Electrolyte additive

Introduction

Electrolyte additive is an important material for electric battery. It is a material that is added to the electrolyte in electric batteries to improve its performance in electric current transmission. Recently, the development of new electrolyte additives has been rapid, and the research about them has become more and more important.

Features

From the perspective of material chemistry, electrolyte additives usually contain components such as organic and inorganic acids, bases, coal chemicals and metal salts, etc, they are generally isolated into cations and anions. Its main function is to reduce the internal resistance of the electric battery, slow the decomposition of the electrolyte, and to protect the reaction in the electric battery.

Application

At present, electrolyte additives are widely used in lithium-ion batteries, lead-acid batteries, alkaline batteries, and other electrochemical systems. In the field of lithium ion batteries, the utilization of electrolyte additives can increase the speed of charge and discharge. Also, it can enhance the cycle life of batteries by suppressing metal corrosion and suppressing side reactions. Furthermore, in the field of lead-acid batteries, the corrosion of lead alloy teams due to acidic components in the electrolyte can be effectively suppressed by the addition of electrolyte additives, thus increasing the overall safety results.

Conclusion

To sum up, the use of electrolyte additives can bring significant improvements to the properties and performance of electric batteries. Therefore, it is important to select the appropriate electrolyte additive components and optimize the formulation for the specific application. Furthermore, the new development of electrolyte additives requires further improvement and research to ensure its application in various electrochemical systems.

Electrolyte additive

Electrolyte additive, also called electrolyte additive agent, is an auxiliary additive used in electrochemical processes. It can facilitate the implementation of electrochemical processes, improve the reaction efficiency, reduce the polarity and consumption capacity, and reduce the corrosiveness of electrolytes.

The most widely used electrolyte additives are organic compounds with different polarities, such as surface active agents, polar accelerators, surfactants, leveling agents, inhibitors and so on. These additives can significantly improve the reactivity and stability of the electrolyte, and promote homogeneity in the reaction environment. They can also protect the negative electrode from reacting with the electrolyte and reduce the solubility of pitting on the surface of the anode.

In the production of batteries and energy storage devices, additives play a very important role, so it is necessary to use appropriate additives in different processes. In the production of lead-acid batteries, water-soluble antimony oxide, antimony trioxide and silicone oil are often added as additives to reduce sulfating and improve the cycle life of the battery. In the production of lithium ion batteries, additives such as fluoroethylene sulfonate, isopropanol and ethylene glycol are often added to improve the electrochemical performance of the electrolyte and increase the cycle life of the battery.

In addition, electrochemical reaction processes used in electroplating and electrodeposition processes also use electrolyte additives. Certain co-additives are added to improve the anode reactivity and reduce the electrode polarization. In addition, by adding certain head and tail fluids to the electrolyte, the stability of the electrolyte can be improved, and the settling speed of impurities can be accelerated.
