy layer.Utility model patent 200820215661.6 and application number are that 200810236321.6 patent of invention all relates to the aluminium pole ears that an a kind of end has nickel dam.Wherein, nickel coating is packaging type or at the tow sides of an end of lug lamellar body or only positive or only on reverse side.Utility model patent 200920063603.0 relate to an a kind of end at aluminium compound the lug of non-aluminium alloy.The patent of invention of application number 2010101101270 relates to plating one deck nickel coating in a side end of SUS430 stainless steel band, copper strips, aluminium strip, nickel strap substrate elder generation, and the method for plating one deck tin coating again is with the preparation lug.Utility model patent 200920058776.3 relates to a kind of aluminium pole ears structure that need not change nickel, the nickel plating outside aluminium pole ears of its positive pole.Utility model patent 200920042215.4 relates to the aluminium pole ears coiled strip that a kind of poly-lithium battery uses, and one section nickel metal or nickel coating are arranged between this kind aluminium pole ears and the reel.
Because anode pole piece mainly plays conduction and thermolysis to the connecting portion between the IC circuit board.When carrying out high current charge-discharge; Above connecting portion maybe be because of expanded by heating; Influence switching performance, cause the variation of tie point contact resistance, therefore; In the lithium battery that adopts the coating aluminium pole ears, the resistivity, conductive coefficient and the coefficient of linear expansion that form alloy interface and coating itself between aluminum strip, aluminium and the coating are all influential to conduction and thermolysis.
From resistivity, in the time of 20 ℃, the resistivity of common metal is respectively copper 1.678 μ Ω cm, aluminium 2.65 μ Ω cm; Magnesium 4.39 μ Ω cm, nickel 6.93 μ Ω cm ((Hohn A. Dean, Lange's Chemistry Handbook, the 15th edition; Publishing house: McGraw-Hill, 1999), the resistivity of aluminium alloy is respectively; Aluminium silicon nickel alloy 5.95 μ Ω cm, hiduminium 5.95 μ Ω cm, magnalium nickel alloy 9.12 μ Ω cm (Zheng Feng chief editor; Aluminium and aluminium alloy quick checking handbook, Chemical Industry Press, Beijing: 2008.7. the 1st edition)); It is thus clear that usually the resistivity of aluminium alloy is above than being twice of fine aluminium and fine copper, and be more or less the same with the resistivity of nickel.On lug during through big electric current, the caloric value at the alloy position of formation is big in the middle of aluminum strip and the coating.And when coating was nickel dam, the caloric value of nickel coating was also bigger.
From 25 ℃ metal heat-conducting coefficient, argent 429W/ (mK), copper 401W/ (mK), aluminium 237W/ (mK), magnesium 156W/ (mK), nickel 90.9W/ (mK) (Hohn A. Dean, Lange's Chemistry Handbook; The 15th edition, publishing house: McGraw-Hill, 1999); The conductive coefficient of aluminium alloy is respectively; Aluminium silicon nickel alloy 159.1W/ (mK), hiduminium 113W/ (mK), magnalium nickel alloy 92.1W/ (mK).Thus it is clear that, the thermal conductivity ratio fine aluminium of aluminium alloy and fine copper much little, only more bigger than metallic nickel.When the heat that produces when each several part on the lug was identical, the rate of heat dispation of aluminum strip and copper coating was fast, and the rate of heat dispation of aluminium alloy and nickel coating is the slowest.It is thus clear that, adopting in the lithium battery of nickel-plated aluminum lug, the resistivity of the alloy-layer in the middle of nickel coating and the aluminum strip is maximum often; The heat that produces is maximum, and radiating effect is bad, therefore; With " commentaries on classics nickel " contrast; The nickel-plated aluminum lug of onesize strip under the heavy-current discharge condition, still produces high temperature because of heating easily.
Consider the structure difference of the lithium battery and the lithium ion battery of different battery enterprise production; Even the lithium battery of same enterprise production and lithium ion battery also will adopt the lug of different size according to battery types, battery structure, therefore being necessary for each lithium battery makes lug to measure.In order to overcome above deficiency; Reduce aluminium use amount, aluminium radiating rate, lug size taking into account; Particularly consider the standardization of lug preparation and the convenience of assembling, the waste of lug when avoiding battery enterprise to change the battery product kind, the utility model relates to a kind of Z-shaped coating aluminium pole ears.This aluminium pole ears is applied in lithium battery and the lithium ion battery, can rivets easily or weld together with the interface of metal of the IC circuit board of pairing.Avoided the battery assembling process " " process reduces the preparation process of battery, even under the condition of heavy-current discharge, is not easy to have improved the fail safe of battery because of heating produces high temperature to change nickel.
