Insulation properties of bis(3-diylpropyl)aminoisopropyl alcohol ZR-50 in electric vehicle battery packs

Introduction

With the rapid development of electric vehicles (EVs), battery packs, as their core components, have attracted much attention. The insulation performance of the battery pack is directly related to the safety and reliability of electric vehicles. As a new insulating material, bis(3-diylpropyl)amine isopropyl alcohol ZR-50 has gradually been used in electric vehicle battery packs due to its excellent insulation properties and chemical stability. This article will introduce in detail the physical and chemical properties, insulation properties, application scenarios of ZR-50 and its specific application in electric vehicle battery packs.

1. Physical and chemical properties of bis(3-diylpropyl)aminoisopropyl alcohol ZR-50

1.1 Chemical structure

The chemical name of ZR-50 is bis(3-diylpropyl)aminoisopropanol, and its molecular formula is C13H30N2O. Its structure contains two dipropyl groups and one isopropyl alcohol group, which imparts good solubility and chemical stability to ZR-50.

1.2 Physical Properties

ZR-50 is a colorless to light yellow liquid with a lower viscosity and a higher boiling point. Its main physical properties are shown in the following table:

Properties	value
Molecular Weight	230.39 g/mol
Density	0.92 g/cm³
Boiling point	250°C
Flashpoint	120°C
Viscosity	15 mPa·s (25°C)
Solution	Easy soluble in water and organic solvents

1.3 Chemical Stability

ZR-50 has stable chemical properties at room temperature and is not easy to react with common acids and alkalis. It can maintain good stability at high temperatures and is suitable for use in high temperature environments.

2. Insulation properties of ZR-50

2.1 Insulation resistance

Insulation resistance is an important indicator for measuring the insulation performance of materials. ZR-50 has extremely high insulation resistance, its volume resistivity can reach 10^15 Ω·cm or above, and its surface resistivity is also 10^14 Ω or above. This allows the ZR-50 to maintain good insulation performance in high-voltage environments.

2.2 Dielectric constant

The dielectric constant is a measure of the ability of a material to store electrical energy in an electric field. The ZR-50 has a lower dielectric constant, about 2.5-3.0, which means its ability to store electricity in an electric field is weak, thereby reducing power loss.

2.3 Breakdown voltage

Breakdown voltage refers to a small voltage in which the material breaks down under the action of an electric field. The breakdown voltage of ZR-50 is as high as 30 kV/mm, indicating that it can maintain stable insulation performance in high voltage environments.

2.4 Heat resistance

ZR-50 has good heat resistance and its thermal decomposition temperature exceeds 300°C. This allows the ZR-50 to maintain stable insulation performance in high temperature environments and is suitable for use in electric vehicle battery packs.

3. Application of ZR-50 in electric vehicle battery packs

3.1 Selection of battery pack insulation material

Electric vehicle battery packs are usually composed of multiple battery modules, each module containing multiple battery cells. The insulating material between the battery cells needs to have high insulation, heat resistance and chemical stability. Due to its excellent insulation properties and chemical stability, ZR-50 has become an ideal choice for battery pack insulation materials.

3.2 Specific application of ZR-50 in battery pack

3.2.1 Insulation between battery cells

ZR-50 can serve as an insulating coating between battery cells to prevent short circuits between battery cells. Its high insulation resistance and low dielectric constant ensure electrical isolation between battery cells and reduces power loss.

3.2.2 Insulation between battery modules

Insulation between battery modules is equally important. The ZR-50 can act as an insulating gasket between the battery modules to prevent electrical short circuits between the modules. Its high breakdown voltage and heat resistance ensure the safety of the module in high voltage and high temperature environments.

3.2.3 Insulation of battery pack housing

The insulating material of the battery pack housing needs to have good mechanical strength and insulation properties. The ZR-50 can serve as an insulating coating for the battery pack housing, preventing short circuits between the housing and the electrical components inside the battery pack.

3.3 Application advantages of ZR-50

3.3.1 High insulation performance

The high insulation resistance and low dielectric constant of the ZR-50 ensure the safety of the battery pack in high voltage environments.

3.3.2 Good chemical stability

ZR-50 has stable chemical properties at room temperature and is not easy to react with chemical substances inside the battery pack, ensuring the long-term stability of the battery pack.

3.3.3 Excellent heat resistanceSex

The high thermal decomposition temperature of ZR-50 allows it to maintain stable insulation performance under high temperature environments, making it suitable for use in electric vehicle battery packs.

3.3.4 Easy to process

ZR-50 has low viscosity and good solubility, is easy to apply and process, and is suitable for large-scale production.

4. Comparison of ZR-50 with other insulating materials

4.1 Comparison with traditional insulating materials

Traditional insulating materials such as polytetrafluoroethylene (PTFE) and polyethylene (PE) have good insulation properties, but their heat resistance and chemical stability are poor. The ZR-50 is better than traditional insulating materials in terms of heat resistance and chemical stability, and is more suitable for use in electric vehicle battery packs.

4.2 Comparison with other new insulating materials

In recent years, some new insulating materials such as polyimide (PI) and polyether ether ketone (PEEK) have also been gradually applied to electric vehicle battery packs. Although these materials have high heat resistance and mechanical strength, their insulation properties and chemical stability are still inferior to those of ZR-50. ZR-50 has obvious advantages in insulation properties and chemical stability.

5. Future development of ZR-50

5.1 Improve insulation performance

In the future, the insulation performance of ZR-50 can be further improved through molecular structure design and synthesis process optimization, such as improving insulation resistance and breakdown voltage.

5.2 Enhance heat resistance

By introducing heat-resistant groups or combining them with other heat-resistant materials, the heat resistance of ZR-50 can be further improved, so that it can maintain stable insulation performance under higher temperature environments.

5.3 Reduce costs

At present, the production cost of ZR-50 is relatively high, limiting its large-scale application. In the future, the production cost of ZR-50 can be reduced by optimizing production processes and expanding production scale, so that it can be used more widely in electric vehicle battery packs.

Conclusion

Bis(3-diylpropyl)amine isopropyl alcohol ZR-50, as a new type of insulating material, has gradually been used in electric vehicle battery packs due to its excellent insulation properties, chemical stability and heat resistance. Its specific application in battery cells, battery modules and battery pack housing ensures the safety of the battery pack in high voltage and high temperature environments. In the future, by further improving insulation performance, enhancing heat resistance and reducing costs, the ZR-50 is expected to be widely used in electric vehicle battery packs.
