Abstract
The invention discloses an electrolyte of a nano-colloid storage battery which comprises the following components in parts by weight: 43.0-44.0 parts of sulfuric acid, 54.8-55.8 parts of water, 0.8-1.5 parts of nano-silica, 0.008-0.013 part of surfactant, 0.05-0.10 part of stabilizer, 0.008-0.013 part of additive for resisting internal resistance and 0.02-0.04 part of functional high-polymer materials. Accordingly, the electrolyte of the invention can provide a thorough solution to the problem that an ordinary lead-acid battery is prone to layered sulfuric acid, delay the corrosion and passivation of electrode plates, reduce the self-discharge frequency, ensure the good thixotropic properties and good fluidity after being stirred at a high speed and be favor for pouring; the electrolyte can rapidly permeate into the electrode plates, thus avoiding the difficulty in pouring the electrolyte into the conventional colloid battery and overcoming the disadvantages of non-uniform permeation and proneness to lack electrolyte; and meanwhile, the common problems that the ordinary colloid is prone to hydration and cracking can be automatically fixed through the repeated thixotropy in the charging and discharging process, thus reducing the internal resistance of the battery, greatly prolonging the service life thereof and greatly improving the low-temperature performance and over-discharge restoration capacity thereof.
Description
Technical field
The present invention relates to storage battery, relate in particular to a kind of battery liquid.
Background technology
Storage battery is the energy carrier of electric motor car, and electromobile battery is lead acid accumulator mostly at present, this battery liquid facile hydrolysis, layering; The battery acid amount is few; Battery performance descends fast, and is prone to fill drum during charging, is difficult to satisfy the demand for development of current electric motor car.
Summary of the invention
Technical problem to be solved by this invention provide a kind of contain acidity stable, not aquation, do not chap, the electrolyte of nano-colloid storage battery of the liquid layering that can not produce electrolysis.
For solving the problems of the technologies described above, technical scheme of the present invention is: electrolyte of nano-colloid storage battery comprises weight components:
Sulfuric acid 43.0～44.0;
Water 54.8～55.8;
Nano silicon 0.8～1.5;
Polyvinyl alcohol 0.008～0.013;
Polyacrylamide 0.05～0.10;
Oxynaphthoic acid 0.008～0.013;
O-methoxy benzaldehyde 0.02～0.04.
Said nano silicon is a gel; Said polyvinyl alcohol is a surfactant; Said polyacrylamide is a stabilizer; Said oxynaphthoic acid is anti-internal resistance additive; Said O-methoxy benzaldehyde is a functional high molecule material.
As optimized technical scheme, said electrolyte comprises weight components:
Sulfuric acid 43.6;
Water 55.2;
Nano silicon 1.0;
