Description
Technical field
The invention belongs to field of chemical power source, specifically, is a kind of valve-regulated hermetically sealed colloid electrolyte lead-acid accumulator.
Background technology
At present, valve-regulated completely-sealed lead-acid accumulator is widely used in communication, automobile, ups power, many fields such as electric power vehicle using motor, but, from present technical merit, the valve-regulated completely-sealed lead-acid accumulator of liquid exists certain defective, such as: compare with open type, battery is shorter useful life.Though it is many that the aspect ratio open formulas such as acid, leakage and gas output of climbing at battery have been got well because electrolyte still be a liquid state, so still in various degree exist these problems.In order to overcome these shortcomings that battery exists, many researchers have proposed the notion of colloid storage battery, and promptly the electrolyte in the battery does not use liquid sulfuric acid, contain the solid-state electrolyte of gel formula of quantity sulfuric acid much at one and use.
Use gel formula electrolyte, solve a series of problem with regard to needs, as: between the operating period of several years, how colloid keeps stable and " does not dissociate " under certain electric field strength; Between glue and positive and negative pole plate evenly and the problem of combining closely; The ionic conductivity of glue itself is a series of problems such as interior resistance of battery.For this reason, many researchers have delivered a series of document and patent.
Patent CN 1065557 has invented the colloidal electrolyte of forming with A agent and B agent.The siliceous solution of A agent wherein, deionized water, cleanser; The B agent then contains bright sulfur acid and deionized water and cleanser, has enumerated the cleanser of numerous species in the patent.The inventor shows, utilizes the storage battery self discharge of this colloidal electrolyte perfusion little, the energy transformation ratio height, but under 50 ℃ heavy-current discharge still.
Patent CN 1036479 use purity be the high purity water of 5～15 megaohms to industrial metasilicate with 10～12: 1 weight ratio carries out dissolved dilution after cationic, anionic exchange resin is handled, and adds an amount of pure Na of analysis
2SiO
39H
2O is as stabilizer, makes the pH value reach 12～14 backs and concentrates, and to obtain proportion be 1.075～1.099, contain SiO
2Weight ratio is 11.7～15%, Na
2The O weight ratio is 0.26～0.35%, and the pH value is 12～14 silica gel agent, and the storage battery of manufacturing with this glue can meet national standard.
The report that also has other many this respects, but in general there are some not ideal enough parts in some aspects in these reports,＜1〉a lot of reports are not mentioned the life problems of battery,, have been to use statements such as " life-span are long, capacity is high " even mention life problems yet.Even the life-span is long to be again also to can not check concrete correction data in what embodiment to what degree, capacity height to what degree, contrast points;＜2〉in the embodiment of these reports, mostly be that discharge capacity had met or exceeded national standard after the electrolyte invented with the inventor was made storage battery, battery performance is good.Actually but colloidal electrolyte is well-done, or the pole piece of battery is well-done, or battery to manufacture in the process other technologies good, and make the performance of entire cell improve.All do not relate to this problem in nearly all report;＜3〉in general, the electric conductivity of colloidal electrolyte is than liquid electrolyte difference, and particularly under the low temperature, poor is just more obvious.And the environment for use of battery, a lot of situations are to use at low temperatures, thus weigh an important indicator of colloidal electrolyte quality should be cryogenic property how, but a lot of report does not relate to the problem of this respect.
Summary of the invention
