Hebei Meixi Biotechnology Co., Ltd. said that as a key component of the battery, the main functions of the battery breathable film include allowing gas to pass through, preventing electrolyte leakage, and maintaining the integrity of the battery's internal structure. The application of magnesium hydroxide in battery breathable membranes is mainly based on its unique physical and chemical properties, such as high stability, good ionic conductivity and mechanical strength.
1. Properties of magnesium hydroxide
Chemical stability: Magnesium hydroxide is not susceptible to oxidation and corrosion in harsh environments such as high temperature and high pressure, which helps to ensure the long-term stability and reliability of the battery breathable film in complex working environments.
Thermal stability: Magnesium hydroxide has a high melting point and thermal stability, which can withstand the high temperature environment inside the battery and is not easy to melt or decompose, so as to maintain the integrity and stability of the breathable film.
Ionic conductivity: Magnesium hydroxide also has a certain ionic conductivity, which helps to promote the transmission of ions inside the battery and improve the performance of the battery.
2. Application of magnesium hydroxide in battery breathable film
Improve thermal stability: Adding magnesium hydroxide to the battery breathable film can effectively improve the thermal stability of the breathable film. When the battery generates heat during charging and discharging, magnesium hydroxide is able to absorb part of the heat, reduce the temperature of the breathable film, and prevent it from being damaged due to overheating.
Enhance mechanical strength: The addition of magnesium hydroxide can also enhance the mechanical strength of the battery breathable film. This helps the vent maintain the structural integrity of the membrane when subjected to external forces, preventing safety issues such as short circuits inside the battery due to breakage.
Improved wettability: Studies have shown that magnesium hydroxide can improve the wettability of battery vents to electrolytes. This contributes to the uniform distribution and rapid transfer of the electrolyte in the breathable membrane, improving the performance and stability of the battery.
Third, the application prospects
With the rapid development of new energy technology, the performance optimization and safety improvement of batteries, as the core components of energy storage and conversion, have become a research hotspot. As one of the preparation materials for battery breathable film, magnesium hydroxide has unique advantages and broad application prospects. Researchers are constantly exploring the composite application of magnesium hydroxide and other materials and modification treatment technology to further improve its performance and application effect in battery breathable membranes.
The application of magnesium hydroxide in battery vents has significant advantages and potential. Its high stability, good ionic conductivity and mechanical strength make magnesium hydroxide a mechanism for the preparation of high-performance battery breathable films
