Description
Technical field
The present invention relates to Lead-acid Battery Technology field, be specifically related to a kind of power type accumulator battery and suppress hydrogen precipitation agent.
Background technology
Lead accumulator is in charging process, as 90% PbSO
4be reduced to after active material spongy lead, start to have hydrogen to separate out; But when the impurity that the overpotential that has hydrogen on electrolyte or negative electrode active material is low (antimony, copper, iron etc.), hydrogen can be separated out in advance, makes the hydrogen amount of separating out of battery sharply increase.
The positive grid of power type accumulator battery adopts lead-antimony alloy, long-term discharge and recharge use procedure in anodal antimony constantly move on electrolyte and negative pole, cause cell with hydrogen air elutriation output to increase.Power type accumulator battery, due to special environment for use and service condition, requires to have low hydrogen-separating quantity and guarantees the security performance using.
For reducing the hydrogen amount of separating out of battery, mainly adopt at present two kinds of methods both at home and abroad.One is to adopt the positive grid of low antimony alloy manufacture, reduces the antimony content in battery; Be to add the retardant that the hydrogen such as humic acid, sodium lignosulfonate are separated out at negative electrode active material, reduce battery the separating out of hydrogen in charging process.These two kinds of methods have reduced the hydrogen amount of separating out in early stage in power type accumulator battery life-span and mid-term to a certain extent, but separating out in a large number without effective inhibitory action for battery later stage hydrogen.
Summary of the invention
The problem of separating out in a large number for solving power type accumulator battery later stage hydrogen, the invention provides a kind of power type accumulator battery and suppresses hydrogen precipitation agent, and the present invention has reduced the hydrogen amount of separating out of storage battery, has improved lead acid accumulator job security in closed environment; The present invention does not affect the capacity of battery, efficiently solves the self discharge problem of battery, the life-span of having improved battery simultaneously.
Power type accumulator battery of the present invention suppresses hydrogen precipitation agent, is made up of inorganic additive and organic additive, and wherein: inorganic additive is cerous sulfate and cadmium sulfate, organic additive is at least one in betanaphthol or vanillic aldehyde.
Wherein: the weight ratio of inorganic additive and organic additive is 10～35:60～85.
It is upper that organic additive in the present invention can be adsorbed on the particle (antimony) that negative pole liberation of hydrogen overpotential is low, thereby reduce separating out of hydrogen; In the present invention, inorganic additive is spread and is arrived battery cathode surface by electrolyte, improves the overpotential that hydrogen is separated out on negative pole, has suppressed separating out of hydrogen.Additive of the present invention is separated out two kinds of effects of overpotential by the suction-operated of organic additive with raising negative pole hydrogen and is interosculated, and effectively reduces the hydrogen amount of separating out of power type accumulator battery.
When use, power type accumulator battery of the present invention is suppressed to hydrogen precipitation agent to be dissolved in dilute sulfuric acid, then join in electrolyte, addition is 1 of electrolyte quality～20 ‰, can reach and reduce by 35% effect of cell with hydrogen air elutriation output and have the advantages that effect is lasting, can continue 19 supposition cycles, actual use more than 4 months.The present invention have consumption few (as long as adding 1 of electrolyte quality～20 ‰), effect obviously (can reduce cell with hydrogen air elutriation output 35%), effect is lasting (continues 19 supposition cycles, actual use more than 4 months) effect, be a kind of compound inhibition hydrogen precipitation agent that can greatly reduce the power type accumulator battery hydrogen amount of separating out.
The present invention has following three kinds of prioritization schemes:
Power accumulator of the present invention suppresses hydrogen and separates out additive, is made up of the raw material of following parts by weight: 60～75 parts of 3～15 parts of cerous sulfates, 5～20 parts of cadmium sulfates and vanillic aldehydes.
Power accumulator of the present invention suppresses hydrogen and separates out additive, is made up of the raw material of following parts by weight: 50～70 parts of 3～20 parts of cerous sulfates, 5～25 parts of cadmium sulfates and betanaphthols.
Power accumulator of the present invention suppresses hydrogen and separates out additive, is made up of the raw material of following parts by weight: 30～45 parts of 3～15 parts of cerous sulfates, 5～20 parts of cadmium sulfates, 15～30 parts of betanaphthols and vanillic aldehydes.In power type accumulator battery, use this composition to suppress hydrogen and separate out additive, the hydrogen amount of separating out reduces more obvious, suppresses liberation of hydrogen longer effective time.
In sum, the present invention has the following advantages:
(1) in the present invention, organic additive can be adsorbed on the particle that negative pole liberation of hydrogen overpotential is low, thereby reduces separating out of hydrogen; Inorganic additive has improved the overpotential that hydrogen is separated out at negative pole, has suppressed separating out of hydrogen.
(2) the present invention have consumption few (as long as adding 1 of electrolyte quality～20 ‰), effect obviously (can reduce cell with hydrogen air elutriation output 35%), effect is lasting (continues 19 supposition cycles, actual use more than 4 months) advantage, be a kind of compound inhibition hydrogen precipitation agent that can greatly reduce the power type accumulator battery hydrogen amount of separating out.
(3) the present invention has reduced the hydrogen amount of separating out of storage battery, has improved lead acid accumulator job security in closed environment; The present invention does not affect the capacity of battery, efficiently solves the self discharge problem of battery simultaneously.
