Abstract
This electrolytic solution for lead accumulator consists of thin sulfuric acid, active carbon, cadimium sulfate and cobalt sulfate, whose weight percentage is: 98-99.8% of thin sulfuric acid of 1.28g/cm.cube of specific gravity, 0.05-0.8% of active carbon, 0.03-1.0% of cadmium sulfate and 0.02-0.6% of cobalt sulfate. The electrolytic solution can inhibit, delay and eliminate the vulcanizing of accumulator polar-plate; enlarge and recover its capacity, prolong its service-life, raise its out-put power and shorten its charging time, prolong its leave-with and storing time after being charged and can be used for emergency by stimulating its active material.
Description
The present invention relates to a kind of electrolyte that is used for lead accumulator.
At present, in the lead accumulator used common electrolyte generally to adopt proportion be .24～1.28 gram per centimeters
3Sulfuric acid solution, use this electrolyte, pole plate easily vulcanizes, the storage battery internal resistance is increased, and the storage battery capacity reduces, and the charging interval prolongs, vulcanize and storage battery is scrapped when serious, and plate vulcanizing be difficult to be eliminated with conventional method, so, generally use to be half a year to one year in useful life of the storage battery of common electrolyte.
The objective of the invention is to overcome the existing existing defective of battery liquid, providing a kind of improves and recovers battery capacity, can suppress to delay and eliminate accumulator plate sulfuration, can prolong the useful life of storage battery, can shorten the charging interval of storage battery, save electric energy, widen battery temp accommodation, reduce accumulator internal resistance, strengthen power output, shelve the time of depositing after increasing charge in batteries, excite the storage battery active material to guarantee the emergent high-efficiency electrolytic solution that uses.
High-efficiency electrolytic solution of the present invention is made up of dilute sulfuric acid, active carbon, cadmium sulfate and cobaltous sulfate, and the percentage of its each composition weight is: proportion is 1.28 gram per centimeters
3, dilute sulfuric acid 9.8～99.8%, active carbon 0.05～0.8%, cadmium sulfate 0.03～1.0%, cobaltous sulfate 0.02～0.6%.
The manufacture method of this high-efficiency electrolytic solution is to prepare burden according to the above ratio, promptly obtains finished product after stirring.
The present invention compares with existing lead storage battery electrolytic solution, has the following advantages:
1, can improve and recover the capacity of storage battery,, can reach rapidly or, capacity is reduced bigger storage battery, can recover its capacity greater than rated capacity to not reaching the new accumulator of rated capacity.
2, can prolong the useful life of storage battery,, thereby under the condition of normal use, can prolong storage battery useful life 50～200% because electrolyte of the present invention can suppress, eliminate plate vulcanizing.
3, can make serious sulfuration and the storage battery " regenerating reactivating " scrapped, in waste battery, add this electrolyte after, once charging generally can reach about 50% of rated capacity.
4, can strengthen the battery power output, new and old storage battery no matter, add electrolyte of the present invention after internal resistance obviously reduce, thereby reduce the internal resistance loss, the storage battery power output is obviously increased.
5, can shorten the charge in batteries time, amount of electricity saving can reach more than 14%.
6, can increase shelving the resting period behind the charge in batteries, not enough and the storage battery of electric leakage is arranged to depositing electricity, add this electrolyte after, left standstill 5～20 minutes, can excite the storage battery active material, self-increase capacity guarantees emergent the use.
7, battery temp accommodation be can widen, storage battery normal power supply and charging under environment in freezing winter and in sultry summer guaranteed.
8, electrolyte temperature is 2～3 ℃ in the time of can reducing charging, is beneficial to protect pole plate.
9, the pernicious gas in the time of can alleviating charge in batteries significantly pollutes.
Below in conjunction with embodiment the present invention is described in more detail.
