Abstract
The utility model relates to a steel strip for manufacturing a high-magnification cadmium-nickel alkaline bag type battery plate. A plurality of circular holes which are uniformly distributed are punched on the steel strip, wherein hole density is larger than 500 per square centimeter, and hole ratio is above 25%. The steel strip for the high-magnification cadmium-nickel battery plate can satisfy requirements to plates when high-magnification cadmium-nickel batteries are manufactured. The discharge time of the batteries made by the utility model can achieve 8 minutes, and the discharge capacity of the batteries can achieve 5C5A; compared with sintering type high-magnification cadmium-nickel batteries, the cost of the utility model is reduced by nearly one half.
Description
The utility model relates to a kind of steel band that is used to make high magnification cadmium-nickel alkaline bag-type battery pole plate.
The pole plate of cadmium nickel bag-type battery steel band commonly used is made.Pouch or box-like is made at first punching on steel band then, more Powdered or sheet active material is put in wherein, at last mouth is sealed up, and promptly can be made into pole plate.By the intensive aperture on the pole plate, active material contacts with the electrolyte of submergence pole plate, and electrochemical reaction takes place, thereby produces electric current.The effective area difference of electrochemical reaction then takes place in the height difference of hole density and porosity on the steel band on the pole plate, cause the height difference of discharge-rate.Hole density and porosity are high more, and discharge-rate is high more.So-called hole density, the i.e. quantity of the aperture on every square centimeter the steel band.So-called porosity, the i.e. percentage of the aperture area numerical value sum on every square centimeter the steel band.So-called discharge-rate, promptly rate of discharge is numerically equal to the multiple of this battery rated capacity.At present, the punching hole type ickel-cadmium cell has only low range and two kinds of specifications of moderate multiplying factor, and does not have the high magnification specification.Its one of the main reasons is that hole density and the porosity on the steel band is lower.For example, the hole density of low range bag-type battery is approximately 200/square centimeter, and porosity is 10～14%.The hole density of moderate multiplying factor bag-type battery is approximately 400/square centimeter, and porosity is 20～22%.And the cost of slug type Cadmium Batteries with High Discharge Rate is higher, seldom is used.Therefore caused the shortage of high magnification pocket type ickel-cadmium cell.
It is lower that the purpose of this utility model provides a kind of cost, and be suitable for making the steel band of Cadmium Batteries with High Discharge Rate pole plate.
In order to achieve the above object, the utility model adopts suitable hole-punching method, and the hole density on the steel band is brought up to more than 500/square centimeter, and porosity is brought up to more than 25%.
Below in conjunction with specific embodiment the utility model Cadmium Batteries with High Discharge Rate pole plate steel band is described in further detail.
Fig. 1 is the structural representation of the utility model Cadmium Batteries with High Discharge Rate pole plate steel band.
With reference to figure 1 the utility model Cadmium Batteries with High Discharge Rate pole plate steel band 1 upper punch most equally distributed apertures 2 are arranged, aperture 2 is rounded.Pore density is greater than 500/square centimeter, and porosity is more than 25%.Because the hole density and the porosity of steel band 1 are higher, with the effective area of its battery pole plates of making greater than in, the pole plate of low range battery, be suitable for the high magnification heavy-current discharge.
This Cadmium Batteries with High Discharge Rate pole plate steel band can satisfy when making Cadmium Batteries with High Discharge Rate the requirement to pole plate.After tested, the battery discharge time made from this steel band has surpassed international IEC standard (5 minutes), can reach 8 minutes, and discharge capacity can reach 5C
5A.Compare with the slug type Cadmium Batteries with High Discharge Rate with its battery of making, cost almost will reduce half.
