gel battery industrial

Gel battery belongs to a development classification of lead-acid battery, the method is to add the gelling agent to sulfuric acid, so that the sulfuric acid electrolyte becomes a gel state. A battery with a gelled electrolyte is usually called a gel battery. The difference between gel battery and the conventional lead-acid battery is further developed from the initial understanding of electrolyte gelling to the research of electrochemical characteristics of electrolyte basic structure and the promotion of application in the plate grid and active substance. Its most important characteristics are: the manufacture of better quality batteries at a smaller industrial cost, its discharge curve is straight, the inflection point is high, its energy and power are more than 20% greater than conventional lead-acid batteries, and its life is generally about twice as long as conventional lead-acid batteries, and its high temperature and low-temperature characteristics are much better.

Definition
Gel batteries supplier are a developmental classification of lead-acid batteries manufacturer. In its simplest form, a gelling agent is added to sulfuric acid to change the sulfuric acid electrolyte into a gel state. A battery with a gelled electrolyte is usually called a gel battery.

Internal Structure
Broadly speaking, the difference between a gel battery and a conventional lead-acid battery does not only lie in the change of the electrolyte to a gel form. For example, an aqueous colloid in a non-solidified state is the same as a gel battery in terms of electrochemical classification structure and characteristics. Another example is the attachment of polymer materials in the plate grid, commonly known as ceramic plate grid, which can also be regarded as the application characteristics of colloidal batteries. Some laboratories have added a target coupling agent in the formulation of the electrode plate, which greatly improves the reaction utilization rate of the active material of the electrode plate, and according to non-public information, it can reach a weight-to-energy level of 70wh/kg, which are examples of the application of colloidal batteries at this stage of industrial practice and pending industrialization. An aqueous colloid is a non-disciplinary normative term to distinguish a solidified colloid.
The understanding of colloids is very different between academic classification and customary understanding. The custom mostly considers substances in a gelled physical state at room temperature as colloids, while in the chemical structure classification, it is defined as substances with a dispersed phase base structure in the range of 1-100 nm.

It is the particle size of the colloid and its surfactant that determine the electrochemical properties.
Gel batteries have sunk several times in the history, which is related to the material development and technology maturity of the gel. In the past three or two years, although nanoscale sols have been developed and more production practices have been made for the electrochemical application of surfactants, it is difficult for manufacturers to select the applicable gel state colloids in the short term.
Water-based gels are designed as an intermediate product in the development of an acid battery to a gel battery, characterized by the elimination of the physical gelling skeleton, retention of functional polymer group characteristics and surfactants, pure liquid form, used as a sulfuric acid additive, and suitable for the production of all lead batteries.

Advantages
Does not produce industrial problems common to gel batteries, the manufacturing process is exactly the same as acid batteries, increases capacity by 5-15% after use, extends battery life by 50-100%, has strong resistance to sulfation of the pole plate, and much less corrosive force on the plate grid after sulfuric acid modification. The price is also cheaper than conventional gels.
After using water-based colloid additives, there is no need to add sodium sulfate and phosphoric acid to sulfuric acid. Standard additive amount: 8% by volume.

Features
From the initial understanding of electrolyte gelling, it has further developed to the study of electrochemical properties of electrolyte infrastructure and the promotion of applications in plate grids and active substances.
The most important characteristics of gel batteries are as follows.
①: the interior of the gel battery is mainly SiO2 porous mesh structure with a large number of tiny gaps, which enables the oxygen produced by the positive electrode of the battery to migrate smoothly to the negative electrode plate and facilitate the absorption of the negative electrode for chemistry.
②: the amount of acid carried by the gel battery is larger, so its capacity is basically the same as that of AGM battery.
③: the internal resistance of the gel battery is larger, and it generally does not have better high current discharge characteristics.
④: heat is easy to spread, not easy to heat up, and the chance of thermal runaway is very small.

Basic characteristics
Adopting flat plate type pole plate and special lead paste formula, colloidal electrolyte, no liquid delamination, no need for equalization charging, stronger self-discharge rate than ordinary type lead-acid battery, battery deep discharge capacity greatly exceeds ordinary type battery, and adaptability to temperature is greatly enhanced!
