Abstract
The invention relates to a battery manufacturing method, and in particular relates to a battery evacuating formation method. When a charger (1) charges a battery (3) through a wire (2), a great amount of gas is generated inside the battery to raise sulfuric acid in the battery into an acid pot (4) above the battery, a negative pressure generator (6) generates negative pressure, the acid pot is sucked to negative pressure through a gas pipe (5), and gas in the battery (3) is timely discharged; meanwhile, the sulfuric acid in the acid pot is timely filled into the battery for reaction; during formation of the battery, the battery is evacuated to enable the sulfuric acid to completely penetrate into a lead active material, so that the conversion uniformity of the active material is improved, the formation efficiency is improved, the charging amount is decreased, and the charging time is shortened.
Description
Technical field
The present invention relates to a kind of manufacture processing method of battery, more specifically, relate to a kind of battery vacuum formation method.
Background technology
The principle of electric weight is changed and stored to lead acid accumulator being: lead powder is lead oxide, generate lead sulfate with sulfuric acid infiltration, at positive pole after overcharging, convert brown lead oxide to, negative machine converts porous lead to, the velvet-like porous lead of so anodal brown lead oxide, negative pole, together with sulfuric acid, just forms the battery that can store electric weight.This transfer process is also common " life thing is changed the process of ripe being ".
Shortcoming: because battery can generate heat when charging, produce a large amount of bubbles, this bubble is by the sulfuric acid jack-up of inside battery, acid and plumbous being permeable reactive are insufficient like this, while causing charging, lead powder is much still the state existence of lead oxide, so just hinder the formation efficiency of lead sulfate, also hindered the formation efficiency of brown lead oxide simultaneously.Cause needing a large amount of chargings, need charge for a long time, waste electric weight, has reduced formation efficiency.
Summary of the invention
Technical problem to be solved by this invention is, when battery changes into, battery carried out to exhaust, be beneficial to sulfuric acid completely with plumbous being infiltration, thereby put forward being conversion uniformity, improve formation efficiency, reduce charge volume and charging interval.
The chemical synthesizing method of finding time, described method comprises:
3 stages: the first stage: electric current charges to battery, charge and vacuumize negative pressure Exhaust Gas for 1～3 hour; Second stage: electric current charges to battery, charges and within 23～29 hours, vacuumizes negative pressure Exhaust Gas, and three phases: electric current charges to battery charges and within 9～11 hours, vacuumizes negative pressure Exhaust Gas;
3 stages are the method for charging and vacuumizing, method is: when charger process wire is when charging for battery, inside battery produces a large amount of gas, the sulfuric acid jack-up in battery, top is in the sour kettle of battery top, and negative pressure generator produces negative pressure, by tracheae, on sour kettle, takes out negative pressure, gas in battery is discharged in time, and the sulfuric acid in sour kettle of while is filled in time inside battery and reacts;
Described negative pressure is-0.06～0.085MPa.
The described first stage, the electric current of battery charging is 0.12～0.13 times of battery capacity; Second stage, the electric current of battery charging is 0.205～0.215 times of battery capacity; Phase III, the electric current of battery charging is 0.12～0.13 times of battery capacity.
Beneficial effect:
In charging process, adopt the foam method method of bleeding, by negative pressure, the gas of inside battery is extracted out, sulfuric acid is fully permeated in plumbous being, so just aggravate the speed of lead oxide generation lead sulfate, also further aggravate lead sulfate and convert brown lead oxide speed to, thereby reduce 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%.The active conversion uniformity improves in Table 1, and battery life situation is in Table 2.
