Description

Battery evacuates chemical synthesizing method
Technical field
The present invention relates to the manufacture processing method of a kind of battery, more specifically, relate to a kind of battery vacuum formation method.
Background technology
The principle of electricity is changed and stored to lead-acid accumulator being: lead powder is lead oxide, lead sulfate is generated with sulfuric acid infiltration, it is converted into brown lead oxide at positive pole after overcharge, negative machine is converted into porous lead, so positive pole brown lead oxide, negative pole velvet-like porous lead together with sulfuric acid, be formed for storing the battery of electricity.This transfer process is also common " process of the ripe being of life thing conversion ".
Shortcoming: owing to battery can generate heat when charging, produce a large amount of bubble, this bubble is by the sulfuric acid jack-up of inside battery, so acid is insufficient with lead being permeable reactive, when causing charging, lead powder is a lot of or the state in lead oxide exists, thus hinder the formation efficiency of lead sulfate, also counteracts that the formation efficiency of brown lead oxide simultaneously.Cause need to charging in a large number, need to charging for a long time, waste electricity, reduce formation efficiency.
Summary of the invention
The technical problem to be solved is, battery carries out during Battery formation evacuate gas, beneficially sulfuric acid and permeates with lead being completely, thus carry being switching homogeneity, improve formation efficiency, reduce charge volume and charging interval.
A kind of battery evacuates chemical synthesizing method, and described method includes:
In 3 stages: first stage: current versus cell charges, charge and within 1～3 hour, vacuumize negative pressure discharge gas；Second stage: current versus cell charges, charges and within 23～29 hours, vacuumizes negative pressure discharge gas, three phases: current versus cell charges, and charges and within 9～11 hours, vacuumizes negative pressure discharge gas；
3 stages are charging and the method vacuumized, method is: when charger through wire when charging for battery, inside battery produces a large amount of gases, the sulfuric acid jack-up in battery, pushing up in the sour kettle above battery, negative pressure generator produces negative pressure, takes out negative pressure by tracheae on acid kettle, making the gas in battery discharge in time, the sulfuric acid in the sourest kettle is filled into inside battery in time and reacts；
Described negative pressure is-0.06～-0.085MPa.
The described first stage, the electric current of battery charging is battery capacity 0.12～0.13 times；Second stage, the electric current of battery charging is battery capacity 0.205～0.215 times；Phase III, the electric current of battery charging is battery capacity 0.12～0.13 times.
Beneficial effect:
Charging process uses and takes out bubble methods, by negative pressure, the gas of inside battery is extracted out, sulfuric acid is made fully to permeate in lead being, thus aggravation lead oxide generates the speed of lead sulfate, is also further exacerbated by lead sulfate and is converted into brown lead oxide speed, thus reduces charge volume 20%, reduce the charging interval 20%, the battery being conversion uniformity of air-discharging charging improves, and deviation is generally less than 4%, and battery life improves 30%.Activity conversion uniformity raising is shown in Table 1, and battery life situation is shown in Table 2.
Table 1: the being conversion uniformity improves
Table 2: battery life situation
Negative pressure is-0.06～-0.085MPa, and atmospheric pressure is 133.32pa, so being that wearing or featuring stage armour inside battery is pumped into negative pressure state bubble is extracted out, then by atmospheric pressure, acid fracturing is entered in pole plate i.e. battery bottom so that it is lead and acid be fully contacted after reaction thoroughly.
