What are the common specifications for colloidal batteries?

The colloidal battery is a kind of development classification of lead-acid battery. The method is to add a coagulant in sulfuric acid to make the sulphuric acid liquid into a colloidal state. Electrolytic, colloidal batteries are often referred to as colloidal batteries. The difference between colloidal batteries and conventional lead-acid batteries has been further developed from the initial understanding of electrolyte cementation to the study of electrochemical properties of electrolyte infrastructure and its application in grid and active substances. Its most important feature is that it produces better batteries at a smaller industrial cost. Its discharge curve is straight, its inflection point is high, and its energy and power are more than 20 % larger than conventional lead-acid batteries. The life span is generally about twice that of conventional lead-acid batteries, and the characteristics of high temperature and low temperature are much better.

It is a kind of development classification of lead-acid batteries. The simplest way is to add a coagulant in sulfuric acid to make the sulfuric acid liquid into a colloidal state. Electrolytic, colloidal batteries are often referred to as colloidal batteries.

Broadly speaking, the difference between a colloidal battery and a conventional lead-acid battery is not just that the liquid is changed to a gelatinous shape. For example, non-coagulated aqueous colloids belong to the same colloidal battery from the electrochemical classification structure and characteristics. Another example is the polymer material attached to the grid, commonly known as the ceramic grid, which can also be regarded as an application feature of colloidal batteries. A targeted coupling agent has been added to the polar plate formula by the laboratory, which has greatly improved the reaction utilization rate of polar plate active substances. According to non-public data, it can reach a weight-to-energy level of 70 WH / kg. These are examples of current industrial practices and applications of colloidal batteries to be industrialized. 

Gel battery

Waterborne glue is a non-disciplinary term that is used to distinguish a name for a coagulated colloid.

The understanding of colloids, academic classification and custom understanding are very different. Customs often think that substances with a physical state of condensation at room temperature are called colloids, and in the classification of chemical structures, they are defined as substances with dispersed phase infrastructure in the range of 1-100 nm.

The electrochemical properties are determined by colloidal particle size and surfactant.

The colloidal battery has several sinks and floats in history, and it is related to the development of colloidal materials and the maturity of technology . In the past three or two years, although nanoscale Sol has been developed, there have also been more production practices for the electrochemical application of surfactants, but for manufacturers, it is difficult to select suitable gelatinous colloids in the short term.

Waterborne adhesive is an intermediate product developed from an acid battery to a colloidal battery. Its characteristics are: removing the physical gel skeleton, retaining the characteristics of functional polymer groups and surfactants, pure liquid-like, and being considered as a sulfuric acid when used. Additives, Suitable for making all lead batteries.

Advantages: There will be no common industrial problems with colloidal batteries. The manufacturing process is exactly the same as that of acid batteries. After use, the capacity will be increased by 5-15 %, the battery life will be extended by 50-100 %, and the ability to resist the salinization of polar plates will be strong. After sulfuric acid modification, the corrosion force on the grid is much smaller. The price is also cheaper than conventional colloids.

After the use of waterborne glue additives, there is no need to add sodium sulfate and phosphoric acid in sulfuric acid. Standard addition: 8 % volume-to-volume ratio.

From the initial understanding of electrolyte cementation, the electrochemical properties of electrolyte infrastructure were further developed, and the application in grid and active substances was extended. [ 1]

The most important features of colloidal batteries are the following:

1: The interior of the colloidal battery is mainly a SiO2 porous mesh structure, with a large number of tiny gaps, which can make the oxygen produced by the positive electrode of the battery smoothly migrate to the negative electrode plate, facilitating the absorption of the negative electrode;

2: The amount of acid brought by the colloidal battery is relatively large, so its capacity is basically the same as that of the AGM battery;

3: The internal resistance of colloidal batteries is relatively large, and generally does not have a good performance of large current discharge;

4: Heat is easy to spread, it is not easy to heat up, and the chance of thermal runaway is very small;

The use of plate plate and special lead paste formula, colloidal electrolyte, no liquid layer, no need for balanced charging, self-discharge rate is stronger than ordinary lead-acid batteries, battery deep discharge capacity greatly exceeds ordinary batteries, temperature adaptability is also greatly enhanced!

At present, the common colloidal batteries in China are 2 V series 50 AH ~ 3000 AH, 6 V series 100 AH \ 200 AH, 12 V series 33 AH ~ 250 AH.

Solar colloidal batteries, also known as colloidal solar batteries, whether solar colloidal batteries or colloidal solar batteries, are colloidal batteries used in solar energy products or systems. As an application branch of colloidal battery.

1 Better deep circulation ability, have good overcharge and over discharge ability.

2 long life, special process design and colloidal electrolyte ensure the long life of such batteries.

3 Applicable to different environmental requirements, colloidal solar batteries, requirements at high altitude, high temperature, low temperature and other conditions can be used normally.
