Description
Technical field
The present invention relates to nickel-hydrogen secondary cell and assembly method, be specifically related to low capacity nickel-hydrogen secondary battery and assembly method.
Background technology
Ni-MH battery is that domestic and international in recent years a kind of alkalescence of research and development energetically can be filled secondary cell.Use more and more widely in fields such as communication and digital product, electric tool, instrument and meter, toy model plane, electric automobiles now.Its form and requirement are also more and more diversified, and the factor that influences the Ni-MH battery performance has a lot, comprise battery just/many aspects such as the granularity of the base material of negative plate, the kind of hydrogen-storage alloy, active material, the classification of additive and quantity and electrolyte, barrier film, chemical synthesis technology.
The assembling of low-capacity batteries at present mainly contains two kinds of schemes: 1. the height that increases utmost point group by the area that increases the both positive and negative polarity matrix; 2. the both positive and negative polarity of low-capacity batteries uses long ear-pole; These two kinds of methods mainly have the following disadvantages: the price of the matrix foaming nickel of scheme 1, positive plate and the matrix copper mesh of negative plate is not low, the cost of low-capacity batteries is too high like this, more caused the waste of resource, and the elasticity of assembling also is very restricted, utmost point group volume also deforms easily, under vibration condition, utmost point group is shifted up and down and becomes flexible, and the hidden danger of battery short circuit and blast is arranged; Scheme 2, the ohmic internal resistance that has increased battery and polarization resistance have reduced the battery multiplying power discharging property, and the electrode of charge and discharge process expands more obvious, and the super-charge super-discharge performance of battery also is subjected to very big influence.
Summary of the invention
The objective of the invention is to: a kind of low capacity nickel-hydrogen secondary battery and assembly method are provided, and assembly method is succinctly convenient, can reduce the low capacity nickel-hydrogen secondary battery cost by this assembly method, and improves the low performance of holding nickel-hydrogen secondary cell.
Technical solution of the present invention is: this low-capacity batteries comprises box hat and utmost point group, and utmost point group is installed in the box hat, and described utmost point group is made up of positive pole, negative pole, barrier film, it is characterized in that: end liner is installed in the bottom of box hat.
The assembly method of low-capacity batteries of the present invention may further comprise the steps: 1, dress box hat: box hat is pressed regularly placing in material box good, and faucal is upwards laid out end liner again on box hat, with instrument end liner shifted onto the box hat bottom;
2, rear end assembling: the utmost point group of winding is put into the box hat that step 1 is put end liner well, roll ditch, gluing, spot welding, notes alkali again, seal assembly process;
3, high temperature is shelved: the battery that assembles in the step 2 is carried out high temperature shelve, this battery is different from general battery when shelving, and need place the battery head downwards, can make alkali lye soak into utmost point group like this;
4, change into: the high temperature of process step 3 is shelved after 48 hours and is changed into.
The end liner that stops utmost point group volume to deform is set in the battery steel shell of the present invention, realize the thickness thin typeization and the high assembling elasticity of positive and negative plate, reduce the ohmic internal resistance and the polarization resistance of battery, improve the battery multiplying power discharging property, suppress the expansion of the electrode of charge and discharge process, guarantee that battery performance is stable, and under vibration condition, the controllable poles group is shifted up and down and becomes flexible, and eliminates battery short circuit and hidden peril of explosion.
