As compared with existing technique, the cell capacity, low-temperature start property and circulating life of a storage cell using the invention are increased at least by 20% and those of some cell by 150%, it improves the charge accepting ability of storage cell, can completely charge the storage cell at lower charge voltage, eliminates electrolyte segregation, reduces the sulfation of polar plates, prolongs the service life of the storage cell under adverse circumstances (high temperature and low temperature), and the use temperature range of the novel electrolyte is -40 deg.C-70 deg.C and broader than that of an ordinary electrolyte.
Description
The present invention relates to a kind of lead-acid battery electrolyte.
The used electrolyte of existing lead acid accumulator mainly is made up of sulfuric acid and water, and its shortcoming is the not enough and consumption in use of battery terminal negative organic expander performance, has influenced the starting capability and the cycle life of storage battery; And sulfuric acid is to the dissolving of stereotype, and pole plate is fast by sulfation, dividing plate is penetrated soon, and battery life is short; Because the overpotential of hydrogen evolution of negative pole can only could charge battery fully under higher charging voltage, the charge acceptance of storage battery is low, the easy layering of electrolyte.
The present invention solves the above-mentioned problems in the prior art exactly, and a kind of novel electrolyte is provided, and the storage battery cold-starting ability that adds this electrolyte is strong, have extended cycle life, and eliminates electrolyte stratification, reduces polar plate sulfation.
For addressing the above problem, technical solution of the present invention is: a kind of novel electrolyte, by weight calculating, it comprises 36～39% sulfuric acid, 54～64% purify waste water, 0.01～1% sodium lignosulfonate, 0.05～5% anhydrous sodium sulfate and 0.0001～1% seven water nickelous sulfates; With sulfuric acid, purify waste water, anhydrous sodium sulfate and seven water nickelous sulfates are being not more than mixing and stirring under 70 ℃ the temperature by above proportioning, treat that temperature is not reduced to when being higher than 35 ℃ and use, in each single lattice of battery, add sodium lignosulfonate by above proportioning, add the temperature that configures again and be not higher than 35 ℃ above liquid, perhaps in each single lattice of battery, add the temperature that configures earlier and be not higher than 35 ℃ above liquid, add sodium lignosulfonate by above proportioning again, leave standstill and entrucking to use in 30 minutes.
Because the present invention has adopted such scheme, the adding of sodium lignosulfonate has remedied the deficiency of battery terminal negative organic expander performance and consumption in use, the starting capability and the cycle life of storage battery have been improved, along with the storage battery prolongation of service time, the storage battery that liquid injection port is arranged, sodium lignosulfonate can also continue to add to improve the performance and the useful life of battery.The adding of anhydrous sodium sulfate, because the common-ion effect of electrolyte, the dissolving of lead sulfate reduces, and can suppress the sulfation of pole plate and penetrating of dividing plate, improves battery useful life.The adding of seven water nickelous sulfates has reduced the overpotential of hydrogen evolution of negative pole, battery just can be charged under lower charging voltage fully, improved the charge acceptance of storage battery, under the situation of constant voltage charge, produce more bubble, agitate electrolyte, thereby eliminate electrolyte stratification, and can not cause the increase of damage by water consumption by the seven water nickelous sulfates that the present invention uses.From the contrast experiment, can find out, use storage battery of the present invention, the minimum raising 20% of its battery capacity, cold-starting ability and cycle life, the cycle life of the battery that has has improved 150%.Improve the useful life of storage battery under adverse circumstances (high temperature, low temperature).Electrolyte temperature scope in the battery use is-40 ℃～70 ℃, and is wideer than the temperature range that common electrolyte uses.
Below in conjunction with specific embodiment the present invention is described in further detail.
