Description
Technical field
The technology of the present invention category electrochemical technology field.The technology of the present invention product is：Lead-acid accumulator is repaired liquid product and repaiied
Compound method.Product is related to the reparation to lead-acid accumulator.
Background technology
Lead-acid accumulator as most important stabilized power source and dc source, be widely used in aviation, railway, automobile,
The industry-by-industries such as ship, communication, finance, national defence, department.In all kinds of batteries, lead-acid accumulator proportion is maximum, about
The 75% of battery total amount.The social usage amount of the current lead-acid accumulator in China is more than 300,000,000, is also rapidly being increased in recent years.
Lead-acid accumulator (generally 2 years or so), or (battery charges not because of improper use after a certain period of use time
Foot, overcharge, overdischarge, long-term place are not charged), the lead sulfate (PbSO in battery electrolyte4) can separate out again, in electricity
One layer of white of Surface Creation of pond negative plate and hard lead sulfate crystalline solid (also referred to as " sulfation ").Lead sulfate on negative plate
Crystallization has played iris action so that and the active material in negative plate or can not reduce the electrochemical reaction for participating in discharge and recharge, from
And cause the efficiency of battery to reduce, function is lost until scrap.Lead-acid accumulator fails caused by " sulfation ", scrapped
It is most common, generally occur；Lead-acid accumulator efficiency declines, scrapped, wherein more than 85% is all because battery sulfation is made
Into.Lead-acid battery is according to its different quality grade and the industrial and mineral condition used, and the life-span is in 1.5-4.China is at present per annual report
Useless lead-acid accumulator (all size) nearly hundred million.The lead-acid accumulator largely scrapped, wastes the energy and resource, and adding makes
With the cost of unit, also environment is caused seriously to pollute.Waste and old lead acid accumulator is repaired, extends battery,
Whole society's amount of battery consumption is reduced, is that (in October, 2003, country promulgated for the Chinese government《Refuse battery pollution prevention technique policy》,
Encourage, promote the repairing and reusing of old and useless battery), the expert of lead-acid battery industry, engineers and technicians are researching and solving always
Problem and problem；It is the work that there is strategic importance, have great economy and social benefit.
