Description
Technical field
The present invention relates to field of cell preparation more particularly to a kind of efficient formation methods of 20Ah lead-acid accumulators.
Background technology
Electric bicycle is very universal in recent years, and main power source is lead-acid accumulator, lead-acid accumulator master
It will be there are two types of formation regime：One is battery tank formation, plates polarizing is subjected to supplement electricity at being assembled into after battery, another kind is electricity
Pond is internalized into, then green plate direct-assembling is melted into again at finished battery；And tank formation than be internalized into discharge acid solution,
Sewage and dust are all more, seriously pollute environment, therefore internal formation process has certain advantage.
Application No. is 201410541611.7 Chinese patents to disclose a kind of lead-acid accumulator multistage charge and discharge internalization
At technique, which can not only be shortened the formation charging time of battery and be reduced monolithic pole plate pair using multistage charging and discharging
The consumption of electricity reduces energy consumption, and reduces the production cost of product.But the technique used time needs 3 days, the time is longer,
Energy consumption is higher, and formation effect is slightly worse.
Invention content
In order to solve the above technical problem, the present invention provides a kind of efficient formation method of 20Ah lead-acid accumulators,
By adjusting charge and discharge time, order and the size of current at container formation initial stage, 20Ah lead-acid accumulators is enabled to be internalized into effect
Good, the required chemical conversion time is short, at low cost, is suitable for actual industrial production.
The specific technical solution of the present invention is：The method includes the steps of：
1) 1-1.5h will be stood after 20Ah lead-acid accumulator acid addings；
2) battery is with the electric current constant-current charge 1-2h of 1A；
3) battery is with the electric current constant-current charge 1.5-2h of 2A；
4) battery is with the electric current constant-current charge 3-3.5h of 3A；
5) battery is with the electric current constant-current charge 7-7.5h of 5A；
6) battery is with the electric current constant-current charge 6-6.5h of 2.5A；
7) battery is with the electric current constant-current discharge 1-2h of 3A；
8) battery is with the electric current constant-current charge 2h of 3.7A；
9) battery distinguishes constant-current charge and/or electric discharge several times with the electric current of 0-10A, every time charging and/or discharge time
0.25-4h。
The density of electrolyte when electrolyte of injection is battery normal use, nothing needs to change electrolyte, but is electrolysed liquid-tight
Degree is high, and chemical conversion difficulty is big, needs more time and electricity；When chemical conversion starts, active material is occupied the majority with lead sulfate in pole plate,
Lead sulfate is non-conductor, big with grid contact resistance, chemical conversion product just extremely PbO2, cathode Pb, positive plate electric conductivity
It is all poor in long period early period；Chemical conversion charging current early period is small, in short-term after low current charge, pole plate charge acceptance
By force, charging current can be increased, it is small that battery generates heat；Be melted into mid-term, battery charge acceptance decline, battery terminal voltage by
Gradually rise, charging side reaction increases, and temperature, which rises, to be increased, and charge efficiency declines, and is charged using moderate current densities；It is melted into later stage, electricity
It is poor to flow ability to accept, current density requires smaller.Also studies have found that electric discharge is added in charging, charging can be improved by energy
Power improves charge efficiency, reduces the charging time, reduces charge volume.
But the selection of size of current, the factors such as the order of charge and discharge and the duration of charge and discharge to the Battery formation time and
There are no unified rules for the influence of battery performance, and are interfered with each other between these factors, and the present invention is stored for 20Ah plumbic acids
Battery, according to many years of experience, adjusts charge and discharge time, order and the size of current at container formation initial stage by largely attempting,
Time control is melted within 2 days, formation effect is good, at low cost, and gained battery performance is good.
Preferably, the density of electrolyte that lead-acid accumulator is added in the step 1) is 1.250g/cm3。
Preferably, single lattice acid content is 214ml/ single lattices in lead-acid accumulator in the step 1).
Preferably, the step 2) -9) in battery be in water bath, 30-40 DEG C of bath temperature, internal temperature of battery
≤55℃。
Being melted into temperature height, then formation efficiency is high, but is easy to happen decomposition, corrosion, and the low then efficiency of chemical conversion temperature is low, still
Battery performance is not interfered with, therefore bath temperature is maintained at 30-40 DEG C by the present invention, formation efficiency is moderate, internal temperature of battery
≤ 55 DEG C, prevent cell damage.
Preferably, the step 2) -9) in charging and discharging currents error within ± 0.01A.
Influence of the size of electric current to formation effect is very big, therefore error preferably must be held within ± 0.01A.
Preferably, the step 2) -9) in battery pregnant solution kettle in single lattice acid amount liquid level it is consistent.
Acid deficient phenomenon is not may occur in which in battery forming process, therefore single lattice acid amount liquid level is consistent in the pregnant solution kettle of battery.
Preferably, charging and/or discharge time are 22 times in the step 9).
It is compared with the prior art, the beneficial effects of the invention are as follows：The present invention is directed to 20Ah lead-acid accumulators, by largely tasting
Examination adjusts charge and discharge time, order and the size of current at container formation initial stage according to many years of experience, is melted into time control
System is within 2 days, and formation effect is good, at low cost, and gained battery performance is good.
