Abstract
A kind of silicon electrolyte of lead accumulator and manufacture method thereof.Silicon solid electrolyte of the present invention is made of A agent and the B agent through purified treatment, and the A agent contains the molten wrist of silicon, water and cleanser; The B agent contains bright sulfur acid, water and cleanser.When storage battery used, A agent and B agent mixed adding by a certain percentage and get final product.Battery capacity is improved more than 20%, increase the service life one times to end, voltage is stable, and self discharge is slow, and Maintenance free still can keep heavy-current discharge at-50 ℃ of low temperature.
Description
The invention belongs to field of chemical power source, a kind of silicon electrolyte of lead accumulator and manufacture method thereof.
Well-known colloidal electrolyte, constitute by sulfuric acid, distilled water and sulfuric acid solidifier, because sulfuric acid solidifier has dissolved into a large amount of chloride ions in process of production, when mixing with sulfuric acid solution, chloride ion reaction in hydrogen ion in the acid solution and the solid agent generates the hydrogen chloride gas evacuator body, causes lacking of electrolyte cation.When acid solution is mixed with coagulating agent simultaneously, also lose a large amount of negative ions, make the capacity of storage battery reduce the lost of life.
One of purpose of the present invention is: provide a kind of lead accumulator capacity that makes to improve the silicon solid electrolyte of life-span prolongation, Maintenance free.
Another object of the present invention is: provide that a kind of manufacturing is simple, raw material is easy to get, and is with low cost, the manufacture method of the silicon solid electrolyte of superior performance.
Say that generally silicon solid electrolyte of the present invention is made of A agent and B agent.Described A agent contains Ludox, deionized water (or distilled water), cleanser.Described B agent contains bright sulfur acid, deionized water (or distilled water), cleanser.
Further, the manufacture method of silicon solid electrolyte of the present invention may further comprise the steps:
A, the cleanser of trace is joined in the deionized water (or distilled water), stir, standby.
B, Ludox added contain in the aqueous solution of cleanser, stir, after purifying, contain out standby.(being called for short the A agent)
C, bright sulfur acid is slowly joined in the above aqueous solution that contains cleanser, constantly stir, after purifying, contain out standby.(being called for short the B agent)
When d, curing, A agent and B agent mix and get final product.
In the Ludox of purified treatment, removed the impurity such as iron ion harmful, also removed objectionable impurities such as iron, manganese, arsenic, also increased the number of negative ions simultaneously, made electrolytical ion stabilized through the sulfuric acid solution of purified treatment to storage battery.Exempted the infringement of objectionable impurities, thereby improved the capacity of storage battery, prolonged the useful life of storage battery battery.

The present invention can also make the storage battery self discharge slow, and the energy conversion efficiency height still can keep heavy-current discharge under-50 ℃ low temperature environment, and Maintenance free reduces economic cost.The storage battery volume is dwindled, weight saving, cost reduces, and is easy to use.
Objects and advantages of the present invention can obviously be found out in description.
Narrate embodiments of the invention below:
Embodiment:
The preparation of A agent: the HBr aqueous solution 1.5-2.5KL that gets content 5%, the deionized water for stirring that joins 100KL is even, get pH value and be 20% Ludox 100KL for 7.5-9.5 content, add and contain in the aqueous solution of HBr, fully stir, mix, left standstill 12 hours, then with standby in the pure liquid splendid attire plastics kettle of top, obtain being about that 199.5KL contains silica 1 0%, density is the A agent of 1.050-1.100.The purification temperature of A agent must be controlled at about 20 ℃.
The preparation of B agent: get content and be 3% H
2S solution 5KL joins in the deionized water of 100KL, stirs.Get content again and be 98% or 92% bright sulfur acid 95KL, bright sulfur acid is slowly added under constantly stirring contain H
2In the aqueous solution of S, fully stir, treat that heat radiation is cooled to below 20 ℃, and transfer that to survey density be 1.400-1.600, left standstill 12 hours, with standby in the pure liquid splendid attire plastics kettle, obtain the B agent of about 182KL then.The bright sulfur acid of B agent and the proportional control of the aqueous solution are in (0.6～1.00): 1.(amount meter by volume)
When holding storage battery, the A agent is placed B agent (not turn-overing), fully stirred 30 seconds-1 minute, add in the storage battery, after the placement cooling, electrolyte promptly solidifies.
When preparation density is equivalent to 1.280 electrolyte, get A:B=1:(1-2), when preparation density is equivalent to 1.210 electrolyte, get A:B=1:1.
Silicon solid electrolyte electrochemistry overall reaction equation in storage battery is:
The anodal negative pole silicon of negative pole silicon solid electrolyte solid electrolyte, positive pole
