Abstract
The invention discloses a lead storage battery cathode diachylon containing an ionic liquid additive, which comprises the following components in percentage by weight: 80-83% of lead power, 10-15% of water, 4-10% of sulfuric acid with concentration of 98%, 0.01-0.05% of alkyl imidazole bisulfate ionic liquid, 0.05-0.06% of staple fiber, 0.5-1.5% of superfine barium sulfate, 0.2-0.5% of acetylene black, 0.1-0.3% of lignin and 0.1-0.3% of humic acid. According to the invention, the ionic liquid additives are added into the cathode diachylon so as to effectively improve the electrical conductivity of the cathode plate, prevent the irreversible salinization on the surface of the cathode plate, reduce the internal resistance of the battery and enhance the charge receiving capability of the battery.
Description
Technical field
The invention belongs to chemical power source associated materials field, be specifically related to a kind of cathode lead plaster prescription that can be used for lead accumulator.
Background technology
Negative plate and cathode lead plaster are the key factors that influences the lead-acid battery performance, yet the importance of negative pole often is prone to out in the cold all the time.The deposition of the irreversible lead sulfate in discharge process negative plate surface is to cause the main cause of internal resistance of cell increase, battery heating and ultimate failure.Though can make part of sulfuric acid lead change active material into through the large current charge mode, the big and complex operation of its power consumption.Simultaneously, the inefficacy of negative plate can make positive plate active material can't carry out normal electrochemical reaction, has finally damaged cell integrated performance.Therefore, be necessary to seek conductivity and the microstructure that novel suitable additive improves negative plate, hinder the deposition of big volume sulfate in the discharge process, improve the charge acceptance of battery.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of lead accumulator cathode lead plaster that contains ion liquid addictive is provided,, improve the combination property of negative plate and battery the additive of alkyl imidazole hydrogen sulfate salt ionic liquid as the lead accumulator cathode lead plaster.
The technical scheme that the present invention adopts is: a kind of lead accumulator cathode lead plaster that contains ion liquid addictive, and each compositions in weight percentage comprises: lead powder 80 ~ 83%, water 10 ~ 15%; 98% sulfuric acid 4 ~ 10%, alkyl imidazole hydrogen sulfate salt ionic liquid 0.01% ~ 0.05%, short fiber 0.05 ~ 0.06%; Ultra-fine barium sulfate 0.5 ~ 1.5%; Acetylene black 0.2 ~ 0.5%, lignin 0.1 ~ 0.3%, humic acid 0.1 ~ 0.3%.
As preferably, it is two to replace or three replacements that the ion liquid alkyl of alkyl imidazole hydrogen sulfate salt according to the invention replaces kind, and alkyl carbon number amount is 1 ~ 8, and its occupation mode is that a kind of independent use or multiple mixing are used.
Beneficial effect: the present invention is a lead accumulator cathode lead plaster additive with alkyl imidazole hydrogen sulfate salt ionic liquid; The ion liquid bisulfate ion anion of alkyl imidazole hydrogen sulfate salt can merge with sulfuric acid well mutually, and the alkyl imidazole cation has high conductivity and catalytic action.Ion liquid addictive can effectively improve the conductivity and the microstructure of negative plate, hinders the deposition of big volume sulfate in the discharge process, improves the performances such as charge acceptance of battery.A kind of lead accumulator cathode lead plaster that contains ion liquid addictive according to the invention can be adaptable across various lead acid accumulator products.
