Description
Technical field
The invention belongs to field of batteries, refer to a kind of battery lead of mobile terminal especially.
Background technology
In recent years, along with the extensive use of portable type electronic product, battery supporting with it also comes into one's own.And, along with the miniaturization of electronic product, the trend of lightness, for it provides the capacitance of the secondary cell of electric energy and weight to occupy critical positions in miniaturization of electronic products and lightweight, particularly to be widely used as the requirement of power supply to battery of small-sized portable electronic product more important for lithium ion battery.The battery of portable phone has battery main body, protective circuit, metal lead wire, input and output terminal and shell between battery main body and protective circuit.Wherein, for metal lead wire, its connection with other parts is realized by spot welding usually, because spot welding is to battery or other parts almost do not have thermal impact and welding efficiency is high.
The battery lead of existing portable type electronic product is nickel down-lead substantially, and the conductance of nickel is not high in fact, but the reason that can generally use is its weld strength and stability can reach requirement, and conductance exceedes iron or stainless steel etc. after all.And from the words that conductance is considered, copper or silver are optimal selections, but the weld strength of copper or silver and stability low, cause battery because the failure rate of weld strength and stability aspect is too high and instructions for use cannot be met, and the ratio of copper or silver is great, is unfavorable for the lightweight of battery.
Prior art proposes to use aluminum or aluminum alloy as the lead-in wire of this kind of battery, although the light specific gravity of aluminum or aluminum alloy, can adapt to light-weighted requirement, and the conductance of aluminium is also high than nickel, should be good selection, but also there is weld strength and the low problem of stability in aluminum or aluminum alloy.Prior art proposes to improve use aluminum or aluminum alloy lead-in wire, its main technical schemes arranges metal except aluminum or aluminum alloy as connector in the one or both ends of aluminum or aluminum alloy lead-in wire, to be connected with other parts by connector and accept soldering, pad intensity and welding stability can be improved like this, its mainly nickel, iron and stainless steel of the metal or alloy except aluminum or aluminum alloy selected.This improvement opportunity can realize the weight reducing battery lead, but there is serious defect in this technology, this defect is exactly because the metallic conductivity of connector is lower than aluminum or aluminum alloy, therefore can affect the electric discharge of battery and under the long electric power thus supplied of battery, have a large amount of heat generations, the life-span of battery or even electronic product can be affected.
Summary of the invention
The object of this invention is to provide a kind of technical scheme, this technical scheme can in solution battery light-weighted a large amount of generations reducing cell heat simultaneously, and achieve and substitute existing nickel down-lead by the iron of cheaper or ferroalloy lead wire or aluminum or aluminum alloy goes between.
The present invention is achieved by the following technical solutions:
A battery lead for mobile terminal, described lead-in wire is made of metal, and on the surface of lead-in wire or be at least that the face be connected with other parts adopts doping treatment, first described doping treatment is carried out mixing indium process and carried out mixing Copper treatment again; The described thickness mixing indium layer is 50-100 nanometer, described in mix indium amount be every square centimeter of 5-10 milligram; The described thickness mixing layers of copper is 10-50 nanometer, and mixing copper amount is every square centimeter of 40-60 milligram.
Described lead-in wire metal is iron, ferroalloy or stainless steel.
The described thickness mixing layers of copper is 15-40 nanometer, and mixing copper amount is every square centimeter of 40-55 milligram.
Described phone lead-in wire is banded structure.
The present invention's beneficial effect is compared with the existing technology:
Adopt the result of mixing indium process to be that the difference between the resistance of connector and the resistance of copper is reduced, would not cause because resistance difference is excessive like this and produce a large amount of heat.
Adopt the result after mixing Copper treatment to be the increase in the conductance of lead-in wire, and because the raising of conductance and use iron or stainless steel to improve intensity for lead-in wire, thickness and the width of lead-in wire can be reduced, effectively decrease the weight of lead-in wire.
