At present, the main recovery technique of lead acid accumulator comprises and adding containing K
+, Na
+the alkali metal ion of class, or Al
3+, Ca
2 +, Fe
2+etc. active metal ion, be partly dissolved lead sulfate.But such renovation agent also has dissolution to lead, reduce pole plate mechanical strength, accelerate active material on pole plate and come off.In addition, also can add hydrophily functional high molecule material, have solid state surface material and extremely strong sprawl penetrating power, after it is injected into lead-acid battery inside, disperse rapidly by inner sulfate liquid system, the lead sulfate crystallization Interacton of Cluster on macromolecular chain functional group and negative plate top layer, its result is that negative plate salinization cluster is progressively disintegrated, top layer iris action is destroyed, by implementing battery capacity just can be made to be restored to the charging again of battery, but use this method likely to increase the internal resistance of cell, cause the problem that after repairing, the operating period is shorter.
Summary of the invention
In order to solve the problem in lead acid accumulator reparation, the invention provides a kind of lead acid accumulator and repairing reducing agent.
