Description

A kind of plating contains the steel band of the multi-layer compound film of nano wire
Technical field
The utility model relates to the steel band that a kind of plating that is used for battery container has the multi-layer compound film that contains nano wire.
Background technology
In recent years, along with people are more and more higher to the requirement of battery performance, the performance of the case material of batteries such as alkaline Mn cell, Ni-MH battery and lithium-ion-power cell also more and more receives numerous professional persons' concern.The alkaline Mn cell shell is as the container of a sealing, because the filling of strong basicity electrolyte requires it that enough strong decay resistance is arranged.In addition, battery case also serves as battery plus plate current-collecting body in alkaline Mn cell, so the internal resistance of battery case also is a key factor that influences battery performance.In addition, battery case also will participate in the reaction of alkaline electrolyte.
Disclose a kind of process for treating surface of battery case steel plate among the patent ZL97198580.4, electroplated one deck nickel at steel plate corresponding to a side that forms the battery container inwall, and then electroplated one deck tin layer, annealing at last forms the nickel-tin alloy layer at the battery inwall.The nickel-tin alloy layer is applied to the inwall of battery container, can effectively reduce the internal resistance of battery container, but after itself and the alkaline matter Long contact time, discharge performance can variation.
Patent CN1600904A discloses a kind of nickel-plated deeply-draw steel strip and production method thereof, continuous electroplating 2~3 μ m nickel coatings on mild-carbon steel strip, handle by heat treatment and laser-impact, make nickel coating and base material form nickel/iron diffusion layer, obtain the corrosion-resistant steel band of required size then by finishing procedure by thermal diffusion.The coating percentage elongation is not less than 8%, and decay resistance reaches 8 grades, has good elongation and decay resistance, is mainly used in the heavy-duty battery sheathing material.But single nickel coating is easy to occur powder phenomenon-tion in the punch forming process of battery case, can increase the defective of battery case sidewall, shortens the life-span of mould and drift.
A kind of surface of steel plate treatment technology at the inside and outside wall plating of battery container nickel-cobalt alloy is disclosed among the patent ZL97194368.0.Because traditional single nickel coating powder phenomenon-tion in the punch forming process of battery container is serious, cause battery container sidewall defective to increase, drift and die life shorten, and production efficiency reduces, and replace single nickel coating then can reduce powder phenomenon-tion significantly with nickel-cobalt alloy.But the hardness of nickel-cobalt alloy coating is very big, be generally HV310 ± 10, and the hardness of mild steel substrate commonly used is HV120 ± 10, coating and substrate hardness differ too big, the hardness number mismatch is serious, causes occurring the coating obscission easily in the punch forming process of battery container.
A kind of process for treating surface of battery case steel plate is disclosed among the patent ZL99809927.9, electroplate one deck nickel at steel plate corresponding to a side that forms the battery case inwall, and then electroplate one deck bismuth layer, last annealing in process forms nickel-bismuth alloy layer in the battery inner walls.After bismuth metal and the alkaline solution Long contact time, electrodeposited coating can not dissolve, but bismuth coating comes off easily, and the phenomenon that nickel-bismuth alloy can not occur coming off.Nickel-bismuth alloy layer is applied to the inwall of battery container, can obviously improve the decay resistance of battery container in alkaline environment.But the electric conductivity of bismuth is very poor, the application of nickel-bismuth alloy, the internal resistance that has increased the battery container inwall.
Zhang Xian, people such as Xu Yijun mention in " performance of the alkaline Mn cell of box hat electroplated Ni (Bi) and annealing in process " literary composition, nickel coating has stronger adhesion property and decay resistance on the box hat surface, but it is relatively poor with the contact performance of anode ring, nickel-phosphorus, nickel-tin alloy can improve contact performance, but decay resistance is relatively poor.Bismuth is stable in alkaline solution, and is good with the contact performance of positive electrode active materials EMD, and heating condition diffusion easily down, is easy to form alloy.Also mention in the literary composition, annealing can increase the internal resistance of nickel coating, and because the formation of nickel-ferro alloy, nickel coating thickness descends, and causes the contact performance of box hat and anode ring and decay resistance to descend.
Patent CN101311330C discloses a kind of nickel composite film that is composited by one dimension nickel nano wire and two-dimentional nickel film and preparation method thereof.This nickel composite film has good mechanical performance and processing characteristics, can resist bigger shock loading, and have with low cost, advantage of simple technology.
Because steel band top layer coating requires to have higher hardness, thus the high metal or alloy coating of hardness generally adopted, and adopt a series of technology to make prepared top layer coating have less crystallite dimension, the coating densification.Yet such coating often has higher internal stress, can reduce the toughness of coating like this, causes brittle coating.
Well behaved alkaline battery has the requirement of comparison harshness to its case material.Because the strong basicity electrolyte of alkaline battery is filled, therefore require case material that good alkali corrosion resistance performance is arranged.Battery container requires it to have lower internal resistance as plus plate current-collecting body, and can the excellent contact performance be arranged with positive electrode material, and this has electrical conductivity preferably with regard to the case material that requires to make battery, and the surface hardness height.Why want case material to have higher surface hardness, be because the high material of surface hardness forms trickle crackle at the battery container inwall easily in battery punch forming process, be equivalent to increase the contact area of battery container and positive electrode material, improved the contact performance of battery container and positive electrode material, simultaneously, the crackle that is produced has good lubricant retentivity, makes the housing demoulding more easy.Battery container is very big in the deformation drag of punching course, if when the adhesion of coating and substrate is bad, is easy to occur the phenomenon that coating comes off.In addition, if when the powder performance of coating is relatively poor, promptly coating forms more powder in the ironing process, and these powder adherence can cause defective to the battery case sidewall on drift.
The process for treating surface of existing battery container steel band all is single nickel coating or duplicature design simple in structure.The shortcoming of these technology is that when possessing some advantage, also there are some shortcomings bigger to the battery container performance impact in after treatment steel band.For example, traditional nickel plated steel strip, its corrosion resistance and good combines well with substrate, but its powder performance is relatively poor, promptly forms powder in punching course easily.The steel band of plated nickel and nickel-cobalt alloy because the hardness of nickel-cobalt alloy is big, causes the hardness number of coating and substrate not match, occurring coating in punching course easily comes off, the coating that hardness is high often has higher internal stress in addition, can reduce the toughness of coating like this, causes brittle coating.The steel band of plated nickel and nickel-bismuth alloy, its alkali corrosion resistance performance is good, but because the poorly conductive of bismuth causes the internal resistance of battery container big.The steel band of plated nickel and nickel-tin alloy, its internal resistance is little, but because the alkali corrosion resistance poor performance of nickel-tin alloy, after battery container and alkaline electrolyte Long contact time, the guiding discharge degradation.
The utility model content
