Problems solved by technology

For example, the addition of ionic liquids such as triethylammonium hydrogensulfate and benzylammonium hydrogensulfate can increase the utilization of positive active materials, but to some extent increase the corrosion rate of the plate grid
[0014] To sum up, it is mentioned in the current research at home and abroad that the colloidal electrolyte with good performance can only be obtained by selecting the appropriate type and amount of additives, but these researches have the problems of complex formula, difficult control of formula ratio, and limited improvement of battery performance. , there is no report on how to avoid silica gel sedimentation in battery electrolyte

specific Embodiment approach

[0037] The present invention will be further described below through specific examples, but not limited thereto.

[0038] The raw materials used in the examples are conventional commercially available raw materials or synthesized according to reference methods.

Embodiment 1

[0040] An application of an organosilicon compound as an additive in colloidal storage batteries, the organosilicon compound has the following structure:

[0041] HOSi(CH 3 ) 2 CH 2 CH 2 COOH.

[0042] The specific application steps are as follows:

[0043] The preparation density is 1.27g / cm 3 sulfuric acid solution, according to the general formula of the industry, add common additives (the addition of sodium sulfate is 1.2%, the addition of phosphoric acid is 0.12%, the addition of boric acid is 0.12%, all are mass percentages), mechanically stir evenly, and cool to room temperature. The above organosilicon compound γ-carboxyethylene dimethyl hydroxysilane HOSi (CH 3 ) 2 CH 2 CH 2 COOH was added into the sulfuric acid solution (the amount of organic silicon compound added was 0.3 g / L), mechanically stirred for 5 minutes and the temperature of the sulfuric acid solution was controlled to room temperature. Then the original solution of silica gel (silicon dioxide con...

Embodiment 2

[0045] As described in Example 1, the difference is in the specific application steps: organosilicon compound γ-carboxyethylene dimethyl hydroxysilane HOSi (CH 3 ) 2 CH 2 CH 2 COOH was added in an amount of 1 g / liter.

Abstract

The invention relates to the application of organosilicon compound serving as an additive in a colloid storage battery. The organosilicon compound is of the structure of R1-Si (R2R3) R4, wherein the R1-Si group is an HO-Si group or various groups capable of being hydrolyzed into the HO-Si group, the R4 group is a group capable of obtaining hydrogen proton in an ionizing mode by the R4 group or a group capable of obtaining the hydrogen proton in an ionizing mode after being hydrolyzed; the R2 group and R3 group are various groups not affecting the stability of the organosilicon additive. By means of the organosilicon compound, the viscosity of colloid electrolyte can be improved, the glue filling time is prolonged, the internal resistance of the battery is lowered, a manufactured lead-acid battery is good in low-temperature characteristic, low in self discharge, long in service life, good in large-current discharge performance, large in high-rate discharge capacity and expected to be applied to starting of engines of vehicles, ships and airplanes, the power source of electromobiles, communication devices and the like and an emergency power source.

Description

technical field [0001] The invention relates to the application of an organosilicon compound as an additive in colloidal storage batteries, belonging to the field of colloidal storage battery additives. Background technique [0002] Lead-acid battery refers to a battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. It has the advantages of large capacity, good uniformity and stability, and has always ranked first in the output of chemical power sources. Colloidal lead-acid batteries are a major innovation of lead-acid batteries. They have the advantages of convenient transportation, no acid leakage, no acid mist, slow water consumption, long natural life, inhibition of plate corrosion and deformation, prevention of active material falling off, maintenance cycle Long and other advantages. Colloidal lead-acid batteries can not only be used as engine starters for vehicles, ships, and aircrafts, but can also be used as...
